Third Quarter 2024 and Recent Corporate Highlights

• Announced updates to its Board of Directors:
  • Appointed Dawn Carter Bir, a seasoned biotechnology executive with over 30 years of industry executive leadership and strategic experience, to Soleno’s Board of Directors.
  • Current Board member Matthew Pauls, J.D., M.B.A assumed the role of Lead Independent Director.

“In the third quarter of 2024, we achieved a major milestone with FDA acceptance of our NDA seeking approval of DCCR for the treatment of PWS,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “Our dialogue with the FDA has been productive to date, and we look forward to continued collaboration as the review process advances. As we look towards potential approval of DCCR, our commercial team continues to prepare for our planned U.S. market launch. Our strong balance sheet supports successful execution of a launch and the delivery of a transformative therapy to people living with PWS, if approved.”

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.

Third Quarter Ended September 30, 2024 Financial Results

Soleno used $14.9 million of cash in its operating activities during the three months ended September 30, 2024, and had $284.7 million of cash, cash equivalents and marketable securities.

Research and development expense was $30.1 million, which includes $18.5 million of non-cash stock-based compensation, for the three months ended September 30, 2024, compared to $6.0 million, which includes $0.9 million of non-cash stock-based compensation in the same period of 2023. Personnel and associated costs increased $2.4 million as we hired additional employees in support of our research and development activities. Consulting costs in support of our NDA submission and preparation for a submission to the European Medicines Agency increased $2.7 million, and we invested $1.3 million in supply chain activities in preparation for commercial launch. The cadence of our research and development expenditures will fluctuate depending upon the state of our clinical programs, the timing of manufacturing and other projects necessary to support the submission of our NDA and prepare for commercial launch. The $17.6 million of additional non-cash stock-based compensation being recognized in the period is predominantly due to performance-based RSU grants which partially vested upon the acceptance by the FDA of the NDA submission and fully vest upon the approval by the FDA (see table below).

General and administrative expense was $49.2 million, which includes $38.1 million of non-cash stock-based compensation, for the three months ended September 30, 2024, compared to $3.3 million, which includes $1.3 million of non-cash stock-based compensation, in the same period of 2023. Personnel and associated costs increased $3.0 million as we hired additional employees in preparation for commercial launch and in support of our increased business activities. Professional services expenses and other program costs associated with preparation for commercial launch, including medical affairs activities, increased by $5.9 million. The $36.8 million of additional non-cash stock-based compensation being recognized in the period is predominantly due to performance-based RSU grants which partially vested upon acceptance by the FDA of the NDA submission and fully vest upon approval by the FDA (see table below).

We are 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 $14.5 million as of September 30, 2024, a $0.9 million increase from the estimate as of June 30, 2024.

Total other income, net, was $3.6 million for the three months ended September 30, 2024, compared to total other expense, net, of $0.5 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, marketable securities and long-term marketable securities during the three months ended September 30, 2024, compared to the three months ended September 30, 2023.

Net loss was approximately $76.6 million, or $1.83 per basic and diluted share, for the three months ended September 30, 2024, and $10.9 million, or $0.95 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.
