AllTrials
AllTrials (sometimes called All Trials or AllTrials.net) is a project advocating that clinical research adopt the principles of open research. The project summarizes itself as "All trials registered, all results reported": that is, all clinical trials should be listed in a clinical trials registry, and their results should always be shared as open data. At the center of the organisation is a petition signed by over 85,000 individuals and
599 organisations (as of August 2015):

Thousands of clinical trials have not reported their results; some have not even been registered. Information on what was done and what was found in these trials could be lost forever to doctors and researchers, leading to bad treatment decisions, missed opportunities for good medicine, and trials being repeated. All trials past and present should be registered, and the full methods and the results reported.
