Soleno Therapeutics Provides Corporate Update and Reports Second Quarter 2021 Financial Results

REDWOOD CITY, Calif., July 28, 2021 (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 three and six months ended June 30, 2021.

“The Soleno team remains focused on achieving regulatory approval for DCCR for the treatment of Prader-Willi syndrome, or PWS,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “We are continuing our dialogue with the U.S. Food and Drug Administration (FDA) and, as recently announced, intend to submit the clinical study reports from DESTINY PWS and the C602 extension study, as well as additional data, to the Agency before the end of the third quarter. The FDA has agreed to review these clinical study reports and data to determine if the totality of data generated to date for DCCR are sufficient to support a potential New Drug Application (NDA) submission.”

Second Quarter 2021 and Recent Corporate Highlights

• Continued discussions with FDA and currently evaluating appropriate next steps for DCCR program in PWS
  
  • On July 2, 2021, the Company received official meeting minutes from the June 11, 2021, Type B meeting with the Division of Diabetes, Lipid Disorders and Obesity. The FDA continued to assert that based on the data the Agency has seen to date, an additional clinical trial is necessary for the submission of an NDA. However, the FDA strongly encouraged Soleno to submit the available data and clinical study reports for the Company’s Phase 3 trial, DESTINY PWS (C601), and its long-term, open-label extension study (C602), to allow FDA to assess if these studies may provide adequate evidence of safety and efficacy to support the submission of an NDA.
  • As of June 2021, 97 patients in study C602 have completed one year in the study
• Expanded patent protection for DCCR for the treatment of PWS
  
  • Received notice of allowance of patents covering the use of diazoxide choline and diazoxide to treat behavioral, metabolic and body composition complications of PWS in New Zealand, Mexico and Canada. Soleno has already successfully prosecuted this patent filing to issuance of three U.S. patents (9,757,384, 10,058,557, and 10,456,408), and corresponding patents in the EU, Japan, China, Australia, Malaysia, Indonesia and Eurasia. These patents extend protection of DCCR in the treatment of PWS to at least 2035 in all of these regions.
• A manuscript titled, “A Qualitative Methodology for Evaluating Novel Treatments for Hyperphagia in People with Prader-Willi Syndrome” published online in the International Journal of Rare Diseases and Disorders
  
  • Highlighted collaboration with Casimir Inc. to capture individual patient experience data from participants in the DESTINY PWS study and its long-term extension study. The publication summarizes the methodology utilized to collect these patient experience data that might not otherwise be captured by existing caregiver reported outcome tools.  
  • Subset of interviews conducted from this study were analyzed utilizing natural language processing to better understand the complexities of PWS behaviors and outcomes. Results presented at the Pediatric Academic Societies (PAS) 2021 Virtual Annual Meeting.
• Hosted webinar highlighting DCCR for the treatment of Prader-Willi syndrome at the European Congress on Endocrinology 202
  
  • Webinar, titled “Results from DESTINY PWS, a Randomized Double-Blind Placebo-Controlled Phase 3 Study in Subjects with Prader-Willi Syndrome,” featured presentations by PWS key opinion leaders from France and the UK.
• Participated in the Oppenheimer Rare & Orphan Disease Summit
• Received Orphan Drug Designation from the FDA for DCCR for the treatment of Glycogen Storage Disease Type 1a (GSD 1a), or von Gierke disease

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.

Financial Results for Three and Six Months Ended June 30, 2021

Research and development expenses for the three and six months ended June 30, 2021, were $5.6 million and $12.8 million, compared to $6.1 million and $12.8 million for the same periods of 2020. The fluctuations in expenses were primarily due to the cadence of activities related to the DCCR development program.

General and administrative expenses for the three and six months ended June 30, 2021, were $2.5 million and $5.4 million, compared to $2.2 million and $4.3 million for the same periods of 2020. The increase was primarily related to increased personnel-related costs.

The change in the fair value of contingent consideration results from Soleno’s obligation to make cash payments to Essentialis stockholders upon the achievement of certain future commercial milestones associated with commercial sales of DCCR in accordance with the terms of the Essentialis merger agreement. The fair value was estimated to be approximately $12.3 million as of June 30, 2021, a $3.0 million increase from the estimate on March 31, 2021, and a $2.0 million increase from the estimate on December 31, 2020.

Total other income was $0.1 million in the three months ended June 30, 2021, compared to other income of $3.8 million during the three months ended June 30, 2020, and consisted primarily of the change in the fair value of the Company’s outstanding warrants.

Net loss for the three and six months ended June 30, 2021, was $11.0 million and $19.9 million, or a net loss of $0.14 and $0.25 per basic and diluted share, compared to $7.4 million and $13.2 million, or $0.16 and $0.29 per basic and diluted share, for the same periods in 2020, respectively.

As of June 30, 2021, Soleno had cash and cash equivalents of approximately $33.6 million, as compared to $49.2 million on December 31, 2020.

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 EU, and Fast Track Designation in the U.S.
