Release Details

REDWOOD CITY, Calif., Nov. 10, 2021 (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 three and nine months ended September 30, 2021.

“The recently announced top-line results from Soleno’s ongoing open-label extension study evaluating DCCR for the treatment of Prader-Willi syndrome (PWS), and the comparison of these data to matched subjects from the PATH for PWS (PfPWS) natural history study, highlight the compelling potential of this promising therapy in addressing the myriad physical and behavioral challenges faced by PWS patients and families,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “We have submitted these collective results to the U.S. Food and Drug Administration (FDA) as part of an ongoing discussion with the agency regarding the clinical data necessary to support the submission of a New Drug Application (NDA) to market DCCR for the treatment of PWS. We remain firmly committed to obtaining regulatory approval for DCCR as a new treatment for people with PWS as quickly as possible.”

Third Quarter 2021 and Recent Corporate Highlights

• Submitted to the FDA top-line results from the company’s ongoing open-label extension study, C602, evaluating investigational, once-daily DCCR (Diazoxide Choline) Extended-Release tablets for patients with PWS and its comparison to data from the PfPWS, an ongoing study sponsored by the Foundation for Prader-Willi Research (FPWR) to advance the understanding of the natural history in individuals with PWS.
  • A total of 115 subjects were enrolled into C602, the extension study in PWS patients who completed DESTINY PWS, an international, multi-center, randomized, double-blind, placebo-controlled study of DCCR.
    • Key top-line results of Study C602
      • Hyperphagia: There was a progressive improvement in hyperphagia, the primary endpoint in the DESTINY PWS study, represented by a decrease in the HQ-CT total score, which was highly significant (p<0.0001) after receiving DCCR for 52 weeks.
      • PWS related behaviors: Behaviors related to PWS were measured using the PWS Profile Questionnaire (PWS-P). After 52 weeks, there were statistically significant improvements in all behavioral domains (all p<0.0001).
      • The safety profile of DCCR remains consistent with the known safety profile of diazoxide and the prior experience with DCCR. No serious, unexpected, related adverse events have occurred with DCCR in the program to date.
  • Key top-line results of Study C602 compared to matched subjects from PfPWS
    • Hyperphagia:  Statistically significant improvement with DCCR was seen compared with PfPWS subjects at 52 weeks (p<0.001).
    • PWS related behaviors: As with hyperphagia, statistically significant improvements with DCCR in C602 subjects compared with subjects in the PfPWS study were seen in all behavioral domains of the PWS-P at 52 weeks (p<0.003 for all).
• Presented the above data from C602 and the comparison to PfPWS at the FPWR Annual Scientific Conference.
• Presented a DCCR clinical program overview at the FPWR Annual Family Conference, Presentation can be viewed here.
• Participated in the Oppenheimer Fall Healthcare Life Sciences and MedTech Summit.
• Participated in the 2021 Cantor Virtual Global Healthcare Conference.
  

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.

Financial Results for Three and Nine Months Ended September 30, 2021

Research and development expenses for the three and nine months ended September 30, 2021, were $5.0 million and $17.7 million, compared to $4.8 million and $17.6 million for the same periods of 2020, respectively. The fluctuations in expenses were primarily due to the cadence of activities related to the DCCR development program.

General and administrative expenses for the three and nine months ended September 30, 2021, were $2.8 million and $8.2 million, compared to $2.3 million and $6.5 million for the same periods of 2020, respectively. The increases were primarily related to increased compensation costs due to headcount growth and increased stock-based compensation expense.

The change in the fair value of contingent consideration results from Soleno’s obligation to make cash payments to Essentialis stockholders upon the achievement of certain future commercial milestones associated with commercial sales of DCCR in accordance with the terms of the Essentialis merger agreement. The fair value was estimated to be approximately $12.9 million as of September 30, 2021, a $0.6 million increase from the estimate on June 30, 2021, and a $2.6 million increase from the estimate on December 31, 2020.

Total other income (expense) was $0.1 million in the three months ended September 30, 2021, compared to other expense of $0.7 million during the three months ended September 30, 2020, and consisted primarily of the change in the fair value of the company’s outstanding warrants.

Net loss for the three and nine months ended September 30, 2021, was $8.1 million and $28.1 million, or a net loss of $0.10 and $0.35 per basic and diluted share, compared to net loss of $8.5 million and $21.8 million, or $0.11 and $0.38 per basic and diluted share, for the same periods in 2020, respectively.

As of September 30, 2021, Soleno had cash and cash equivalents of approximately $28.2 million, as compared to $49.2 million as of December 31, 2020.

About PWS
The Prader-Willi Syndrome Association USA estimates that PWS occurs in one in every 15,000 live births in the U.S. 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., 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 % body composition 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, and Fast Track Designation in the U.S.
