On June 25, 2024, the modernized will become the singular website experience. This major milestone is part of NLM’s multi-year modernization effort, which has been guided by stakeholder engagement, input from the NLM Board of Regents Public Service Working Group, and a user-centered design approach.

Since 2019, we have provided updates on NLM’s progress in modernizing, the world’s largest clinical trial and results registry. The modernization effort has focused on delivering an improved user experience on an updated platform that will accommodate growth and enhance efficiency. In March 2023, to provide users with time to transition, we announced that the classic website will be retired in 2024.

Importantly, the retirement of the classic version of the website does not mark the end of this modernization. NLM will continue to enhance and update the modernized and release additional features such as functionality to browse studies by topic and expert search capabilities. NLM also continues to work on modernizing the Protocol Registration and Results System (PRS), the clinical trial information submission and management portal for An enhanced results information submission process is coming soon, and PRS Beta will become the new primary registration website later this summer.

Feedback plays an important role in assessing the impact of this modernization effort, and we encourage users to share their comments. Please use the feedback button on the modernized website to ensure that we hear from you.
