PWS Advocacy Coalition Submits Petition to FDA for Priority Review of DCCR NDA

On Friday, August 2, 2024, the PWS Advocacy Coalition submitted a petition to the U.S. Food and Drug Administration (FDA), requesting the filing and priority review of the New Drug Application (NDA) for Soleno Therapeutics’ drug, DCCR. The petition, signed by 14,271 members of the PWS community, was sent to FDA officials Dr. Tiffany Farchione (Psych Division Director), Dr. Teresa Buracchio (Office of Neuroscience Director), Dr. Peter Stein (Office of New Drugs Director), and Dr. Patrizia Cavazzoni (CDER Director).

The full petition, along with more than 100 pages of comments from the PWS community, is available via the button below. These comments provide compelling patient voices for the FDA to consider. While we anticipate the FDA will acknowledge the petition’s submission, we do not expect them to comment on it publicly due to their rules classifying the review of the DCCR NDA as “commercial, confidential information.”

This is a tremendous accomplishment, and everyone in the PWS community should feel very proud! We will share updates and details about the FDA’s review and decision regarding DCCR’s NDA as they become available.

About DCCR (Diazoxide Choline) Extended-Release Tablets

DCCR is a novel, proprietary extended-release dosage form containing diazoxide choline, the crystalline salt of diazoxide and is administered once-daily. The parent molecule, diazoxide, has been used for decades in thousands of individuals in a few rare diseases in neonates, infants, children and adults, but is not approved for use in PWS. Soleno conceived of and established extensive patent protection for the therapeutic use of diazoxide, diazoxide choline and DCCR in individuals 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 individuals with PWS. In the PWS Phase 3 clinical development program, 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. Diazoxide choline has received Orphan Drug Designation for the treatment of PWS in the U.S. and E.U., and Fast Track and Breakthrough Designations in the U.S.
