Clinical studies--what are they?

Clinical research includes all research involving human participants. Clinical trials are clinical research studies that are evaluating the effects of a biomedical or behavioral intervention (drugs, biologics, devices, procedures, and strategies to change health behaviors, for example) on health-related outcomes (reduced blood pressure, cancer remission, depression management, for example).

Many new medicines and treatments are found to be helpful and safe in test tubes and in animals. They must also prove safe and effective in humans before doctors can prescribe them. This testing in humans is permitted only if that person volunteers for participation and understands the risks and benefits of taking part in the clinical trial. This informed consent to participate must be based on the volunteer's understanding of what is involved in the clinical trial, including potential risks and benefits. Volunteers may leave a clinical trial or clinical research study at any time.

This is a collection of all clinical research studies, including clinical trials, being conducted by the National Institutes of Health at the National Institutes of Health Clinical Center in Bethesda, Maryland. If you have any questions about participating in a clinical study here, please contact the Patient Recruitment Office, Phone: 1-800-411-1222, TTY 1-866-411-1010.
