A Focus on the Patient


The Prader-Willi Syndrome Clinical Trials Consortium is committed to engaging the PWS community and incorporating the patient perspective into the development of new therapies for PWS.  We believe the voice of the patient community is critical to understanding the unmet medical needs of this population, establishing priorities and value assessments, and framing the benefit-risk analysis of new drugs. A dynamic dialog between all stakeholders is essential to this process.


Active Projects


The Impact of PWS Symptoms on Caregivers

This survey of more than 200 parents and caregivers of individuals with PWS is a longitudinal study (0 and 6 months) to examine whether the caregiver`s burden levels can be incorporated in clinical trials as a relevant proxy measure indicative of the treatment outcomes of their child. Several questionnaires are administered to caregivers to assess the degree of hyperphagia of their child, the level of caregiver burden, the severity of symptoms and tasks caregivers are performing, and the impact of PWS on their quality of life.

Completed Projects

Measuring Caregiver Perspective of Unmet Clinical Needs for PWS​

A national online survey of caregivers that helped identify caregiver priorities for potential treatment and quantified caregiver preferences for the benefits and risks of treating PWS. An analysis will be published soon.
