The U.S. Food and Drug Administration (FDA) has approved Soleno Therapeutics’ VYKAT XR (diazoxide choline) extended-release tablets, previously referred to as DCCR, for the treatment of hyperphagia in adults and children 4 years of age and older with Prader-Willi syndrome (PWS).
“The approval of VYKAT XR is a significant milestone for Soleno and, most importantly, for the PWS community who have had no options to treat the most disruptive aspect of this disease,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno.
“We are deeply grateful to the many individuals with PWS, their caregivers and clinical sites who participated in our trials, the advocacy groups, including FPWR and PWSA | USA, the advocates who have tirelessly supported the approval of VYKAT XR, the FDA for a collaborative review process, and our employees who have been committed to delivering VYKAT XR to those with PWS.”
Efficacy was established during the 16-week randomized withdrawal study period of Study 2-RWP (Study C602-RWP), a Phase 3 multi-center, randomized, double-blind, placebo-controlled trial. Individuals randomized to switch to placebo demonstrated a statistically significant worsening of hyperphagia compared with individuals who remained on VYKAT XR. Prior to participating in the randomized withdrawal period, all individuals received double-blind and/or open-label VYKAT XR for a mean duration of 3.3 years.
