REDWOOD CITY, Calif., Aug. 08, 2023 (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 second quarter ended June 30, 2023.
Second Quarter 2023 and Recent Corporate Highlights
- Completed enrollment in the randomized withdrawal period of Study C602, a long-term treatment study of DCCR (Diazoxide Choline) Extended-Release tablets for the treatment of Prader-Willi syndrome (PWS).
- Top-line data expected around the end of third quarter 2023.
- Received $10 million in connection with closing of December 2022 Securities Purchase Agreement (SPA) for up to $60 million with Nantahala Capital Management, Abingworth and Vivo Capital, triggered by announcement of enrollment completion.
“We are eagerly awaiting top-line results from the fully-enrolled randomized withdrawal period of Study C602, which remain on track for the third quarter of 2023,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “If successful, results have the potential to support a planned New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA). We continue to believe in the significant potential of DCCR as an effective and safe therapy for patients with 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.
Second Quarter 2023 Financial Results
As of June 30, 2023, Soleno had cash and cash equivalents of approximately $19.4 million, which includes $10 million received during the quarter from the sale of warrants pursuant to the terms of the SPA. The warrants issued during the quarter are immediately exercisable for up to an additional $50 million of gross proceeds to the Soleno; $15 million are required to be exercised within 30 days of the announcement of positive top-line data and $35 million of the warrants will expire if not exercised within 30 days of receipt of FDA approval of DCCR for the treatment of PWS.
Research and development expenses for the three and six months ended June 30, 2023, were $5.1 million and $10.5 million, compared to $3.7 million and $7.7 million for the same periods of 2022. Soleno’s research and development expenditures will 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, 2023, were $3.2 million and $6.0 million, compared to $2.5 million and $5.1 million for the same periods of 2022. The increase was mainly attributable to an increase in stock-based compensation and professional services 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 future commercial milestones associated with the sales of DCCR in accordance with the terms of Soleno’s merger agreement with Essentialis. The fair value of the liability for the contingent consideration payable by us was estimated to be $9.4 million as of June 30, 2023, a $0.3 million increase from the estimate as of March 31, 2023.
Total other income was $0.15 million and $0.26 in the three and six months ended June 30, 2023, compared to other income of $0.05 million and $0.10 million for the same periods of 2022. The increase was primarily due to an increase in interest income during the three and six months ended June 30, 2023 compared to the same periods of 2022.
Net loss for the three and six months ended June 30, 2023, was $8.5 million and $16.8 million, or a net loss of $0.81 and $1.69 per basic and diluted share, compared to $6.7 million and $12.4 million, or $0.72 and $1.69 per basic and diluted share, for the same periods in 2022.
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% 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. Diazoxide choline has received Orphan Drug Designation for the treatment of PWS in the U.S. and E.U., 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.
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 extended-release tablets, a once-daily oral tablet for the treatment of Prader-Willi syndrome (PWS), is currently being evaluated in a Phase 3 clinical development program.
