DCCR for the Treatment of Hyperphagia in PWS

Study Purpose

Soleno Therapeutics is conducting a Phase 3 study of DCCR to measure the efficacy of the DCCR for treating hyperphagia in PWS. The study seeks to enroll 105 patients with PWS ages 4 years and older. The study will be a 15 week, randomized, double-blind, placebo-controlled study of Diazoxide Choline Controlled-Release Tablet (DCCR) and will require a once-daily oral administration. The initial 15-week study will be followed by a 9-month extension during which time all patients will receive DCCR.

Protocol Update: A recent amendment to the study protocol now allows patients between 20kg and 130kg to enroll in the study, provided they meet all eligibility criteria. Individual study sites will be able to enroll patients in the new weight band (20-30kg) once the appropriate tablet strengths come available, which will likely be in the September timeframe. Patients who are interested in enrolling should contact their nearest study coordinator.
