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

REDWOOD CITY, Calif., May 5, 2021 – 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 months ended March 31, 2021.

“We are continuing our dialogue with the U.S. Food and Drug Administration (FDA) to evaluate the appropriate next steps in our DCCR program for the treatment of Prader-Willi Syndrome (PWS) and work towards obtaining regulatory approval as expeditiously as possible,” said Anish Bhatnagar, M.D., Chief Executive Officer of Soleno Therapeutics. “The Soleno team remains committed to the development of DCCR and building an appropriate data set to support its development. To this end, we were excited to recently present behavioral outcomes data from caregiver interviews that summarized individual patient experiences during treatment with DCCR. We were also pleased to speak to the PWS community directly during the recent PWS DCCR Town Hall meeting where we reiterated our continued focus on DCCR and outlined the proposed necessary steps for submitting a marketing application to the FDA in the U.S. More importantly, we were able to listen to the stories about the individual study participants’ experiences during our completed Phase III clinical trial of DCCR, DESTINY PWS, and the ongoing long-term safety extension study.”

Dr. Bhatnagar continued, “We are grateful for the work completed by the Foundation for Prader-Willi Research and Prader-Willi Syndrome Association | USA in collecting the experiences of PWS patients and caregivers treated with DCCR. This petition, which was submitted to the FDA, was signed by more than 26,000 individuals in support of DCCR.”

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.

First Quarter Ended March 31, 2021 Financial Results

Research and development expenses were $7.2 million for the quarter ended March 31, 2021, compared to $6.7 million in the same period of 2020. The increase was primarily due to increased activities related to the DCCR development program. General and administrative expense was $3.0 million for the quarter ended March 31, 2021, compared to $2.0 million in the same period of 2020.

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 the sale of DCCR in accordance with the terms of the Essentialis merger agreement. The fair value was estimated to be approximately $9.3 million at March 31, 2021, resulting in a decrease in expense of approximately $1.0 million from the estimate at December 31, 2020.

Total other income was $0.2 million for the quarter ended March 31, 2021, compared to $3.4 million in the same period of 2020, and consisted primarily of the change in the fair value of our outstanding warrants.



Net loss for the quarter ended March 31, 2021, was approximately $9.0 million, or a net loss of $0.11 per basic and diluted share, compared to a net loss of approximately $5.9 million, or $0.13 per basic and diluted share, for the quarter ended March 31, 2020.

As of March 31, 2021, Soleno had cash and cash equivalents of approximately $41.6 million, compared to $49.2 million at 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 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.
