It’s time all clinical trial results are reported. Watch this video and change something.

Results from around half of clinical trials have never been published. 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. The contributions of the hundreds of thousands of patients who took part in those trials remain unused and unusable.

75,000 people and more than 450 organisations have joined the campaign for all trials past and present to be registered, and the full methods and the results reported. Public pressure is already changing regulations and getting past trials published in some countries. You and everyone you know can join it at and by sharing this video.

This video was made possible by the donations of 600 individuals and RCVS Knowledge.
