WHO Statement for Public Disclosure of Clinical Trial Results

June 2015

On 14 April 2015, the World Health Organization (WHO) updated its 2005 statement on the public disclosure of results from all interventional clinical trial.1,2

A paper outlining the rationale for the new position was also published online in the free-access journal PLoS Medicine.3

The new statement now defines timelines for reporting, including calls older but still unpublished trials, and outlines ways to improve the links between clinical trial registries and the published results. This includes reporting studies that produced negative or inconclusive results.

Similar demands are stated in the latest version of the Declaration of Helsinki.4-6

A paper published last year on large studies (>500 participants) registered on clinicaltrials.gov and completed by 2009, reported that 23% still had not published results after a median of 60 months since the studies ended.7

Although shorter timeframes are strongly encouraged, maximum reporting time frames include that:

  1. The main findings of clinical trials are to be submitted for publication in a peer reviewed journal within 12 months of study completion. They are to be published through an open access mechanism unless there is a specific reason why open access cannot be used, or otherwise made available publicly at most within 24 months of study completion.
  2. Key outcomes are to be made publicly available within 12 months of study completion by posting to the results section of the primary clinical trial registry.
  3. Unreported clinical trials conducted in the past are to be disclosed in a publicly available, free to access, searchable clinical trial registry. In addition, it is desirable that unreported clinical trials are published in a peer-reviewed journal.
  4. Publications should always include the trial ID number.
