Soleno Therapeutics, Inc. has revealed positive outcomes from the randomized withdrawal phase of Study C602, an extended treatment study of DCCR (Diazoxide Choline) Extended-Release tablets for Prader-Willi syndrome (PWS). The results, which showed a significant improvement in hyperphagia-related behaviors in the DCCR group compared to the placebo group, support Soleno's plan to submit a New Drug Application (NDA) to the FDA next year. DCCR holds Orphan Drug and Fast Track designations from the FDA for PWS treatment.
In the study, 77 patients previously on DCCR treatment for two to four years were randomized to receive either DCCR or a placebo for four months. The primary endpoint, hyperphagia-related behaviors, significantly improved in the DCCR group. Secondary endpoints, including overall illness severity and change in condition, also favored DCCR. No new safety concerns were identified during the study.
To give further information, Soleno held a public webcast this morning (September 26, 2023) to share results from the study. You can find the recording at https://viavid.webcasts.com/viewer/event.jsp?ei=1636507&tp_key=3ff132cae9.

About DCCR (Diazoxide Choline) Extended-Release Tablets
DCCR is a novel, proprietary extended-release dosage form containing the crystalline salt of diazoxide and is administered once-daily. The parent molecule, diazoxide, has been used for decades in thousands of patients in a few rare diseases in neonates, infants, children and adults, but has not been approved for use in PWS. Soleno conceived of and established extensive patent protection on the therapeutic use of diazoxide and DCCR in patients with PWS. The DCCR development program is supported by data from five completed Phase 1 clinical studies in healthy volunteers and three completed Phase 2 clinical studies, one of which was in PWS patients. In the PWS Phase 3 study, DCCR showed promise in addressing hyperphagia, the hallmark symptom of PWS, as well as several other symptoms such as aggressive/destructive behaviors, fat mass and other metabolic parameters.
