BOSTON, Sept. 28, 2018 (GLOBE NEWSWIRE) -- Rhythm Pharmaceuticals, Inc. (NASDAQ:RYTM), a biopharmaceutical company focused on the development and commercialization of therapeutics for the treatment of rare genetic disorders of obesity, today announced that updated data from the company’s ongoing Phase 2 basket studies evaluating setmelanotide in people with Bardet-Biedl Syndrome (BBS) and Alström Syndrome are being presented at the 57th Annual European Society for Paediatric Endocrinology (ESPE) Meeting held September 27-29, 2018 in Athens, Greece. Results from the studies demonstrate that treatment with setmelanotide led to marked reductions in body weight and decreased appetite as shown by lower hunger scores. Safety data were consistent with previous clinical studies.
“As we continue our mission to improve the understanding of rare genetic disorders of obesity and develop a potentially transformative therapy for people who currently have no treatment options, we are encouraged by our longer-term data with setmelanotide, which show that patients who have been on treatment for many months continue to experience sustained improvements in body weight and appetite,” said Keith Gottesdiener, M.D., Chief Executive Officer of Rhythm. “These studies indicate that both BBS and Alström Syndrome are setmelanotide-responsive, and we look forward to initiating and enrolling the first patients in a combined Phase 3 clinical trial in these indications this year.”
BBS and Alström Syndrome are life-threatening, ultra-rare orphan diseases that are closely related. Both cause severe obesity and insatiable hunger, also known as hyperphagia, that often present during childhood. BBS affects approximately one in 100,000 people in North America and is also associated with vision loss, polydactyly, and kidney abnormalities. Alström Syndrome has a prevalence of approximately one in one million in North America and can lead to progressive vision loss, deafness, cardiomegaly, and insulin resistance. Currently there are no approved therapies for regulating hunger in BBS or Alström Syndrome.
Setmelanotide is a potent, first-in-class melanocortin-4 receptor (MC4R) agonist that is being developed by Rhythm for the treatment of rare genetic disorders of obesity. The U.S. Food & Drug Administration (FDA) has included BBS and Alström Syndrome under a Breakthrough Therapy designation for setmelanotide for the treatment of obesity associated with genetic defects upstream of the MC4R in the leptin-melanocortin pathway. The European Medicines Agency (EMA) 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. In June 2018, Rhythm announced topline clinical data from the ongoing Phase 2 basket studies evaluating setmelanotide in BBS and Alström Syndrome.
Updated Data Presented at 57th Annual ESPE Meeting
In an oral presentation, Robert Haws, M.D., founder of the Marshfield Clinic Research Institute’s BBS program, reported updated data on body weight, hunger scores, and the safety of treatment with setmelanotide in a total of nine patients with BBS as of August 2018:
A separate poster reported updated data on body weight, hunger scores, and the safety of treatment with setmelanotide in one patient with Alström Syndrome as of August 2018. The poster was presented by Joan Han, M.D., director of the Pediatric Obesity Program at Le Bonheur Children’s Hospital and associate professor in the division of pediatric endocrinology at the University of Tennessee Health Science Center:
Setmelanotide is a potent, first-in-class, melanocortin-4 receptor (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 unrelenting hunger and severe, early-onset obesity. Rhythm is currently developing setmelanotide as a replacement therapy for patients with monogenic defects upstream of MC4R, for whom there are no effective or approved therapies. The U.S. Food and Drug Administration has granted Breakthrough Therapy designation to setmelanotide for the treatment of obesity associated with genetic defects upstream of the MC4 receptor in the leptin-melanocortin pathway, which includes POMC deficiency obesity, LEPR deficiency obesity, Bardet-Biedl Syndrome and Alström Syndrome.
Rhythm is a biopharmaceutical company focused on the development and commercialization of therapies for the treatment of rare genetic disorders of obesity. Rhythm is currently evaluating the efficacy and safety of setmelanotide, the Company’s first-in-class melanocortin-4 receptor (MC4R) agonist, in Phase 3 studies in patients with pro-opiomelanocortin (POMC) deficiency obesity (which includes deficiencies in both the POMC and PCSK1 genes) and leptin receptor (LEPR) deficiency obesity. Rhythm also supports The Genetic Obesity Project (www.GeneticObesity.com), which is dedicated to improving the understanding of severe obesity that results from specific genetic disorders. The company is based in Boston, MA.
