Healthy Volunteer Hub
Healthy volunteer clinical trials in the U.S.
This page focuses on public ClinicalTrials.gov records that explicitly say they accept healthy volunteers. It starts with recruiting studies by default, and it does not guess the visitor's location. Add a city or state only when you want location-specific results before checking the official study record.
The live registry is temporarily unavailable. These stored records may be incomplete or out of date. Check the official record for current status and contact information.
Data is sourced from official ClinicalTrials.gov public API records. Always review the official ClinicalTrials.gov record for the latest information.
