Rhythm Pharmaceuticals Presents First-ever Data Showing Improvements in Health-related Quality of Life for Patients Living with Bardet-Biedl Syndrome at ObesityWeek® 2021
-- Additional oral presentation details safety and efficacy data from Phase 3 trial of setmelanotide in BBS --
-- Also presenting new hunger data from SRC1 and SH2B1 cohorts in Phase 2 Basket Trial and new data on utilization of URO® genetic testing program –
Also at ObesityWeek®, the company shared an oral presentation detailing efficacy and safety data from its Phase 3 trial of setmelanotide in BBS and Alström syndrome, as well as poster presentations with new hunger reduction data from the SRC1 and SH2B1 genetic deficiency cohorts in its exploratory Phase 2 Basket Trial. Additional presentations include new data on utilization of the Uncovering Rare Obesity® (URO) genetic testing program, an analysis of the frequency of melanocortin-4 receptor (MC4R) pathway variants in
“We are excited to share multiple presentations at ObesityWeek, which demonstrate continued progress toward our goal of transforming the care of people living with rare genetic diseases of obesity,” said
Setmelanotide in BBS: HRQOL and Efficacy and Safety Data
- 85% of patients reported clinically meaningful improvements in their HRQOL status after one year of setmelanotide therapy, or preserved their non-impaired HRQOL status;
- For adult patients, changes in their IWQOL score were clinically meaningful with a mean increase of 12 points after one year on setmelanotide therapy from 74.9 at baseline;
- In pediatric patients, changes in their PedsQL score were clinically meaningful with a mean increase of 11.2 after one year on setmelanotide therapy from 67.2 at baseline;
- For the subset of patients without cognitive impairment, clinically meaningful improvements in outcomes such as body mass index and hunger mirrored their improvements in HRQOL;
- HRQOL improvements were sustained over the 52-week trial period.
- Patients 18 years old or older (n=15) achieved a mean reduction in BMI of 9.1% from baseline 46.4 kg/m2; and
- Patients younger than 18 years (n=16) achieved a mean reduction in BMI of 9.5% from baseline 37.4 kg/m2.
Setmelanotide Therapy Achieved Hunger Reductions in SH2B1 and SRC1 Deficiency Obesities
Rhythm also presented new hunger reduction data from its exploratory Phase 2 Basket Trial evaluating setmelanotide in patients with obesity due to variants of the SRC1 gene or the SH2B1 gene.
In addition to confirming that patients with SRC1 deficiency or SH2B1 deficiency experience severe obesity beginning at a young age, data from these cohorts demonstrated that three months of setmelanotide therapy resulted in reductions in most hunger scores in patients 12 years old and older, regardless of whether the patients met the study definition of weight responder.1
At the 59th Annual
Additional Rhythm poster presentations at ObesityWeek include:
Ida Moeller, ScD, ScM, MMSc, Director of Biomedical Informatics at Rhythm, presented, “Frequency of MC4R pathway variants in a large US cohort of patients with severe obesity;” Jill Garrison, Ph.D., Associate Director, Medical Affairs, at Rhythm, presented, “Uncovering Rare Obesity Genetic Testing Program: Overview and Health Care Provider Utilization;” and Megan Vogel, Ph.D., Scientist, Pre-Clinical Biology at Rhythm, presented, “Biochemical Characterization of Single Minded-1 Missense Variants Associated with Severe Obesity.”
All Rhythm’s presentations from ObesityWeek will be available on the Publication and Presentations section of its website: https://www.rhythmtx.com/publications/
1A responder was defined as having ≥5% weight loss in those ≥18 years old or ≥0.15 reduction in BMI Z score in those <18 years old.
About Rhythm Pharmaceuticals
Rhythm is a commercial-stage biopharmaceutical company committed to transforming the treatment paradigm for people living with rare genetic diseases of obesity. Rhythm’s precision medicine, IMCIVREE (setmelanotide), was approved in November 2020 by the U.S. Food and Drug Administration (FDA) for chronic weight management in adult and pediatric patients 6 years of age and older with obesity due to POMC, PCSK1 or LEPR deficiency confirmed by genetic testing and in July and September 2021, respectively, by the European Commission (EC) and Great Britain’s Medicines & Healthcare Products Regulatory Agency (MHRA) 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 is the first-ever FDA-approved and EC- and MHRA-authorized therapy for patients with these rare genetic diseases of obesity. The Company submitted a supplemental New Drug Application (sNDA) to the FDA in
Additionally, Rhythm is advancing a broad clinical development program for setmelanotide in other rare genetic diseases of obesity and is leveraging the Rhythm Engine and the largest known obesity DNA database -- now with approximately 37,500 sequencing samples -- to improve the understanding, diagnosis and care of people living with severe obesity due to certain genetic deficiencies. Rhythm’s headquarters is in Boston, MA.
IMCIVREE® (setmelanotide) Indication
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.
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, including obesity associated with other genetic syndromes and general (polygenic) obesity.
Important Safety Information
WARNINGS AND PRECAUTIONS
Disturbance in Sexual Arousal: Sexual adverse reactions may occur in patients treated with IMCIVREE. Spontaneous penile erections in males and sexual adverse reactions in females occurred in clinical studies with IMCIVREE. Instruct patients who have an erection lasting longer than 4 hours to seek emergency medical attention.
Depression and Suicidal Ideation: Some drugs that target the central nervous system, such as IMCIVREE, may cause depression or suicidal ideation. Monitor patients for new onset or worsening of depression. Consider discontinuing IMCIVREE if patients experience suicidal thoughts or behaviors.
Skin Pigmentation and Darkening of Pre-Existing Nevi: IMCIVREE may cause generalized increased skin pigmentation and darkening of pre-existing nevi due to its pharmacologic effect. This effect is reversible upon discontinuation of the drug. Perform a full body skin examination prior to initiation and periodically during treatment with IMCIVREE to monitor pre-existing and new skin 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.
- The most common adverse reactions (incidence ≥23%) were injection site reactions, skin hyperpigmentation, nausea, headache, diarrhea, abdominal pain, back pain, fatigue, vomiting, depression, upper respiratory tract infection, and spontaneous penile erection.
USE IN SPECIFIC POPULATIONS
Discontinue IMCIVREE when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus.
Treatment with IMCIVREE is not recommended for use while breastfeeding.
