REDWOOD CITY, Calif., March 31, 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 announced financial results for the fourth quarter and full-year ended December 31, 2021.

Fourth Quarter 2021 and Recent Corporate Highlights

• Received official meeting minutes on January 20, 2022, from the December 21, 2021, Type C meeting with the U.S. Food and Drug Administration’s (FDA) Division of Psychiatry. The purpose of the meeting was to discuss the adequacy of the data submitted to the FDA by Soleno in October 2021 to support a potential New Drug Application (NDA) submission for diazoxide choline extended-release (DCCR) tablets for the treatment of Prader-Willi syndrome (PWS), as well as possible ways to generate additional controlled clinical data. Soleno recently submitted a study proposal involving participants currently enrolled in Study C602, Soleno’s ongoing open-label extension study, and intends to initiate the study after alignment with the FDA is reached.
• Announced that Running for Research - Prader-Willi Syndrome, an organization committed to raising private donations in support of advancing the science around PWS, will fund an investigator-sponsored clinical study to evaluate DCCR in patients with early phase PWS
• Closed $15 million public offering on March 31, 2022
• Participated in the BIO CEO & Investor Conference
  • Participated in the LifeSci Partners 11^th Annual Corporate Access Event

“Following our recent discussions with the FDA, the Soleno team remains focused on advancing our late-stage DCCR program to an NDA submission,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “Based on the feedback from the FDA, we recently submitted a study proposal to generate additional controlled clinical data involving patients currently enrolled in our ongoing open-label extension study, Study C602. Once alignment with the FDA is reached, we anticipate study initiation shortly thereafter. We remain confident in DCCR’s efficacy and safety based on the considerable data we have generated to date and look forward to continuing to work closely with the FDA, providers, patients and the entire PWS community to bring this important therapy to people with PWS. Importantly, we strengthened our balance sheet through the recent successfully completed public offering and are well-positioned to continue executing on our product development and corporate growth initiatives.”

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.

Fourth Quarter and Full Year Ended December 31, 2021 Financial Results from Operations

Research and development expenses were $3.8 million for the quarter ended December 31, 2021, compared to $5.6 million in the same period of 2020, and $21.5 million for the year ended December 31, 2021, compared to $23.2 million for the year ended 2020. The decrease was primarily due to the completion of the DESTINY PWS study in June 2020 and the subsequent winding down of associated activities and costs.

General and administrative expense was $2.6 million for the quarter ended December 31, 2021, compared to $2.3 million in the same period of 2020, and $10.8 million for the year ended December 31, 2021, compared to $8.8 million for the year ended 2020. The increase was primarily related to increased compensation costs, professional services and corporate business development expenses.

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 sale of DCCR in accordance with the terms of the Essentialis merger agreement. In December 2021, in connection with the dissolution of two of the former Essentialis stockholders, the two former stockholders entered into an agreement with Soleno which assigned the right, title and interest to all their future earnout payments to Soleno. As a result of the assignment, as of December 31, 2021, and going forward, the maximum cash earnout payments have been reduced from $30.0 million to $21.2 million. The fair value of the contingent liability as of December 31, 2021, was $9.5 million compared to $10.3 million as of December 31, 2020.

Total other income was $0.2 million and $5.2 million for the fourth quarter ended December 31, 2021, and 2020, respectively, and $0.6 million and $11.7 million for the year ended December 31, 2021, and 2020, respectively. Total other income consisted primarily of the change in the fair value of the liability for Soleno’s outstanding warrants and was primarily due to the 2017 PIPE warrants expiring unexercised at the end of 2020.

Net loss was approximately $2.8 million, or $0.04 per basic and diluted share, for both fourth quarters ended December 31, 2021 and 2020.

Net loss for the year ended December 31, 2021, was approximately $30.9 million, or $0.39 per basic and diluted share, compared to a net loss of approximately $24.6 million, or $0.39 per basic and diluted share, for the year ended December 31, 2020.

As of December 31, 2021, Soleno had cash and cash equivalents of approximately $21.3 million, as compared to $49.2 million as of December 31, 2020. On March 31, 2022, the Company completed a public offering of its common stock and, for certain investors, in lieu of common stock, prefunded warrants, and for each share of common stock or pre-funded warrant, one immediately exercisable common warrant. The net proceeds of the offering are expected to be $13.9 million after deducting the underwriting discount and other estimated offering expenses, and assuming that no pre-funded warrants are immediately exercised.

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 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. Soleno has been in ongoing discussions with the FDA regarding additional data needed to support the submission of an NDA.
