Third Quarter 2023 and Recent Corporate Highlights Announced positive statistically significant top-line data from 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). The study met its primary endpoint, demonstrating a highly statistically significant difference in change from baseline in HQ-CT total score for DCCR compared to placebo (p=0.0022)Secondary endpoints of Clinical Global Impression of Severity (CGI-S) and Clinical Global Impression of Improvement (CGI-I) both showed strong trends towards worsening in the placebo group compared to DCCR (p=0.08 and 0.09), respectively.DCCR continued to be generally well-tolerated in the randomized withdrawal period with no new or unexpected safety signals, including no serious adverse events or discontinuations due to adverse events occurring in any participants in the treatment group. Presented results from the randomized withdrawal phase of Study C602 at the Foundation for Prader-Willi Research (FPWR) 2023 Research Symposium held on October 5-6, 2023 in Denver, Colorado.Closed on gross proceeds of approximately $129 million from an underwritten public offering of common stock and concurrent private placement of common stock and pre-funded warrants in October 2023.Appointed industry veteran Matthew Pauls, J.D., M.B.A. to the Board of Directors. Mr. Pauls currently serves as Chair of the Board of Directors and Chief Executive Officer of Savara, Inc., a biopharmaceutical company focused on rare respiratory diseases. He is also a member of the Board of Directors at Amplo Biotechnology, a private gene therapy company focused on rare neuromuscular disorders. Previously, he was President and Chief Executive Officer and a member of the Board of Directors at Strongbridge Biopharma plc. In addition, Mr. Pauls has significant experience in global commercial roles, including at Insmed, Shire Pharmaceuticals, Bristol-Myers Squibb and Johnson & Johnson.Hired Mike Huang, M.D. as Senior Vice President of Clinical Development.

Dr. Huang’s therapeutic experience spans an array of indications, including rare/orphan diseases, endocrinology, neurology and oncology.
“The recent announcement of positive results from the randomized withdrawal phase of Study C602 was a significant milestone for us,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “We are continuing our ongoing work preparing a New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA), currently planned for mid-2024. Importantly, following our successfully completed public offering and concurrent private placement, we have initiated commercial readiness activities and are well-capitalized to execute on our planned corporate strategy leading up to and beyond potential approval of DCCR for 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. Third Quarter 2023 Financial Results
As of September 30, 2023, Soleno had cash and cash equivalents of approximately $52.4 million, which includes $8.4 million received from exercised warrants issued as part of the Company’s March 2022 public offering, and $15 million received from the exercise of previously issued Tranche A warrants in connection with Soleno’s December 2022 Securities Purchase Agreement which were triggered by the announcement of positive top-line data. In addition, $16.0 million of the $129 million public and concurrent private financing was received in September 2023.The remaining proceeds were received upon the closing of the transaction in October 2023, together with an additional $17.5 million from exercised Tranche B warrants in connection with the December 2022 Securities Purchase Agreement. In aggregate, the Company received $169.9 million in gross proceeds from these financing activities. Research and development expenses for the three and nine months ended September 30, 2023, were $6.0 million and $16.5 million, compared to $3.8 million and $11.5 million for the same periods of 2022. Soleno’s research and development expenditures 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 nine months ended September 30, 2023, were $3.3 million and $9.3 million, compared to $2.3 million and $7.4 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 commercial milestones associated with the future 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 achieving two commercial sales milestones of $100 million and $200 million in revenue in future years was estimated to be $10.5 million as of September 30, 2023, a $1.1 million increase from the estimate as of June 30, 2023. Total other expense was $0.5 million and $0.2 million in the three and nine months ended September 30, 2023, compared to other income of $0.1 million and $0.2 million for the same periods of 2022. The decrease was primarily due to the change in fair value of warrants liabilities, partially offset by an increase in interest income during the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. Net loss for the three and nine months ended September 30, 2023, was $10.9 million and $27.7 million, or a net loss of $0.95 and $2.65 per basic and diluted share, compared to $6.1 million and $18.6 million, or $0.65 and $2.31 per basic and diluted share, for the same periods in 2022.

About PWSThe 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 TabletsDCCR 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, 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 Designation in the U.S. 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 PWS, recently completed its Phase 3 development program to support a planned NDA submission.
