PART I.
Item 1. Business
Overview
Aptose is a science-driven biotechnology company advancing highly differentiated agents to treat unmet medical needs in life-threatening cancers, such as acute myeloid leukemia (“AML”), certain B-cell malignancies, high-risk myelodysplastic syndrome (“MDS”) and other hematologic malignancies. Aptose is a publicly listed company incorporated under the laws of Canada. The Company’s shares are listed on the Nasdaq Capital Markets and the Toronto Stock Exchange. The Company was incorporated on September 5, 1986, under the name RML Medical Laboratories (“RML”) pursuant to the Business Corporations Act (Ontario). Between 1986 and 2014, the Company operated under the names of RML, IMUTEC Corporation and Lorus Therapeutics Inc. On August 28, 2014, the Company changed its name from Lorus Therapeutics Inc. to Aptose Biosciences Inc. and, on October 1, 2014, we consolidated our outstanding common shares (the “Common Shares”) on the basis of one post-consolidation Common Share for each twelve pre-consolidation Common Shares.
Based on insights into the genetic and epigenetic profiles of certain cancers and patient populations, Aptose is building a pipeline of novel and targeted oncology therapies directed at dysregulated processes and signaling pathways in cancer cells, and this strategy is intended to optimize efficacy through simultaneous targeting of key drivers of disease in cancer cells, while preserving quality of life in patients by minimizing the side effects associated with conventional therapies. Our product pipeline includes cancer drug candidates that exert potent activity as stand-alone agents and that enhance the activities of other anticancer agents without causing overlapping toxicities. Indeed, we believe our targeted products can emerge as first-in-class or best-in-class agents that deliver single agent benefit and may serve as part of a combination therapeutic strategy for specific populations of cancer patients.
We believe the future of cancer treatment and management lies in the prospective selection and treatment of patients having malignancies that are genetically or epigenetically predisposed to response based on a drug’s unique mechanism of action. We are of the view that many drugs currently approved for the treatment and management of cancer are not selective for the specific genetic alterations (targets) and pathways that cause the patient’s tumor and hence allow for disease progression and /or significant toxicities due to off-target effects. Aptose’s strategy is to develop agents that target underlying disease-promoting mutations or altered pathways within a patient population, and we intend to apply this strategy across several therapeutic indications in oncology, including hematologic malignancies and solid tumor indications.
Aptose Programs
Aptose has two clinical-stage programs, and a third program that is discovery-stage and partnered with another company.
·CG-806, our first clinical stage program: An investigational new drug (“IND”) application was submitted February 22, 2019 to the U.S. Food and Drug Administration (“FDA”) for CG026806 (“CG-806”), Aptose’s mutation-agnostic FMS-like tyrosine kinase 3 / Bruton’s tyrosine kinase (“FLT3/BTK”) inhibitor. CG-806 is being currently evaluated in a Phase Ia/b dose escalation study in patients with certain B-cell malignancies, including chronic lymphocytic leukemia (“CLL”), small lymphocytic lymphoma (“SLL”) and certain non-Hodgkin’s lymphomas (“NHL”) that are resistant/refractory/intolerant to other therapies. The CG-806 clinical program also is planned to expand into patients with relapsed/refractory (“R/R”) acute myeloid leukemia (“R/R AML”), including the emerging populations resistant to FLT3 inhibitors.
·APTO-253, our second clinical-stage program: APTO-253 is a small molecule MYC oncogene inhibitor and we are currently enrolling patients in a Phase Ib clinical trial for the treatment of patients with R/R blood cancers, including AML and high-risk MDS.
·APL-581, our partnered program, is a dual bromodomain and extra-terminal domain motif (“BET”) protein and kinase inhibitor program which we partnered to Ohm Oncology (“OHM”) on March 7, 2018.
Aptose is committed to the development of anticancer drugs that target aberrant oncologic signaling that underlies a particular life-threatening malignancy. This targeted approach is intended to impact the disease-causing events in cancer cells without affecting normal processes within cells. Such an approach requires that we first identify critical underlying oncogenic mechanisms in cancer cells and then develop a therapeutic that selectively impacts such oncogenic mechanisms.
·As a cluster-selective kinase inhibitor, CG-806 targets multiple critical pathways that overlap to lead to the proliferation of cancer cells, including the B-cell receptor signaling pathway and FLT3 receptor pathways, as well as other receptor kinases and signaling cascades that drive dysregulated survival of the cancer cells.
·Further, Aptose created the APTO-253 small molecule targeted drug that inhibits expression of the MYC oncogene and is under development as a novel therapy for AML and related MDS. Dysregulation of the MYC oncogene reprograms signaling of cancer cells to allow for malignant transformation and resistance to typical anticancer drugs. APTO-253 directly targets the MYC gene and inhibits production of MYC mRNA and protein, thereby leading to cancer cell death.
The following table sets forth various product conditions in our pipeline and their respective stages of development.
CG-806 Program
Overview
On May 7, 2018, we exercised an option by paying $2.0 million in cash to South Korean company CrystalGenomics, Inc. (“CG”), in order to purchase an exclusive license to research, develop and commercialize CG-806 in all countries of the world except the Republic of Korea and China, for all fields of use (collectively, the “Rights”). CG-806 is a highly potent, orally bioavailable non-covalent small molecule being developed for AML and certain B-cell malignancies because of its actions as a mutation-agnostic FLT3/BTK inhibitor. Subsequently, on June 14, 2018, we announced that we entered into a license agreement with CG for Aptose to gain a license for Rights in China (including the People’s Republic of China, Hong Kong and Macau) (the “China Rights”). Under the license agreement, Aptose made an upfront payment to CG of $3.0 million for the China Rights. CG is eligible for development, regulatory and commercial-based milestones, as well as single-digit royalties on product sales in China. The total deal value for the China Rights, including the upfront payment, is up to $125 million. Aptose now owns worldwide (excluding Korea) Rights, including an issued patent in China, to CG-806, a first-in-class, highly potent oral small molecule being developed for AML, B-cell malignancies and other hematologic malignancies. Future possible royalties that might be paid under these agreements are determined on a country-by-country and product-by-product basis, on net sales during the period of time beginning on the first commercial sale of such product in such country and continuing until the later of: (i) the expiration of the last-to-expire valid claim of the CG Patents in such country covering such product; and (ii) ten (10) years after the first commercial sale of such product in such country.
CG-806 exhibits a picomolar half maximal inhibitory concentration (IC50) toward FLT3 with the Internal Tandem Duplication (“FLT3-ITD”), potency against the wild type FLT3 and a host of mutant forms of FLT3, as well as single-digit nanomolar IC50’s against BTK and its C481S mutant (“BTK-C481S”). Consequently, CG-806 is characterized as a mutation-agnostic FLT3/ BTK inhibitor. Further, CG-806 suppresses a small group of other relevant oncogenic kinases/pathways (including CSF1R, PDGFRα, TRK, and the ERK, MYC, AKT/mTOR/S6K and AURK/H3S10 pathways) that are operative in AML and certain B cell malignancies, but does not inhibit the TEC, EGFR and ErbB2/4 kinases that are responsible for safety concerns with certain other kinase inhibitors.
As a potent inhibitor of FLT3-ITD, CG-806 may become an effective therapy in a high-risk subset of AML patients. This is because the FLT3-ITD mutation occurs in approximately 30% of patients with AML and is associated with a poor prognosis. In murine xenograft studies of human AML (FLT3-ITD), CG-806 administered orally resulted in tumor elimination (“cures”) without measurable toxicity. Importantly, CG-806 targets other oncogenic kinases which may also be operative in FLT3-ITD AML, thereby potentially allowing the agent to become an important therapeutic option for a broader group of this difficult-to-treat AML patient population. The findings that CG-806 targets all forms of FLT3 and several other key oncogenic pathways, and that CG-806 was well tolerated from a safety perspective during efficacy and formal Good Laboratory Practice (“GLP”) toxicology studies, suggest that CG-806 may also have applicability in treating patients, particularly those over the age of 65, who cannot tolerate other therapies.
Separate from the AML and FLT3 story, CG-806 may be a preferable treatment for patients with B cell malignancies over alternatives such as ibrutinib or other commercially approved or development stage BTK inhibitors in certain circumstances. Overexpression of the BTK enzyme can drive oncogenic signaling of certain B cell malignancies, including chronic lymphocytic leukemia (“CLL”) and certain NHL such as mantle cell lymphoma (“MCL”), diffuse large cell B cell lymphoma (“DLBCL”) and others. Therapy of these patients with covalent, irreversible BTK inhibitors, such as ibrutinib, that target the active site cysteine (“Cys”) residue of BTK can be beneficial in many patients. However, therapy with covalent BTK inhibitors can select for BTK with a C481S mutation, thereby conferring resistance to covalent BTK inhibitors. Furthermore, approximately half of CLL patients have discontinued treatment with ibrutinib after 3.4 years of therapy. Discontinuation of ibrutinib is due to the development of drug resistance (in particular, patients have malignancies that developed the BTK-C481S mutation), or due to refractory disease (patient tumors did not respond to ibrutinib) or intolerance (side effects led to discontinuation of ibrutinib), according to a study performed at The Ohio State University. The C481S mutation is observed in 5-10% of the patients, while 40-45% of the patients were intolerant or refractory to ibrutinib. As a non-covalent, reversible inhibitor of BTK, CG-806 does not rely on the Cysteine 481 residue (“C481”) for inhibition of the BTK enzyme. Indeed, recent X-ray crystallographic studies (with wild type and C481S BTK) demonstrated that CG-806 binds productively to the BTK active site in a manner that is indifferent to the presence or absence of mutations at the 481 residue. Moreover, in vitro studies demonstrated that CG-806 kills B cell malignancy cell lines on average approximately 1000 times more potently than ibrutinib and kills ibrutinib-resistance cancer cells, and that CG-806 more potently killed primary malignant cells taken from the bone marrow of CLL and ALL B-cell cancer patients. Yet, CG-806 demonstrated a high degree of safety in animal efficacy and GLP toxicology studies. Consequently, patients who are resistant, refractory or intolerant to ibrutinib or other commercially approved or development-stage BTK inhibitors with B cell malignancies may continue to be sensitive to CG-806 therapy. This is particularly true since CG-806 inhibits the wild type and mutant forms of BTK, as well as other kinases/pathways that drive the survival and proliferation of B cell malignancies.
Role of BTK in B-cell signaling
BTK, a member of the TEC family kinase, is an essential element of B-cell receptor (“BCR”) signaling, which is required for B-cell maturation, survival and proliferation. It is an upstream activator of multiple pro-survival / anti-apoptotic pathways, including the NF-KB, mTOR-AKT, RAS, ERK and MAPK pathways. BTK is overexpressed in malignant cells from patients with various B-cell malignancies, such as CLL, MCL, AML, and DLBCL. Disruption of BCR signaling via inhibition of BTK, has been shown to lead to clinical remissions in these patients.
CG-806 as a Non-covalent, Reversible Kinase Inhibitor
Binding studies of CG-806 have confirmed non-covalent, reversible inhibition of BTK, FLT3-ITD and Aurora Kinase A. Ibrutinib, a commercially-approved, covalent BTK inhibitor, possesses a Michael acceptor to react with C481 in BTK and irreversibly inactivates the BTK enzyme. In contrast, CG-806 does not require reactivity with the C481 residue for inhibition of the BTK enzyme, thereby allowing CG-806 to inhibit the wild type and C481 mutant form of the BTK enzyme.
Preclinical In Vitro Evaluation of CG-806
CG-806 is a potent inhibitor of BTK and FLT3 wild types, as well as the BTK C481S and FLT3-ITD mutants, which are strongly associated with clinical relapse or are negative prognostic factors in patients. In enzymatic assays, CG-806 has demonstrated potency against the BTK C481S mutant with a half maximal IC50 of 2.5 nanomolar (nM). CG-806 also has potent activity against the FLT-ITD mutation, occurring in 30-35% of AML patients, with an IC50 against the purified enzyme of 0.8nM (800pM). Likewise, CG-806 exerts low nM IC50 values against the FLT3 enzyme having various mutations in the tyrosine kinase domain (TKD) and the Gatekeeper region, and CG-806 has the ability to potently suppress the CSF1R, PDGFRα, AKT/mTOR/S6K, ERK, MAPK, MYC and AURK/H3S10 pathways. Finally, CG-806 does not exhibit any inhibition of epidermal growth factor receptor (“EGFR”), TEC or ErbB2/4 kinases. Inhibition of one or more of these kinases has been speculated to contribute to the toxicity observed from the commercially approved BTK inhibitor.
BTK is overexpressed in the blast cells of approximately 80% of AML patients as compared to normal peripheral blood mononuclear cells (“PBMCs”) in healthy subjects. Researchers have shown that BTK inhibition attenuates the proliferation and survival of FLT3-ITD primary AML blasts and AML cell lines, as well as inhibits the downstream activation of FLT3-ITD-dependent MYC and STAT5 kinases. We believe that CG-806 is the only drug in development that inhibits both FLT3-ITD and BTK pathways reported to synergize to drive the proliferation and survival of AML.
CG-806 Xenograft Studies
In vivo subcutaneous AML tumor models of anti-cancer efficacy revealed CG-806 induced rapid and sustained tumor eradication (Figure 1a). CG-806 was administered orally once daily, for 14 days. Moreover, CG-806 exhibited the sustained tumor elimination post therapy, while demonstrating no impact to murine body weight, no impacts to hematology cell counts or visible organ toxicities - necropsy and clinical pathology findings did not reveal any abnormal observations. A maximum tolerated dose has not yet been identified with murine xenograft studies.
Figure 1a. Efficacy of CG-806 in MV4-11 xenograft model.
MV4-11 tumor bearing mice were administered an oral suspension once daily for 14 days of CG-806 at 2 mg/kg (red line), 10 mg/kg (green line) or 100 mg/kg (purple line), Ibrutinib, 12 mg/kg (black line), or Vehicle Control (light blue line) with 7-day post-treatment follow-up. Tumor volumes and body weights were measured 3 times weekly.
In a separate MV4-11 xenograft study (Figure 1b), the antitumor efficacy of CG-806 and mouse survival over 120 days were evaluated when mice were treated orally for 28 consecutive days with CG 806 at dose levels of 0 (vehicle only, red), 10 (olive), 30 (green), 100 (blue), or 300 mg/kg (magenta). In this study, the clinical formulation (CG-806 co-micronized with 2.5% sodium lauryl sulfate (SLS) and the dosing schedule (“BID”) planned for human clinical studies were utilized. CG-806 produced slower tumor growth and extended survival at the 10 and 30mg/kg dose levels, while 100% cure rates were achieved at the 100 and 300 mg/kg dose levels (11/11 mice survived in the latter two groups). Moreover, no signs of toxicity were noted at any dose level.
Figure 1b. CG-806 Extends Survival in a Dose-Dependent Way in MV4-11 AML Xenograft Mouse Model Following Oral BID Dosing for 28 Consecutive Days.
Although the above murine xenograft models demonstrate potent antitumor activity with no observed toxicity, the models utilize an AML cell line rather than cells derived from an AML patient. In a study performed at the University of Texas MD Anderson Cancer Center (“MDACC”), the efficacy of CG-806 was evaluated in a patient derived xenograft (“PDX”) model (Figure 1c). Bone marrow cells were collected from an AML patient that had relapsed on a clinical trial. The patient entered the trial with FLT3-ITD AML and was placed on sorafenib and azacytidine. After one cycle, the patient had a complete response but then relapsed after cycle 3. Genetic analysis demonstrated that the AML cells had acquired a second mutation in AML, and this was the D835 mutation, making the patient dual mutant FLT3-ITD/D835. Bone marrow cells from the patient (AML FLT3-ITD/D835) were implanted in mice to establish a PDX model. Expansion of the human AML cells in the bone marrow and peripheral blood of the mice took approximately one month. In the vehicle (15% Transcutol HP/85% PEG-400) treated mice, the leukemic burden in the peripheral blood increased from day 31 through day 50 and beyond. However, treatment with 100 mg/kg CG-806 (orally daily for 5 consecutive days followed by 2 days off every week), resulted in significant reduction in the leukemic burden and reductions in splenomegaly at 52 days post-implantation. These data suggest CG-806 may be used to treat patients whose disease has become resistant to other FLT3 inhibitors.

APTO-253 Program
Overview
APTO-253, our second clinical-stage program, is a novel small molecule therapeutic agent that inhibits expression of the MYC oncogene, leading to cell cycle arrest and programmed cell death (apoptosis) in human-derived solid tumor and hematologic cancer cells, without causing general myelosuppression of the healthy bone marrow. The MYC oncogene is overexpressed in hematologic cancers, including AML. MYC is a transcription factor that regulates cell growth, proliferation, differentiation and apoptosis, and overexpression amplifies new sets of genes to promote oncogenesis. APTO-253 dramatically down-regulates expression of the MYC oncogene in AML cells and depletes those cells of the MYC oncoprotein, leading to apoptotic cell death in AML cells. Thus APTO-253 may serve as safe and effective MYC inhibitor for AML that combines well with other agents and does not impact the normal bone marrow.
During 2015, we were evaluating APTO-253 in a Phase Ib clinical trial in patients with relapsed / refractory hematologic malignancies, particularly AML and MDS, before being placed on clinical hold by the FDA in November 2015. The Phase Ib trial was placed on clinical hold in order to solve a chemistry-based formulation issue, and the chemistry of the API and the formulation underwent minor modifications to deliver a stable and soluble drug product for return to the clinical setting. In December 2016, we announced that we had successfully manufactured multiple non-GMP batches of a new drug product formulation for APTO-253, including a batch that had been stable and soluble for over six months. However, the 40L batch that was the intended clinical supply encountered an unanticipated mishap during the filling process that compromised the stability of that batch of drug product. On January 23, 2017, we announced that the root cause and corrective action studies would take longer than originally expected and that we would temporarily delay clinical activities with APTO-253 in order to elucidate the cause of manufacturing mishap, with the intention of restoring the molecule to a state supporting clinical development and partnering. Formal root cause analyses studies were completed to identify the reason for the drug product stability failure, and a correction action was implemented. We then manufactured a new GMP clinical supply of drug product and performed the studies required to demonstrate the fitness of the drug product for clinical usage, and presented the findings to the FDA in the second quarter of 2018. On June 28, 2018, the FDA notified us that it had lifted the clinical hold on APTO-253. This was followed by resubmission of the revised clinical protocol to Institutional Review Boards (“IRB”) at multiple clinical sites.
On November 28, 2018, we announced that we dosed the first patient in the re-initiation of the Phase Ib Clinical Study of APTO-253. Since then, we have completed the first three dose cohorts (20mg/m2, 40mg/m2 and 66mg/m2) and are currently dosing patients in the fourth dose cohort at 100mg/m2 dose level. In the patients we have dosed at the first three dose levels, we observed meaningful reductions in MYC expression in the patient PBMC samples and noted that the drug product is well tolerated to date.
APTO-253 Studies on Solid Tumors
In January 2011, Aptose announced the first patient enrollment in a Phase I dose-escalation study for APTO-253 in patients with advanced or metastatic solid tumors who are unresponsive to conventional therapy or for whom no effective therapy is available. The study was initially being conducted at Memorial Sloan-Kettering Cancer Center in New York. Objectives of the study included determination or characterization of the safety profile, maximum tolerated dose, and antitumor activity of APTO-253, as well as pharmacokinetics and a recommended Phase II dose for subsequent clinical trials.
In June 2012, MDACC in Houston was added as a second site under the direction of Dr. Jennifer Wheler as the principal investigator. In addition, Aptose announced that the study had successfully completed the accelerated drug dose escalation stage (Stage 1), with further escalation under way in the non-accelerated dose escalation stage (Stage 2) for the purpose of determining the maximal tolerated dose level and recommended Phase II dose. The addition of a second site expanded patient availability for enrollment.
In January 2013, Aptose announced that Phase I clinical study of APTO-253 had successfully escalated to the target dose level based on predicted and observed clinical effects without limitation by toxicity. The success of this study allowed Aptose to initiate a biomarker clinical investigation to further explore the effects of the drug at relevant doses determined in the clinical trial.
In April 2013, Aptose announced that studies demonstrated the antitumor activity of APTO-253 in animal models of human NSCLC with a dose-response effect in NSCLC.
In July 2013, Aptose announced the results of the Phase I clinical trial of APTO-253. In this first-in-man dose-escalation clinical study, APTO-253 demonstrated a favorable safety profile, as well as encouraging signs of antitumor activity in patients with solid tumors. The design of this trial consisted of APTO-253 as a single agent in patients with advanced solid tumors resistant to multiple standard therapies. The study enrolled 27 patients, all of which had failed a median of four prior chemotherapies. Although this was primarily a dose-escalation safety study, efficacy and pharmacokinetics were also explored.
The clinical trial enrolled patients at seven dose levels ranging from 20 to 229 mg/m2. Of the 27 patients enrolled, 17 were evaluable for efficacy. Of these 17 patients, seven (41%) achieved stable disease by Response Evaluation Criteria In Solid Tumors (“RECIST”). This included patients with colorectal, lung, appendiceal, liver and uterine cancers. Dose related activity was demonstrated at the higher dose levels (176 and 229 mg/m2). At these two highest dose levels, four of five evaluable patients (80%) achieved sustained stable disease by RECIST ranging from 5.6 months to 8 months, representative of disease control. Of these, a patient with non-small cell lung cancer at the highest dose level additionally demonstrated non-index tumor shrinkage.
The safety assessment indicated that APTO-253 was well tolerated at all dose levels tested in this trial. The dose escalation was not limited by toxicity. The most common adverse event was Grade 1 or 2 fatigue seen in three patients. There was one Grade 3 toxicity, asymptomatic low blood phosphate level that was reversible by supplementation with phosphates. The pharmacokinetic profile was consistent with the predictive profile seen preclinically, and the elimination profile and half-life in patients were suggestive of a very rapid distribution phase and prolonged retention. No further studies were performed by the prior administration of Aptose following the arrival of the new administration in late 2013.
APL-581 Program
In November 2015, Aptose announced an exclusive drug discovery partnership with Laxai Avanti Life Sciences (“LALS”) for their expertise in next generation epigenetic-based therapies. Under the agreement, LALS was to be responsible for developing multiple clinical candidates, including optimizing candidates that exert dual BRD4 / kinase inhibitory activity. Based on available resources, Aptose halted further investment in the collaboration with LALS in late 2016. However, the program delivered novel intellectual property and hit molecules (such as APL-581). Consequently, Aptose chose to out-license the program.
On March 7, 2018, Aptose entered into an exclusive global license agreement with OHM, an affiliate of LALS that was formed in 2016 to advance the clinical development of compelling molecules derived from the LALS initiative, for the development, manufacture and commercialization of APL-581, as well as related molecules, from Aptose’s dual BET protein and kinase inhibitor program. Under the agreement, Aptose retained reacquisition rights to certain molecules, while OHM/LALS has the rights to develop and sublicense all other molecules. Aptose received a nominal upfront cash payment and is eligible to receive up to $125 million of additional payments based on the achievement of certain developmental, regulatory and sales milestones, as well as significant royalties on future sales generated from the program, if any. We have not received any milestone or royalty payments pursuant to this agreement. Future possible royalties that might be paid by Ohm to Aptose under these agreements are determined on a country-by-country and product-by-product basis, on net sales during the period of time beginning on the first commercial sale of such product in such country and continuing until the later of: (i) the expiration of the last-to-expire valid claim of the CG Patents in such country covering such product; and (ii) ten (10) years after the first commercial sale of such product in such country.
Competitive Conditions
The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and intense competition. There are numerous companies in these industries that are focusing their efforts on activities similar to ours. Some of these are companies with established positions in the pharmaceutical industry and may have substantially more financial and technical resources, more extensive research and development capabilities, and greater marketing, distribution, production and human resources than Aptose. In addition, we face competition from other companies for opportunities to enter into partnerships with biotechnology and pharmaceutical companies and academic institutions.
Competition with our potential products may include chemotherapeutic agents, monoclonal antibodies, antisense therapies, small molecules, immunotherapies, vaccines and other biologics with novel mechanisms of action. These drugs may kill cancer cells indiscriminately, or through a targeted approach, and some have the potential to be used in non-cancer indications. We also expect that we will experience competition from established and emerging pharmaceutical and biotechnology companies that have other forms of treatment for the cancers that we target, including drugs currently in development for the treatment of cancer that employ a number of novel approaches for attacking these cancer targets. Cancer is a complex disease with more than 100 indications requiring drugs for treatment. The drugs in competition with our potential drugs have specific targets for attacking the disease, targets which are not necessarily the same as ours. These competitive drugs, however, could potentially also be used together in combination therapies with our drugs to manage the disease. Other factors that could render our potential products less competitive may include the stage of development, where competitors’ products may achieve earlier commercialization, as well as superior patent protection, better safety profiles, or a preferred cost-benefit profile.
CG-806 Treatment for B Cell Malignancies
We are aware of a number of companies that have developed and are pursuing different approaches to BTK inhibition, both for the wild type and to the C481S-mutant forms. Companies that have developed approved or are currently developing inhibitors that directly target the wild type include AbbVie (IMBRUVICA) and AstraZeneca (CALQUENCE) and Beigene Co., Ltd. (Zanubrutinib).
Others that are developing inhibitors that target the C481S-mutant BTK include Merck (ARQ 531), Roche, Sunesis Pharmaceuticals (vecabrutinib) and Eli Lilly (LOXO-305) among others.
CG-806 and APTO-253 for AML
We also face intense competition in AML as there is a wide range of therapies that have been approved and are under development for the treatment of AML. Companies that have developed approved or are currently developing non-targeted therapies include Jazz (VYXEOS), Pfizer (MYLOTARG) and AbbVie (VENCLEXTA), among others. Others that have developed or are developing highly targeted therapies such as FLT3 include Novartis (RYDAPT), Astellas (XOSAPTA), Daiichi Sankyo (quizartinib), Arog (crenolanib), and IDH1/2 include Agios (TIBSOVO) and Celgene/BMS (IDHIFA) among others.
Manufacturers, Suppliers and Other Third Party Contractors
Contract manufacturing organizations (“CMOs”) manufacture our product candidates for all preclinical studies and clinical trials. We rely on CMOs for manufacturing, filling, packaging, storing and shipping of drug product in compliance with Current Good Manufacturing Practice (“cGMP”) regulations applicable to our products. The FDA ensures the quality of drug products by carefully monitoring drug manufacturers’ compliance with cGMP regulations. The cGMP regulations for drugs contain minimum requirements for the methods, facilities and controls used in manufacturing, processing and packing of a drug product. These CMOs are reputable companies active in the biotechnology industry. Pricing is predictable as there are many alternatives of such supplies that are readily available.
We rely and will continue to rely on third party contract research organizations (“CROs”) to conduct a significant portion of our preclinical and clinical development activities. Preclinical activities include in vivo studies providing access to specific disease models, pharmacology and toxicology studies, and assay development. Clinical development activities include trial design, regulatory submissions, clinical patient recruitment, clinical trial monitoring, clinical data management and analysis, safety monitoring and project management, contract manufacturing and quality assurance.
Intellectual Property
We believe that our issued patents and pending applications are important in establishing and maintaining a competitive position with respect to our products and technology.
CG-806
A Patent Cooperation Treaty (“PCT”) application providing composition of matter and use protection for CG-806 was filed in late 2013, with a potential expiry in 2033 before extension opportunities, across all major geographies
In May 2018, we paid $2.0 million in cash and licensed the rights to CG-806, for all fields of use, in all territories outside of the Republic of Korea and China, by exercising an option we obtained through a June 2016 option-license agreement with South Korean company CrystalGenomics, Inc. (“CG”) that had granted us an exclusive option to research, develop and commercialize (collectively, the “Rights”) CG-806.
In June 2018, we entered into a separate license agreement with CG for Aptose to gain a license for Rights to CG-806 in the People’s Republic of China, Hong Kong and Macau (the “China Rights”). This license agreement was formally executed by Aptose through an upfront payment to CG of $3.0 million for the China Rights. CG is eligible for payments upon the achievement of developmental, regulatory and commercial-based milestones, as well as single-digit royalties on product sales in China. Aptose now owns worldwide Rights to CG-806, including an issued patent in China but excluding any Rights in Korea.
US Patent No. 9,758,508

Environmental Protection
The Company’s research and development activities involve the controlled use of hazardous and radioactive materials and, accordingly, the Company is subject to federal, provincial and local laws and regulations in the United States and Canada governing the use, manufacture, storage, handling and disposal of such materials and certain waste products. To the knowledge of the Company, compliance with such environmental laws and regulations does not and will not have any significant impact on its capital spending, profits or competitive position within the normal course of its operating activities. There can be no assurance, however, that the Company will not be required to incur significant costs to comply with environmental laws and regulations in the future or that its operations, business or assets will not be materially adversely affected by current or future environmental laws or regulations.
Employees
As at December 31, 2019, we employed 31 full-time persons and two part-time persons in research and drug development and administration activities. Seven of our employees hold Ph.Ds. and numerous others hold degrees and designations such as MD, MSc, BSc, CPA (CA), CPA (California) and MBA. To encourage a focus on achieving long-term performance, employees and members of the board of directors of the Company (the “Board”) have the ability to acquire an ownership interest in the Company through Aptose’s share option and alternate compensation plans. Of note, in January of 2020, Aptose hired a Chief Medical Officer holding an MD and a PhD.
The business of the Company requires personnel with specialized skills and knowledge in oncology. Researchers must be able to design and implement studies to assess the efficacy of anticancer drugs. Specialized knowledge and skills relating to chemistry and formulation process development are also needed. Such knowledge and skills are needed to develop product specific analytical methods and formulation processes. The Company’s business also requires clinical and regulatory expertise and knowledge. The Company has trained scientists and personnel with broad experience in these fields.
None of our employees are unionized, and we consider our relations with our employees to be good.
Government Regulation
Overview
Our overall regulatory strategy is to work with the appropriate government departments which regulate the use and sale of therapeutic drug products. This includes the FDA in the United States, Health Canada in Canada, the European Medicines Agency in Europe, and other local regulatory agencies with oversight of preclinical studies, clinical trials and marketing of therapeutic products. Where possible, we intend to take advantage of opportunities for accelerated development of drugs designed to treat rare and serious or life-threatening diseases. We also intend to pursue priority evaluation of any application for marketing approval filed in Canada, the United States or the European Union and to file additional drug applications in other markets where commercial opportunities exist. We may not be able to pursue these opportunities successfully.
Regulation(s) by government authorities in the United States, Canada, and the European Union are significant factors in guiding our current research and drug development activities. To clinically test, manufacture and market drug products for therapeutic use, we must be in compliance with guidance and regulations established by the regulatory agencies in the countries in which we currently operate or intend to operate.
The laws of most of these countries require the licensing of manufacturing facilities, carefully controlled research and the extensive testing of products. Biotechnology companies must establish the safety and efficacy of their new products in clinical trials; they must establish and comply with cGMPs for the manufacturing of the product and control over marketing activities before being allowed to market a product. The safety and efficacy of a new drug must be shown through human clinical trials of the drug carried out in accordance with the guidance and regulations established by local and federal regulatory agencies.
The process of completing clinical trials and obtaining regulatory approval for a new drug takes a number of years and requires the expenditure of substantial resources. Once a new drug or product license application is submitted, regulatory agencies may not review the application in a timely manner and may not approve the product. Even after a New Drug Application (“NDA”) submission has occurred and/or approval has been obtained, further studies, including post-marketing studies, may be required to provide additional data on the efficacy and safety necessary to confirm the approved indication or to gain approval for the use of the new drug as a treatment for clinical indications other than those for which the new drug was initially tested. Also, regulatory agencies require post-marketing surveillance programs to monitor a new drug’s side effects, safety and long-term effects of the product. A serious safety or effectiveness problem involving an approved new drug may result in a regulatory agency mandating a withdrawal of the new drug from the market and possible civil action. It is possible that we could encounter such difficulties or excessive costs in our efforts to secure necessary approvals, which could delay or prevent us from manufacturing or marketing our products.
In addition to the regulatory product approval framework, biotechnology companies, including Aptose, are subject to regulation under local, provincial, state and federal law, including requirements regarding occupational safety, laboratory practices, environmental protection and hazardous substance control, and may be subject to other present and future local, provincial, state, federal and foreign regulation, including possible future regulation of the biotechnology industry.
Approval of New Drugs in Canada
In Canada, the manufacture and sale of new drugs are controlled by Health Canada. New drugs must pass through a number of testing stages, including pre-clinical testing and human clinical trials. Pre-clinical testing involves testing the new drug’s chemistry, pharmacology and toxicology in vitro and in vivo. Successful results (that is, potentially valuable pharmacological activity combined with an acceptable low level of toxicity) enable the developer of the new drug to file a clinical trial application to begin clinical trials involving humans.
To study a drug in Canadian patients, a clinical trial application submission must be filed with Health Canada. The clinical trial application submission must contain specified information, including the results of the pre-clinical tests completed at the time of the submission and any available information regarding use of the drug in humans. In addition, since the method of manufacture may affect the efficacy and safety of a new drug, information on manufacturing methods and standards and the stability of the drug substance and dosage form must be presented. Production methods and quality control procedures must be in place to ensure an acceptably pure product, essentially free of contamination, and to ensure uniformity with respect to all quality aspects.
In addition, all federally regulated trials must be approved and monitored by an independent committee of doctors, scientists, advocates and others to ensure safety and ethical standards. These committees are called Institutional Review Boards (IRBs) or Ethics Review Boards (“ERBs”). The review boards study and approve all study-related documents before a clinical trial begins and also carefully monitor data to detect benefit or harm, and validity of results.
Provided Health Canada does not reject a clinical trial application submission and IRB or ERB approval has been obtained, clinical trials can begin. Clinical trials for product candidates in Canada, as in the United States, are generally carried out in three phases. Phase I involves studies to evaluate toxicity and ideal dose levels in healthy humans. The new drug is administered to human patients who have met the clinical trial entry criteria to determine pharmacokinetics, human tolerance and prevalence of any adverse side effects. Phases II and III involve therapeutic studies. In Phase II, efficacy, dosage, side effects and safety are established in a small number of patients who have the disease or disorder that the new drug is intended to treat. In Phase III, there are controlled clinical trials in which the new drug is administered to a large number of patients who are likely to receive benefit from the new drug. In Phase III, the effectiveness of the new drug in patients is compared to that of standard accepted methods of treatment in order to provide sufficient data for the statistical proof of safety and efficacy for the new drug.
If clinical studies establish that a new drug has value, the manufacturer submits a new drug submission application to Health Canada for marketing approval. The new drug submission contains all information known about the new drug, including the results of pre-clinical testing and clinical trials. Information about a substance contained in new drug submission includes its proper name, its chemical name, and details on its method of manufacturing and purification, and its biological, pharmacological and toxicological properties. The new drug submission also provides information about the dosage form of the new drug, including a quantitative listing of all ingredients used in its formulation, its method of manufacture, manufacturing facility information, packaging and labelling, the results of stability tests, and its diagnostic or therapeutic claims and side effects, as well as details of the clinical trials to support the safety and efficacy of the new drug. Furthermore, for biological products, an on-site evaluation is completed to assess the production process and manufacturing facility. It is required prior to the issuance of a notice of compliance. All aspects of the new drug submission are critically reviewed by Health Canada. If a new drug submission is found satisfactory, a notice of compliance is issued permitting the new drug to be sold for the approved use. In Canada, an establishment license must be obtained prior to marketing the product.
Health Canada has a policy of priority evaluation of new drug submissions for all drugs intended for serious or life-threatening diseases for which no drug product has received regulatory approval in Canada and for which there is reasonable scientific evidence to indicate that the proposed new drug is safe and may provide effective treatment.
An exception to the foregoing requirements relating to the manufacture and sale of a new drug is the limited authorization that may be available in respect of the sale of new drugs for emergency treatment. Under the special access program, Health Canada may authorize the sale of a quantity of a new drug for human use to a specific practitioner for the emergency treatment of a patient under the practitioner’s care. Prior to authorization, the practitioner must supply Health Canada with information concerning the medical emergency for which the new drug is required, such data as is in the possession of the practitioner with respect to the use, safety and efficacy of the new drug, the names of the institutions at which the new drug is to be used and such other information as may be requested by Health Canada. In addition, the practitioner must agree to report to both the drug manufacturer and Health Canada the results of the new drug’s use in the medical emergency, including information concerning adverse reactions, and must account to Health Canada for all quantities of the new drug made available.
The Canadian regulatory approval requirements for new drugs outlined above are similar to those of other major pharmaceutical markets. While the testing carried out in Canada is often acceptable for the purposes of regulatory submissions in other countries, individual regulatory authorities may request supplementary testing during their assessment of any submission. Therefore, the clinical testing conducted under Health Canada authorization or the approval of regulatory authorities of other countries may not be accepted by regulatory authorities outside Canada or other countries.
Approval of New Drugs in the United States
In the United States, the FDA controls and investigates the investigation, manufacturing, and sale of new drugs. New drugs require FDA approval of a NDA prior to commercial sale. In the case of certain biological products, a Biological License Application (“BLA”) must be obtained prior to marketing and batch releasing. As in Canada, to obtain marketing approval, data from adequate and well-controlled human clinical trials, demonstrating to the FDA’s satisfaction a new drug’s safety and effectiveness for its intended use, are required. Data are generated in studies conducted pursuant to an IND submission, similar to that required for a clinical trial application in Canada. Clinical trials with human subjects are characterized as Phase I, Phase II and Phase III trials or a combination thereof. In a marketing application, the manufacturer must also demonstrate the identity, potency, quality and purity of the active ingredients of the new drug involved, and the stability of those ingredients. Further, the manufacturing facilities, equipment, processes and quality controls for the new drug must comply with the FDA’s current cGMP regulations for drugs both in a pre-licensing inspection before product licensing and in subsequent periodic inspections after licensing. An establishment license grants the sponsor permission to fabricate, package, label, distribute, import, wholesale or test the newly approved drug.
Federally regulated trials must be approved and monitored by an independent committee of doctors, scientists, advocates and others to ensure safety and ethical standards. These committees are called IRBs or ERBs. The review boards study and approve all study-related documents before a clinical trial begins and also carefully monitor data to detect benefit or harm, and validity of results.
Post-Approval Regulation
The monitoring of a new drug does not cease once it is on the market. For example, a manufacturer of a new drug must report any new information received concerning serious side effects, as well as the failure of the new drug to produce desired effects. If Health Canada determines it to be in the interest of public health, a notice of compliance for a new drug may be suspended and the new drug may be removed from the market.
A post surveillance program involves clinical trials conducted after a drug is marketed (referred to as Phase IV studies in the United States) and is an important source of information on as yet undetected adverse outcomes, especially in populations that may not have been involved in the premarketing trials (e.g., children, the elderly, pregnant women) and the drug’s long-term morbidity and mortality profile. Regulatory authorities may require companies to conduct Phase IV studies as a condition of market approval. Companies often conduct post-marketing studies in the absence of a regulatory mandate.
The foregoing description is a brief summary of the requirements for a new drug to be approved for marketing in North America. The European Medicines Agency and Japanese Pharmaceuticals and Medical Devices Agency are also important regulatory authorities in drug development. Together with the FDA, they are the three International Conference on Harmonization parties which oversee the three largest markets for drug sales.

ITEM 1A. RISK FACTORS
Risk Factors and Uncertainties
Any of the risks and uncertainties described below could significantly and negatively affect our business, prospects, financial condition, operating results, or credit ratings, which could cause the trading price of our Common Shares to decline. Additional risks and uncertainties not presently known to us, or risks that we currently consider immaterial, could also impair our business operations or financial condition. The following discussion of risk factors contains “forward-looking” statements, as discussed above.
Risks Related to our Business
We are an early stage development company with no significant revenues from product sales.
We are at an early stage of development. In the past five years, none of our potential products has obtained regulatory approval for commercial use and sale in any country and as such, no significant revenues have resulted from product sales. Significant additional investment will be necessary to complete the development of any of our product candidates. Preclinical and clinical trial work must be completed before our potential products could be ready for use within the markets that we have identified. We may fail to develop any products, obtain regulatory approvals, enter clinical trials or commercialize any products. We do not know whether any of our potential product development efforts will prove to be effective, meet applicable regulatory standards, obtain the requisite regulatory approvals, be capable of being manufactured at a reasonable cost or be accepted in the marketplace. We also do not know whether sales, license fees or related royalties will allow us to recoup any investment we make in the commercialization of our products.
The product candidates we are currently developing are not expected to be commercially viable for at least the next several years and we may encounter unforeseen difficulties or delays in commercializing our product candidates. In addition, our potential products may not be effective or may cause undesirable side effects.
Our product candidates require significant funding to reach regulatory approval assuming positive clinical results. For example, our product candidate APTO-253 began enrollment in a Phase Ib clinical trial in patients with relapsed or refractory AML and high risk MDS and was placed on clinical hold by the FDA following a voluntary suspension of dosing by us. That hold has been lifted, but significant additional funding will be necessary to complete the restarted Phase Ib clinical and, if required, Phase II or Phase III clinical trials. Similarly, we have received FDA approval to initiate a Phase I clinical trial with our product candidate CG-806 for patients with B-cell malignancies. Significant additional capital will be necessary to complete the Phase I clinical trial, and if required, Phase II or Phase III clinical trials. Such funding for our product candidates may be difficult, or impossible to raise in the public or private markets or through partnerships. If funding or partnerships are not readily attainable, the development of our product candidates may be significantly delayed or stopped altogether. The announcement of a delay or discontinuation of development would likely have a negative impact on our share price.
We need to raise additional capital.
We have an ongoing need to raise additional capital. To obtain the necessary capital, we must rely on some or all of the following: additional share issues, debt issuances (including promissory notes), collaboration agreements or corporate partnerships and grants and tax credits to provide full or partial funding for our activities. Additional funding may not be available on terms that are acceptable to us or in amounts that will enable us to carry out our business plan.
Our need for capital may require us to:
·engage in equity financings that could result in significant dilution to existing investors;
·delay or reduce the scope of or eliminate one or more of our development programs;
·obtain funds through arrangements with collaborators or others that may require us to relinquish rights to technologies, product candidates or products that we would otherwise seek to develop or commercialize ourselves;
·license rights to technologies, product candidates or products on terms that are less favorable to us than might otherwise be available;
·considerably reduce operations; or
·cease our operations.
We have a history of operating losses. We expect to incur net losses and we may never achieve or maintain profitability.
We have not been profitable since our inception in 1986. We reported net losses of $26.3 million in the fiscal year ended December 31, 2019, $28.8 million in the fiscal year ended December 31, 2018, and $11.7 million in the fiscal year ended December 31, 2017, and as of December 31, 2019, we had an accumulated deficit of $301.9 million.
We have not generated any significant revenue to date and it is possible that we will never have sufficient product sales revenue (if any) to achieve profitability. We expect to continue to incur losses for at least the next several years as we or our collaborators and licensees pursue clinical trials and research and development efforts. To become profitable, we, either alone or with our collaborators and licensees, must successfully develop, manufacture and market our current product candidates APTO-253 or CG-806, as well as continue to identify, develop, manufacture and market new product candidates. It is possible that we will never have significant product sales revenue or receive royalties on our licensed product candidates. If funding is insufficient at any time in the future, we may not be able to develop or commercialize our products, take advantage of business opportunities or respond to competitive pressures.
We currently do not earn any revenues from our drug candidates and are therefore considered to be in the development stage. The continuation of our research and development activities and the commercialization of the targeted therapeutic products are dependent upon our ability to successfully finance and complete our research and development programs through a combination of equity financing and payments from strategic partners. We have no current sources of significant payments from strategic partners.
We heavily rely on the capabilities and experience of our key executives and scientists and the loss of any of them could affect our ability to develop our products.
The loss of our executive officers could harm our operations and our ability to achieve strategic objectives. While we have employment agreements with our executive officers, such employment agreements do not guarantee their retention. We also depend on our scientific and clinical collaborators and advisors, all of whom have outside commitments that may limit their availability to us. In addition, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled scientific, managerial, medical, clinical and regulatory personnel, particularly as we expand our activities and seek regulatory approvals for clinical trials. We routinely enter into consulting agreements with our scientific and clinical collaborators and advisors, key opinion leaders and academic partners in the ordinary course of our business. We also enter into contractual agreements with physicians and institutions who will recruit patients into our clinical trials on our behalf in the ordinary course of our business. Notwithstanding these arrangements, we face significant competition for these types of personnel from other companies, research and academic institutions, government entities and other organizations. We cannot predict our success in hiring or retaining the personnel we require for continued growth. The loss of the services of any of our executive officers or other key personnel could potentially harm our business, operating results or financial condition.
Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our business.
We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include failures to comply with FDA/Health Canada regulations, provide accurate information to the FDA/Health Canada, comply with manufacturing standards we have established, comply with federal, state and provincial health-care fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a substantial impact on our business and results of operations, including the imposition of substantial fines or other sanctions.
We have no sales, marketing or distribution experience and would have to invest significant financial and management resources to establish these capabilities.
We have no sales, marketing or distribution experience. We currently expect to rely heavily on third parties to launch and market our products, if they approved. However, if we elect to develop internal sales, distribution and marketing capabilities, we will need to invest significant financial and management resources. For products where we decide to perform sales, marketing and distribution functions ourselves, we could face a number of additional risks, including:
·we may not be able to attract and build a significant marketing or sales force;
·the cost of establishing a marketing or sales force may not be justifiable in light of the revenues generated by any particular product; and
·our direct sales and marketing efforts may not be successful.
If we are unable to develop our own sales, marketing and distribution capabilities, we will not be able to successfully commercialize our products without reliance on third parties.
We may expand our business through the acquisition of companies or businesses or by entering into collaborations or by in-licensing product candidates, each of which could disrupt our business and harm our financial condition.
We may in the future seek to expand our pipeline and capabilities by acquiring one or more companies or businesses, entering into collaborations or in-licensing one or more product candidates. For example, in June 2016, we entered into a definitive agreement with CG, granting Aptose an exclusive option to research, develop and commercialize CG-806 in all countries of the world except Korea, for all fields of use.
Acquisitions, collaborations and in-licenses involve numerous risks, including, but not limited to:
·substantial cash expenditures;
·technology development risks;
·potentially dilutive issuances of equity securities;
·incurrence of debt and contingent liabilities, some of which may be difficult or impossible to identify at the time of acquisition;
·difficulties in assimilating the operations of the acquired companies;
·potential disputes regarding contingent consideration;
·diverting our management’s attention away from other business concerns;
·entering markets in which we have limited or no direct experience;
·potential loss of our key employees or key employees of the acquired companies or businesses; and
·failure of the in-licenses agents or technologies to deliver the desired activities or functions.
We have experience in entering collaborations and in-licensing product candidates; however, we cannot provide assurance that any acquisition, collaboration or in-license will result in short-term or long-term benefits to us. We may incorrectly judge the value or worth of an acquired company or business or in-licensed product candidate. In addition, our future success would depend in part on our ability to manage the rapid growth associated with some of these acquisitions, collaborations and in-licenses. We cannot assure you that we would be able to successfully combine our business with that of acquired businesses, manage a collaboration or integrate in-licensed product candidates. Furthermore, the development or expansion of our business may require a substantial capital investment by us.
Fluctuations in exchange rates can cause us to incur losses.
We may be exposed to fluctuations of the United States dollar against certain other currencies because we hold most of our cash and cash equivalents in United States dollars, while we incur some of our expenses in foreign currencies, primarily the Canadian dollar. Fluctuations in the value of currencies could cause us to incur currency exchange losses, and we do not currently employ a hedging strategy against exchange rate risk. As a result, changes in the exchange rate between the Canadian dollar and the U.S. dollar could materially impact our reported results of operations and distort period to period comparisons. In particular, to the extent that foreign currency-denominated (i.e., non-U.S. dollar) monetary assets do not equal the amount of our foreign currency denominated monetary liabilities, foreign currency gains or losses could arise and materially impact our financial statements. As a result of such foreign currency fluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent that fluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our investors, the trading price of our Common Shares could be adversely affected.
Risks Related to Development, Clinical Testing and Regulatory Approval of Our Product Candidates
Clinical trials are long, expensive and uncertain processes and the FDA or Health Canada may ultimately not approve any of our product candidates. We may never develop any commercial drugs or other products that generate revenues.
In the past five years, none of our product candidates has received regulatory approval for commercial use and sale in North America. We cannot market a pharmaceutical product in any jurisdiction until it has completed thorough preclinical testing and clinical trials in addition to that jurisdiction’s extensive regulatory approval process. Approval in one country does not assure approval in another country. In general, significant research and development and clinical studies are required to demonstrate the safety and effectiveness of our product candidates before we can submit any applications for regulatory approval.
Clinical trials are long, expensive and uncertain processes. Clinical trials may not start or be on schedule and the FDA or Health Canada or any other regulatory body may not ultimately approve our product candidates for commercial sale in the relevant territory. The clinical trials of any of our drug candidates could be unsuccessful, which would prevent us from advancing, commercializing or partnering the drug.
Even if the results of our preclinical studies or clinical trials are initially positive, it is possible that we will obtain different results in the later stages of drug development or that results seen in clinical trials will not continue with longer term treatment. Positive results in Phase I clinical trials may not necessarily repeat in larger Phase II or Phase III clinical trials.
Our preclinical studies and clinical trials may not generate positive results that will allow us to move towards the commercial use and sale of our product candidates. Furthermore, negative preclinical or clinical trial results may cause our business, financial condition, or results of operations to be materially adversely affected. For example, our Phase Ib clinical trial of APTO-253 in patients with relapsed or refractory AML and high risk MDS was placed on clinical hold by the FDA in November 2015. Those short comings of the drug product were addressed and the clinical hold was lifted. However, there can be no assurance that the Company will have the resources, or that we will decide, to continue the development of APTO-253. There is a long development path ahead that will take many years to complete the development and is prone to the risks of failure or delays inherent in drug development. Likewise, our CG-806 product candidate is currently being evaluated in a Phase Ia/b study for patients having B-cell malignancies, and it is expected to undergo many years of testing and regulatory examinations prior to any potential regulatory approvals.
Preparing, submitting and advancing applications for regulatory approval of products is complex, expensive and time intensive and entails significant uncertainty. A commitment of substantial resources to conduct time-consuming research, preclinical studies and clinical trials is required if we are to complete development of our products.
Clinical trials of our products require that we identify and enroll a large number of patients with the illness under investigation. We may not be able to enroll a sufficient number of appropriate patients to complete our clinical trials in a timely manner, particularly in smaller indications and indications where there is significant competition for patients. If we experience difficulty in enrolling a sufficient number of patients to conduct our clinical trials, we may need to delay or terminate ongoing clinical trials and will not accomplish objectives material to our success. Delays in planned patient enrollment or lower than anticipated event rates in our current clinical trials or future clinical trials also may result in increased costs, program delays, or both.
In addition, unacceptable toxicities or adverse side effects may occur at any time in the course of preclinical studies or human clinical trials or, if any product candidates are successfully developed and approved for marketing, during commercial use of any approved products. The appearance of any unacceptable toxicities or adverse side effects could interrupt, limit, delay or abort the development of any of our product candidates or, if previously approved, necessitate their withdrawal from the market. Furthermore, disease resistance or other unforeseen factors may limit the effectiveness of our potential products.
Our failure to develop safe and commercially viable drugs would substantially impair our ability to generate revenues and sustain our operations and would materially harm our business and adversely affect our share price.
We may not achieve our projected development goals in the time frames we announce and expect.
We set goals for, and make public statements regarding, the expected timing of the accomplishment of objectives material to our success, such as the commencement and completion of clinical trials, the submission of a drug-regulatory application, and the expected costs to develop our product candidates. The actual timing and costs of these events can vary dramatically due to factors within and beyond our control, such as delays or failures in our IND submissions or clinical trials, issues related to the manufacturing of drug supply, uncertainties inherent in the regulatory approval process, market conditions and interest by partners in our product candidates among other things. Our clinical trials may not be completed, we may not make regulatory submissions or receive regulatory approvals as planned; or we may not secure partnerships for any of our product candidates. Any failure to achieve one or more of these milestones as planned would have a material adverse effect on our business, financial condition and results of operations.
Delays in clinical testing could result in delays in commercializing our product candidates and our business may be substantially harmed.
We cannot predict whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, if at all. Our product development costs will increase if we experience delays in clinical testing. Significant clinical trial delays could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before us, which would impair our ability to successfully commercialize our product candidates and may harm our financial condition, results of operations and prospects. The recommencement and completion of clinical trials for our products, including the APTO-253 phase Ib clinical trial, the phase Ia/b clinical trial for CG-806 study for the treatment of patients having B-cell malignancies, and the IND acceptance of our planned Phase I study for the development of CG-806 for the treatment of patients with relapsed/refractory acute myeloid leukemia (“R/R AML”) may be delayed for a number of reasons, including delays related, but not limited, to:.
·failure by regulatory authorities to grant permission to proceed with a clinical trial;
·a regulatory decision to place or placing the clinical trial on hold;
·patients failing to enroll or remain in our trials at the rate we expect;
·suspension or termination of clinical trials by regulators for many reasons, including concerns about patient safety or failure of our contract manufacturers to comply with cGMP requirements;
·any changes to our manufacturing process that may be necessary or desired;
·delays or failure to obtain GMP-grade clinical supply from contract manufacturers of our products necessary to conduct clinical trials;
·product candidates demonstrating a lack of safety or efficacy during clinical trials;
·patients choosing an alternative treatment for the indications for which we are developing any of our product candidates or participating in competing clinical trials;
·patients failing to complete clinical trials due to dissatisfaction with the treatment, side effects or other reasons;
·reports of clinical testing on similar technologies and products raising safety and/or efficacy concerns;
·competing clinical trials and scheduling conflicts with participating clinicians;
·clinical investigators not performing our clinical trials on their anticipated schedule, dropping out of a trial, or employing methods not consistent with the clinical trial protocol, regulatory requirements or other third parties not performing data collection and analysis in a timely or accurate manner;
·failure of our contract research organizations, or CROs, to satisfy their contractual duties or meet expected deadlines;
·inspections of clinical trial sites by regulatory authorities or IRBs, or ethics committees or boards finding regulatory violations that require us to undertake corrective action, resulting in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study;
·one or more IRBs or ethics committees or boards rejecting, suspending or terminating the study at an investigational site, precluding enrollment of additional subjects, or withdrawing its approval of the trial; or
·failure to reach agreement on acceptable terms with prospective clinical trial sites.
Our product development costs will increase if we experience delays in testing or approval or if we need to perform more or larger clinical trials than planned. Additionally, changes in regulatory requirements and policies may occur, and we may need to amend study protocols to reflect these changes. Amendments may require us to resubmit our study protocols to regulatory authorities or IRBs or ethics committees or boards for re-examination, which may impact the cost, timing or successful completion of a trial. Delays or increased product development costs may have a material adverse effect on our business, financial condition and prospects.
We rely on contract manufacturers over whom we have limited control. If we are subject to quality, cost or delivery issues with the preclinical and clinical grade materials supplied by contract manufacturers, our business operations could suffer significant harm.
We rely on CMOs to manufacture our product candidates for some preclinical studies and clinical trials. We rely on CMOs for manufacturing, filling, packaging, storing and shipping of drug product in compliance with cGMP regulations applicable to our products. The FDA and other regulatory agencies ensure the quality of drug products by carefully monitoring drug manufacturers’ compliance with cGMP regulations. The cGMP regulations for drugs contain minimum requirements for the methods, facilities and controls used in manufacturing, processing and packing of a drug product.
We contracted with multiple CMOs for the manufacture of APTO-253 and CG-806 to supply the active ingredient and then drug product for our clinical trials. The synthesis of CG-806 is challenging from a scale-up synthetic chemistry perspective. The formulation and manufacture of APTO-253 is a complex process with many variables involved. We pre-qualified CMOs to have the capacity, the systems and the experience to supply CG-806 and APTO-253 for our clinical trials. We have qualified the manufacturing facilities and the FDA has also performed site audits for our selected CMOs. In spite of the efforts to prequalify CMOs, delays and errors may occur, and any such manufacturing failures, delays or compliance issues could cause delays in the completion of our clinical trial programs.
There can be no assurances that CMOs will be able to meet our timetable and requirements. We have contracted with alternate suppliers in the event our current CMOs are unable to scale up production, or if our current CMOs otherwise experience any other significant problems in the manufacture of CG-806 and APTO-253. However, it is possible that all third-party manufacturing sources may experience failure or delays and may demand commercially unreasonable terms, which may lead to further delays in the development of our product candidates. Further, contract manufacturers must operate in compliance with cGMP and failure to do so could result in, among other things, the disruption of product supplies. Our dependence upon third parties for the manufacture of our products may adversely affect our profit margins and our ability to develop and deliver products on a timely and competitive basis.
Some components of our products are manufactured by third parties outside of the United States, and our business may be harmed by legal, regulatory, economic, political and public health risks associated with international trade and those markets.
We have third-party manufacturing partners in Germany and the United Kingdom; in addition, some materials used by our third-party manufacturers are supplied by companies located in other countries, including China. Our reliance on suppliers and manufacturers in foreign markets creates risks inherent in doing business in foreign jurisdictions, including: (a) the burdens of complying with a variety of foreign laws and regulations, including laws relating to the importation and taxation of goods (b) public health crises, such as pandemics and epidemics, in the countries where our suppliers and manufacturers are located; (c) transportation interruptions or increases in transportation costs; and (d) foreign intellectual property infringement risks. For example, the ongoing coronavirus outbreak emanating from China at the beginning of 2020 has resulted in extended shutdown of certain businesses in the region causing reduced availability for certain pharmaceutical ingredients. This public health crisis or any further political developments or health concerns in markets in which our products are manufactured or from which we obtain necessary pharmaceutical ingredients could adversely affect the supply of our drug products and, in turn, our business, financial condition, and results of operations.
If we have difficulty enrolling patients in clinical trials, the completion of the trials may be delayed or cancelled.
As our product candidates advance from preclinical testing to clinical testing, and then through progressively larger and more complex clinical trials, we will need to enroll an increasing number of patients that meet our eligibility criteria. There is significant competition for recruiting cancer patients in clinical trials, and we may be unable to enroll the patients we need to complete clinical trials for cancer indications on a timely basis or at all. Certain factors that affect enrollment of patients in our clinical trials are impacted by external forces that may be beyond our control. Such factors include, but are not limited to, the following:
·size and nature of the patient population;
·eligibility and exclusion criteria for the trial;
·design of the study protocol;
·competition with other companies for clinical sites or patients;
·the perceived risks and benefits of the product candidate under study;
·the patient referral practices of physicians; and
·the number, availability, location and accessibility of clinical trial sites.
If we are unable to successfully develop companion diagnostics for our therapeutic product candidates, or experience significant delays in doing so, we may not achieve marketing approval or realize the full commercial potential of our therapeutic product candidates.
We plan to develop companion diagnostics for our therapeutic product candidates. We expect that, at least in some cases, regulatory authorities may require the development and regulatory approval of a companion diagnostic as a condition to approving our therapeutic product candidates. We have limited experience and capabilities in developing or commercializing diagnostics and plan to rely in large part on third parties to perform these functions. We do not currently have any agreement in place with any third party to develop or commercialize companion diagnostics for any of our therapeutic product candidates.
Companion diagnostics are subject to regulation by the FDA, Health Canada and comparable foreign regulatory authorities as medical devices and may require separate regulatory approval or clearance prior to commercialization. If we, or any third parties that we engage to assist us, are unable to successfully develop companion diagnostics for our therapeutic product candidates, or experience delays in doing so, our business may be substantially harmed.
We rely and will continue to rely on third parties to conduct and monitor many of our preclinical studies and our clinical trials, and their failure to perform as required could cause substantial harm to our business.
We rely and will continue to rely on third parties to conduct a significant portion of our preclinical and clinical development activities. Preclinical activities include in vivo studies providing access to specific disease models, pharmacology and toxicology studies, and assay development. Clinical development activities include trial design, regulatory submissions, clinical patient recruitment, clinical trial monitoring, clinical data management and analysis, safety monitoring and project management, contract manufacturing and quality assurance. If there is any dispute or disruption in our relationship with third parties, or if they are unable to provide quality services in a timely manner and at a feasible cost, our active development programs will face delays. Further, if any of these third parties fails to perform as we expect or if their work fails to meet regulatory requirements, our testing could be delayed, cancelled or rendered ineffective.
Negative results from clinical trials or studies of others and adverse safety events involving the targets of our products may have an adverse impact on our future commercialization efforts.
From time to time, studies or clinical trials on various aspects of biopharmaceutical products are conducted by academic researchers, competitors or others. The results of these studies or trials, when published, may have a significant effect on the market for the biopharmaceutical product that is the subject of the study. The publication of negative results of studies or clinical trials or adverse safety events related to our product candidates, or the therapeutic areas in which our product candidates compete, could adversely affect our share price and our ability to finance future development of our product candidates, and our business and financial results could be materially and adversely affected.
The design or our execution of clinical trials may not support regulatory approval.
The design or execution of a clinical trial can determine whether its results will support regulatory approval and flaws in the design or execution of a clinical trial may not become apparent until the clinical trial is well advanced. In some instances, there can be significant variability in safety or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. We do not know whether any Phase II, Phase III or other clinical trials that we may conduct will demonstrate consistent or adequate efficacy and safety to obtain regulatory approval to market our product candidates.
Further, the FDA, Health Canada and comparable foreign regulatory authorities will have some discretion in the approval process and in determining when or whether regulatory approval will be obtained for any of our product candidates. Our product candidates may not be approved even if they achieve their primary endpoints in future Phase III clinical trials or registration trials. The FDA, Health Canada or other regulatory authorities may disagree with our trial design and the Company’s interpretation of data from preclinical studies and clinical trials. In addition, any of these regulatory authorities may change requirements for the approval of a product candidate even after reviewing and providing comments or advice on a protocol for a pivotal Phase III clinical trial that has the potential to result in approval by the FDA, Health Canada or another regulatory agency. In addition, any of these regulatory authorities may also approve a product candidate for fewer or more limited indications than the Company requests or may grant approval contingent on the performance of costly post-marketing clinical trials. The FDA, Health Canada or other regulatory authorities may not approve the labeling claims that we believe would be necessary or desirable for the successful commercialization of our product candidates.
As a result of intense competition and technological change in the biotechnical and pharmaceutical industries, the marketplace may not accept our products or product candidates, and we may not be able to compete successfully against other companies in our industry and achieve profitability.
Many of our competitors have:
·drug products that have already been approved or are in development;
·large, well-funded research and development programs in the biotechnical and pharmaceutical fields;large, well-funded research and development programs in the biotechnical and pharmaceutical fields;
·substantially greater financial, technical and management resources, stronger intellectual property positions and greater manufacturing, marketing and sales capabilities, areas in which we have limited or no experience; and
·significantly greater experience than we do in undertaking preclinical testing and clinical trials of new or improved pharmaceutical products and obtaining required regulatory approvals.
Consequently, our competitors may obtain FDA, Health Canada and other regulatory approvals for product candidates sooner and may be more successful in manufacturing and marketing their products than we or our collaborators are.
Our competitors’ existing and future products, therapies and technological approaches will compete directly with the products we seek to develop. Current and prospective competing products may be more effective than our existing and future products insofar as they may provide greater therapeutic benefits for a specific problem or may offer easier delivery or comparable performance at a lower cost.
For CG-806 and APTO-253 in AML, examples of potential competitors include Companies that have developed approved or are currently developing inhibitors that directly target the wild type include AbbVie (IMBRUVICA) and AstraZeneca (CALQUENCE) and Beigene Co., Ltd. (Zanubrutinib).
Others that are developing inhibitors that target the C481S-mutant BTK include Arqule, Inc. (ARQ 531), Roche, Sunesis Pharmaceuticals (SNS-062) and Eli Lilly among others.
For CG-806 and APTO-253 in AML, examples of potential competitors include companies that have developed approved or are currently developing non-targeted therapies include Jazz (VYXEOS), Pfizer (MYLOTARG) and Roche (VENCLEXTA), among others. Others that have developed or are developing highly targeted therapies such as FLT-3 include Novartis (RYDAPT), Astellas (XOSAPTA), Daiichi Sankyo (QUIZARTINIB), Arog (CRENOLANIB), and IDH1 include Agios (TIBSOVO) and Celgene/BMS (IDHIFA) among others.
Any product candidate that we develop and that obtains regulatory approval must then compete for market acceptance and market share. Our products may not gain market acceptance among physicians, patients, healthcare payers, insurers, the medical community and other stakeholders. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including:
·efficacy and potential advantages compared to alternative treatments;
·the ability to offer our product candidates for sale at competitive prices;
·convenience and ease of administration compared to alternative treatments;
·the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;
·the strength of marketing and distribution support;
·sufficient third-party coverage or reimbursement; and
·the prevalence and severity of any side effects.
Further, any products we develop may become obsolete or face generic entry before we recover any expenses we incurred in connection with the development of these products. As a result, we may never achieve profitability.
Risks Related to our Intellectual Property
We may be unable to obtain patents to protect our technologies from other companies with competitive products, and patents of other companies could prevent us from manufacturing, developing or marketing our products.
Patent protection
The patent positions of pharmaceutical and biotechnology companies are uncertain and involve complex legal and factual questions. The USPTO and many other patent offices in the world have not established a consistent policy regarding the breadth of claims that they will allow in biotechnology patents.
Our pending patent applications may not result in issued patents and our issued patents may not be held valid and enforceable if challenged. Competitors may be able to circumvent any such issued patents by adoption of a competitive, though non-infringing product or process. Interpretation and evaluation of pharmaceutical or biotechnology patent claims present complex and often novel legal and factual questions. Our business could be adversely affected by increased competition in the event that any patent granted to it is held to be invalid or unenforceable or is inadequate in scope to protect our operations.
Allowable patentable subject matter and the scope of patent protection obtainable may differ between jurisdictions. If a patent office allows broad claims, the number and cost of patent interference proceedings in the United States, or analogous proceedings in other jurisdictions and the risk of infringement litigation may increase. If it allows narrow claims, the risk of infringement may decrease, but the value of our rights under our patents, licenses and patent applications may also decrease.
The scope of the claims in a patent application can be significantly modified during prosecution before the patent is issued. Consequently, we cannot know whether our pending applications will result in the issuance of patents or, if any patents are issued, whether they will provide us with significant proprietary protection or will be circumvented, invalidated or found to be unenforceable.
Publication of discoveries in scientific or patent literature often lags behind actual discoveries. Patent applications filed in the United States generally will be published 18 months after the filing date unless the applicant certifies that the invention will not be the subject of a foreign patent application. In many other jurisdictions, such as Canada, patent applications are published 18 months from the priority date. We may not be aware of such literature. Accordingly, we cannot be certain that the named inventors of our products and processes were the first to invent that product or process or that we were the first to pursue patent coverage for our inventions.
In addition, United States patent laws may change which could prevent or limit us from filing patent applications or patent claims in the United States to protect our products and technologies or limit the exclusivity periods that are available to patent holders for United States patents. For example, the Leahy-Smith America Invents Act, (the “Leahy-Smith Act”) was signed into law in 2011 and includes a number of significant changes to United States patent law. These include changes to transition from a “first-to-invent” system to a “first-to-file” system and to the way issued patents are challenged. These changes may favor larger and more established companies that have more resources to devote to patent application filing and prosecution. It is not clear what, if any, impact the Leahy-Smith Act will ultimately have on the cost of prosecuting our patent applications in the United States, our ability to obtain patents in the United States based on our discoveries and our ability to enforce or defend our United States issued patents.
Until such time, if ever, that further patents are issued to us, we will rely upon the law of trade secrets to the extent possible given the publication requirements under international patent treaty laws and/or requirements under foreign patent laws to protect our technology and our products incorporating the technology. In this regard, we have adopted certain confidentiality procedures. These include: limiting access to confidential information to certain key personnel; requiring all directors, officers, employees and consultants and others who may have access to our intellectual property to enter into confidentiality agreements which prohibit the use of or disclosure of confidential information to third parties; and implementing physical security measures designed to restrict access to such confidential information and products. Our ability to maintain the confidentiality of our technology is crucial to our ultimate possible commercial success. The procedures adopted by us to protect the confidentiality of our technology may not be effective, third parties may gain access to our trade secrets or our trade secrets or those of our collaborators may be independently discovered by others. Our collaborators, employees and consultants and other parties may not comply with the terms of their agreements with us, and we might be unable to adequately enforce our rights or obtain adequate compensation for the damages caused by unauthorized disclosure or use of our trade secrets or know how. Further, by seeking patent protection in various countries, it is inevitable that a substantial portion of our technology will become available to our competitors, through publication of such patent applications.
Enforcement of intellectual property rights
Protection of the rights revealed in published patent applications can be complex, costly and uncertain. Our commercial success depends in part on our ability to maintain and enforce our proprietary rights. If third parties engage in activities that infringe our proprietary rights, our management’s focus will be diverted and we may incur significant costs in asserting our rights. We may not be successful in asserting our proprietary rights, which could result in our patents being held invalid or a court holding that the third party is not infringing, either of which would harm our competitive position.
Others may design around our patented technology. We may have to participate in interference proceedings declared by the United States Patent and Trademark Office, European opposition proceedings, or other analogous proceedings in other parts of the world to determine priority of invention and the validity of patent rights granted or applied for, which could result in substantial cost and delay, even if the eventual outcome is favorable to us. Our pending patent applications, even if issued, may not be held valid or enforceable.
Our products and product candidates may infringe the intellectual property rights of others, or others may infringe on our intellectual property rights which could increase our costs.
Our success also depends on avoiding infringement of the proprietary technologies of others. In particular, there may be certain issued patents and patent applications claiming subject matter which we or our collaborators may be required to license in order to research, develop or commercialize APTO-253 or CG-806. In addition, third parties may assert infringement or other intellectual property claims against us. An adverse outcome in these proceedings could subject us to significant liabilities to third-parties, require disputed rights to be licensed from third-parties or require us to cease or modify our use of the technology. If we are required to license third-party technology, a license under such patents and patent applications may not be available on acceptable terms or at all. Further, we may incur substantial costs defending ourselves in lawsuits against charges of patent infringement or other unlawful use of another’s proprietary technology. We may also need to bring claims against others who we believe are infringing our rights in order to become or remain competitive and successful. Any such claims can be time consuming and expensive to pursue.
We may incur substantial cost in defending our intellectual property.
While we believe that our products and technology do not infringe proprietary rights of others, third parties may assert infringement claims in the future and such claims could be successful. Even if challenges are unsuccessful, we could incur substantial costs in defending ourselves against patent infringement claims brought by others or in prosecuting suits against others. In addition, others may obtain patents that we would need to license, which may not be available to us on reasonable terms. Whether we are able to obtain a necessary license would depend on the terms offered, the degree of risk of infringement and the need for the patent.
We have licensed important portions of our intellectual property from CG, and are subject to significant obligations under that license agreement.
The rights we hold under our license agreement with CG are critical to our business. Our CG-806 program is built around patents exclusively in-licensed from CG, which permit us to research, develop and commercialize CG-806 worldwide except for the Republic of Korea. Under our agreement with CG, we are subject to significant obligations, including diligence obligations with respect to development and commercialization activities, payment obligations upon achievement of certain milestones and royalties on product sales, as well as other material obligations. CG is eligible for payments upon the achievement of developmental, regulatory and commercial-based milestones, as well as low single-digit royalties on product sales in all territories outside of the Republic of Korea.
If there is any conflict, dispute, disagreement or issue of non-performance between us and CG regarding our rights or obligations under the license agreements, including any conflict, dispute or disagreement arising from our failure to satisfy diligence or payment obligations under such agreements, CG may have a right to terminate the license. The loss of this license agreement could materially and adversely affect our ability to use intellectual property that could be critical to our drug discovery and development efforts, as well as our ability to enter into future collaboration, licensing and/or marketing agreements for one or more affected drug candidates or development programs.
Our business depends, in part, on our ability to use technology that we have licensed or will in the future license from third parties, including CG, and, if these licenses were terminated or if we were unable to license additional technology we may need in the future, our business will be adversely affected.
We currently hold licenses for certain technologies that are or may be critical to our current and subsequent product candidates. These include our exclusive license to research, develop and commercialize CG-806 worldwide except for the Republic of Korea. The license from CG is subject to termination in the event of a breach by us of the license, if we fail to cure the breach following notice and the passage of a cure period. We may need to acquire additional licenses in the future to technologies developed by others. Furthermore, future license agreements may require us to make substantial milestone payments. We may also be obligated to make royalty payments on the sales, if any, of products resulting from the license. The termination of a license or the inability to license future technologies on acceptable terms may adversely affect our ability to develop or sell our products.
Legal and Regulatory Risk
Our ability to develop, produce and market our products is subject to extensive government regulation.
Government regulation is a significant factor in the development, production and marketing of the Company’s products. Research and development, testing, manufacture, marketing and sales of pharmaceutical products or related products are subject to extensive regulatory oversight, often in multiple jurisdictions, which may cause significant additional costs and/or delays in bringing products to market, and in turn, may cause significant losses to investors. The regulations applicable to the Company’s product candidates in a given jurisdiction may change. Even if granted, regulatory approvals may include significant limitations on the uses for which products can be marketed or may be conditioned on the conduct of post-marketing surveillance studies. Failure to comply with applicable regulatory requirements can, among other things, result in delay in approving or refusal to approve a product candidate, interruptions of clinical trials or manufacturing, suspension or withdrawal of regulatory approval, warning letters, the imposition of civil penalties or other monetary payments, product recall or seizure, operating restrictions, injunctions or criminal prosecution. In addition, regulatory agencies many not approve the labeling claims that are necessary or desirable for the successful commercialization of the Company’s product candidates.
Requirements for regulatory approval vary widely from country to country. Whether or not approved in Canada or the United States, regulatory authorities in other countries must approve a product prior to the commencement of marketing the product in those countries. The time required to obtain any such approval may be longer or shorter than in Canada or the United States. Approved drugs, as well as their manufacturers, are subject to continuing and ongoing review, and discovery of problems with these products or the failure to adhere to manufacturing or quality control requirements may result in regulatory restrictions being imposed.
Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and may adversely affect the prices we may obtain.
In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our product candidates, restrict or regulate post approval activities and affect our ability to profitably sell any products for which we obtain marketing approval.
For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care Education Reconciliation Act, or collectively the Affordable Care Act, was enacted to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for health care and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Additionally, the Drug Supply Chain Security Act, enacted in 2013, imposed new obligations on manufacturers of pharmaceutical products related to product tracking and tracing.
Members of Congress and the Trump Administration have considered legislation to fundamentally change or repeal the Affordable Care Act. While Congress has not passed repeal legislation to date, the Tax Cuts and Jobs Act (“TCJA”) includes a provision repealing the individual insurance coverage mandate included in the Affordable Care Act, effective January 1, 2019. Further, President Trump signed an Executive Order directing federal agencies with authorities and responsibilities under the Affordable Care Act to waive, defer, grant exemptions from, or delay the implementation of any provision of the Affordable Care Act that would impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. On October 13, 2017, the President signed an Executive Order terminating the cost-sharing subsidies that reimburse insurers under the Affordable Care Act. Several state Attorneys General filed suit to stop the administration from terminating the subsidies, but their request for a restraining order was denied by a federal judge in California on October 25, 2017. In addition, the Centers for Medicare and Medicaid Services has recently proposed regulations that would give states greater flexibility in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits required under the Affordable Care Act for plans sold through such marketplaces. Congress may consider other legislation to replace elements of the Affordable Care Act. The implications of the Affordable Care Act, its possible repeal, any legislation that may be proposed to replace the Affordable Care Act, or the political uncertainty surrounding any repeal or replacement legislation for our business and financial condition, if any, are not yet clear.
We expect ongoing initiatives in the United States and internationally to increase pressure on drug pricing. Regulations that mandate price controls and limitations on patient access to products or establish prices paid by government entities or programs may impact product candidates that we may successfully develop. Pharmaceutical product pricing is subject to enhanced government and public scrutiny and calls for reform. Some U.S. states have implemented, and other U.S. states are considering, pharmaceutical price controls or patient access constraints under the Medicaid program, and some U.S. states are considering price-control regimes that would apply to broader segments of their populations that are not Medicaid eligible. Efforts by government officials or legislators to implement measures to regulate prices or payments for pharmaceutical products, including legislation on drug importation, could have an adverse effect on anticipated revenues from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop drug candidates.
Legislative and regulatory proposals have also been made to expand post approval requirements and restrict sales and promotional activities for pharmaceutical products in the US. Any healthcare reforms enacted in the future may, like the Affordable Care Act, be phased in over a number of years but, if enacted, could reduce our revenue, increase our costs, or require us to revise the ways in which we conduct business or put us at risk for loss of business. We are not sure whether additional legislative changes will be enacted, or whether the current regulations, guidance or interpretations will be changed, or what the impact of such changes on our business, if any, may be.
In Canada, the Patented Medicine Prices Review Board ("PMPRB") has jurisdiction to control prices of patented medicines that are considered excessive. Recent changes to the regulations governing the PMPRB are intended to lower the prices of patented medicines even further. The PMPRB's jurisdiction could extend to any of our drug products that are approved in Canada and protected under Canadian patents, with an adverse effect on the prices that we would otherwise obtain for these drugs in the relevant market.
Coverage and adequate reimbursement may not be available for our product candidates, which could make it difficult for us to sell our products profitably.
Market acceptance and sales of any drug candidates that we develop will depend in part on the extent to which reimbursement for these products and related treatments will be available from third party payors, including government health administration authorities and private health insurers. Third party payors decide which drugs they will pay for and establish reimbursement levels. Third party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for each of our drug candidates will be made on a plan by plan basis. One payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product. Additionally, a third party payor’s decision to provide coverage for a drug does not imply that an adequate reimbursement rate will be approved. Each plan determines whether or not it will provide coverage for a drug, what amount it will pay the manufacturer for the drug, and on what tier of its formulary the drug will be placed. The position of a drug on a formulary generally determines the copayment that a patient will need to make to obtain the drug and can strongly influence the adoption of a drug by patients and physicians. Patients who are prescribed treatments for their conditions and providers performing the prescribed services generally rely on third party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products.
A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Third party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval. If coverage and adequate reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize any drug candidates that we develop.
Additionally, there have been a number of legislative and regulatory proposals to change the healthcare system in the United States and in some foreign jurisdictions, including Canada, that could affect our ability to sell any future drugs profitably. These legislative and regulatory changes may negatively impact the reimbursement for any future drugs, following approval.
We are subject to U.S. and Canadian healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, fines, disgorgement, exclusion from participation in government healthcare programs, curtailment or restricting of our operations and diminished profits and future earnings.
Healthcare providers, physicians and others will play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. Our future arrangements with healthcare providers, patients and third party payors could expose us to broadly applicable U.S. and Canadian laws and regulations relating to fraud abuse and healthcare more generally that may constrain the business or financial arrangements and collaborative partners through which we market, sell and distribute any products for which we obtain marketing approval.
Efforts to ensure that our collaborations with third parties, and our business generally, will comply with applicable U.S. and Canadian healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental laws and regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion of products from government funded healthcare programs, contractual damages, reputational harm, disgorgement, curtailment or restricting of our operations, any of which could substantially disrupt our operations and diminish our profits and future earnings. If any of the physicians or other providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations.
If product liability, clinical trial liability or environmental liability claims are brought against us or we are unable to obtain or maintain product liability, clinical trial or environmental liability insurance, we may incur substantial liabilities that could reduce our financial resources.
The clinical testing and commercial use of pharmaceutical products involves significant exposure to product liability, clinical trial liability, environmental liability and other risks that are inherent in the testing, manufacturing and marketing of our products. These liabilities, if realized, could have a material adverse effect on the Company’s business, results of operations and financial condition.
We have obtained limited product liability insurance coverage for our clinical trials on humans; however, our insurance coverage may be insufficient to protect us against all product liability damages. Regardless of merit or eventual outcome, liability claims may result in decreased demand for a future product, injury to reputation, withdrawal of clinical trial volunteers, loss of revenue, costs of litigation, distraction of management and substantial monetary awards to plaintiffs. Additionally, if we are required to pay a product liability claim, we may not have sufficient financial resources to complete development or commercialization of any of our product candidates and our business and results of operations will be adversely affected. In general, insurance will not protect us against some of our own actions, such as negligence.
As the Company’s development activities progress towards the commercialization of product candidates, our liability coverage may not be adequate, and the Company may not be able to obtain adequate product liability insurance coverage at a reasonable cost, if at all. Even if the Company obtains product liability insurance, its financial position may be materially adversely affected by a product liability claim. A product liability claim could also significantly harm the Company’s reputation and delay market acceptance of its product candidates. Additionally, product recalls may be issued at the direction of the FDA, other government agencies or other companies having regulatory control for pharmaceutical sales. If a product recall occurs in the future, such a recall could adversely affect our business, financial condition or reputation.
If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and radioactive and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.
Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.
In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.
We may be unable to obtain partnerships for our product candidates, which could curtail future development and negatively affect our share price. In addition, our partners might not satisfy their contractual responsibilities or devote sufficient resources to our partnership.
Our strategy for the research, development and commercialization of our products requires entering into various arrangements with corporate collaborators, licensors, licensees and others, and our commercial success is dependent upon these outside parties performing their respective contractual responsibilities. The amount and timing of resources that such third parties will devote to these activities may not be within our control. These third parties may not perform their obligations as expected and our collaborators may not devote adequate resources to our programs. In addition, we could become involved in disputes with our collaborators, which could result in a delay or termination of the related development programs or result in litigation. We intend to seek additional collaborative arrangements to develop and commercialize some of our products. We may not be able to negotiate collaborative arrangements on favorable terms, or at all, in the future, and our current or future collaborative arrangements may not be successful.
If we cannot negotiate collaboration, license or partnering agreements, we may never achieve profitability and we may not be able to continue to develop our product candidates. Commencing Phase I, Phase II and Phase III clinical trials for CG-806 and continuing Phase Ib, and commencing Phase II and Phase III clinical trials for APTO-253 would require significant amounts of funding and such funding may not be available to us.
Risks Related to Our Common Shares
Our share price has been and is likely to continue to be volatile and an investment in our Common Shares could suffer a decline in value.
You should consider an investment in our Common Shares as risky and invest only if you can withstand a significant loss and wide fluctuations in the market value of your investment. The market price of our Common Shares has been highly volatile and is likely to continue to be volatile. This leads to a heightened risk of securities litigation pertaining to such volatility. Factors affecting our Common Share price include but are not limited to:
·the progress of our pre-clinical and clinical trials;
·our ability to obtain partners and collaborators to assist with the future development of our products;
·general market conditions;
·announcements of technological innovations or new product candidates by us, our collaborators or our competitors;
·published reports by securities analysts;
·developments in patent or other intellectual property rights;
·the cash and investments held by us and our ability to secure future financing;
·our ability to raise additional capital;
·public concern as to the safety and efficacy of drugs that we and our competitors develop;
·shareholder interest in our Common Shares;
·low liquidity in the daily trading volume of our Common Shares; and
·our ability to continue as a going concern;
Future sales of our Common Shares by us or by our existing shareholders could cause our share price to fall.
The issuance of Common Shares by us could result in significant dilution in the equity interest of existing shareholders and adversely affect the market price of our Common Shares. Sales by existing shareholders of a large number of our Common Shares in the public market and the issuance of Common Shares in connection with strategic alliances, or the perception that such additional sales could occur, could cause the market price of our Common Shares to decline and have an undesirable impact on our ability to raise capital.
We are susceptible to stress in the global economy and therefore, our business may be affected by the current and future global financial conditions.
If the increased level of volatility and market turmoil that have marked recent years continue, our operations, business, financial condition and the trading price of our Common Shares could be materially adversely affected. Furthermore, general economic conditions may have a great impact on us, including our ability to raise capital, our commercialization opportunities and our ability to establish and maintain arrangements with others for research, manufacturing, product development and sales.
An active trading market in our Common Shares may not be sustained.
Our Common Shares are listed for trading on the Nasdaq Capital Market and the TSX. However, an active trading market in our Common Shares on the stock exchanges may not be sustained and we may not be able to maintain our listings.
Certain Canadian laws could delay or deter a change of control.
Limitations on the ability to acquire and hold our Common Shares may be imposed by the Competition Act in Canada. This legislation permits the Commissioner of Competition of Canada to review any acquisition of a significant interest in us. This legislation grants the Commissioner jurisdiction to challenge such an acquisition before the Canadian Competition Tribunal if the Commissioner believes that it would, or would be likely to, result in a substantial lessening or prevention of competition in any market in Canada. The Investment Canada Act subjects an acquisition of control of a company by a non-Canadian to government review if the value of our assets, as calculated pursuant to the legislation, exceeds a threshold amount. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to result in a net benefit to Canada. Any of the foregoing could prevent or delay a change of control and may deprive or limit strategic opportunities for our shareholders to sell their shares.
The exercise of all or any number of outstanding stock options, the award of any additional options, restricted stock units or other stock-based awards or any issuance of shares to raise funds or acquire a business may dilute your Common Shares.
We have in the past and may in the future grant to some or all of our directors, officers and employees options to purchase our Common Shares and other stock-based awards as non-cash incentives to those persons. The issuance of any equity securities could, and the issuance of any additional shares will, cause our existing shareholders to experience dilution of their ownership interests.
Any additional issuance of shares or a decision to acquire other businesses through the sale of equity securities may dilute our investors’ interests, and investors may suffer dilution in their net book value per share depending on the price at which such securities are sold. Such issuance may cause a reduction in the proportionate ownership and voting power of all other shareholders. The dilution may result in a decline in the price of our Common Shares or a change in control.
We do not expect to pay dividends for the foreseeable future.
We have not paid any cash dividends to date and we do not intend to declare dividends for the foreseeable future, as we anticipate that we will reinvest future earnings, if any, in the development and growth of our business. Therefore, investors will not receive any funds unless they sell their Common Shares, and shareholders may be unable to sell their shares on favorable terms or at all. We cannot assure you of a positive return on investment or that you will not lose the entire amount of your investment in our Common Shares. Prospective investors seeking or needing dividend income or liquidity should not purchase our Common Shares.
Other Risks
It may be difficult for non-Canadian investors to obtain and enforce judgments against us because of our Canadian incorporation and presence.
We are a corporation existing under the laws of Canada. Some of our directors and officers, and many of the experts named in this Annual Report on Form 10-K, are residents of Canada, and all or a substantial portion of their assets, and a substantial portion of our assets, are located outside the United States. Consequently, although we have appointed an agent for service of process in the United States, it may be difficult for holders of our shares who reside in the United States to effect service within the United States upon our directors and officers and experts who are not residents of the United States. It may also be difficult for holders of our shares who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors, officers and experts under the United States federal securities laws. Investors should not assume that Canadian courts (i) would enforce judgments of United States courts obtained in actions against us or our directors, officers or experts predicated upon the civil liability provisions of the United States federal securities laws or the securities or “blue sky” laws of any state within the United States or (ii) would enforce, in original actions, liabilities against us or our directors, officers or experts predicated upon the United States federal securities laws or any such state securities or “blue sky” laws. In addition, we have been advised by our Canadian counsel that in normal circumstances, only civil judgments and not other rights arising from United States securities legislation are enforceable in Canada and that the protections afforded by Canadian securities laws may not be available to investors in the United States.
We are likely a “passive foreign investment company” which may have adverse United States federal income tax consequences for United States shareholders.
United States investors in our Common Shares should be aware that the Company believes it was classified as a passive foreign investment company (“PFIC”) during the tax year ended December 31, 2019, and based on the nature of our business, the projected composition of our gross income and the projected composition and estimated fair market value of our assets, the Company expects to be a PFIC for the year ending December 31, 2020, and may be a PFIC in subsequent tax years. If the Company is a PFIC for any year during a United States shareholder’s holding period, then such United States shareholder generally will be required to treat any gain realized upon a disposition of Common Shares, or any so-called “excess distribution” received on its Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distributions, unless the shareholder makes a timely and effective “qualified electing fund” election (“QEF election”) or a “mark-to-market” election with respect to the Common Shares. A United States shareholder who makes a QEF election generally must report on a current basis its share of the Company’s net capital gain and ordinary earnings for any year in which the Company is a PFIC, whether or not the Company distributes any amounts to its shareholders. However, United States shareholders should be aware that we do not intend to satisfy record keeping requirements that apply to a qualified electing fund, and we do not intend to supply United States shareholders with information that such United States shareholders require to report under the QEF election rules, in the event that we are a PFIC and a United States shareholder wishes to make a QEF election. Thus, United States shareholders should assume that they will not be able to make a QEF election with respect to their Common Shares. A United States shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer’s basis therein. Each United States shareholder should consult its own tax advisor regarding the United States federal, United States local, and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of our Common Shares.
We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our Common Shares less attractive to investors.
We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (United States), or the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (United States) (the “SOX”), reduced disclosure obligations regarding executive compensation in our periodic reports and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.
We will cease to be an emerging growth company upon the earliest of:
·the last day of the fiscal year during which we have total annual gross revenues of $1,000,000,000 (as such amount is indexed for inflation every five years by the SEC or more;
·the last day of our fiscal year following the fifth anniversary of the completion of our first sale of common equity securities pursuant to an effective registration statement under the Securities Act (United States) which will be in September 2020;
·the date on which we have, during the previous three-year period, issued more than $1,000,000,000 in non- convertible debt; or
·the date on which we are deemed to be a “large accelerated filer”, as defined in Rule 12b-2 of the Exchange Act (United States) (the “Exchange Act”), which would occur if the market value of our ordinary shares that are held by non-affiliates exceeds $700,000,000 as of the last day of our most recently completed second fiscal quarter.
We cannot predict if investors will find our Common Shares less attractive because we may rely on these exemptions. If some investors find our Common Shares less attractive as a result, there may be a less active trading market for our Common Shares and our share price may be more volatile.
Any failure to maintain an effective system of internal controls may result in material misstatements of our consolidated financial statements or cause us to fail to meet our reporting obligations or fail to prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would harm our business and could negatively impact the price of our Common Shares.
Section 404(a) of the SOX requires that our management assess and report annually on the effectiveness of our internal control over financial reporting and identify any material weaknesses in our internal control over financial reporting. Although Section 404(b) of the SOX requires our independent registered public accounting firm to issue an annual report that addresses the effectiveness of our internal control over financial reporting, we have opted to rely on the exemptions provided to us by virtue of being an emerging growth company, and consequently will not be required to comply with SEC rules that implement Section 404(b) of SOX until we lose our emerging growth company status.
Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. If we fail to maintain an effective system of internal controls, we might not be able to report our financial results accurately or prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would harm our business and could negatively impact the price of our Common Shares. While we believe that we have sufficient personnel and review procedures to allow us to maintain an effective system of internal controls, we cannot assure you that we will not experience potential material weaknesses in our internal control. Even if we conclude that our internal control over financial reporting provides reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles in the United States (“US GAAP”), because of its inherent limitations, internal control over financial reporting may not prevent or detect fraud or misstatements. Failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our results of operations or cause us to fail to meet our future reporting obligations.
If we fail to timely achieve and maintain the adequacy of our internal control over financial reporting, we may not be able to produce reliable financial reports or help prevent fraud. Our failure to achieve and maintain effective internal control over financial reporting could prevent us from complying with our reporting obligations on a timely basis, which could result in the loss of investor confidence in the reliability of our consolidated financial statements, harm our business and negatively impact the trading price of our Common Shares.
Prior to December 31, 2018, we were a foreign private issuer and were therefore not subject to certain United States securities law disclosure requirements that apply to a domestic United States issuer, which may limit the historical information publicly available to our shareholders.
As a foreign private issuer prior to December 31, 2018, we were exempt from certain rules under the Exchange Act that impose disclosure requirements as well as procedural requirements for proxy solicitations under Section 14 of the Exchange Act. In addition, our officers, directors and principal shareholders were exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act. Moreover, we were not required to file periodic reports and financial statements with the SEC as frequently or as promptly as a company that files as a domestic issuer whose securities are registered under the Exchange Act, nor were we generally required to comply with the SEC’s Regulation Fair Disclosure, which restricts the selective disclosure of material non-public information. For as long as we were a “foreign private issuer” or an eligible Canadian issuer under the Multijurisdictional Disclosure System, we filed our annual financial statements on Form 20-F, or on Form 40-F, respectively, and furnished our quarterly updates on Form 6-K to the SEC. However, the information we filed or furnished was not the same as the information required in annual and quarterly reports on Form 10-K or Form 10-Q for United States domestic issuers. Accordingly, there may be less historical information publicly available concerning us than there is for a company that has filed as a domestic issuer for longer.
Data security incidents and privacy breaches could result in important remediation costs, increased cyber security costs, litigation and reputational harm.
Cyber security incidents can result from deliberate attacks or unintentional events. Cyber-attacks and security breaches could include unauthorized attempts to access, disable, improperly modify or degrade the Company’s information, systems and networks, the introduction of computer viruses and other malicious codes and fraudulent “phishing” emails that seek to misappropriate data and information or install malware onto users’ computers. Cyber-attacks in particular vary in technique and sources, are persistent, frequently change and are increasingly more targeted and difficult to detect and prevent against. Our network security and data recovery measures and those of third parties with which we contract, may not be adequate to protect again cyber-attacks.
Disruptions due to cyber security incidents could adversely affect Aptose’s business. In particular, a cyber security incident could result in the loss or corruption of data from Aptose’s research and development activities, including clinical trials, which may cause significant delays to some or all of the Company’s clinical programs. Also, the Company’s trade secrets, including unpatented know how, technology and other proprietary information could be disclosed to competitors further to a breach, which would harm the Company’s business and competitive position. We expect that risks and exposures related to cyber security attacks will remain high for the foreseeable future due to the rapidly evolving nature and sophistication of these threats. While we have invested in the protection of data and information technology, there can be no assurance that our efforts to implement adequate security measures would be sufficient to protect the Company against cyber-attacks.
We must successfully upgrade and maintain our information technology systems.
We rely on various information technology systems to manage our operations. There are inherent costs and risks associated with maintaining, modifying and/or changing these systems and implementing new systems, including potential disruption of our internal control structure, substantial capital expenditures, additional administration and operating expenses, retention of sufficiently skilled personnel to implement and operate its systems, demands on management time and other risks and costs of delays or difficulties in transitioning to new systems or of integrating new systems into our current systems. In addition, our information technology system implementations may not result in productivity improvements at a level that outweighs the costs of implementation, or at all. The implementation of new information technology systems may also cause disruptions in our business operations and have an adverse effect on our business, prospects, financial condition and operating results.

Our Common Shares are currently traded on The Nasdaq Capital Market under the symbol “APTO” and the Toronto Stock Exchange under the symbol “APS”.
As of March 10, 2020, there were approximately 33 shareholders of record of our Common Shares, which included Cede & Co., a nominee for Depository Trust Company, or DTC, and CDS & Co., a nominee for The Canadian Depository for Securities Ltd., or CDS. Common shares that are held by financial institutions as nominees for beneficial owners are deposited into participant accounts at either DTC or CDS, and are considered to be held of record by Cede & Co. or CDS & Co. as one shareholder.
We currently intend to retain all future earnings, if any, for the operation and expansion of our business and, therefore, do not anticipate declaring or paying cash dividends on our Common Shares in the foreseeable future.
Repurchases of Equity Securities
There were no repurchases of equity securities during the fourth quarter of 2019.

OVERVIEW
Aptose Biosciences Inc. (“we”, “our”, “us”, “Aptose” or the “Company”) is a science-driven biotechnology company advancing first-in-class targeted agents to treat life-threatening cancers, such as acute myeloid leukemia (“AML”), high-risk myelodysplastic syndromes (“MDS”), chronic lymphocytic leukemia (“CLL”) and other hematologic malignancies. Based on insights into the genetic and epigenetic profiles of certain cancers and patient populations, Aptose is building a pipeline of novel oncology therapies directed at dysregulated processes and signaling pathways. Aptose is developing targeted medicines for precision treatment of these diseases to optimize efficacy and quality of life by minimizing the side effects associated with conventional therapies. We currently have in development two molecules: CG026806 (“CG-806”) and APTO-253, both being evaluated for safety, tolerability, pharmacokinetics and signals of efficacy in Phase I clinical trials. Each molecule is described below:
CG-806 is an orally administered, highly potent first-in-class pan-FLT3/pan-BTK inhibitor that targets defined clusters of kinases that are operative in hematologic malignancies. This mutationally agnostic small molecule anticancer agent is currently being evaluated in a Phase Ia/b study for the treatment of patients having B-cell malignancies including CLL, small lymphocytic lymphoma (“SLL”) and certain non-Hodgkin’s lymphomas (“NHL”) that are resistant/refractory/intolerant to other therapies. Aptose also is planning for a Phase I study for the development of CG-806 for the treatment of patients with relapsed/refractory acute myeloid leukemia (“R/R AML”), including the emerging populations resistant to FMS-like tyrosine kinase 3 (“FLT3”) inhibitors.
APTO-253 is our Phase I/b-stage small molecule therapeutic agent that inhibits expression of the MYC oncogene without causing, to date, general myelosuppression of the bone marrow. The MYC oncogene is overexpressed in hematologic cancers, including AML and certain B cell malignancies. MYC is a transcription factor that regulates cell growth, proliferation, differentiation and apoptosis, and overexpression of MYC amplifies new sets of genes to promote survival of cancer cells. APTO-253 suppresses expression of the MYC oncogene in AML cells and depletes those cells of the MYC oncoprotein, leading to apoptotic cell death. Indeed, the first AML patient administered the lowest dose level (20 mg/m2) of APTO-253 experienced a significant reduction in the expression of MYC in blood cells (“PBMCs”) during the 28-day cycle of therapy, and no drug-related adverse events were noted. Likewise, the second patient administered APTO-253, this time an MDS patient administered the second dose level (40 mg/m2), also showed a significant reduction in the expression of MYC in PBMCs during the 28-day cycle of therapy, and no drug-related adverse events were noted. Similarly, MYC inhibition was observed in patients in the 66 mg/m2 dose level. Aptose now is dosing and enrolling patients with the fourth dose level (100 mg/m2). Thus, APTO-253 may serve as a safe and effective MYC inhibitor for AML/MDS patients that combines well with other agents and does not significantly impact the normal bone marrow.
PROGRAM UPDATES
CG-806
Indication and Clinical Trials:
CG-806 is being developed with the intent to deliver the agent as an oral therapeutic and to develop it for relapsed and refractory (R/R) AML and for appropriate B cell malignancies (including but not limited to CLL, SLL and NHL).
On March 25, 2019, we announced that the U.S Food and Drug Administration (“FDA”) granted Aptose Investigational New Drug (“IND”) allowance to initiate its Phase I clinical trial for CG-806. The Phase I clinical trial is a multicenter, open label, dose-escalation study with expansions to assess the safety, tolerability, PK, and preliminary efficacy of CG-806 in patients with CLL, SLL or NHL. The initial goal of the trial is to evaluate safety, tolerability, pharmacokinetics and pharmacodynamic effects of CG-806 in these patient populations and to observe for signals of efficacy. In this study, CG-806 is administered in gelatin capsules twice daily (“BID”) during a 28-day cycle.
As of the date of this report, we have initiated eighteen clinical sites for the Phase Ia/b trial in patients with CLL/SLL or NHL and have completed enrollment of patients on the first, second, and third dose cohorts. Under an FDA-approved accelerated titration protocol, only one patient was required at each of the first two dose levels. The first CLL patient at the first dose level received 150mg BID during a 28-day cycle and is continuing on study in their ninth cycle. A second CLL patient was enrolled at the second dose level (300mg BID) during a 28-day cycle, and this patient completed four cycles before discontinuing during the fifth cycle. In this CLL patient, we observed pharmacologic inhibition of phospho-BTK (100% inhibition 4hrs following administration of the first dose), an increase in peripheral blood lymphocytes (or lymphocytosis) classically ascribed as a response to inhibition of BTK, and no treatment related adverse events. Aptose is now dosing three patients enrolled at the third dose cohort (450mg BID). Our Clinical Safety Review Committee reviews relevant data following completion of each cohort, and following completion of the third dose level the committee may approve escalation to the fourth dose level (600mg BID) as appropriate.
Aptose also plans to seek allowance from the FDA to move CG-806 into the AML patient population in a separate Phase I trial. Currently, we are finalizing our efforts to advance into a study in patients with AML. The FDA has granted orphan drug designation to CG-806 for the treatment of patients with AML. Orphan drug designation is granted by the FDA to encourage companies to develop therapies for the treatment of diseases that affect fewer than 200,000 individuals in the United States. Orphan drug status provides research and development tax credits, an opportunity to obtain grant funding, exemption from FDA application fees and other benefits. If CG-806 is approved to treat AML, the orphan drug designation provides us with seven years of marketing exclusivity.
Manufacturing:
We created a scalable chemical synthetic route for the manufacture of CG-806 drug substance and have scaled the manufacture of API (active pharmaceutical ingredient, or drug substance) to multi-kg levels. We manufactured and delivered a batch of API which was used for Dose Range Finding Studies that were performed and completed in early January 2018. We completed in March 2018 the manufacture of a multi-kg batch of Good Laboratory Practice (“GLP”) grade API and then formulated that API into a drug product for use in IND-enabling GLP toxicology studies. We also completed the manufacture of a multi-kg batch of API under Good Manufacturing Product (“GMP”) conditions as our API supply for our first-in-human clinical trials, and we manufactured under GMP conditions two dosage strengths of capsules to serve as our clinical supply in those human studies. Since then, we have completed successful manufacture of multiple batches of API and drug product, and have planned numerous GMP production campaigns to supply the ongoing trial and planned trials into the future. Although we have been able to manufacture API and capsules to support clinical supplies under GMP conditions, research and development funds are being utilized to support further exploratory formulation studies in an ongoing effort to craft a superior formulation for CG-806.
Preclinical Program Updates:
We have completed several non-clinical studies that demonstrate the highly differentiated profile of CG-806. Key studies that have been presented at scientific forums are as follows:
·On April 15, 2018, at the 2018 Annual Meeting of the American Association for Cancer Research (“AACR”), we presented with the OHSU Knight Cancer Institute preclinical data demonstrating that CG-806, a pan-FLT3/pan-BTK inhibitor, demonstrates broader activity and superior potency to other FLT3 and BTK inhibitors against primary bone marrow samples from patients with hematologic malignancies. We also presented preclinical data demonstrating CG-806 targets multiple pathways to kill diverse subtypes of AML and B-cell malignancies in vitro.
·On June 15, 2018, at the 23rd Congress of the European Hematology Association (“EHA”), we presented, during a poster presentation, preclinical data demonstrating a unique binding mode of CG-806 to wild type and C481S mutant BTK. Further, we presented that CG-806 suppresses the BCR, AKT/PI3K, ERK and NFkB signaling pathways and exerts broader and far greater potency of direct cancer cell killing that ibrutinib against malignant bone marrow cells from patients with CLL, ALL and a host of other hematologic malignancies.
·On December 3, 2018, we announced two separate poster presentations at the American Society of Hematology (ASH) Annual Meeting being held on December 1-4, 2018. The OHSU Knight Cancer Institute and Aptose presented data in one poster and the team at The University of Texas MD Anderson Cancer Center (“MDACC”) presented data in a separate poster. These presentations highlighted several key findings. First, in collaboration with the MDACC, orally administered CG-806 demonstrated efficacy in a patient derived xenograft (“PDX”) study in which the bone marrow cells from a patient with AML having dual ITD and D835 mutations in FLT3 were implanted into a mouse. The dual FLT3 mutant form of AML represents a very difficult-to-treat population that has shown resistance to other FLT3 inhibitors, and data from the PDX model suggest that CG-806 may be useful in treating such patients. Secondly, Aptose presented high level data from preclinical GLP toxicology studies that demonstrate orally administered CG-806 is a well-tolerated targeted molecule. Finally, in collaboration with the OHSU Knight Cancer Center, studies of CG-806 on 124 samples of freshly isolated bone marrow from CLL patients demonstrated both broader and greater cell killing potency for CG-806 than Ibrutinib.
·On April 1, 2019, at the 2019 Annual Meeting of the AACR, Aptose, along with our collaborators at OHSU Knight Cancer Institute, presented data highlighting CG-806 was more potent in killing AML patient-derived samples than other FLT3 inhibitors including midostaurin, sorafenib, sunitinib, dovitinib, quizartinib, crenolanib and gilteritinib. CG-806 was equally potent against cells from patients in the adverse, intermediate and favorable risk groups (2017 ELN risk stratification), and cells from patients with relapsed or transformed AML (World Health Organization classification) were as sensitive as those from patients with de novo AML. The data demonstrated potency on primary AML patient samples across all AML subgroups including relapsed/refractory/transformed AML and those with genetic abnormalities related to poor prognosis. While patient samples with FLT3-ITD mutations were expected to have greater sensitivity to CG-806, the most surprising correlation was the sensitivity of patient samples with IDH1 R132 mutations. The enhanced sensitivity of IDH-1 mutant AML to CG-806 warrants investigation in the clinical setting. Moreover, in studies of CG-806 on AML patient bone marrow samples, we demonstrated that mutations in p53, ASXL1 and NPM1 do not hinder the potency of CG-806.
·On June 14, 2019, we presented new preclinical data for CG-806 in a poster presentation at the 24th Congress of the EHA in Amsterdam, the Netherlands. The poster, CG-806, preclinical in vivo efficacy and safety profile as a pan-FLT3 / pan-BTK inhibitor, highlights the in vivo anti-leukemic efficacy of CG-806 and its GLP toxicology and toxicokinetic profile. In a preclinical MV4-11 FLT3-ITD AML xenograft mouse model, CG-806 suppressed leukemia growth at all doses tested throughout the 28-day period of dosing. In the mice treated with 100 mg/kg, 5 of 11 (45%) were cured through day 120, and in the 300 mg/kg group, 10 of 11 (91%) of the mice were cured. Retreating the “uncured’ mice in these two dose groups for an additional 28 days beginning on day 88 led to rapid and robust antitumor response in all retreated mice through day 120. In the “re-treated” mice, no drug resistance and no toxicities were observed. GLP 28-day toxicology and TK studies mice and dogs showed no adverse CG-806-related effects on body weight, ophthalmic, respiratory or neurological examinations, clinical pathology (coagulation, clinical chemistry, or urinalysis), organ weight or macroscopic evaluations. No CG-806-related cardiovascular effects were noted in the 28-day GLP toxicology study or in a separate preclinical cardiovascular safety study.
·On October 24, 2019, we presented preclinical data in a poster presentation at the 5th International Conference on Acute Myeloid Leukemia “Molecular and Translational” Advances in Biology and Treatment in Estoril, Portugal. The poster, CG-806 Pan-FLT3/Pan-BTK Inhibitor Simultaneously Suppresses Multiple Oncogenic Signaling Pathways to Treat AML, highlighted that CG-806 acts on large xenograft tumors with no evidence of drug resistance and with no observed toxicity, enhances killing of patient-derived AML and B-cell cancer cells when combined with venetoclax, and retains activity in patient-derived AML cells even when cells harbor mutations of FLT3, IDH-1, NPM1, ASXL1 or p53.
·On December 8 and 9, 2019, we presented new preclinical data in two separate poster presentations at the 61st Annual American Society of Hematology (“ASH”). On December 8, 2019, the poster CG-806, a First-in-Class Pan-FLT3/Pan-BTK Inhibitor, Exhibits Broad Signaling Inhibition in Chronic Lymphocytic Leukemia Cells compared CG-806 and ibrutinib, the standard of care, on primary patient cells of CLL highlighting that CG-806 broadly inhibits B-cell receptor signaling in CLL cells, resulting in CLL cell apoptosis and reduced proliferation, CG-806 is more potent than ibrutinib in inducing apoptosis of MEC1 CLL cells and, finally, CG-806 targets elements of the CLL microenvironment, and thereby potentially targets pro-survival signals from the microenvironment. The poster presented on December 9, 2019 titled Synergistic Targeting of BTK and E-Selectin/CXCR4 in the Microenvironment of Mantle Cell Lymphomas, explored the effects of CG-806 on cells of MCL, a rare subtype of aggressive B cell non Hodgkin lymphoma that is incurable with standard therapy, and investigated the molecular mechanisms of acquired resistance to treatment, highlighted that CG-806 demonstrated superior anti-lymphoma effects compared with ibrutinib, exerting potent cell growth inhibitory effects on ibrutinib-resistant MCL cells, CG-806 suppresses phospho-BTK, -Stat3, -AKT, -ERK, -Src, NF-kB, and the anti-apoptotic protein Mcl1, while upregulating p53, CG-806 increased autophagy in MCL cells, which may be associated with resistance to CG-806-mediated apoptosis. Inhibition of autophagy re-sensitizes MCL cells to CG-806-induced apoptosis, CG-806 treatment upregulates CXCR4/E-selectin levels in MCL cells and finally, combination of CXCR4/E-selectin antagonists with CG-806 enhances CG-806-induced apoptotic killing of MCL cells in the presence of the tumor microenvironment.
·On December 7, 2019 at the 61st ASH Annual Meeting and Exposition in Orlando, FL Aptose hosted a corporate event and clinical update, where the company’s management and invited Key Opinion Leaders highlighted some early clinical observations on safety, tolerability, pharmacokinetics, and activity, including. The discussion focused on key findings from dose levels one and two of CG-806 in heavily pretreated R/R CLL patients, including: the clean safety profile to date, with no myelosuppression, drug-related adverse events or dose-limiting toxicity observed; meaningful oral absorption and predictable pharmacokinetic (PK) profile; evidence of target engagement manifesting as inhibition of Phospho-BTK, Phospho-SYK and Phospho-ERK in a plasma inhibitory assay (PIA) using plasma from the CLL patient on dose level two, and early evidence of clinical activity in the same patient manifesting as increase in peripheral blood lymphocytes (lymphocytosis), typically associated with BTK inhibition.
APTO-253
Phase Ib Trial
APTO-253, a small molecule inhibitor of MYC gene expression, is being evaluated in a Phase Ib clinical trial in patients with R/R hematologic malignancies, particularly R/R-AML and high-risk MDS. The Phase Ib, multicenter, open-label, dose-escalation clinical trial of APTO-253 is designed to assess the safety, tolerability, pharmacokinetics and pharmacodynamic responses and efficacy of APTO-253 as a single agent and determine the recommended Phase II dose. APTO-253 is being administered once weekly, over a 28-day cycle. The dose escalation stage of the study could potentially enroll up to 20 patients with R/R-AML or high-risk MDS. The study is designed to then transition, as appropriate, to single-agent expansion cohorts in R/R-AML and/or high-risk MDS.
As of the date of this report, we have eight active sites recruiting patients in the dose escalation stage of the trial. The first patient, having AML, was dosed with 20mg/m2 and successfully completed the 28-day cycle. As only one patient was required at the first dose level, we then placed an MDS patient on the second dose level of 40mg/m2, and that patient successfully completed the 28-day cycle. We then successfully fulfilled the third cohort with three patients completing the 28-day cycle at a dose level of 66mg/m2. Following review of relevant data and approval by our Clinical Safety Review Committee, we began enrolling patients into the fourth cohort at a dose level of 100mg/m2. At the first three dose levels, we observed meaningful reductions in MYC expression in peripheral blood mononuclear cells (PBMCs) from patients with the new formulation of APTO-253.
We are continuing to manufacture additional drug substance and drug product for use in the ongoing trial. We completed manufacture of a second 2kg GMP batch of drug substance and recently used that drug substance to complete the manufacture of a batch of GMP drug product.
We are exploring additional drug delivery methods for APTO-253 and plan to initiate additional non-clinical studies for solid tumor and hematologic cancer development. As preparing, submitting, and advancing applications for regulatory approval, developing drugs and drug product and clinical trials are sometimes complex, costly, and time-consuming processes, an estimate of the future costs is not reasonable at this time.
As reported previously, APTO-253 was placed on clinical hold by the FDA in November 2015 due to deficiencies in the drug product that was manufactured prior to 2013. Those shortcomings of the drug product were addressed and the clinical hold was lifted. More specifically, the Phase Ib trial of APTO-253 was placed on clinical hold as a consequence of an event that occurred at a clinical site with during an infusion procedure that involved precipitation of the drug substance from the pre-2013 drug product. Importantly, Aptose acted to withhold infusion of that batch of APTO-253 drug product and no patients were put at risk. Ultimately, a root cause investigation determined that the event resulted from chemistry and manufacturing based issues. Consequently, Aptose manufactured a modified batch of API and formulated drug product, the details of which were incorporated into a Chemistry, Manufacturing and Control amendment to the IND application.
Immediately upon occurrence of the infusion event, the Phase Ib trial was placed on clinical hold in order to solve a chemistry-based formulation issue, and the chemistry of the API and the formulation had undergone minor modifications to deliver a stable and soluble drug product for return to the clinical setting. In December 2016, we had successfully manufactured multiple non-GMP batches of a new drug product formulation for APTO-253; however, a batch that was the intended clinical supply encountered an unanticipated mishap during the filling process that compromised the stability of that batch of drug product. We conducted formal root cause analyses studies, identified the reason for the drug product stability failure, and established a corrective and prevention action plan for the manufacture of future batches of drug product. During the first quarter of 2018, we manufactured a new GMP clinical supply of drug product and performed studies required to demonstrate the fitness of the drug product for clinical usage. The release specifications for the new clinical supply were met, and we presented the findings to the FDA in the second quarter of 2018.
On June 28, 2018, the FDA notified us that it had lifted the clinical hold on APTO-253 and the clinical trial was re-initiated on June 29, 2018.
We then completed all tasks required to return APTO-253 to the Phase Ib clinical trial.
Preclinical data presented at scientific forums are as follows:
·On April 17, 2018, at the 2018 Annual Meeting of the AACR, we presented preclinical data demonstrating that APTO-253 is a new addition to the repertoire of drugs that can exploit DNA BRCA1/2 deficiency, broadening the potential applicability of APTO-253 towards solid cancer indications.
·On June 4, 2018, we announced that preclinical data elucidating the mechanism of action of APTO-253 were published in two separate articles in the June 2018 issue (Volume 17, Number 6) of Molecular Cancer Therapeutics, a peer-reviewed journal of the AACR. The most important finding disclosed in the published articles is the ability of the APTO-253 small molecule to bind to and stabilize a G-quadruplex DNA motif found in the promoter regulatory region of the MYC oncogene and to inhibit expression of the MYC gene, thereby depleting the cells of the MYC oncoprotein and leading to cancer cell death. These findings make APTO-253 the only clinical stage molecule that can directly target the MYC gene and inhibit its expression.
·On April 1, 2019, at the 2019 Annual Meeting of the AACR, we presented in vitro studies that further define the mechanism of action of APTO-253. Researchers found that APTO-253 targets a G-quadruplex motif in the P1/P2 promoter region of the MYC gene and inhibits MYC gene expression to induce apoptosis, resulting in its ability to potently kill hematologic malignant cell lines and primary samples from AML and CLL patients. In this study, researchers performed long-term in vitro studies to determine if and how cells might develop resistance to APTO-253. MYC driven Raji cells required three years in increasing concentrations of APTO-253 in order to adopt multiple modifications and develop high level resistance to APTO-253. These modifications include up-regulation of the ABCG2 transporter, acquisition of a more stable MYC protein lacking the conserved core sequence of MYC Box III generated by deletion of an internal region of the MYC gene exon 2, and utilization of alternate P3 promoter not inhibited by G4 binding and stabilization. Importantly, these studies confirmed the MYC gene as a target of APTO-253.
LIQUIDITY AND CAPITAL RESOURCES
We are an early stage development company and we currently do not earn any revenues from our drug candidates. The continuation of our research and development activities and the commercialization of the targeted therapeutic products are dependent upon our ability to successfully finance and complete our research and development programs through a combination of equity financing and payments from strategic partners. We have no current sources of significant payments from strategic partners.
Sources of liquidity:
The following table presents our cash and cash equivalents, investments and working capital as at December 31, 2019 and 2018.
Working capital represents primarily cash, cash equivalents, investments and other current assets less current liabilities. Current liabilities of approximately $5.5 million as at December 31, 2019 included approximately $521 thousand related to the current portion of the Company’s lease liability. There was no comparable amount in current liabilities of approximately $2.79 million as at December 31, 2018. See “Critical Accounting Policies” below.
We believe that our cash, cash equivalents and investments on hand at December 31, 2019 will be sufficient to finance our operations for at least 12 months from the issuance date of these financial statements. Our cash needs for the next twelve months include estimates of the number of patients and rate of enrollment of our clinical trials, the amount of drug product that we will require to support our clinical trials, and our general corporate overhead costs to support our operations,and our reliance on our manufacturers. We have based these estimates on assumptions and plans which may change and which could impact the magnitude and/or timing of operating expenses and our cash runway. Since our inception, we have financed our operations and technology acquisitions primarily from equity financing, proceeds from the exercise of warrants and stock options, and interest income on funds held for future investment. We expect that we will need to raise additional capital or incur indebtedness to continue to fund our operations in the future. Our ability to raise additional funds could be affected by adverse market conditions, the status of our product pipeline and various other factors and we may be unable to raise capital when needed, or on terms favorable to us. If necessary funds are not available, we may have to delay, reduce the scope of, or eliminate some of our development programs, potentially delaying the time to market for any of our product candidates.
Cash flows:
The following table presents a summary of our cash flows for the years ended December 31, 2019 and 2018:
Cash used in operating activities:
Our cash used from operating activities for the years ended December 31, 2019 and 2018 was approximately $21.6 million and $23.2 million, respectively. Our uses of cash for operating activities for both years primarily consisted of salaries and wages for our employees, facility and facility-related costs for our offices and laboratories, fees paid in connection with preclinical and clinical studies, drug manufacturing costs, laboratory supplies and materials, and professional fees. In the year ended December 31, 2018, our use of cash from operating activities also included $5.0 million in license fees to CG for development and commercialization rights to CG-806 for all territories outside of South Korea.
We do not expect to generate positive cash flow from operations for the foreseeable future due to additional research and development costs, including costs related to drug discovery, preclinical testing, clinical trials, and manufacturing, as well as operating expenses associated with supporting these activities, and potential milestone payment to our collaborators. It is expected that negative cash flow will continue until such time, if ever, that we receive regulatory approval to commercialize any of our products under development and/or royalty or milestone revenue from any such products exceeds expenses.
Cash flow from investing activities:
Our cash used by investing activities for the year ended December 31, 2019 was $17.4 million, and consisted of net purchases of investments of $17.3 million and purchases of property and equipment of $102 thousand. Our cash provided by investing activities in the year ended December 31, 2018 was $12 thousand, and consisted of maturities of investments of $341 thousand and offset by purchases of property and equipment of $329 thousand. The composition and mix of cash, cash equivalents and investments is based on our evaluation of conditions in financial markets and our near-term liquidity needs. We have exposure to credit risk, liquidity risk and market risk related to our investments. The Company manages credit risk associated with its cash and cash equivalents and investments by maintaining minimum standards of R1-low or A-low investments. The Company invests only in highly rated corporations which are capable of prompt liquidation. The Company manages its liquidity risk by continuously monitoring forecasts and actual cash flows. The Company is subject to interest rate risk on its cash and cash equivalents and investments. The Company does not believe that the results of operations or cash flows would be affected to any significant degree by a sudden change in market interest rates relative to interest rates on the investments, owing to the relative short-term nature of the investments.
Cash flow from financing activities:
Our cash flow from financing activities for the years ended December 31, 2019 and 2018 was approximately $103.4 million and $27.9 million, respectively. During the year ended December 31, 2019, we raised net proceeds of approximately $88.2 million from two confidentially marketed public offerings, approximately $14.4 million from the issuance of Common Shares pursuant to the 2018 and 2019 Purchase Agreements (as defined below), $178 thousand from the issuance of Common Shares pursuant to the 2019 ATM Facility (as defined below) and $718 thousand from the issuance of Common Shares pursuant to exercise of employee stock options. During the year ended December 31, 2018, we raised net proceeds of approximately $16.9 million from the issuance of Common Shares pursuant to the 2017 and 2018 Purchase Agreements (as defined below), $10.7 million from the issuance of Common Shares pursuant to the 2018 ATM Facility (as defined below) and $240 thousand from the issuance of Common Shares pursuant to exercise of employee stock options.
On June 3, 2019, we completed a confidentially marketed public offering through the issuance of 11,500,000 Common Shares at a price of $1.85 per Common Share, which included the exercise in full by the underwriters of their option to purchase 1,500,000 additional Common Shares. The gross proceeds from the offering were approximately $21.3 million ($19.6 million net of share-issue costs).
On December 19, 2019, we completed a confidentially marketed public offering through the issuance of 18,543,750 Common Shares at a price of $4.00 per Common Share, which included the exercise in full by the underwriters of their option to purchase 2,418,750 additional Common Shares. The gross proceeds from the offering were approximately $74.2 million. ($68.6 million net of share-issue costs).
On October 27, 2017, we entered into a Common Share Purchase Agreement (the “2017 Purchase Agreement”) with Aspire Capital Fund, LLC (“Aspire Capital”) to sell up to $15.5 million of Common Shares to Aspire Capital. We issued 321,429 Common Shares at a value of $1.40 per share to Aspire Capital as consideration for Aspire Capital entering into the 2017 Purchase Agreement. Under the terms of the 2017 Purchase Agreement, in October 2017, Aspire Capital made an initial purchase of 357,143 Common Shares at a price of $1.40 per share, representing gross proceeds of approximately $500.0 thousand ($324.0 thousand net of share issue costs). During the year ended December 31, 2018, we issued 5,231,953 Common Shares under the 2017 Purchase Agreement at an average price of $2.87 for gross and net proceeds of approximately $15 million. On a cumulative basis, we raised a total of $15.5 million in gross proceeds under the 2017 Purchase Agreement, the maximum amount that was available under the 2017 Purchase Agreement.
On May 30, 2018, we entered into a second Common Share Purchase Agreement (the “2018 Purchase Agreement”) with Aspire Capital to sell up to $20.0 million of Common Shares to Aspire Capital. Under the terms of the 2018 Purchase Agreement, we issued 170,261 Common Shares at a value of $3.524 per share to Aspire Capital as consideration for Aspire Capital entering into the 2018 Purchase Agreement and, during the year ended December 31, 2018, we issued 907,547 Common Shares at an average price of $2.12 per share for gross and net proceeds of approximately $1.9 million. During the year ended December 31, 2019, the Company issued 5,502,433 additional Common Shares under the 2018 Purchase Agreement at an average price of $1.82 per share for gross and net proceeds of $10 million. On a cumulative basis to May 24, 2019, we raised a total of approximately $11.9 million gross proceeds and issued 6,409,980 Common Shares, the maximum number of shares issuable under this facility without shareholder approval.
On May 7, 2019, we entered into a third Common Share Purchase Agreement (the “2019 Purchase Agreement”) with Aspire Capital to sell up to $20.0 million of Common Shares to Aspire Capital. Under the terms of the 2019 Purchase Agreement, Aspire Capital has committed to purchase up to an aggregate of $20.0 million of our Common Shares, at our request from time to time during a 30-month period beginning on the effective date of a registration statement related to the transaction and at prices based on the market price at the time of each sale. Under the terms of the 2019 Purchase Agreement, we issued 171,428 Common Shares at a value of $2.10 per share to Aspire Capital as consideration for Aspire Capital entering into the 2019 Purchase Agreement, and during the year ended December 31, 2019, we issued 1,800,000 Common Shares at an average price of $2.43 per share for gross and net proceeds of approximately $4.37 million. The 2019 Purchase Agreement was terminated on December 16, 2019.
On March 27, 2018, we entered into an at-the-market equity facility (the “2018 ATM Facility”) with Cantor Fitzgerald & Co (“Cantor Fitzgerald”), acting as sole agent. Under the terms of this facility, we could, from time to time, sell Common Shares having an aggregate offering value of up to $30 million through Cantor Fitzgerald. We determined, at our sole discretion, the timing and number of shares to be sold under the 2018 ATM Facility. During the year ended December 31, 2018, we issued 4,085,615 Common Shares under the 2018 ATM Facility at an average price of $2.71 per share for gross proceeds of approximately $11 million ($10.7 million net of share issue costs). During the period from January 1, 2019 to May 24, 2019, the date the 2018 ATM Facility was terminated, the Company issued 77,349 shares under the 2018 ATM Facility at an average price of $2.37 per share for gross proceeds of $183 thousand ($178 thousand net of share issue costs). Costs associated with the proceeds consisted of a 3% cash commission. On a cumulative basis to May 24, 2019, the Company raised a total of $11.2 million gross proceeds ($10.9 million net of share issue costs) under the 2018 ATM Facility.
On May 24, 2019, we entered into an at-the-market equity facility (the “2019 ATM Facility”) with Piper Jaffray & Co. (now Piper Sandler Companies) and Canaccord Genuity LLC, acting as co-agents. The 2019 ATM Facility replaced the 2018 ATM Facility that we had entered into with Cantor Fitzgerald. The 2019 ATM Facility allowed us to instruct our co-agents to offer up to approximately 20.2 million Common Shares, having an aggregate offering value of up to $40.0 million, at the prevailing market price from time to time. The Company did not issue any shares under the 2019 ATM Facility, and on December 16, 2019, the Company terminated the 2019 ATM Facility.
Contractual Obligations and Off Balance Sheet Financing
At December 31, 2019, we had contractual obligations requiring annual payments as follows:
(1)Consists primarily of lease obligations for our executive offices in San Diego, California, our Headquarters in Toronto, Ontario, and a research facility located in San Diego, California.
The table above does not include certain general and administrative and development support services under agreements we can cancel without significant penalty.
As at December 31, 2019, we have not entered into any off-balance sheet arrangements. The Company enters into research, development and license agreements in the ordinary course of business where the Company receives research services and rights to proprietary technologies. Milestone and royalty payments that may become due under various agreements are dependent on, among other factors, clinical trials, regulatory approvals and ultimately the successful development of a new drug, the outcome and timing of which is uncertain.
Under the license agreement with CG, the Company has obligations for development milestones of $16 million related to the initiation of Phase II and pivotal clinical trials, and regulatory milestones totaling $44 million. The Company also has an obligation to pay royalty payments on sales of commercialized product. The timing of any milestone or royalty payments that may become due is not yet determinable.
On June 13, 2018, we entered into a license agreement with CG to gain an exclusive license to CG-806 in China (including the People’s Republic of China, Hong Kong and Macau). The Company has future obligations of development milestones of $6 million related to approval of an IND and to the initiation of Phase II and pivotal clinical trials, and regulatory milestones totaling $20 million. The Company also has an obligation to pay sales milestones and royalty payments on sales of commercialized product. The timing of any milestone or royalty payments that may become due is not yet determinable.
RESULTS OF OPERATIONS
A summary of the results of operations for the years ended December 31, 2019 and 2018 is presented below:
Net loss of $26.3 million for the year ended December 31, 2019 decreased by approximately $2.6 million as compared with $28.9 million for the year ended December 31, 2018, primarily as a result of a decline in research and development expenses of $5.0 million in license fees paid to CG for development and commercial rights of CG-806 in fiscal 2018 and a decrease in stock option compensation expense of approximately $2.0 million, offset by increased expenditures of approximately $3.7 million on our CG-806 and 253 development programs, reflecting program costs and related labor and higher cash-based general and administrative expenses of $1 million in the year ended December 31, 2019. The net loss was also lower in 2019 due to higher net finance income, which increased by $341 thousand compared to 2018, mostly as a result of higher interest earned on larger balances of cash equivalents and investments held during the year ended December 31, 2019.
Research and Development Expenses
The research and development expenses for the years ended December 31, 2019 and 2018 were as follows:
Research and development expenses of $16.8 million for the year ended December 31, 2019, decreased by approximately $1.9 million compared with $18.7 million for the prior year, primarily as a result of the following events:
·License fees paid in the year ended December 31, 2018 to CG of $2.0 million for development and commercial rights of CG-806 in all territories outside of Korea and China, and a further $3.0 million paid for development and commercial rights of CG-806 in China. CG is eligible for development, regulatory and commercial-based milestones as well as royalties on future product sales. There were no license fees paid to CG or other collaborators in the year ended December 31, 2019.
·An increase in research and development activities related to our CG-806 development program of approximately $2.4 million, mostly as a result of increases to our clinical trial operating costs for our CG-806 BCM phase Ib clinical trial and planned CG-806 AML phase I clinical trial. For the year ended December 31, 2019, program costs consisted mostly of manufacturing costs to supply our clinical trials, operating costs to conduct our CG-806 BCM phase Ib clinical trial, which was approved by the FDA in March 2019, as well as preparation costs for our planned CG-806 AML clinical trial. For the year ended December 31, 2018, program costs consisted mostly of manufacturing costs to supply our clinical trials, for preclinical studies to support the IND application we filed in February of 2019 to test CG-806 in patients with BCM, and for consultant and CRO costs to prepare for the CG-806 BCM trial.
·A decrease in research and development activities related to our APTO-253 development program of approximately $313 thousand related to lower manufacturing costs to supply the trial, and offset by an increase in costs associated with conducted the phase Ia/b clinical trial for APTO-253. For both the fiscal years ended December 31, 2018 and 2019, program costs consisted of costs for manufacturing APTO-253 to supply the trial, and for operating costs to conduct the ongoing phase Ib clinical trial. The APTO-253 clinical trial, which had been on a clinical hold since November 2015 was taken off clinical hold in June 2018.
·An increase in personnel expenses of $1.6 million in the year ended December 31, 2019, as compared with prior year mostly related to additional clinical research staff to support two Phase I clinical trials. At December 31, 2019, we had 23 employees in research and development, including clinical operations as compared to 16 employees as at December 31, 2018.
·A decrease in stock option compensation of approximately $552 in the year ended December 31, 2019, related mostly to higher forfeitures in the year ended December 31, 2019, as well faster vesting of certain stock options granted in the period ended December 31, 2018. In the three-month period ended March 31, 2018, 100,000 stock options with a grant date fair value of $2.03 vested immediately, contributing to higher expenses in that period.
General and Administrative Expenses
The general and administrative expenses for the years ended December 31, 2019 and 2018 are as follows:
General and administrative expenses of $10.0 million for the year ended December 31, 2019, decreased by approximately $352 thousand as compared with $10.4 million for the prior year. Changes to the components of our general and administrative expenses presented in the table above are primarily as a result of the following:
·General and administrative expenses, other than stock-based compensation and depreciation of equipment increased by approximately $1.0 million to $8.1 million for the year ended December 31, 2019, primarily as a result of higher compensation costs, increased travel, rent, consulting and office administrative costs associated with additional employees to support increased operations of the Company, and offset by lower professional and regulatory costs.
·Stock-based compensation decreased for the year ended December 31, 2019, by approximately $1.4 million compared with the year ended December 31, 2018, mostly related to faster vesting of certain stock options granted in 2018 when 850,000 of the approximately 1.7 million stock options granted had immediate vesting.
CRITICAL ACCOUNTING POLICIES
Critical Accounting Policies and Estimates
We periodically review our financial reporting and disclosure practices and accounting policies to ensure that they provide accurate and transparent information relative to the current economic and business environment. As part of this process, we have reviewed our selection, application and communication of critical accounting policies and financial disclosures. Management has discussed the development and selection of the critical accounting policies with the Audit Committee of the Board of Directors and the Audit Committee has reviewed the disclosure relating to critical accounting policies in this MD&A.
Significant accounting judgments and estimates
Management’s assessment of our ability to continue as a going concern involves making a judgment, at a particular point in time, about inherently uncertain future outcomes and events or conditions. Please see the “Liquidity and Capital Resources” section in this document for a discussion of the factors considered by management in arriving at its assessment.
Other important accounting policies and estimates made by management are the valuation of contingent liabilities, the valuation of tax accounts, and the assumptions used in determining the valuation of share-based compensation.
Valuation of contingent liabilities:
The Company utilizes considerable judgment in the measurement and recognition of provisions and the Company’s exposure to contingent liabilities. Judgment is required to assess and determine the likelihood that any potential or pending litigation or any and all potential claims against the Company may be successful. The Company must estimate if an obligation is probable, as well as quantify the possible economic cost of any claim or contingent liability. Such judgments and assumptions are inherently uncertain. The increase or decrease of one of these assumptions could materially increase or decrease the fair value of the liability and the associated expense.
Valuation of tax accounts:
Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of future taxable income. Currently, the Company has deductible temporary differences which would create a deferred tax asset. Deferred tax assets are recognized for all deductible temporary differences to the extent that it is probable that future taxable profit will be available against which the deductible temporary differences can be utilized. Management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits together with future tax planning strategies. To date, the Company has determined that none of its deferred tax assets should be recognized. The Company’s deferred tax assets are mainly comprised of its net operating losses from prior years and prior year research and development expenses not yet deducted for income tax purposes. These tax pools relate to entities that have a history of losses, have varying expiry dates, and may not be used to offset taxable income. As well, there are no taxable temporary differences or any tax planning opportunities available that could partly support the recognition of these losses as deferred tax assets. The generation of future taxable income could result in the recognition of some portion or all of the remaining benefits, which could result in an improvement in the Company’s results of operations through the recovery of future income taxes.
Valuation of share based compensation
Management measures the costs for share based payments using market based option valuation techniques. Assumptions are made and judgment is used in applying valuation techniques. These assumptions and judgments include estimating the future volatility of the share price, expected dividend yield, and expected life of the options. The Company uses historical data to estimate the expected dividend yield and expected volatility of its Common Shares in determining the fair value of stock options. The expected life of the options represents the estimated length of time the options are expected to remain outstanding. Such judgments and assumptions are inherently uncertain. The increase or decrease of one of these assumptions could materially increase or decrease the fair value of share based payments and share purchase warrants issued and the associated expense.
The weighted average assumptions that were used in the Black Scholes option pricing model to determine the fair value of stock options granted during the periods ended December 31, 2019 and 2018, respectively, are presented in Note 11 to the consolidated financial statements.
Leases
Effective January 1, 2019, the Company adopted Financial Accounting Standards Board, or FASB, standard ASU No. 2016-02, “Leases (Topic 842)”. The Company’s operating leases of tangible property with terms greater than twelve months are recognized as right of use assets, which represents the lessee’s right to use, or control the use of, a specified asset for the lease term, and a corresponding lease liability, which represents the lessee’s obligation to make lease payments under a lease, measured on a discounted basis. The Company adopted the new standard using the alternative transition method, which permits a company to use its effective date as the date of initial application without restating comparative period financial statements. Landlord inducements in the form of free rent periods are netted against lease payments to the landlord in measuring right-of-use assets and lease liabilities.
Impact of adoption:
As a result of adopting Topic 842, we recorded as of January 1, 2019, a right of use asset of approximately $1.570 million, and a lease liability of approximately $1.647 million. Upon adoption, landlord inducements of approximately $78 thousand were de-recognized, and a corresponding adjustment was made to right-of-use assets.
Updated share information
As at March 10, 2020, we had 76,269,806 Common Shares issued and outstanding. In addition, there were 11,597,968 Common Shares issuable upon the exercise of 11,557,968 outstanding stock options and upon the vesting of 40,000 outstanding restricted share units.

ITEM 9A. CONTROLS AND PROCEDURES
As of the end of our fiscal year ended December 31, 2019, an evaluation of the effectiveness of our “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the United States Securities Exchange Act of 1934) was carried out by our management, with the participation of our principal executive officer and principal financial officer. Based upon that evaluation, our principal executive officer and principal financial officer have concluded that as of the end of that fiscal year, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officers, to allow timely decisions regarding required disclosure.
It should be noted that while our principal executive officer and principal financial officer believe that our disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all errors or fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our principal executive and financial officer, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.
As of December 31, 2019, our management assessed the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework). Based on this assessment, our management concluded that, as of December 31, 2019, our internal control over financial reporting was effective based on those criteria. We are an “emerging growth company,” as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act.
CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the 1934 Act) during our fiscal quarter ended December 31, 2019, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors Aptose Biosciences Inc.
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated statements of financial position of Aptose Biosciences Inc. (the “Company”) as of December 31, 2019 and 2018, the related consolidated statements of loss and comprehensive loss, changes in shareholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2019, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.
Change in Accounting Principle
As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for leases on January 1, 2019, due to the adoption of Financial Accounting Standards Board, ASU No. 2016-02, Leases (Topic 842).
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
We have served as the Company’s auditor since 2003.

1.Reporting entity:
Aptose Biosciences Inc. (“Aptose” or the “Company”) is a clinical-stage biotechnology company committed to discovering and developing personalized therapies addressing unmet medical needs in oncology. The Company’s executive office is located in San Diego, California and its corporate office is located in Toronto, Canada.
Aptose has two clinical-stage programs and a third program that is discovery-stage and partnered with another company. CG026806 (“CG-806”), Aptose’s mutation-agnostic FMS-like tyrosine kinase 3 (FLT3 / Bruton’s tyrosine kinase (BTK) inhibitor, is currently enrolling patients in a Phase 1a/b, multicenter, open label, dose-escalation study with expansions to assess the safety, tolerability, PK, and preliminary efficacy of CG-806 in patients with chronic lymphocytic leukemia (CLL/SLL) or non-Hodgkin lymphomas (NHL). Aptose plans to seek allowance from the FDA to move into patient populations that include relapsed or refractory acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) in a separate Phase 1 trial. APTO-253, Aptose’s second program, is a small molecule MYC inhibitor and is currently enrolling patients in a Phase 1b clinical trial for the treatment of patients with R/R blood cancers, including AML and high-risk Myelodysplastic Syndrome.
Since our inception, we have financed our operations and technology acquisitions primarily from equity financing, proceeds from the exercise of warrants and stock options, and interest income on funds held for future investment. Our uses of cash for operating activities have primarily consisted of salaries and wages for our employees, facility and facility-related costs for our offices and laboratories, fees paid in connection with preclinical and clinical studies, drug manufacturing costs, laboratory supplies and materials, and professional fees.
During the year ended December 31, 2019, the Company completed two confidentially marketed public offering (CMPO) through the issuance of 30,043,750 common shares for gross proceeds of $95.45 million (approximately $88.18 million net of share issue costs). The Company also raised capital pursuant to two separate share purchase agreement with Aspire Capital (Aspire) through the issuance of 7,302,433 common shares for gross and net proceeds of $14.4 million.
We do not expect to generate positive cash flow from operations for the foreseeable future due to the early stage of our clinical trials. It is expected that negative cash flow will continue until such time, if ever, that we receive regulatory approval to commercialize any of our products under development and/or royalty or milestone revenue from any such products exceeds expenses.
We believe that our cash, cash equivalents and investments on hand at December 31, 2019 will be sufficient to finance our operations for at least 12 months from the issuance date of these financial statements. We have based these estimates on assumptions and plans which may change and which could impact the magnitude and/or timing of operating expenses and our cash runway. These estimates include the rate of enrolment and timing and release of the results of our clinical trials, and our reliance on our manufacturers.
We expect that we will need to raise additional capital or incur indebtedness to continue to fund our operations in the future. Our ability to raise additional funds could be affected by adverse market conditions, the status of our product pipeline and various other factors and we may be unable to raise capital when needed, or on terms favorable to us. If necessary funds are not available, we may have to delay, reduce the scope of, or eliminate some of our development programs, potentially delaying the time to market for any of our product candidates.
2.Significant accounting policies
(a)Basis of consolidation:
These consolidated financial statements include the accounts of its subsidiaries. All intercompany transactions, balances, revenue and expenses are eliminated on consolidation.
(b)Basis of presentation:
These consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States, or GAAP and the rules and regulations of the Securities and Exchange Commission, or SEC, related to annual reports filed on Form 10-K. The functional and presentation currency of the Company is the US dollar.
(c)Significant accounting policies, estimates and judgments:
The preparation of the consolidated financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies and reported amounts of assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting period. Actual outcomes could differ from those estimates. The consolidated financial statements include estimates, which, by their nature, are uncertain.
The impacts of such estimates are pervasive throughout the consolidated financial statements and may require accounting adjustments based on future occurrences.
The estimates and underlying assumptions are reviewed on a regular basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected.
(d)Leases
Effective January 1, 2019, the Company adopted Financial Accounting Standards Board, or FASB, standard ASU No. 2016-02, “Leases (Topic 842)”. The Company’s operating leases of tangible property with terms greater than twelve months are recognized as right of use assets, which represents the lessee’s right to use, or control the use of, a specified asset for the lease term, and a corresponding lease liability, which represents the lessee’s obligation to make lease payments under a lease, measured on a discounted basis. The Company adopted the new standard using the alternative transition method, which permits a company to use its effective date as the date of initial application without restating comparative period financial statements. Landlord inducements in the form of free rent periods are netted against lease payments to the landlord in measuring right-of-use assets and lease liabilities.
Impact of adoption:
As a result of adopting Topic 842, we recorded as of January 1, 2019, a right of use asset of approximately $1.570 million, and a lease liability of approximately $1.647 million. Upon adoption, landlord inducements of approximately $78 thousand were de-recognized, and a corresponding adjustment was made to right-of-use assets.
(e)Cash and cash equivalents:
Cash and cash equivalents are short-term highly liquid investments with original maturities of 90 days or less as at the date of purchase. Cash equivalents are accounted for on amortized cost basis, which approximates its fair value due to their short-term maturities.
(f)Investments:
Investments consist of time deposits with original maturities greater than 90 days are classified by management as securities available-for-sale. These available-for-sale securities are recorded at estimated fair values. Unrealized gains and losses on these investments are recorded in accumulated other comprehensive income (AOCI) in shareholder’s equity. Realized gains and losses and declines in value that are judged to be other than temporary are included in interest income.
(g)Concentration of risk:
The Company is subject to credit risk from the Company’s cash and cash equivalents and investments. The carrying amount of the financial assets represents the maximum credit exposure. The Company manages credit risk associated with its cash and cash equivalents and investments by maintaining minimum standards of R1-low or A-low investments and the Company invests only in highly rated Canadian corporations which are capable of prompt liquidation.
(h)Property and equipment:
Property and equipment is measured at cost less accumulated depreciation and accumulated impairment losses. Cost includes expenditures that are directly attributable to the acquisition of the asset. The Company records depreciation at rates that charge operations with the cost of the assets over their estimated useful lives on a straight-line basis as follows:
The residual value, useful life and methods of depreciation of the assets are reviewed at each reporting period and adjusted prospectively if appropriate.
(i)Research and development:
Research and development (R&D) costs are expensed as incurred. R&D costs consist primarily of salaries and benefits, stock-based compensation, manufacturing, contract services, clinical trials, intangibles, and research related overhead. Non-refundable advance payments for goods and services that will be used in future research are recorded in prepaid and other assets and are expensed when the services are performed.
(j)Fair value:
The Company measures its financial assets and liabilities at fair value. The carrying amounts for the Company’s financial instruments, including cash and cash equivalents, accounts payable and accrued liabilities approximate their fair value due to their short maturities. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
(k)Stock-based compensation:
The Company has a stock-based compensation plan (the “Plan”) available to officers, directors, employees and consultants with grants under the Plan approved by the Company’s Board of Directors. Under the Plan, the exercise price of each option equals the closing trading price of the Company’s stock on the day prior to the grant if the grant is made during the trading day or the closing trading price on the day of grant if the grant is issued after markets have closed. Vesting is provided for at the discretion of the Board of Directors and the expiration of options is to be no greater than 10 years from the date of grant.
The Company uses the fair value based method of accounting for employee awards granted under the Plan. The Company calculates the fair value of each stock option grant using the Black-Scholes option pricing model at the grant date. The stock-based compensation cost of the options is recognized as stock-based compensation expense over the relevant vesting period of the stock options using an estimate of the number of options that will eventually vest.
Stock options awarded to non-employees are accounted for at the fair value of the goods received or the services rendered. The fair value is measured at the grant date. In June 2018, FASB issued accounting standards update No 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. The amendment establishes that nonemployee share-based payment awards within the scope of Topic 718 be measured at grant-date fair value of the equity instruments issued. The amendments are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted and the Company elected to early adopt this policy. The early adoption did not result in any changes in retained earnings or other components of equity as the accounting.
The Company has a stock incentive plan pursuant to which the Board may grant stock-based awards comprised of restricted stock units or dividend equivalents to employees, officers, consultants, independent contractors, advisors and non-employee directors of the Company. Compensation cost for restricted share units is measured at fair value at the date of grant, which is the market price of the underlying security, and is expensed over the award’s vesting period on a straight-line basis using an estimate of the number of awards that will eventually vest.
(l)Segment reporting:
Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker, or CODM. The Company’s Chief Executive Officer serves as its CODM. The Company views its operations and manages its business as one segment, which is the discovery and development of personalized therapies addressing unmet medical needs in oncology. The Company operates primarily in the US.
(m)Loss per share:
Basic loss per share is computed by dividing the net loss available to common shareholders by the weighted average number of shares outstanding during the year. Diluted loss per share is computed similarly to basic loss per share except that the weighted average share outstanding is increased to include additional shares for the assumed exercise of stock options and warrants, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and warrants were exercised and that the proceeds from such exercises were used to acquire common stock at the average market price during the year. The inclusion of the Company’s stock options and warrants in the computation of diluted loss per share has an anti-dilutive effect on the loss per share and, therefore, they have been excluded from the calculation of diluted loss per share.
(n)Income taxes:
The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted rates in effect for the year in which these temporary differences are expected to be recovered or settled. Valuation allowances are provided if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions and other issues. Reserves are based on a determination of whether and how much of a tax benefit taken by the Company in its tax filing is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions are recorded as components of income tax expense. As at December 31, 2019 and December 31, 2018, the Company has not recorded any reserves for potential payments as the Company has a history of losses and does not have any revenue from operations.
3.Cash and cash equivalents:
Cash and cash equivalents consists of cash of $1.640 million (December 31, 2018 - $621 thousand) and deposits in high interest savings accounts and other term deposits with maturities less than 90 days totaling of $78.202 million (December 31, 2018 - $14.678 million).
4.Property and equipment:
5.Right of-use assets, operating leases:
6.Investments:
Investments consisted of the following as of December 31, 2019 and December 31, 2018:
7.Fair value measurements and financial instruments:
The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value.
Level 1 - inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2 - inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data or other means; and
Level 3 - inputs are unobservable (supported by little or no market activity).
The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs.
The following table presents the Company’s assets that are measured at fair value on a recurring basis for the periods presented:
8.Accrued liabilities:
Accrued liabilities as of December 31, 2019 and December 31, 2018 consisted of the following:
9.Lease liability
Aptose leases office space and lab space in San Diego, California. The lease for the office space expires on March 31, 2023 and can be extended for an additional 5 year period. The lease for our lab space expired on February 29, 2019, and on February 18, 2019 was renewed until February 28, 2022. We lease office space in Toronto, Ontario, Canada and the lease for this location expires on June 30, 2023 with an option to renew for another 5-year period. The Company has not included any extension periods in calculating its right-to-use assets and lease liabilities. The Company also enters into leases for small office equipment.
Minimum payments, undiscounted, under our operating leases are as follows:
To calculate the lease liability, the lease payments in the table above were discounted over the remaining term of the leases using the Company’s incremental borrowing rate as at January 1, 2019 for existing leases at the time of adopting the Topic 842, and for new leases after the date adoption, as at the date of the execution date of the new lease. The following table presents the weighted average remaining term of the leases and the weighted average discount rate:
Right-of-use assets obtained in exchange for new operating lease liabilities are as follows:
Operating lease costs and operating cash flows from our operating leases are as follows:
Comparable figures are not presented as the Company adopted the new standard using the alternative transition method, which permits a company to use its effective date as the date of initial application without restating comparative period financial statements.

The effect of any potential exercise of the Company’s stock options outstanding during the year has been excluded from the calculation of diluted loss per common share as it would be anti-dilutive.
11.Stock-based compensation:
(a)Stock options
Under the Company’s stock option plan, options, rights and other entitlements may be granted to directors, officers, employees and consultants of the Company to purchase up to a maximum of 17.5% of the total number of outstanding common shares, estimated at 13.3 million options, rights and other entitlements as at December 31, 2019. Options are granted at the fair market value of the common shares on the closing trading price of the Company’s stock on the day prior to the grant if the grant is made during the trading day or the closing trading price on the day of grant if the grant is issued after markets have closed. Options vest at various rates (immediate to four years) and have a term of 10 years.
Stock option transactions for the years ended December 31, 2018 and 2019 are summarized as follows:
Aggregate intrinsic value represents the excess of the value of the closing stock price on the previous trading day of the respective balance sheet dates over the exercise price of the stock options. Total intrinsic value of options exercised was $259 thousand for 2019 (2018 - $255 thousand).
As of December 31, 2019, there was $1.38 million of total unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over an estimated weighted-average period of 1.77 years.
The following table presents the weighted average assumptions that were used in the Black-Scholes option pricing model to determine the fair value of stock options granted during the year, and the resultant weighted average fair values:
The Company uses historical data to estimate the expected dividend yield and expected volatility of its common shares in determining the fair value of stock options. The expected life of the options represents the estimated length of time the options are expected to remain outstanding.
Stock options granted by the Company during the year ended December 31, 2019, vest 50% after one year and 16.67% on each of the next three anniversaries, except for 160,000 options which vest 50% after one year and 25% on each of the next two anniversaries and 335,000 options which vest 100% after one year.
Stock options granted by the Company during the year ended December 30, 2018 vest 50% after one year and 16.67% on each of the next three anniversaries, except for 166,000 options which vest 50% after one year and 25% on each of the next two anniversaries and 850,000 options which vested immediately on the grant date.
(b)Restricted share units
The Company has a stock incentive plan (SIP) pursuant to which the Board may grant stock-based awards comprised of restricted stock units or dividend equivalents to employees, officers, consultants, independent contractors, advisors and non-employee directors of the Company. Each restricted unit is automatically redeemed for one common share of the Company upon vesting. The following table presents the activity under the SIP plan for the year ended December 31, 2019 and 2018 the units outstanding.
On June 3, 2019, the Company granted 80,000 restricted share units (RSUs), 40,000 restricted share units of which have a vesting term of three months and the balance having a vesting term of one year. On September 3, 2019, 50% of these restricted share units were vested and were redeemed for 40,000 common shares.
On July 13, 2018, the Company granted 150,000 restricted share units with a vesting term of three months.
The grant date fair value of the June 3, 2019 RSUs and July 13, 2018 were respectively determined as the closing value of the common shares of the Company on the Nasdaq Stock Market on the date prior to the date of grant.
(c)Share-based payment expense
The Company recorded share-based payment expense related to stock options and RSUs as follows:
12.Related party transactions:
The Company uses Moores Cancer Center at the University of California San Diego (UCSD) to provide pharmacology lab services to the Company. Dr. Stephen Howell is the Acting Chief Medical Officer of Aptose and is also a Professor of Medicine at UCSD and oversees the laboratory work. The work is completed under the terms of research services agreements executed in March 2015 and has been extended annually. In March 2019, the Board approved an extension of this agreement for twelve months for services up to $300,000. These transactions are in the normal course of business and are measured at the amount of consideration established and agreed to by the related parties.
During the year ended December 31, 2019, the Company recorded $223 thousand (2018 - $279 thousand) in research and development expenses related to the agreement.
13.Collaborative agreements:
The Company enters into research, development and license agreements in the ordinary course of business where the Company receives research services and rights to proprietary technologies. Milestone and royalty payments that may become due under various agreements are dependent on, among other factors, clinical trials, regulatory approvals and ultimately the successful development of a new drug, the outcome and timing of which is uncertain.
Under the Company’s license agreement with CrystalGenomics for rights to CG-806, in all territories outside of the Republic of Korea and China, the Company has obligations for development milestones of $16 million related to the initiation of Phase 2 and pivotal clinical trials, and regulatory milestones totaling $44 million. The Company also has an obligation to pay royalty payments on sales of commercialized product. The timing of any milestone or royalty payments that may become due is not yet determinable.
On June 13, 2018, the Company entered into a license agreement with CrystalGenomics to gain an exclusive license to CG-806 in China. The Company has potential future obligations of development milestones of $6 million related to approval of an Investigational New Drug (“IND”) and to the initiation of Phase 2 and pivotal clinical trials, and regulatory milestones totaling $20 million. The Company also has an obligation to pay sales milestones and royalty payments on sales of commercialized product. The timing or likelihood of any milestone or royalty payments that may become due is not yet determinable.
On March 7, 2018, we entered into an exclusive global license agreement with Ohm Oncology (OHM), for the development, manufacture and commercialization of APL-581, as well as related molecules from our dual bromodomain and extra-terminal domain motif (BET) protein and kinase inhibitor program. Under the agreement, we will retain reacquisition rights to certain molecules, while OHM/LALS will have the rights to develop and sublicense all other molecules. We have received two nominal upfront cash payments and are eligible to receive up to $125 million of additional payments based on the achievement of certain development, regulatory and sales milestones, as well as significant royalties on future sales generated from the program, if any.
14.Income taxes:
(a)Recent tax legislation
In December 2017 the U.S. government enacted comprehensive tax legislation, the Tax Cuts and Jobs Act (the "Tax Act"), which significantly revises the U.S. tax code, generally effective January 1, 2018, by lowering the U.S. federal corporate income tax rate from 35% to 21%, implementing a territorial tax system and setting limitations on the deductibility of certain costs (e.g. Interest expenses) among other things. As a Canadian entity, we generally would be classified as a foreign entity (and, therefore, a non-U.S. tax resident) under general rules of U.S. federal income taxation. However, we have a branch and U.S. subsidiary subject to U.S. federal income taxation. The Tax Act has impacted our consolidated results of operations during 2017 and 2018, and is expected to continue to impact our consolidated results of operations in future periods. The ultimate impact of the Tax Act on our effective tax rate in future periods will depend on interpretations and regulatory changes from the Internal Revenue.
(b)Income taxes
For the years ended December 31, 2018 and 2019, the total comprehensive loss is as follows:
(c)Tax rate reconciliation
Major items causing the Company’s income tax rate to differ from the statutory rate of approximately 26.5% (December 31, 2018 - 26.5%) are as follows:
(d)Significant components of deferred taxes
The tax effects of temporary differences that give rise to significant portions of the unrecognized deferred tax assets are presented below:
The valuation allowance at December 31, 2019 was primarily related to net operating loss carryforwards that, in the judgment of management, are not more-likely than-not to be realized. In assessing the realizability of deferred tax assets, management considers whether it is more-likely than-not that all or some portion of the deferred assets will not be realized. This ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which those deductible temporary difference become deductible. Based on the history of losses and projections for future taxable income, management believes that it is not more-likely than-not that the Company will realize the benefits of these deductible temporary differences (e.g. deferred tax assets).
The Company has undeducted research and development expenditures, totaling $18.958 million that can be carried forward indefinitely. The Company also has Canadian non-refundable federal and provincial investment tax credits of approximately $4.113 million which are available to reduce future federal taxes payable and begin to expire in 2020, as well as non-refundable US research and development tax credits of approximately $0.557 million which are available to reduce future US taxes payable and begin to expire in 2038.
In addition, the Company has Canadian non-capital loss carryforwards of $97.127 million. To the extent that the non-capital loss carryforwards are not used, they begin to expire in 2026. The Company also has US non-capital loss carryforward of $0.586 million, To the extent that the non-capital loss carryforwards are not used, they begin to expire in 2034.
The Company files income tax returns with Canada and its provinces and territories. Generally we are subject to routine examinations by the Canada Revenue Agency ("CRA"). Income tax returns filed with various provincial jurisdictions are generally open to examination for periods of four to five years subsequent to the filing of the respective return.
The Company also files income tax returns for our U.S. operations and subsidiary with the U.S. federal and state tax jurisdictions. Generally, we are subject to routine examination by taxing authorities in the U.S. jurisdictions. There are presently no examination of our U.S. federal and U.S. state returns. We believe that our tax positions comply with the applicable tax law.
