Release Details

REDWOOD CITY, Calif., May 09, 2024 (GLOBE NEWSWIRE) -- Soleno Therapeutics, Inc. (Soleno) (NASDAQ: SLNO), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of rare diseases, today provided a corporate update, and reported financial results for the first quarter ended March 31, 2024.

First Quarter 2024 and Recent Corporate Highlights

• Closed on approximately $158.7 million underwritten public offering of 3,450,000 shares of common stock at a public offering price of $46.00 per share, which includes the exercise in full by the underwriters of their overallotment option to purchase additional shares.
• Granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration (FDA) for Diazoxide Choline Extended-Release (DCCR) for the treatment of adults and children ages four years and older with genetically confirmed Prader-Willi syndrome (PWS) who have hyperphagia.
• Planned submission of a New Drug Application (NDA) for DCCR in PWS remains on track for mid-2024.
• Published peer-reviewed paper featuring the comparison of results from the Company’s Phase 3 placebo-controlled study (C601) and open-label extension study (C602) evaluating DCCR in patients with PWS to data from the PATH for PWS (PATH) natural history study in the Journal of Neurodevelopmental Disorders. The article, entitled, Behavioral Changes in Patients with Prader-Willi Syndrome Receiving Diazoxide Choline Extended-Release Tablets Compared to the PATH for PWS Natural History Study showed there to be significant improvements in hyperphagia and other PWS-associated behaviors with DCCR compared with natural history, and can be found here.
• Strengthened leadership team with appointments of Meredith Manning, M.B.A. as Chief Commercial Officer, Dairine Dempsey, Ph.D. as Vice President, Europe and Lauren Budesheim, M.S. as Vice President of Human Resources.
  

“Soleno’s top priority remains NDA submission for DCCR in PWS,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “Receiving Breakthrough Therapy Designation from the FDA for DCCR was a significant milestone, and we are working diligently to ensure a timely NDA submission. In parallel, our commercial team has begun preparations for a potential commercial launch of DCCR. We believe DCCR has the potential to significantly improve the lives of people living with PWS, and, if approved, could be a foundational therapy in the treatment of PWS.”

Financial Results

Soleno’s current research and development efforts are primarily focused on advancing its lead product candidate, DCCR, for the treatment of PWS, through late-stage clinical development.

First Quarter Ended March 31, 2024 Financial Results

As of March 31, 2024, Soleno had $42.8 million of cash and cash equivalents, $106.8 million of short-term investments, and $8.8 million of long-term investments. In addition, in May 2024, the Company received $148.8 million in net proceeds from the Closing of a public offering, bringing pro forma cash reserves to a total of $307.2 million.

Research and development expense was $14.6 million for the three months ended March 31, 2024, compared to $5.3 million in the same period of 2023. The increase was primarily due to increased headcount cost, expenditures in support of our NDA submission and CMC project investment in preparation for commercial launch.

General and administrative expense was $8.5 million for the three months ended March 31, 2024, compared to $2.9 million in the same period of 2023. The increase was primarily related to higher stock-based compensation expense, higher costs because of an increase in headcount and higher professional and consulting expenses.

Soleno is obligated to make cash payments of up to a maximum of $21.2 million to the former Essentialis stockholders upon the achievement of certain commercial milestones associated with the future sales of DCCR in accordance with the terms of Soleno’s 2016 merger agreement with Essentialis. The fair value of the liability for the contingent consideration payable by the Company upon achieving two commercial sales milestones of $100 million and $200 million in revenue in future years was estimated to be $12.0 million as of March 31, 2024, a $0.4 million increase from the estimate as of December 31, 2023.

Total other income, net, was $2.1 million for the three months ended March 31, 2024, and $0.1 million in the same period of 2023. The increase was primarily due to an increase in interest income driven by higher cash and cash equivalents, short-term and long-term investments during the three months ended March 31, 2024, compared to the three months ended March 31, 2023.

Net loss was approximately $21.4 million, or $0.59 per basic and diluted share, for the quarter ended March 31, 2024, and $8.4 million, or $0.88 per basic and diluted share, in the same period of 2023.

About PWS
The Prader-Willi Syndrome Association USA estimates that PWS occurs in one in every 15,000 live births. The hallmark symptom of this disorder is hyperphagia, a chronic and life-threatening feeling of intense, persistent hunger, food pre-occupation, extreme drive to food seek and consume food that severely diminish the quality of life for patients with PWS 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., obesity, diabetes, cardiovascular disease) and mortality (e.g., stomach rupture, 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 and 92.9% rated body composition as either 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 DCCR (Diazoxide Choline) Extended-Release Tablets
DCCR is a novel, proprietary extended-release dosage form containing the crystalline salt of diazoxide and 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 for the therapeutic use of diazoxide, diazoxide choline and DCCR in patients 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 patients 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.
