PRS Guided Tutorials
The PRS Guided Tutorials have new and updated content and features to make them more useful in response to feedback obtained through focus groups and survey responses over the past year. Enhancements include updated images and improved zoom functionality, additional study examples from materials developed for the behavioral sciences community, and revisions to the Introduction and tutorial content for added clarity and guidance. Two new sections have also been added: Quick Start Guides are designed to help users get the most from the tutorials, and the PDF Library has all of the tutorial content in a single place, readily available for download. Please note that audio narration has been removed.
The following update has been posted on ClinicalTrials.gov PRS test, expected to go live on ClinicalTrials.gov PRS on February 01, 2021:

The below update has been posted on What’s New section of ClinicalTrials.gov PRS Test, which will go live on July 30, 2020:
- pACT Results Submission Change
As a result of a recent Federal court decision, some studies determined to be probable applicable clinical trials (pACT) under the FDA Amendments Act (FDAAA) that previously showed “[Not FDAAA required]” for Results Expected dates in the PRS now show “[30 days after approval]” instead. Results Expected dates are shown on the Record Summary page and in the Planning Report. For more information on this change, see the Frequently Asked Questions on the ClinicalTrials.gov public website.

Provide Your Comments to the ClinicalTrials.gov Request for Information
The National Library of Medicine is requesting public comment to guide efforts to enhance and better support the users of ClinicalTrials.gov, particularly within the following topic areas: Website functionality, information submission processes, and use of data standards. For consideration, your responses must be received electronically by March 14, 2020 using the web-based form linked from the Request for Information.
ClinicalTrials.gov PRS posted following update on December 30, 2019:
Changes to Posting Procedures for Applicable Clinical Trials
Consistent with requirements under 42 CFR 11.52, NIH must post results information for applicable clinical trials (ACTs) on the public website within 30 days of submission, regardless of whether the quality control (QC) review process is complete. For more information, see the Final Rule (42 CFR Part 11) Information page.
As of midnight EST (05:00 UTC), January 1, 2020, initial results submissions for ACTs that do not meet QC criteria will be posted publicly on ClinicalTrials.gov along with the brief standardized major issues. For details on the new procedures see the ClinicalTrials.gov Webinar: Updated Quality Control and Posting Procedures.
Major Comments List
The complete list of ClinicalTrials.gov Major Comments (issues) that may be provided to the responsible party by National Library of Medicine staff during QC review is now available on the ClinicalTrials.gov public website. This list will be updated as major comments are added or retired from use.
Update on Review Time for Records with Results
Quality control review of all records with results is now taking less than 30 days, regardless of whether the study appears to be an applicable clinical trial under 42 CFR Part 11 or an NIH-funded study. Previously, applicable clinical trials and NIH-funded studies were prioritized for review to ensure they were reviewed in fewer than 30 days.
