ClinicalTrials.gov is a registry and results information database of clinical research studies sponsored or funded by a broad range of organizations around the world. It is managed by the National Institutes of Health, an agency of the U.S. Department of Health and Human Services that funds biomedical and behavioral research, including clinical trials.

Information on ClinicalTrials.gov is provided by the sponsor or principal investigator of the clinical study, and posting to the site does not necessarily reflect endorsement by NIH. ClinicalTrials.gov does not independently verify the scientific validity or relevance of the submitted information beyond a limited quality control review for apparent errors, deficiencies, or inconsistencies.

Choosing to participate in a study is an important personal decision. We urge potential participants to discuss all options with their healthcare providers and other trusted advisors. To learn more about a specific study, contact the study research staff listed in the study record. For more information about participating in clinical studies, see Learn About Clinical Studies, which includes questions that you might want to ask before agreeing to participate in a study.

For more information about using the information on ClinicalTrials.gov, please also see Terms and Conditions.
