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.

PRETEND Remote Play-Based intervention Study (ages 6 - 9) - COMING TO DC
A special call-out to PWS families in the Washington DC area! The Dimitropoulos Team is visiting the area this spring, and will be actively enrolling for the remaining spots in the PRETEND study. This study is focused on optimizing development in children with PWS and is recruiting families of children with PWS ages 6-9 years old. This study includes both direct play-based intervention for children over a remote video-conferencing platform to increase children's play skills, emotional regulation, and cognitive and behavioral flexibility. The study takes 8 weeks, and only requires TWO in person visits in your area - once at the beginning of the study and once at the end. We are also recruiting families of children with PWS ages 3-12, as well as siblings, for a one-time visit eye-tracking study. For questions on either study, you can contact the research team via email or by phone at 216-368-0112.
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.
