Release Details

REDWOOD CITY, Calif., May 14, 2018 (GLOBE NEWSWIRE) -- Soleno Therapeutics, Inc. (“Soleno”) (NASDAQ:SLNO), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of rare diseases, today announced that it has initiated its multi-center Phase III clinical trial of Diazoxide Choline Controlled-Release (“DCCR”) for the treatment of Prader-Willi Syndrome (“PWS”). Seattle Children’s Hospital is the first site to be activated and Parisa Salehi, M.D., is the Principal Investigator for the trial at this site.

“Prader-Willi Syndrome leads to hyperphagia that can cause life-threatening obesity if left uncontrolled,” said Dr. Salehi. “This excessive hunger can cause significant harm to the lives of these individuals and their families. There is a lack of effective medical therapy targeting hunger in this population, and such a drug would be life-altering. Based on the data generated to date, DCCR has the potential to address this treatment void. We look forward to further evaluating DCCR in this important Phase III trial.”

“The initiation of the Phase III clinical trial of DCCR for the treatment of PWS represents a significant milestone for Soleno,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno. “Importantly, following meetings with the U.S. Food and Drug Administration, we have alignment with the agency on the key aspects of the Phase III clinical trial. We look forward to working with our clinical trial sites and the PWS community to successfully complete the trial.”

The Phase III clinical trial is a multi-center, randomized, double-blind, placebo-controlled study for DCCR that will treat approximately 100 PWS patients at 10-15 sites in the U.S. This trial is anticipated to take approximately 9-12 months to complete.  DCCR has orphan designation for the treatment of PWS in the US and in the EU.

About PWS
The Prader-Willi Syndrome Association USA estimates that one in 12,000 to 15,000 people in the US have PWS. The hallmark symptom of this disorder is hyperphagia, a chronic feeling of insatiable hunger that severely diminishes the quality of life for PWS patients and their families.  Additional characteristics of PWS include behavioral problems, cognitive disabilities, low muscle tone, short stature (when not treated with growth hormone), the accumulation of excess body fat, developmental delays, and incomplete sexual development. Hyperphagia can lead to significant morbidities (e.g., stomach rupture, obesity, diabetes, cardiovascular disease) and mortality (e.g., choking, accidental death due to food seeking behavior). In a global survey conducted by the Foundation for Prader-Willi Research, 96.5% of respondents (parent and caregivers) rated hyperphagia as the most important or a very important symptom to be relieved by a new medicine. There are currently no approved therapies to treat the hyperphagia/appetite, metabolic, cognitive function, or behavioral aspects of the disorder. Diazoxide choline has received Orphan Drug Designation for the treatment of PWS in the U.S. and EU.

About Diazoxide Choline Controlled-Release Tablet
Diazoxide choline controlled-release tablet is a novel, proprietary extended-release, crystalline salt formulation of diazoxide, which 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 positive data from five completed Phase I clinical studies in various metabolic indications or in healthy volunteers and three completed Phase II clinical studies, one of which was in PWS patients.  In the PWS Phase II study, DCCR showed promise in addressing hyperphagia, the hallmark symptoms of PWS.

About Soleno Therapeutics, Inc.
Soleno is focused on the development and commercialization of novel therapeutics for the treatment of rare diseases.  The company is currently advancing its lead candidate, DCCR, a once-daily oral tablet for the treatment of PWS, into a Phase III clinical development program in early 2018.
