Rhythm Pharmaceuticals Advances Setmelanotide for Rare Obesity

Rhythm Pharmaceuticals Makes Strides with Setmelanotide

Rhythm Pharmaceuticals, Inc. (NASDAQ: RYTM), a company dedicated to transforming the lives of patients living with rare neuroendocrine diseases, has received significant news that impacts its pipeline treatment. The U.S. Food and Drug Administration (FDA) has accepted for filing the company's supplemental New Drug Application (sNDA) for setmelanotide, aimed at treating conditions associated with acquired hypothalamic obesity. The FDA has also granted a Priority Review for this application, highlighting the treatment's potential urgency and importance in addressing unique patient needs.

Priority Review and PDUFA Date

The FDA has assigned a Prescription Drug User Fee Act (PDUFA) goal date of December 20, 2025. This reflects the agency's recognition of the clinical needs that setmelanotide addresses and the seriousness of the condition it aims to treat. The acceptance of the sNDA sets the stage for possible market entry of this vital treatment, which is designed for patients coping with the challenges posed by acquired hypothalamic obesity.

EMA Validation and Ongoing Reviews

In parallel, Rhythm Pharmaceuticals announced validation from the European Medicines Agency (EMA) regarding its Type II variation submission to the Marketing Authorization Application (MAA) for setmelanotide. The significance of this validation cannot be understated, as it not only confirms the application’s adequacy for review but also signifies the potential for broader access to this treatment across Europe.

Significance of Setmelanotide

Setmelanotide is a melanocortin-4 receptor (MC4R) agonist previously approved as IMCIVREE. This innovative treatment has shown effectiveness for patients with specific genetic disorders related to obesity, such as Bardet-Biedl syndrome and various deficiencies (POMC, PCSK1, or LEPR). The recent focus on acquired hypothalamic obesity showcases a crucial expansion of setmelanotide's indications, helping to meet the needs of a patient population with otherwise limited treatment options.

Clinical Trials Support Efficacy

The sNDA and Type II Variation submission are underpinned by compelling data from the Phase 3 TRANSCEND trial, which involved 120 patients with acquired hypothalamic obesity. The results from the study, discussed at the Endocrine Society's Annual Meeting, highlighted a remarkable -19.8% placebo-adjusted reduction in body mass index (BMI). This significant finding illustrates the effectiveness of setmelanotide, especially in patients who face unique challenges such as heightened hunger and reduced energy expenditure due to hypothalamic injury.

Patient Outcomes and Tolerability

Participants receiving setmelanotide therapy experienced notable reductions in BMI, with certain demographics showing higher efficacy. Adult patients registered an approximate -19.2% placebo-adjusted reduction in BMI at 52 weeks, while pediatric patients achieved an approximate -20.2% reduction. The overall safety profile from the TRANSCEND trial indicates that setmelanotide is generally well tolerated, with some patients experiencing common treatment-emergent adverse events such as nausea, vomiting, and injection site reactions.

Upcoming Investor Event

In the spirit of transparency and engagement with stakeholders, Rhythm will host a dedicated event titled "Commercial Readiness for Acquired Hypothalamic Obesity." Scheduled for September 24, 2025, this event aims to provide insights into market launch plans, regulatory progress, and the urgent patient need for effective treatment solutions. The event will feature perspectives from leading physicians who underscore the critical need for advancements in treatment for patients struggling with this condition.

Understanding Acquired Hypothalamic Obesity

This rare form of obesity arises from physical injury or structural abnormalities affecting the hypothalamus, disrupting the MC4R pathway. Patients typically face severe challenges such as increased hunger and reduced energy expenditure, leading them to gain weight rapidly after the onset of their condition. Understanding the nature of acquired hypothalamic obesity and its far-reaching impact on affected individuals is essential for developing effective therapies like setmelanotide.

Rhythm Pharmaceuticals' Commitment

Rhythm Pharmaceuticals is dedicated to advancing innovative treatments that positively influence the lives of patients and families dealing with rare neuroendocrine disorders. With setmelanotide, the company is taking a significant step toward providing effective solutions to those affected by significant obesity-related challenges—not only in the U.S. but also in European territories.
