24 Nov 2016 ‘We’ve been deceived’: Many clinical trial results are never published
About half of clinical trial results are never published, leaving valuable information unavailable.
Every year, thousands of Canadians sign up to participate in clinical trials, offering their bodies to further the development of important medical advances like new drugs or devices. But the results of many of those trials never see the light of day.
A new online tool aims to put pressure on some of the companies and institutions behind the problem. TrialsTracker maintains a list of all the trials registered on the world’s leading clinical trials database and tracks how many of them are updated with results.
Amid pharmaceutical companies and research bodies from around the world on ClinicalTrials.gov, maintained by the U.S. National Institutes of Health, nine Canadian universities and institutions rank in the top 100 organizations with the greatest proportion of registered trials without results.
