We look forward to continuing to work with the FDA,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “Our launch teams are diligently preparing for a potential launch of DCCR, including development of market access strategies, sales force sizing, and identifying medical education needs. With a strong balance sheet, we are well-positioned to commercialize DCCR and deliver a much-needed new therapy to 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 Ended June 30, 2024 Financial Results

As of June 30, 2024, Soleno had $294.6 million of cash, cash equivalents and marketable securities.

Research and development expense was $12.3 and $26.9 million for the three and six months ended June 30, 2024, compared to $5.1 and $10.5 million in the same periods of 2023. The increase was primarily due to increased personnel costs, expenditures in support of our NDA submission and investments in supply chain activities in preparation for commercial launch.

General and administrative expense was $10.9 and $19.4 million for the three and six months ended June 30, 2024, compared to $3.2 and $6.0 million in the same periods of 2023. The increase was primarily related to higher non-cash stock-based compensation expense (see table), higher costs due to an increase in personnel and higher professional services expenses and costs associated with preparation for commercial launch.

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 sales of DCCR in accordance with the terms of our merger agreement with Essentialis. The fair value of the liability for the contingent consideration payable by us achieving two commercial sales milestones of $100 million and $200 million in cumulative revenue in future years was estimated to be $13.6 million as of June 30, 2024, a $2.0 million increase from the estimate as of December 31, 2023. During the six months ended June 30, 2023, the estimate increased by $0.6 million from the $8.8 million estimate as of December 31, 2022.

Total other income, net, was $3.0 and $5.1 million for the three and six months ended June 30, 2024, and $0.2 and $0.3 million in the same periods of 2023. The increase was primarily due to an increase in interest income driven by higher cash and cash equivalents and marketable securities during the six months ended June 30, 2024, compared to the six months ended June 30, 2023.

Net loss was approximately $21.9 million and $43.3 million, or $0.57 and $1.16 per basic and diluted share, for the three and six months ended June 30, 2024, and $8.5 and $16.8 million, or $0.81 and $1.69 per basic and diluted share, in the same periods 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.
