Key Highlights

  • In 2023, in the 7MM the total market size of PWS was more than USD 600 million.
  • PWS is a multifaceted genetic disorder characterized by a range of challenging symptoms, including hyperphagia (excessive hunger), obesity, and behavioral issues. PWS is often misdiagnosed in neonates because of its nonspecific clinical manifestations.
  • Definitive molecular genetic testing should be readily accessible for diagnosing PWS in the laboratory. Early diagnosis of PWS enables treatments that can greatly alleviate some of its symptoms.
  • PWS presents a significant opportunity for breakthrough treatments. An effective, approved therapy could not only extend survival but also increase the prevalence of the population over time.
  • Currently, PWS patients are primarily managed through weight control with dietary interventions and strict supervision. Pharmacological treatment mainly involves growth hormone supplementation, which is the leading therapy due to the common growth hormone deficiency in PWS patients.
  • Growth hormone replacement therapy is the only FDA-approved treatment for children with PWS, but it is approved solely to address growth failure and does not impact hyperphagia or behavioral issues.

The FDA has approved three growth hormone products for PWS: GENOTROPIN, NORDITROPIN, and OMNITROPE. In contrast, both the EMA and

MHLW have only approved GENOTROPIN for PWS. Additionally, OMNITROPE is approved as a biosimilar for PWS in Europe.
  • New companies are consistently entering the PWS market. Key players currently include Harmony Biosciences, Soleno Therapeutics, ACADIA Pharmaceuticals, Aardvark Therapeutics, Gedeon Richter, Palobiofarma, Tonix Pharmaceuticals, ConSynance Therapeutics, among others, who are working on developing therapies for PWS.
  • DCCR, developed by Soleno Therapeutics, is designed for once-daily dosing and targets hyperphagia in PWS. As no drug is currently approved to treat hyperphagia in children and adolescents with PWS, DCCR may capture a significant market share if it receives approval.
  • PWS management is evolving with ongoing research and emerging treatments. Addressing current treatment gaps and advancing research is critical for improving the quality of life for individuals with PWS.
The " Prader-Willi Syndrome (PWS) - Market Insights, Epidemiology, and Market Forecast - 2034" report delivers an in-depth understanding of PWS, historical and forecasted epidemiology as well as the PWS market trends in the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan.

Prader-Willi Syndrome (PWS) Disease Understanding and Treatment Algorithm

PWS Overview

PWS is a rare genetic disorder affecting both sexes from birth throughout their lives. It results in low muscle tone, motor developmental delays, and mild to moderate learning difficulties, incomplete sexual development, and emotional and social immaturity, often leading to challenging behaviors. A chronic, insatiable appetite typically develops in childhood, leading to food seeking, stealing, and potentially life-threatening obesity without strict food management and exercise.

First described in a 1956 article by Andrea Prader, Heinrich Willi, and Alexis Labhart, PWS was initially noted for obesity, short stature, cryptorchidism, intellectual disability, and early failure to thrive in infants. Now, PWS is recognized as a severe neurodevelopmental disorder characterized by cognitive disabilities, behavioral issues, hyperphagia, and endocrine dysfunctions.

PWS Diagnosis

The journey to diagnosing PWS typically begins with parents noticing early signs such as poor muscle tone and feeding difficulties in infancy. Concerned parents consult a pediatrician, who, upon observing developmental delays and distinctive facial features, refers them to a genetic specialist. The specialist conducts a detailed clinical examination and orders genetic tests, primarily DNA methylation analysis, to confirm PWS. Additional tests like FISH and MS-MLPA may be conducted if necessary. Once diagnosed, the specialist explains the condition, and a multidisciplinary care plan is developed, involving endocrinologists, dietitians, and therapists. Regular follow-ups and interventions are essential to manage symptoms and support the child’s development.

PWS Treatment

The treatment of PWS focuses on addressing the specific symptoms in each individual. Early intervention and strict adherence to treatment significantly enhance health and quality of life for affected individuals and their families. A coordinated effort by a team of specialists, including geneticists, pediatricians, orthopedists, endocrinologists, speech therapists, psychologists, dietitians, and nutritionists, is essential to develop an effective treatment program. Genetic counseling is recommended to discuss the condition and recurrence risks. Parents are advised to learn proper techniques for managing behavioral and eating issues, which improves prognosis. Growth hormone therapy, approved by the FDA in 2000, is beneficial for increasing height, improving body composition, mobility, and respiratory function, and may enhance development and behavior. Early intervention is crucial for addressing motor skills, intellectual disability, and speech and language development.

Prader-Willi Syndrome (PWS) Epidemiology

The PWS epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by the total prevalent cases of PWS, total diagnosed prevalent cases of PWS, age-specific cases of PWS, and PWS cases by Genetic Subtype in the 7MM market covering the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034.
  • Among the 7MM, the US accounted for the highest prevalent cases of PWS in 2023, with around 22,600 cases; these cases are expected to increase during the forecast period.
  • Amongst EU4 and the UK, the total prevalent cases of PWS were highest in Germany, while the lowest number of cases were in Spain in 2023.
  • According to the estimates, in Japan, it is observed that PWS was most prevalent in the 18-40 years age group, accounting for over 38% of total cases in 2023.
  • In 2023, among genetic subtype-specific cases of PWS in the US, the paternal microdeletion subtype accounted for the highest proportion, approximately 70% of cases, while the translocation subtype was the least common.

Prader-Willi Syndrome (PWS) Drug Chapters

The drug chapter segment of the PWS report encloses a detailed analysis of the late-stage (Phase III), mid-stage (II), and early-stage (Phase I) pipeline drugs. Hormonal therapies such as GENOTROPIN, OMNITROPE, and NORDITROPIN are currently being used for treating PWS. The current key players for emerging drugs and their respective drug candidates include Harmony Biosciences (pitolisant) and Soleno Therapeutics (diazoxide choline controlled release). The drug chapter also helps understand the PWS clinical trial details, expressive pharmacological action, agreements and collaborations, approval, and patent details, and the latest news and press releases.

Marketed Drug

NORDITROPIN: Novo Nordisk

NORDITROPIN (somatropin) is a recombinant human growth hormone and is developed by Novo Nordisk. NORDITROPIN is a polypeptide hormone of recombinant DNA origin. The hormone is synthesized by a special strain of E. coli bacteria that has been modified by the addition of a plasmid that carries the gene for human growth hormone. NORDITROPIN contains the identical sequence of 191 amino acids constituting the naturally occurring pituitary human growth hormone with a molecular weight of about 22,000 Daltons. In February 2018, the US FDA approved NORDITROPIN for the treatment of growth failure due to PWS.

Emerging Drugs

WAKIX (pitolisant): Harmony Biosciences

Pitolisant is a selective histamine 3 (H3) receptor antagonist/inverse agonist. The mechanism of action of WAKIX is unclear; however, its efficacy could be mediated through its activity at H3 receptors, thereby increasing the synthesis and release of histamine, a wake-promoting neurotransmitter. WAKIX was designed and developed by Bioprojet (France). Harmony has an exclusive license from Bioprojet to develop, manufacture, and commercialize pitolisant in the United States. WAKIX is FDA-approved to treat EDS or cataplexy in adult patients with narcolepsy. Pitolisant is not approved for use in patients with PWS and is currently being evaluated in PWS. The US FDA granted Orphan Drug designation to pitolisant for the treatment of PWS in February 2024. Harmony Biosciences is also developing HBS-102 for PWS.

In April 2024, Harmony Biosciences initiated its global Phase III registrational trial, the TEMPO study, to evaluate the safety and efficacy of pitolisant as a treatment for excessive daytime sleepiness (EDS) and behavioral symptoms in patients aged 6 years and older with PWS.

Diazoxide Choline Controlled-Release (DCCR): Soleno Therapeutics

DCCR is a novel, proprietary extended-release dosage form containing diazoxide choline, the crystalline salt of diazoxide, and is administered once daily. The parent molecule, diazoxide, has been used for decades in thousands of individuals in a few rare diseases in neonates, infants, children, and adults but is not approved for use in PWS. Soleno conceived of and established extensive patent protection for the therapeutic use of diazoxide, diazoxide choline, and DCCR in individuals with PWS. The US FDA has granted breakthrough therapy designation to diazoxide choline for the treatment of adults and children ages 4 years and older with genetically confirmed PWS who have hyperphagia in April 2024.

In June 2024, Soleno Therapeutics submitted the NDA to the US FDA for approval of DCCR tablets for the treatment of PWS in individuals 4 years and older who have hyperphagia.

Drug Class Insight

H3-receptor antagonist/inverse agonist

Since the discovery of H3R, numerous studies have examined the clinical impact of its modulation through various drugs. Harmony Biosciences’ pitolisant, a first-in-class H3-receptor antagonist/inverse agonist, is already approved for narcolepsy and is now being evaluated for PWS. The Phase III TEMPO study, which began in April 2024, is investigating pitolisant’s efficacy and safety for treating EDS and behavioral issues in patients aged 6 and older with PWS. In February 2024, the FDA granted ODD to pitolisant for PWS. Phase II data revealed that pitolisant led to a clinically significant reduction of 3.7-5.5 points in EDS across all age groups, with the most notable effects in children aged 6-11. The drug also showed some improvement in hyperphagia, although baseline scores were generally normal to mild.

Other classes being explored in the PWS market include KATP channel activators, PDE-10 inhibitors, MCHR1 protein inhibitors, and others. It is too early to predict which drug will dominate the PWS market and demonstrate significant efficacy and safety, as many of these are new, and no results have been published yet.

Prader-Willi Syndrome (PWS) Market Outlook

Current treatment options for PWS are limited, with management primarily focusing on lifestyle modifications to prevent obesity-related deaths. Nearly half of the deaths in PWS patients under 18 are linked to food-seeking behaviors such as choking and accidents. The clinical management of PWS spans many therapeutic domains, including nutritional, developmental, educational, hormonal, and behavioral support, with each stage of development requiring unique management strategies. Growth hormone treatment has been shown to increase growth velocity and height, improve body composition, and, with proper dietary management, prevent obesity. It also enhances physical and respiratory performance, thereby improving quality of life and potentially preventing long-term cardiovascular and metabolic issues such as hypercholesterolemia and diabetes. There is no cure for PWS, but professional healthcare from a range of specialists can improve the child’s quality of life, and it cannot be prevented. Treatment aims to ease some of the associated problems. First-line treatments for hyperphagia and obesity management in PWS involve intensive behavioral and nutritional interventions.

The FDA has approved three growth hormone products for PWS: Pfizer’s GENOTROPIN, Novo Nordisk’s NORDITROPIN, and Sandoz’s OMNITROPE. These approvals have allowed doctors to prescribe these products as equivalent treatments. The choice of growth hormone product often depends on the doctor’s experience, insurance requirements, cost, ease of use, and the patient’s history or sensitivities.

The market composition in Europe mirrors that of the US, with growth hormone and its synthetic substitutes being the most widely used, especially among children and adolescents. EMA approved OMNITROPE as its first biosimilar growth hormone in 2006, with GENOTROPIN being another major approved growth hormone product. In March 2012, the EMA Committee for Medicinal Products for Human Use (CHMP) completed an arbitration procedure. It denied a request to add a new indication for NORDITROPIN for use in PWS children.

The pipeline for PWS treatment includes promising drugs: DCCR (diazoxide choline), carbetocin (LV-101), pitolisant, ARD-101, and RGH-706, among others.

Detailed market assessment will be provided in the final report.

  • The total market size in the US for PWS was estimated to be ~USD 500 million in 2023, which is expected to grow during the forecast period (2024-2034).
  • In EU4 and the UK, Germany accounted for the largest share with ~USD 30 million market size in 2023, which is expected to grow during the forecast period (2024-2034).
  • - In 2034, among the emerging therapies, the highest revenue was generated by DCCR, in Japan.
  • There is high uncertainty around both Gedeon Richter and Palobiofarma's therapies due to the unavailability of substantial evidence around safety & efficacy data. Meanwhile, Palobiofarma's PBF-999 first launch is expected in Spain.

Prader-Willi Syndrome (PWS) Drugs Uptake

This section focuses on the uptake rate of potential drugs expected to be launched in the market during 2024-2034. The landscape of PWS treatment has experienced a transformation with the uptake of novel drugs. These innovative therapies are redefining standards of care as growth hormones are only approved for pediatric patients. There is a high unmet need for adult patients in PWS. More than 90% of patients have hyperphagia symptoms in PWS, most of the companies targeting this segment. According to analysis, significant potential drugs expected to make a substantial impact in the upcoming forecast period include DCCR (diazoxide choline), carbetocin (LV 101), and ARD-101, among others. DCCR showed promising results in these patients with first mover advantage in 2025 in the US with the highest commercial opportunity owing to its established efficacy in pivotal trials.

Universities such as the Insubria University, Professor of University of Glasgow, University of Washington, etc., were contacted. Their opinion helps understand and validate current and emerging therapy treatment patterns or PWS market trends. This will support the clients in potential upcoming novel treatments by identifying the overall scenario of the market and the unmet needs.

Qualitative Analysis

We perform Qualitative and market Intelligence analysis using various approaches, such as SWOT analysis and Conjoint Analysis. In SWOT analysis, strengths, weaknesses, opportunities, and threats in terms of gaps in disease diagnosis, patient awareness, physician acceptability, competitive landscape, cost-effectiveness, and geographical accessibility of therapies are provided.

Conjoint Analysis analyzes multiple approved and emerging therapies based on relevant attributes such as safety, efficacy, frequency of administration, route of administration, and order of entry. Scoring is given based on these parameters to analyze the effectiveness of therapy.

In efficacy, the trial’s primary and secondary outcome measures are evaluated; for instance, in event-free survival, one of the most important primary outcome measures is event-free survival and overall survival.

Further, the therapies’ safety is evaluated wherein the acceptability, tolerability, and adverse events are majorly observed, and it sets a clear understanding of the side effects posed by the drug in the trials. In addition, the scoring is also based on the probability of success, and the addressable patient pool for each therapy. According to these parameters, the final weightage score and the ranking of the emerging therapies are decided.

Market Access and Reimbursement

Life with a family member with PWS can often mean additional expenses for the household, and any further financial help that can be obtained can be useful. Although a diagnosis of PWS does not automatically entitle families to financial support, some allowances can be applied for.

Since 2000, the use of growth hormone has become the standard of care for individuals with PWS. However, growth hormone is a very expensive medication, often costing USD 50,000-USD 60,000 a year at the highest dosage levels. Most families could not even consider growth hormone treatment without excellent insurance coverage or other outside funding. If a family’s insurance policy has an annual or a lifetime cap on benefits, the cost of one child’s growth hormone treatment over a long period could leave insufficient plan benefits for another family member who may need expensive care.

Health insurance plans are allowed to set their requirements for coverage, but usually, they will follow the US FDA approvals. It should not be necessary for a child with PWS to be tested for growth hormone deficiency since the FDA’s decision regarding PWS, effective June 20, 2000. In creating these specific “indications” for children with PWS, the FDA recognized that GHD testing is not a reliable determinant of whether a child with PWS needs growth hormone treatment. Those with PWS only need to show signs of growth failure and have a genetic diagnosis of PWS to qualify for growth hormone treatment under these special Orphan Drug Act approvals. A letter from a doctor to the insurance company might help.

OMNITROPE self-pay program

The OMNITROPE self-pay program is the most comprehensive among daily somatropin injections because it accounts for two formulation options to meet the patient’s needs. Eligible patients may save an average of over USD 5,000 per year vs. wholesale acquisition cost.

OMNITROPE copay savings program

Sandoz is committed to removing obstacles along the patient’s treatment journey. With the copay savings program, eligible patients may pay as little as USD 0 out-of-pocket costs. The up-front benefit provides immediate support for patients starting OMNITROPE. Patients are automatically re-enrolled at the start of each calendar year.

Detailed market access and reimbursement assessment will be provided in the final report.
