Clinical Trials Recruiting in Australia

Clinical trials tell us if a new therapy is safe and if it will help make life with PWS better.

The faster a clinical trial is completed, the sooner we know if the therapy works.   You can help by taking part in clinical trials and registries.  Your doctor and the study coordinator can help you decide if a trial is a good fit for you and your family.

Disclosure: PWFRA does not endorse or recommend any specific study, we aim to provide information about trials that people with PWS living in Australia can participate in.
