FAQ

Questions ClinicalTrials.gov owners ask.

  • 01

    Do I need an API Key or registration?

    No. ClinicalTrials.gov is a fully public service maintained by the US National Library of Medicine. All data is accessible without any authentication.

  • 02

    What types of studies can I search for?

    The database covers interventional trials (testing drugs, devices, procedures), observational studies, and expanded access programs. You can search across all phases, from early Phase 1 research to post-market Phase 4 surveillance.

  • 03

    Is the trial recruiting status updated in real time?

    The data reflects what is currently published on the ClinicalTrials.gov database. Sponsors typically update the registry directly, so you will see the latest status logged in their system.
