Clinical Trials at the NIH
The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the nation’s medical research agency—making important discoveries that improve health and save lives. Thanks in large part to NIH-funded medical research, Americans today are living longer and healthier. In recent years, nationwide rates of new diagnoses and deaths from all cancers combined have fallen significantly. It's your involvement that helps researchers ultimately uncover better ways to treat, prevent, diagnose and understand human disease. Learn more about NIH Clinical Research Trials and You.
