REDWOOD CITY, Calif., Aug. 10, 2022 (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 six months ended June 30, 2022.
Second Quarter 2022 and Recent Corporate Highlights
- U.S. Food and Drug Administration (FDA) acknowledged that data from a proposed randomized withdrawal phase of Study C602 would have the potential to address its concerns regarding the adequacy of the overall efficacy data supportive of a New Drug Application (NDA) submission for DCCR. Study C602 is an ongoing open-label extension study comprised of patients who completed DESTINY PWS, an international, multi-center, randomized, double-blind, placebo-controlled study of DCCR.
- The randomized withdrawal phase would consist only of participants currently enrolled in Study C602 and not include any new patients.
- The Company continues to work collaboratively with the FDA to finalize specific details of the study design and plans to initiate the randomized withdrawal period in the current quarter, with top-line data expected in the first quarter of 2023.
- Results from the analysis of caregiver interviews conducted after at least 12 months of investigational, open-label DCCR treatment showing positive changes across food- and non-food-related behaviors, as well as daily life, presented at the 11th International Prader-Willi Syndrome Organisation (IPWSO) Conference.
- Long-term clinical data showing improvement in metabolic parameters and body composition following treatment with DCCR tablets in patients with PWS presented at ENDO 2022.
- Data on the ongoing safety and efficacy of DCCR in PWS patients at presented the 2022 European Congress of Endocrinology.
“We are pleased to report on a productive period, underscored by positive feedback received from the FDA regarding the planned randomized withdrawal phase of Study C602 that has the potential to support an NDA submission for DCCR ,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “Our recent presentations at scientific conferences continue to emphasize the significant potential of DCCR to be an effective and safe therapy for patients and families struggling to manage the symptoms 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. Cash as the end of June 30, 2022 was $24.1million which the Company believes is sufficient to fund operations at least through top line-data expected in first quarter 2023.
Second Quarter Ended June 30, 2022 Financial Results
Research and development expenses for the three and six months ended June 30, 2022, were $3.7 million and $7.7 million, compared to $5.6 million and $12.8 million for the same periods of 2021. Soleno’s research and development spending continues to fluctuate depending upon the state of its clinical programs and the timing of CMC costs and other projects necessary to support the submission of an NDA.
General and administrative expenses for the three and six months ended June 30, 2022, were $2.5 million and $5.1 million, compared to $2.5 million and $5.4 million for the same periods of 2021. The decrease was primarily due to a reduction in stock-based compensation.
The change in fair value of contingent consideration is a result of Soleno remeasuring at the end of each reporting period its obligation to make cash payments to Essentialis stockholders upon the achievement of certain future commercial milestones associated with the acquisition of DCCR in accordance with the terms of the Essentialis merger agreement. The fair value was estimated to be approximately $9.3 million as of June 30, 2022, a $0.2 million decrease from the estimate as of December 31, 2021.
Total other income was $0.05 million in the three months ended June 30, 2022, compared to other income of $0.1 million during the three months ended June 30, 2021. The decrease was primarily due to a smaller decrease in the fair value of our outstanding warrants during the three months ended June 30, 2022 compared to the three months ended June 30, 2021.
Net loss for the three and six months ended June 30, 2022, was $6.7 million and $12.4 million, or a net loss of $0.06 and $0.12 per basic and diluted share, compared to $11.0 million and $19.9 million, or $0.14 and $0.25 per basic and diluted share, for the same periods in 2021, respectively.
About Soleno Therapeutics, Inc.

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.
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 on the therapeutic use of diazoxide 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 PWS patients. In the PWS Phase 3 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 other metabolic parameters. Soleno has been in ongoing discussions with the FDA regarding additional data needed to support the submission of an NDA.
