How to find and contact a clinical trial.
Start with a condition. Narrow by location. Confirm details directly with the research team.
1. Search for your disease or diagnosis
Use the condition name your healthcare professional provided. If you see few results, try a broader condition term or search ClinicalTrials.gov directly. This directory searches public registration records; it cannot promise a complete list of available research opportunities.
2. Narrow the locations and study characteristics
Start with U.S. studies or choose worldwide search. Use state and city filters to find published locations. Broad study age groups, study type, phase, and recruiting-location filters can make a long list easier to scan. These are study characteristics and do not determine your personal eligibility. A phase describes part of the research process; it is not a recommendation or a guarantee of benefit.
3. Confirm which location is recruiting
A study may be recruiting overall while some locations are closed or have not started recruiting. Check the location status and ask the team whether enrollment is currently open at the site you can attend.
4. Use the right contact number
The main contact field shows a phone explicitly published for the displayed location. When no local phone is supplied, Study details may list a central contact for the entire study. Central contacts can be in another country; check the country code before calling. We format published numbers, but do not verify that every number is reachable.
5. Ask practical questions before taking part
Ask the study team about eligibility, visit locations and frequency, travel, possible costs or reimbursement, study procedures, and how to discuss participation with your healthcare professional. Keep your medical information for the study team’s own evaluation process; do not send medical records to researchcontact.com support.
