-- Further Improvements Observed in Bardet-Biedl Syndrome Patients; Initial Proof-of-Concept Data in Alström Syndrome Demonstrates Significant Weight Loss and Decreased Hunger -- BOSTON, June 18, 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 new topline clinical data from its ongoing Phase 2 basket studies of setmelanotide, a first-in-class melanocortin-4 receptor (MC4R) agonist, including updated data in patients with Bardet-Biedl Syndrome (BBS), initial proof-of-concept data in Alström Syndrome, and promising, preliminary data in pro-opiomelanocortin (POMC) and other MC4 pathway heterozygous deficiency obesities, as well as in POMC epigenetic disorders. Across all these rare genetic disorders of obesity, setmelanotide was observed to be well-tolerated. “Despite growing awareness around rare genetic disorders of obesity, people living with these conditions are underserved by currently available treatments, which have limited efficacy and fail to address underlying disease biology,” said Robert M. Haws, M.D., Medical Director of Clinical Research at the Marshfield Clinic Research Foundation and an investigator in the study. “I, along with my other research collaborators, continue to study setmelanotide’s ability to curb excess hunger and reverse early-onset obesity, and we are encouraged by the updated data in BBS announced today. We are eager to continue studying the use of setmelanotide in a Phase 3 trial in BBS and Alström Syndrome.” “These new clinical data build upon prior clinical experience and reinforce our confidence in setmelanotide as a potentially transformative treatment option,” said Keith Gottesdiener, M.D., Chief Executive Officer of Rhythm Pharmaceuticals. “With these results in hand, we are advancing our broad clinical development program for setmelanotide with optimism. We are particularly pleased to progress setmelanotide into a combined Phase 3 program in BBS and Alström Syndrome, which joins our fully-enrolled POMC and leptin receptor (LEPR) deficiency obesity trials as our third pivotal-stage trial. Based on recent interactions with the U.S. Food and Drug Administration (FDA), we have guidance for a combined trial in BBS and Alström Syndrome. This will enable us to evaluate setmelanotide simultaneously in these two rare genetic disorders of obesity that we believe share a similar pathophysiology and clinical presentation, which could potentially enable a more rapid path to regulatory filing. We also plan to enroll additional patients with POMC and other MC4 pathway heterozygous deficiency obesities, as well as POMC epigenetic disorders, in our ongoing Phase 2 basket studies in order to better understand the magnitude of setmelanotide’s effect and to inform our next steps.” New Topline Clinical Data From Ongoing Phase 2 Basket Studies Maturing Data Demonstrate Improved Efficacy in BBS:
Proof-of-Concept Achieved in Alström Syndrome:
Initial Positive Results Observed in POMC and other MC4 Pathway Heterozygous Deficiency Obesities:
Initial Positive Results Observed in POMC Epigenetic Disorders:
Consistent with prior clinical experience, treatment with setmelanotide was observed to be well-tolerated. The majority of adverse events reported by investigators were mild, primarily injection site reactions and increased skin pigmentation. Clinical Development Plans for Setmelanotide in BBS and Alström Syndrome Following recent discussions with the FDA, Rhythm plans to initiate a combined pivotal Phase 3 trial evaluating setmelanotide in patients with BBS and Alström Syndrome. Rhythm expects this open-label, single-arm, multinational trial to evaluate the safety and efficacy of setmelanotide in at least 20 BBS patients and at least six Alström Syndrome patients, aged six years and older, with setmelanotide administered once daily by subcutaneous injection for approximately 12 months. The trial will begin with an initial period of dose titration, using a simplified titration scheme. The trial may also include a 12-week, randomized, placebo-controlled period, after which all patients will complete an additional period of active setmelanotide treatment to complete the one-year trial. Rhythm is continuing discussions with the FDA to finalize the trial design, protocol and endpoints, and expects to initiate the trial and enroll the first patients by the end of 2018. Clinical Development Plans for Setmelanotide in POMC and other MC4 Pathway Heterozygous Deficiency Obesities and POMC Epigenetic Disorders Rhythm intends to continue enrolling patients with POMC and other MC4 pathway heterozygous deficiency obesities, as well as POMC epigenetic disorders, in its ongoing Phase 2 basket studies, in order to identify those patients most likely to benefit from setmelanotide treatment. The Company expects to announce updated data from a larger number of patients with POMC and other MC4 pathway heterozygous deficiency obesities, as well as POMC epigenetic disorders in the first quarter of 2019. About Setmelanotide 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. About Rhythm Pharmaceuticals 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. Forward-Looking Statements Investor Contact: Media Contact: |
