SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry
entitled ``Drug-Drug Interaction Assessment for Therapeutic Proteins.''
With the continued market growth and increased clinical use of TPs, it
is important to understand the nature of and the potential for DDIs
with these products. This guidance supplements the final FDA guidances
for industry entitled ``In Vitro Drug Interaction Studies--Cytochrome
P450 Enzyme- and Transporter-Mediated Drug Interactions'' and
``Clinical Drug Interaction Studies--Cytochrome P450 Enzyme- and
Transporter-Mediated Drug Interactions'' (January 2020) by providing a
systematic, risk-based approach to determining the need for DDI studies
for TPs. This guidance discusses considerations for assessing DDIs for
TPs, including situations where determining the DDI potential of a TP
is warranted. The guidance also discusses various types of DDI
assessments, considerations for study design, and recommendations for
labeling.
    This draft guidance is being issued consistent with FDA's good
guidance practices regulation (21 CFR 10.115). The draft guidance, when
finalized, will represent the current thinking of FDA on ``Drug-Drug
Interaction Assessment for Therapeutic Proteins.'' It does not
establish any rights for any person and is not binding on FDA or the
public. You can use an alternative approach if it satisfies the
requirements of the applicable statutes and regulations.

II. Paperwork Reduction Act of 1995

    This draft guidance refers to previously approved FDA collections
of information. These collections of information are subject to review
by the Office of Management and Budget (OMB) under the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501-3521). The collections of
information for submissions of investigational new drug applications,
new drug applications, and biologic license applications in 21 CFR
parts 312, 314, and 601 have been approved under OMB control numbers
0910-0014, 0910-0001, and 0910-0338, respectively. In addition, the
submission of prescription drug labeling under 21 CFR 201.56 and 201.57
has been approved under OMB control number 0910-0572.

III. Electronic Access

    Persons with access to the internet may obtain the draft guidance
at either https://www.fda.gov/drugs/guidance-compliance-regulatory-information/guidances-drugs, https://www.fda.gov/vaccines-blood-biologics/guidance-compliance-regulatory-information-biologics/biologics-guidances, or https://www.regulations.gov.
