The International Consortium to Advance Clinical Trials for Prader-Willi Syndrome (PWS-CTC) was established in 2015 to encourage collaboration and leverage the expertise and perspective of stakeholders from industry, academia,  and patient organizations in a pre-competitive space in order to address the unmet scientific, technical, clinical and regulatory needs of clinical trials for PWS. 


The Consortium aims to develop outcome measures to assess treatment efficacy against hyperphagia and other behavioral challenges, as well as develop rigorous methods to incorporate the patient and caregiver perspectives into the benefit/risk assessment of new treatments.
