REDWOOD CITY, Calif., Oct. 02, 2019 (GLOBE NEWSWIRE) -- Soleno Therapeutics, Inc. (SLNO), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of rare diseases, today announced that the Data Safety Monitoring Board (DSMB) has, for the second time, recommended the continuation without modification of the Company’s Phase III trial in Prader-Willi Syndrome (PWS) patients, DESTINY PWS. The outcome of this second planned meeting was based on the review of data from more than 50% of patients enrolled and treated.
“We are pleased to again receive the DSMB’s recommendation to continue the Phase III trial as planned and without modification, which provides ongoing support of DCCR’s safety profile,” said Dr. Anish Bhatnagar, Chief Executive Officer of Soleno. “Enrollment in DESTINY PWS remains on track for the availability of top-line data in the first half of 2020.”
DESTINY PWS is a Phase III, randomized, double-blind, placebo-controlled study of once daily oral administration of DCCR versus placebo in approximately 100 patients with a confirmed diagnosis of PWS. The primary endpoint is change from baseline hyperphagia score at Week 13. Patients who complete DESTINY PWS have the option to enroll into C602, the open-label safety extension study.
The DSMB is a group of independent experts monitoring the safety of DESTINY PWS. The DSMB reviews safety information and can make recommendations to either continue the study without modification, modify the study or terminate the study due to safety concerns.
In July 2018, the U.S. Food and Drug Administration designated the investigation of DCCR for the treatment of PWS to be a Fast Track development program. Prior to this, diazoxide choline received orphan designation for the treatment of PWS in the U.S. and in the E.U.

The Prader-Willi Syndrome Association USA estimates that one in 12,000 to 15,000 people in the U.S. 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 E.U.
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 data from five completed Phase I clinical studies 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 symptom of PWS, as well as several other symptoms such as aggressive/destructive behaviors, fat mass and abnormal lipid profiles.
About Soleno Therapeutics, Inc.
Soleno is focused on the development and commercialization of novel therapeutics for the treatment of rare diseases. The company’s lead candidate, DCCR, a once-daily oral tablet for the treatment of PWS, is currently being evaluated in a Phase III clinical development program.
