Clinical Trials Overview

Why Participate?

Participants in clinical trials are:

  • Seen by a team of expert doctors, nurses, technicians, and support staff
  • Often the first to receive promising new treatments before they become available in the community
  • Helping others with the same disease—both today and in the future

Participants in clinical trials can:

  • Play a more active role in their own health care
  • Potentially gain access to new research treatments before they are widely available
  • Help others by contributing to greater medical knowledge
