December 19, 2018

Financing Led by Abingworth; Andrew Sinclair, Partner, to Join Soleno’s Board

Funding to Support Ongoing Phase III Clinical Program (DESTINY PWS) for DCCR in Prader-Willi Syndrome

REDWOOD CITY, Calif., Dec. 19, 2018 (GLOBE NEWSWIRE) -- Soleno Therapeutics, Inc. (NASDAQ: SLNO), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of rare diseases, today announced that it has entered into a definitive agreement with certain institutional and accredited investors to raise aggregate gross proceeds of approximately $16.5 million through the private placement of its equity securities (“PIPE”). The financing was led by Abingworth LLP, a leading transatlantic bioscience investment firm, and supported by certain of Soleno’s existing investors, including Oracle Investment Management and entities associated with Jack W. Schuler, as well as Ernest Mario, the Chairman of the company’s Board of Directors. In connection with this financing, Andrew Sinclair, a Partner at Abingworth, will join Soleno’s Board of Directors.

Soleno will sell 10,272,375 Units at $1.60625 per Unit. Each Unit consists of one share of Soleno’s Common Stock at a purchase price of $1.60, the closing price of the Common Stock on December 18, 2018, and one warrant to purchase 0.05 shares of Common Stock at a purchase price of $0.00625 per warrant, for gross proceeds of approximately $16.5 million. Each warrant has an exercise price of $2.00 per share. The warrants become exercisable on the six month anniversary of the closing of the PIPE and will have a term of five years.

Soleno intends to use the net proceeds from the offering to support the ongoing DESTINY Phase III program (“DESTINY PWS”) of Diazoxide Choline Controlled-Release (“DCCR”) in Prader-Willi syndrome (“PWS”), a rare and complex genetic neurobehavioral/metabolic disorder affecting appetite, growth, metabolism, cognitive function, and behavior, as well as general corporate purposes.

About PWSThe 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 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.For more information, please visit www.soleno.life.
