The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) supports basic and clinical research into many digestive disorders, including hepatitis A.
Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research. For information about current studies, visit www.ClinicalTrials.gov.
