Updates to Clinicaltrials.gov FAQs and “How to Register Your Study Page”

Recently, the National Library of Medicine (NLM) released two updates to ClinicalTrials.gov Protocol Registration and Results System (PRS) resources. The first is an update to the FAQs to explain the good cause extension request deadlines for clinical trials that are prematurely terminated more than one year after the date of completion.

The How to Register Your Study page now includes additional information on registering expanded access records under the Considerations for Observational Studies and Expanded Access Records section along with additional information from the FDA and NIH websites.

Review both to make sure you are up-to-date with the latest information from Clinictrials.gov.
