Your Voice Will Make a Difference!

Prader-Willi Syndrome’s First Externally Led Patient-Focused Drug Development Meeting

Thank you to everyone who shared their voice in-person and virtually at the FDA Externally-Led Patient-Focused Drug Development Meeting. Your time and commitment to our loved ones living with PWS is truly incredible. A recording of the EL-PFDD meeting will be available at the end of July. As for next steps, we are working to build a "Voice of the Patient Report" based off the testimonials shared both during the EL-PFDD, and those collected on our website. You can learn more by scrolling below.

During the EL-PFDD meeting, we used a survey to collect critical patient information from the PWS community. This information will be used to assist the FDA in determining our patient experiences while evaluating therapies to treat different symptoms of PWS and will be published data in our Voice of the Patient Report. You DID NOT have to attend or participate in the EL-PFDD to take this survey and it is imperative that we capture as much data as possible for the FDA. Don’t delay, fill out the survey today.

Share Your Story

Ahead of the event, we are collecting testimonials from our PWS community. You can share your personal story, the struggles your family and loved one living with the syndrome have faced, or anything else you want others to consider. These testimonials will be included in our Voice of the Patient Report, which becomes published papers.

This will allow pharmaceutical companies access to the report so they can develop protocols that best fit our community's needs. Meaning, with this report, WE can help with the development of drugs to help our entire community.


This meeting provides an opportunity for patients, caregivers, and advocates to share their perspectives and experiences with the FDA and drug developers. By attending this meeting, you can make your voice heard and help shape the development of new treatments and therapies for Prader-Willi syndrome. Together, we can work towards improving the lives of those affected by this rare and complex genetic disorder.

This EL-PFDD meeting is designed to engage people living with PWS and their caregivers to elicit their real-life experiences including impact on quality of life and gaps in the current standard of care. With this information, the goal is to enable the FDA and other stakeholders to knowledgeably review and approve future therapies that addresses the needs of the PWS community.

We have two requests!  First, please avoid mentioning any specific drugs or trials. You can talk about treatment generally or about your trial experience but avoid mentioning any companies or brand names. Second, we ask that you keep your comments short. We anticipate having close to 500 people participating either in person or virtually, and we want to hear from as many people as possible.

PWSA is collecting testimonials from the community online before, during and after the EL-PFDD meeting: The testimonials may be included in the Voice of the Patient Report, which becomes a published public online report.

The images and quotes you provide may be included in the Externally-Led Patient-Focused Drug Development meeting, in the Voice of the Patient Report, or in other associated documents.

We will write the Voice of the Patient Report. This will be sent to the FDA and will be used to help in their decisions to approval potential treatments for PWS. The Voice of the Patient Report will be publicly posted on PWSA | USA’s website
