Finding a Clinical Trial
Around the Nation and Worldwide
NIH conducts clinical research trials for many diseases and conditions, including cancer, Alzheimer’s disease, allergy and infectious diseases, and neurological disorders. To search for other diseases and conditions, you can visit ClinicalTrials.gov.
ClinicalTrials.gov [ How to Use Search ]
This is a searchable registry and results database of federally and privately supported clinical trials conducted in the United States and around the world. ClinicalTrials.gov gives you information about a trial's purpose, who may participate, locations, and phone numbers for more details. This information should be used in conjunction with advice from health care professionals.
Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read the disclaimer on ClinicalTrials.gov for details.
Before participating in a study, talk to your health care provider and learn about the risks and potential benefits.

Visitors can search by diagnosis, sign, symptom or other key words.
Join a National Registry of Research Volunteers
This is an NIH-funded initiative to connect 1) people who are trying to find research studies, and 2) researchers seeking people to participate in their studies. It is a free, secure registry to make it easier for the public to volunteer and to become involved in clinical research studies that contribute to improved health in the future.
