FDA pushes sponsors to report missing trial results
The agency contacted more than 2,200 companies and researchers tied to more than 3,000 registered clinical trials that may be missing required results submissions.

The U.S. Food and Drug Administration has reminded more than 2,200 medical product companies and researchers to submit required clinical trial results information to ClinicalTrials.gov.
Messages were sent March 30 in connection with more than 3,000 registered clinical trials. FDA said the trials either do not appear to have submitted required results information or may not have completed the National Library of Medicine’s quality-control review process.
An internal FDA analysis found that 29.6% of studies highly likely to fall under mandatory reporting requirements had no results information submitted to ClinicalTrials.gov.
Mandatory reporting generally applies to interventional studies with a U.S. nexus and an FDA-regulated product that are past the results-reporting deadline. Phase 1 studies and device feasibility studies are excluded from the set described by FDA.
Certain sponsors and researchers must submit clinical trial results information to ClinicalTrials.gov 1 year after trial completion. FDA said missing negative trial results can create publication bias and distort the public record on medical product safety and efficacy.
“Too many clinical trial sponsors and researchers are failing to report their results, leaving important information unavailable to clinicians and other researchers,” FDA Commissioner Marty Makary, MD, MPH, said in the announcement.
The March 30 messages seek voluntary compliance. FDA said it may also issue pre-notices of noncompliance and notices of noncompliance as part of risk-based compliance efforts.
