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.
These results were retrieved from the live ClinicalTrials.gov registry. Filters and sort order apply to this result list.
Data is sourced from official ClinicalTrials.gov public API records. Always review the official ClinicalTrials.gov record for the latest information.
