Volunteers, Studies & Investigators

The courage to cure.

At the heart of every medicine in your cabinet are thousands of volunteers just like you who have taken part in special research studies called clinical trials. In fact, when you decide to take part in a clinical trial, you are helping advance modern medicine itself, potentially improving or even saving lives for decades to come.

Why participate?

As a participant in a clinical trial, you are making a substantial contribution to finding new and better ways to help other patients in the future. In addition, you may benefit from a new and better investigational medication that is not currently available.



About clinical trials

The development of an innovative new treatment is often a lengthy and costly process - all treatments will have previously undergone rigorous testing in the laboratory before progressing onto testing in humans. A clinical trial is the term used to describe the testing of a new treatment or medical device.
