Soleno Therapeutics (SLNO) - Major Customers

Soleno Therapeutics (SLNO) is a clinical-stage biopharmaceutical company. As of the current date, the company's primary focus is on the development of its lead product candidate, DCCR (Diazoxide Choline Extended-Release tablets), for the treatment of Prader-Willi Syndrome (PWS).

Soleno Therapeutics does not currently have any commercialized products approved for sale on the market. Consequently, the company does not have major customers in the traditional sense of companies or individuals purchasing its products. Their activities are centered on clinical development and seeking regulatory approval for DCCR.

Therefore, it is not applicable to list major customer companies or categories of individual customers served, as Soleno Therapeutics is not yet generating revenue from product sales.

The clear emerging threat to Soleno Therapeutics (SLNO) is the increasing investigation and potential use of glucagon-like peptide-1 (GLP-1) receptor agonists, and related multi-agonists like GLP-1/GIP, for the treatment of Prader-Willi Syndrome (PWS). While not yet approved specifically for PWS, these drugs are already widely successful in managing obesity and type 2 diabetes due to their significant effects on appetite suppression and weight loss. Several clinical trials and research initiatives are exploring their efficacy and safety in the PWS population. Given their established safety profiles and strong efficacy in related metabolic conditions, there is a clear potential for GLP-1 agonists to emerge as a competitive or even superior treatment option for hyperphagia and other symptoms in PWS, potentially challenging Soleno's DCCR (Diazoxide Choline Controlled Release) once it reaches the market.

• Global Market: The global Prader-Willi Syndrome market size was estimated at USD 599.81 million in 2023 and is projected to grow to USD 1131.94 million by 2033, with a Compound Annual Growth Rate (CAGR) of 6.56%. Another estimate places the global market at US$ 633.56 million in 2024, expected to reach US$ 1,078.80 million by 2033, growing at a CAGR of 6.0%. VYKAT™ XR (formerly DCCR) accounted for the largest market share in 2023 within the hyperphagia treatment segment of the global Prader-Willi Syndrome market.
• U.S. Market: Approximately 20,000 individuals in the United States are estimated to have Prader-Willi Syndrome. Annual revenue for VYKAT™ XR in the U.S. is expected to reach $404 million by 2034.
• European Market (France, Germany, Italy, Spain, and U.K.): It is estimated that 9,500 people live with PWS across these five European countries. Soleno Therapeutics is pursuing European regulatory approval for VYKAT™ XR.
• 7MM Market (United States, EU4, and Japan): The market size for Prader-Willi Syndrome in these seven major markets reached USD 600 million in 2023 and is expected to increase by 2034.

Soleno Therapeutics (SLNO) is poised for significant future revenue growth over the next 2-3 years, primarily driven by the following factors:

1. Continued Commercialization and Market Adoption of VYKAT™ XR in the U.S.: The successful U.S. launch and robust market adoption of VYKAT™ XR (diazoxide choline extended-release tablets) for the treatment of hyperphagia in Prader-Willi Syndrome (PWS) patients is a key driver. Soleno Therapeutics reported a Q3 2025 revenue surge to $66 million, significantly exceeding estimates, largely due to VYKAT™ XR's success. The company has seen strong adoption, with 764 individuals actively treated and 397 patient start forms recorded in Q3 2025, and aims to continue its revenue growth through patient education and engagement. Analysts project significant growth for the drug, with some forecasting peak revenues of $2 billion.
2. Regulatory Approval and Market Expansion of DCCR in Europe: Soleno Therapeutics is actively pursuing regulatory approval for DCCR in Europe, currently addressing day 120 questions from the European Medicines Agency (EMA). Successful approval in the EU would substantially expand their addressable market, as there are an estimated 9,500 people with PWS in major European countries (France, Germany, Italy, Spain, and the U.K.). This international expansion is a priority and a key component of the company's forward-looking growth strategy.
3. Potential Expansion of DCCR to Other Genetic Obesities: Beyond its primary indication in PWS, Soleno is evaluating DCCR's potential as a treatment for pediatric patients with other genetic obesities, including SH2B1 deficiency, obesity associated with PCSK1 mutation (rs6232 variant), and SIM1 deficiency. If successful, this pipeline expansion could unlock new, larger markets for DCCR, offering additional avenues for revenue generation in the future.
4. Increasing Awareness and Diagnosis Rates of Prader-Willi Syndrome: The overall Prader-Willi Syndrome market is projected to grow, fueled by rising awareness and improved diagnosis rates. The PWS market is estimated to reach $1.59 billion by 2032, growing at a compound annual growth rate (CAGR) of 7.2% from 2025. As the first FDA-approved treatment for hyperphagia in PWS, VYKAT™ XR is well-positioned to capitalize on this expanding market and benefit from the increasing patient population seeking effective treatments.
