Several NEW PWS trial opportunities are now available. FPWR maintains the latest clinical trial information so that you can stay abreast of trial opportunities. Some trials require in-person visits while others can be completed remotely. Some trials are testing new drugs while others are intervention (non-drug) or natural history studies, like the PWS Weight Study described below.
FPWR does not endorse or recommend any specific study. Our goal is to provide information to members of the PWS community decide whether participation in a clinical trial is right for them and their loved one with PWS. Anyone considering participating in a clinical trial should discuss the matter with his or her physician.

Oxytocin and the Autonomic Nervous System in PWS (ages 13-30)
Patients ages 13-30 are needed to participate in a study aiming to understand the nature of the oxytocin abnormality in PWS. The study will be conducted over a 2 hour visit at either the University of Sydney in Camperdown, NSW or the Royal Children’s Hospital in Parkville, Victoria. Learn more >>
Eye Tracking - Developing Objective Biomarkers of Hyperphagia (ages 3 - 12)
This study requires a single in-person visit. Eye tracking technology will be used to measure how children process images of food vs. objects. The aim of this study to to determine if eye tracking can help us better understand and measure hyperphagia objectively. For this study, both children with PWS and neurotypically developing peers are needed, ages 3-12. This study is being done in collaboration with the team at Vanderbilt University. The study team will be visiting Chicago the end of July as well as is planning to visit Boston as well as the tri-state area this summer. If you are in those areas and interested in participating in the study, contact the team! Learn more >>
