RGH-706 as a Potential Therapeutic for PWS

Study Purpose

KITE PWS is a Phase 2 study to investigate the effects of RGH-706 in people with Prader-Willi Syndrome.  This study is seeking people aged 17 years and older with Prader-Willi syndrome for participation and will evaluate an experimental oral drug that may help to reduce appetite. The study lasts 5-6 months and requires about 8 study visits.

The purpose of this study is to learn more about an experimental drug called RGH-706. RGH-706 is an experimental oral drug that blocks melanin-concentrating hormone (MCH), which is a key part of the brain’s food-seeking mechanism. When this hormone attaches to specific receptors in the brain (i.e., proteins on the outside of brain cells), it increases the desire to eat. RGH-706 may help to block this hormone and reduce appetite.

The study drug, clinic visits, and study-related procedures are provided at no cost. Participants and caregivers may also receive reimbursement for travel and meals.
