When it comes to disclosing clinical trial data, some drug makers are still keeping secrets. A new study finds that 35 percent of all trial results for 15 drugs that were approved in 2012 by the Food and Drug Administration were not publicly disclosed. And nearly 30 percent of the trials conducted for those drugs failed to meet legal disclosure requirements.
The findings come amid growing clamor from academics and consumer groups to press drug and device makers to release trial data. If research is not published or reported in accessible registries, physicians and patients are prevented from having a complete picture of the risks and benefits of medicines.
