Clinical Trials Pave The Way For PWS Treatments

PWS clinical trials are taking place around the world to help us understand Prader-Willi syndrome and investigate new treatments; please see the list below for active and pending clinical trials. Click on the link at the left of each column for additional information about each of the clinical trials that are active or are about to start. We encourage you to learn more about these clinical trials, talk with your physician about potential risks and benefits, and ask questions to help you decide if enrolling in a clinical trial is right for you or your loved one with PWS.
