Some of the key facts of the Prader-Willi Syndrome Market Report: https://www.delveinsight.com/sample-request/prader-willi-syndrome-market?utm_source=openpr&utm_medium=pressrelease&utm_campaign=gpr
• The Prader-Willi Syndrome market size was valued ~USD 600 million in 2023 and is anticipated to grow with a significant CAGR during the study period (2020-2034)
• In April 2025, Vykat XR featured an extended-release formulation of diazoxide choline, the crystalline salt form of diazoxide. While its precise mechanism of action remains uncertain, it is believed to reduce hyperphagia in individuals with Prader-Willi syndrome by activating ATP-sensitive potassium channels in the hypothalamus. The FDA approval was based on results from a 16-week, Phase 3, double-blind, placebo-controlled, randomized withdrawal trial (ClinicalTrials.gov Identifier: NCT03714373), which was preceded by an open-label treatment phase with diazoxide choline extended-release.
• In March 2025, The FDA approved Soleno Therapeutics' diazoxide choline (DCCR) extended-release tablets, branded as Vykat XR, for managing hyperphagia in individuals aged 4 and older with Prader-Willi syndrome (PWS). This marks a significant milestone as Vykat XR becomes the first approved therapy specifically targeting hyperphagia in PWS. DCCR is a proprietary, once-daily extended-release formulation of diazoxide choline, the crystalline salt form of diazoxide, designed to address the excessive hunger characteristic of the condition.
• In March 2025, Soleno Therapeutics, Inc. (NASDAQ: SLNO), a biopharmaceutical company focused on developing innovative treatments for rare diseases, has announced that the U.S. Food and Drug Administration (FDA) has approved VYKAT XR (diazoxide choline) extended-release tablets, formerly known as DCCR, for treating hyperphagia in adults and children aged 4 and older with Prader-Willi syndrome (PWS).
• In March 2025, The FDA has granted approval to Soleno Therapeutics' diazoxide choline (DCCR) extended-release tablets, branded as Vykat XR, for the treatment of Prader-Willi syndrome (PWS) in patients aged 4 years and older with hyperphagia. DCCR, a unique extended-release formulation containing diazoxide choline (the crystalline salt of diazoxide), is administered once daily and becomes the first treatment specifically targeting hyperphagia in PWS.
• The overall market size for PWS in the US was projected to be approximately USD 500 million in 2023, with expectations for growth throughout the forecast period (2024-2034).
• In EU4 and the UK, Germany held the largest market share, with a market size of approximately USD 30 million in 2023, and this is anticipated to increase during the forecast period (2024-2034).
• There is significant uncertainty regarding the therapies from Gedeon Richter and Palobiofarma due to a lack of substantial evidence on their safety and efficacy. In contrast, Palobiofarma's PBF-999 is anticipated to be launched first in Spain.
• In 2023, the US had the highest number of prevalent cases of PWS among the 7MM, totaling approximately 22,600 cases, which are projected to rise during the forecast period.
• In 2023, Germany had the highest number of total prevalent cases of PWS among the EU4 and the UK, whereas Spain recorded the lowest number of cases.
• Estimates indicate that in Japan, PWS was most commonly seen in the 18-40 age group, representing over 38% of all cases in 2023.
• In 2023, within the United States, the paternal microdeletion subtype represented the largest share of genetic subtype-specific cases of PWS, comprising around 70% of cases, while the translocation subtype was the least prevalent.
• Key Prader-Willi Syndrome Companies: Novo Nordisk, Pfizer, Sandoz, Harmony Biosciences, Soleno Therapeutics, Harmony Biosciences, ACADIA Pharmaceuticals, Aardvark Therapeutics, Gedeon Richter, Palobiofarma, ConSynance Therapeutics, and others
• Key Prader-Willi Syndrome Therapies: NORDITROPIN, GENOTROPIN, OMNITROPE, WAKIX (pitolisant), Diazoxide Choline Controlled-Release (DCCR), WAKIX (pitolisant), DCCR (diazoxide choline), Carbetocin (LV-101), ARD-101, RGH-706, PBF-999, CSTI-500, and others
• The Prader-Willi Syndrome market is expected to surge due to the disease's increasing prevalence and awareness during the forecast period. Furthermore, launching various multiple-stage Prader-Willi Syndrome pipeline products will significantly revolutionize the Prader-Willi Syndrome market dynamics.

Prader-Willi Syndrome Overview
Prader-Willi Syndrome (PWS) is a complex genetic disorder that affects many parts of the body. The condition is characterized by weak muscle tone (hypotonia) and feeding difficulties in infancy, followed by excessive eating and gradual development of obesity. Individuals with Prader-Willi Syndrome typically have intellectual disability, behavioral problems, and distinctive physical features such as almond-shaped eyes, a narrowing of the head at the temples, and a turned-down mouth.
