REDWOOD CITY, Calif., Oct. 11, 2017 (GLOBE NEWSWIRE) — Soleno Therapeutics, Inc. (NASDAQ:SLNO), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of rare diseases, announced today the issuance of a new patent (9,782,416) from the U.S. Patent and Trademark Office related to the use of pharmaceutical formulations of diazoxide to treat hyperphagia in a subject with Prader-Willi syndrome (PWS). PWS is a rare and complex genetic neurobehavioral/metabolic disorder affecting appetite, growth, metabolism, cognitive function, and behavior.
“This patent further strengthens our intellectual property portfolio in the treatment of PWS,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “Importantly, it covers the treatment of hyperphagia, one of the highest priority unmet needs in PWS, and the primary endpoint of our planned Phase III study of our lead product candidate, DCCR. Moving forward, we intend to continue pursuing opportunities to protect and expand our intellectual property estate.”
Soleno expects to initiate the Phase III clinical development program of Diazoxide Choline Controlled Release Tablet (DCCR) in PWS by the end of 2017. The Company is currently finalizing the design of a randomized, double-blind placebo-controlled study that will treat approximately 100 patients. This study is anticipated to take approximately 9-12 months to complete. DCCR has Orphan Designation for the treatment of PWS in the U.S.
PWS is a rare and complex genetic neurobehavioral/metabolic disorder affecting appetite, growth, metabolism, cognitive function and behavior. The committee on genetics of the American Academy of Pediatrics states PWS affects both genders equally and occurs in people from all geographic regions: its estimated incidence is one in 15,000 to 25,000 live births. This disorder is typically characterized by hyperphagia, a chronic feeling of insatiable hunger, 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 (i.e., stomach rupture, obesity, diabetes, cardiovascular disease) and mortality (i.e., choking, accidental death due to food seeking behavior, etc.). In a global survey conducted by the Foundation for Prader-Willi Research, 96.5% of respondents (parent and caregivers) rated hyperphagia, which is the unrelenting hunger that severely diminishes the quality of life for patients and their families, 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.
About Diazoxide Choline Controlled-Release Tablet
Diazoxide choline controlled-release tablet is a novel, proprietary controlled-release, crystalline salt formulation of diazoxide, which is administered once-daily. The parent molecule, diazoxide, as an oral suspension, has been used for decades in thousands of patients in a few rare diseases in neonates, children and/or adults, but not in PWS. Essentialis conceived of and is pursuing an extensive patent portfolio relating to various aspects of the therapeutic use of diazoxide and DCCR in patients with PWS. The DCCR development program is supported by positive data from two completed Phase II clinical studies and six completed Phase I clinical studies in various metabolic indications, as well as a pilot study in PWS patients. In the PWS pilot study, DCCR showed promise in addressing the hallmark symptoms of PWS, most notably hyperphagia. DCCR has received Orphan Drug Designation from the US FDA for the treatment of PWS.
About Soleno Therapeutics, Inc.
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 at the end of 2017. Soleno, through its wholly owned subsidiary, Capnia, Inc., continues to market Capnia’s innovative medical devices, including the CoSense® End-Tidal Carbon Monoxide (ETCO) monitor, which measures ETCO and is used by hospitals to detect hemolysis in newborns. It is expected that CoSense will be monetized and will not be a focus for the company in the long term.
