BOSTON, March 18, 2020 (GLOBE NEWSWIRE) — Rhythm Pharmaceuticals, Inc. (Nasdaq: RYTM), a late-stage biopharmaceutical company aimed at developing and commercializing therapies for the treatment of rare genetic disorders of obesity, today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to setmelanotide for the treatment Alström syndrome. People living with Alström syndrome may experience an insatiable hunger, also known as hyperphagia, and severe obesity beginning early in life. Rhythm is currently evaluating setmelanotide’s ability to reduce hunger and affect weight loss in an ongoing pivotal Phase 3 trial in patients living with Alström and Bardet-Biedl syndromes.
“Individuals and families living with Alström syndrome face a high disease burden, which often adversely affects their daily lives, and yet there are currently no treatment options available to address this serious unmet need,” said Murray Stewart, M.D., Chief Medical Officer of Rhythm. “Orphan drug designation from the FDA reinforces the urgency of our work with setmelanotide in Alström syndrome, as we advance our pivotal Phase 3 trial to topline data expected by the end of this year or early next year.”Orphan drug designation is granted by the FDA to drugs and biologics that are intended for the safe and effective treatment, diagnosis or prevention of rare diseases or conditions that affect fewer than 200,000 people in the U.S. Orphan drug designation provides certain incentives, which may include tax credits towards the cost of clinical trials and prescription drug user fee waivers.About Alström Syndrome
Alström syndrome is an ultra-rare genetic disorder that affects multiple organ systems. Insatiable hunger, also known as hyperphagia, and severe obesity beginning early in life may be seen in individuals living with Alström syndrome. Clinical features of Alström syndrome may include progressive visual and auditory impairments, insulin resistance and Type 2 diabetes, hyperlipidemia, progressive kidney dysfunction, cardiomyopathy and short stature in adulthood. There is great variability in presentation and severity of these symptoms across individuals with Alström syndrome. In the United States, the Company estimates that Alström syndrome affects approximately 500 people. Currently, there are no approved therapies that restore the impaired function of the melanocortin-4 receptor (MC4R) pathway, a component of the central melanocortin pathway, for reducing body weight and hunger in Alström syndrome.About Setmelanotide
Setmelanotide is a potent MC4R agonist in development for the treatment of rare genetic disorders of obesity. Setmelanotide activates MC4R, part of the key biological pathway that independently regulates energy expenditure and appetite. Variants in genes within the MC4R pathway are associated with insatiable hunger and early-onset, severe obesity. Rhythm is currently developing setmelanotide as a targeted therapy that restores function of an impaired MC4R pathway to reduce weight and hunger in patients for whom there are no effective or approved therapies. The FDA has granted Breakthrough Therapy designation to setmelanotide for the treatment of obesity associated with genetic defects upstream of the MC4 receptor in the central melanocortin pathway, which includes POMC deficiency obesity, LEPR deficiency obesity, Bardet-Biedl syndrome and Alström syndrome. The European Medicines Agency has also granted PRIority MEdicines (PRIME) designation for setmelanotide for the treatment of obesity and the control of hunger associated with deficiency disorders of the MC4R pathway.About Rhythm
Rhythm is a late-stage biopharmaceutical company focused on the development and commercialization of therapies for the treatment of rare genetic disorders of obesity. The company recently announced positive topline results from pivotal Phase 3 clinical trials of setmelanotide, its MC4R agonist, in people living with POMC deficiency obesity and LEPR deficiency obesity and plans to complete its first rolling NDA submission to the FDA in the first quarter of 2020. Rhythm is also evaluating setmelanotide in a pivotal Phase 3 trial in people living with Bardet-Biedl and Alström syndromes, with topline data from this trial expected in the fourth quarter of 2020 or early in the first quarter of 2021. Rhythm is leveraging the Rhythm Engine — comprised of its Phase 2 basket study, TEMPO Registry, GO-ID genotyping study and Uncovering Rare Obesity program — to improve the understanding, diagnosis and potentially the treatment of rare genetic disorders of obesity.
