ClinicalTrials.gov Modernization Effort: Beta Releases Now Available

From NLM Musings From the Mezzanine:

Earlier this year, we provided an update on NLM’s efforts to modernize ClinicalTrials.gov, the world’s largest publicly accessible database of privately and publicly funded clinical trials. NLM released a request for information, hosted public webinars, and adopted a user-centered design approach intended to help ensure that modernization is responsive to user needs.

These activities, together with input from the NLM Board of Regents Public Service Working Group on ClinicalTrials.gov Modernization, supported the development of beta versions of a new ClinicalTrials.gov website and components of the information submission system, also known as the Protocol Registration and Results System (PRS). The beta releases feature a modern look and feel and provide updated technology to support users.

NLM is pleased to announce the public availability of these beta releases, which present the first of many new features to come.


The goals of the beta releases of the ClinicalTrials.gov website and components of the PRS are to:

  • Introduce users to the new technology platforms and evaluate their real-world performance,
  • Provide foundational features that will be expanded over time,
  • Provide PRS users with improved functionality to manage their record portfolios and workflows, and
  • Collect user input to inform future development activities.


The modernization effort has implemented a responsive site design that better supports mobile device users and added information written in plain language. The current release focuses on basic features, with more features to be added over time based on user feedback.

The first beta ClinicalTrials.gov release includes:

  • Redesigned home page and search feature,
  • Search results page with updated filter functionality,
  • New study record design with improved record navigation and study location information displayed using a web-based mapping application, and
  • Informational content presented in plain language such as Background and Learn About Studies webpages.
