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.

Recruiting
The default view starts with recruiting studies because those are usually the most actionable.
Current order
Recently updated
Within the current status filter, results are ordered by the selected sort option.
ClinicalTrials.gov exposes a structured Accepts Healthy Volunteers field, not a standardized compensation amount. Healthy volunteer does not automatically mean control group, low risk, or paid. This page is U.S.-wide unless you add a city or state filter yourself. If payment, reimbursement, screening pay, or tax handling matters, confirm it on the official record or directly with the study team.

Filter healthy volunteer studies

These controls stay within studies whose public record says they accept healthy volunteers. The default view starts with Recruiting studies, and location only changes when you add a city or state.
