BOSTON, June 16, 2022 (GLOBE NEWSWIRE) -- Rhythm Pharmaceuticals, Inc. (Nasdaq: RYTM), a commercial-stage biopharmaceutical company committed to transforming the care of people living with rare genetic diseases of obesity, today announced that the U.S. Food and Drug Administration (FDA) has approved the Company’s supplemental New Drug Application (sNDA) for IMCIVREE® (setmelanotide), a melanocortin-4 receptor (MC4R) agonist, for patients with Bardet-Biedl syndrome (BBS).

With today’s approval, IMCIVREE is indicated for chronic weight management in adult and pediatric patients 6 years old and older with monogenic or syndromic obesity due to proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1) or leptin receptor (LEPR) deficiency, or BBS.

“This FDA approval represents a significant milestone for Rhythm, validating our strategy of developing IMCIVREE for people with hyperphagia and severe obesity caused by rare MC4R-pathway diseases and allowing us to provide our precision therapy to an established community of patients living with BBS and their families who are eagerly awaiting a new treatment option,” said David Meeker, M.D., Chair, President and Chief Executive Officer of Rhythm. “Leveraging the robust infrastructure we put in place following the initial approval of IMCIVREE for obesity due to biallelic POMC, PCSK1 or LEPR deficiency and our new high-touch patient support services to assist patients throughout the journey from diagnosis to ongoing treatment, we are able to make IMCIVREE available for BBS immediately. We look forward to delivering this important medicine to the growing community of patients and families in need of options that can effectively address the obesity and hyperphagia that affect many people living with BBS.”

IMCIVREE was initially approved by the FDA in November 2020 for chronic weight management in adult and pediatric patients 6 years of age and older with obesity due to POMC, PCSK1 or LEPR deficiency. IMCIVREE’s label was updated today to include an FDA-approved test developed under a post-marketing commitment to confirm variants in POMC, PCSK1 or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS).

IMCIVREE is not indicated for the treatment of patients with obesity due to suspected POMC, PCSK1 or LEPR deficiency with POMC, PCSK1 or LEPR variants classified as benign or likely benign, or other types of obesity not related to POMC, PCSK1 or LEPR deficiency, or BBS, including obesity associated with other genetic syndromes and general (polygenic) obesity.

In clinical trials, IMCIVREE was generally well-tolerated. Disturbance in sexual arousal, depression and suicidal ideation, increased skin pigmentation and darkening of pre-existing nevi, and benzyl alcohol toxicity in neonates and low birth-weight infants may occur. The most common adverse reactions were skin hyperpigmentation, injection site reactions and nausea.

BBS is a rare genetic disease that affects approximately 1,500-2,500 people in the U.S. People living with BBS may experience insatiable hunger, also known as hyperphagia, and severe obesity beginning early in life. BBS may also be associated with cognitive impairment, polydactyly, renal dysfunction, hypogonadism, and visual impairment.

Robert Haws, M.D., a BBS expert who recently retired from his role as Director of the Center of Excellence for Bardet-Biedl Syndrome at the Marshfield Clinic Research Institute in Wisconsin, said, “This approval marks an important achievement for the entire BBS community including patients and their families, clinicians and researchers, as we all have been looking forward to a therapy that addresses the burdens of hyperphagia and severe obesity that significantly affect daily lives of patients and caregivers living with BBS. IMCIVREE achieved significant reductions in weight and hunger in patients with BBS, providing this community a much needed and first-ever therapeutic option.”

“It is important to understand that the early-onset, severe obesity and pathologic hunger experienced by many people living with BBS can be debilitating, especially when you consider the impact of food-seeking behavior on families,” said Timothy Ogden, President, BBS Foundation and Family Association. “Challenges in managing weight and hunger have dramatically negative effects on health, well-being, and quality of life for those living with BBS, and we are thrilled finally to have a new treatment option to address this significant unmet need.”

Data from Phase 3 trial evaluating IMCIVREE in BBS

The FDA application for IMCIVREE was based on data from Rhythm’s pivotal Phase 3 clinical trial, which was the largest and longest interventional clinical trial in BBS. In the clinical trial, IMCIVREE delivered early, significant and sustained weight reduction. The trial met its primary endpoint and all key secondary endpoints, with statistically significant reductions in weight and hunger at 52 weeks on therapy.

As presented in the label, in patients aged ≥6 years with obesity due to BBS (N=31):

  • Mean percent change in BMI was -7.9% without requirements for diet and exercise;
  • Placebo-adjusted change in BMI was -4.5% in a 14-week double-blind placebo-controlled stage (IMCIVREE n=22; -4.6% change in BMI; placebo n=22; -0.1% change in BMI); and
  • Statistically significant mean change in hunger score was -2.1 at 52 weeks in patients 12 years and older who were able to self-report their hunger (n=14).

Rhythm also announced that the FDA issued a complete response letter for the sNDA for setmelanotide in Alström syndrome. Rhythm plans to reevaluate potential paths forward in Alström syndrome in the U.S.

“We appreciate the FDA’s careful review of our sNDA for IMCIVREE for the treatment of Alström syndrome, but are disappointed in this outcome,” added Dr. Meeker. “We are tremendously grateful to the Alström syndrome patients, caregivers and physicians who participated in our clinical development efforts and look forward to providing an update regarding our path forward.”

Rhythm InTune offers personalized support to patients, caregivers and physicians

Today, the Company also announced the launch of Rhythm InTune, a program that provides personalized support for individuals living with rare genetic diseases of obesity. Rhythm InTune provides education and resources tailored to fit each patient’s unique need, with a dedicated patient education manager as a single point of contact.

About Setmelanotide

Setmelanotide is a melanocortin-4 receptor (MC4R) agonist. The MC4R is part of the key biological pathway that regulates hunger, caloric intake and energy expenditure. Variants in genes may impair the function of the MC4R pathway, potentially leading to hyperphagia and early-onset, severe obesity. Rhythm is developing setmelanotide as a targeted therapy to potentially restore the function of an impaired MC4R pathway and, in so doing, potentially reduce hunger and weight in patients with rare genetic diseases of obesity.

In the EU and Great Britain, IMCIVREE is indicated for the treatment of obesity and the control of hunger associated with genetically confirmed loss-of-function biallelic POMC, including PCSK1, deficiency or biallelic LEPR deficiency in adults and children 6 years of age and above. IMCIVREE should be prescribed and supervised by a physician with expertise in obesity with underlying genetic etiology.

Rhythm’s Type II variation application to the European Medicines Agency (EMA) for the treatment of obesity and control of hyperphagia in adult and pediatric patients 6 years of age and older with BBS is under review. The Company is also continuing to advance the most comprehensive clinical research program ever initiated in MC4R pathway diseases, including the pivotal Phase 3 EMANATE clinical trial evaluating setmelanotide in four independent sub-studies in patients with obesity due to POMC insufficiency caused by heterozygous variants in the POMC or PCSK1 genes, LEPR insufficiency caused by heterozygous variants in the LEPR gene, SRC1 deficiency caused by a variant in the NCOA1 gene, and SH2B1 deficiency caused by a variant in the SH2B1 gene or 16p11.2 deletion encompassing the SH2B1 gene. The Phase 2 DAYBREAK trial is evaluating setmelanotide in patients with severe obesity and hyperphagia caused by rare variants associated with 10 prioritized MC4R-relevant genes. Rhythm has also initiated a Phase 3 pediatric trial and a Phase 3 trial evaluating a weekly formulation of setmelanotide.

IMCIVREE® (setmelanotide) Indication

In the United States, IMCIVREE is indicated for chronic weight management in adult and pediatric patients 6 years of age and older with monogenic or syndromic obesity due to:

  • Pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1) or leptin receptor (LEPR) deficiency as determined by an FDA-approved test demonstrating variants in POMC, PCSK1 or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS)
  • Bardet-Biedl syndrome (BBS)

Limitations of Use

IMCIVREE is not indicated for the treatment of patients with the following conditions as IMCIVREE would not be expected to be effective:

  • Obesity due to suspected POMC, PCSK1 or LEPR deficiency with POMC, PCSK1 or LEPR variants classified as benign or likely benign
  • Other types of obesity not related to POMC, PCSK1 or LEPR deficiency, or BBS, including obesity associated with other genetic syndromes and general (polygenic) obesity

WARNINGS AND PRECAUTIONS

Disturbance in Sexual Arousal: Spontaneous penile erections in males and sexual adverse reactions in females have occurred. Inform patients that these events may occur and instruct patients who have an erection lasting longer than 4 hours to seek emergency medical attention.

Depression and Suicidal Ideation: Depression and suicidal ideation have occurred. Monitor patients for new onset or worsening depression or suicidal thoughts or behaviors. Consider discontinuing IMCIVREE if patients experience suicidal thoughts or behaviors, or clinically significant or persistent depression symptoms occur.

Skin Pigmentation and Darkening of Pre-existing Nevi: Generalized increased skin pigmentation and darkening of pre-existing nevi have occurred. Perform a full body skin examination prior to initiation and periodically during treatment to monitor pre-existing and new pigmentary lesions.

Risk of Serious Adverse Reactions Due to Benzyl Alcohol Preservative in Neonates and Low Birth Weight Infants: IMCIVREE is not approved for use in neonates or infants. Serious and fatal adverse reactions including “gasping syndrome” can occur in neonates and low birth weight infants treated with benzyl alcohol-preserved drugs.

ADVERSE REACTIONS

  • The most common adverse reactions (incidence ≥20%) included skin hyperpigmentation, injection site reactions, nausea, headache, diarrhea, abdominal pain, vomiting, depression, and spontaneous penile erection.

USE IN SPECIFIC POPULATIONS

Treatment with IMCIVREE is not recommended when breastfeeding. Discontinue IMCIVREE when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus.
