Beginning June 19, NLM’s ClinicalTrials.gov resource will undergo a series of changes focused on improving the ability to search, display, and review information about clinical research studies registered with the site, resulting in a transition to the design and features available on the current version of the beta site. Additional designs and features will be evaluated on a new version of the beta site over the next few months. Changes will be introduced on ClinicalTrials.gov as they are ready, following testing and validation. It is anticipated that the most significant set of changes will be available on ClinicalTrials.gov in September 2017. An article highlighting these efforts is available in the NLM Technical Bulletin.
