Description
11 DESCRIPTION IMCIVREE contains setmelanotide acetate, a melanocortin 4 (MC4) receptor agonist. Setmelanotide is an 8 amino acid cyclic peptide analog of endogenous melanocortin peptide α-MSH (alpha-melanocyte stimulating hormone). The chemical name for setmelanotide acetate is acetyl-L-arginyl-L-cysteinyl-D-alanyl-L-histidinyl-D-phenylalanyl-L-arginyl-L-tryptophanyl-L-cysteinamide cyclic (2→8)-disulfide acetate. Its molecular formula is C 49 H 68 N 18 O 9 S 2 (anhydrous, free-base), and molecular mass is 1117.3 Daltons (anhydrous, free-base). The chemical structure of setmelanotide acetate is: IMCIVREE (setmelanotide) injection is a sterile clear to slightly opalescent, colorless to slightly yellow solution for subcutaneous use. Each 1 mL single-patient use vial of IMCIVREE contains 10 mg of setmelanotide provided as setmelanotide acetate, which is a salt with 2 to 4 molar equivalents of acetate, and the following inactive ingredients: 10 mg benzyl alcohol, 8 mg carboxymethylcellulose sodium (average MWt 90,500), 1 mg edetate disodium dihydrate, 100 mg N-(carbonyl-methoxypolyethylene glycol 2000)-1,2-distearoyl- glycero-3- phosphoethanolamine sodium salt, 11 mg mannitol, 5 mg phenol, hydrochloric acid, sodium hydroxide and Water for Injection. The pH of IMCIVREE is 5 to 6. CHEMICAL-STRUCTURES
What Is Setmelanotide Used For?
1 INDICATIONS AND USAGE IMCIVREE is indicated to reduce excess body weight and maintain weight reduction long term in adults and pediatric patients aged 2 years and older with syndromic or monogenic obesity due to: Bardet-Biedl syndrome (BBS) [see Dosage and Administration ( 2.1 )] 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) [see Dosage and Administration ( 2.1 )]. 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 BBS or POMC, PCSK1, or LEPR deficiency, including obesity associated with other genetic syndromes and general (polygenic) obesity IMCIVREE is a melanocortin 4 (MC4) receptor agonist indicated to reduce excess body weight and maintain weight reduction long term in adults and pediatric patients 2 years of age and older with syndromic or monogenic obesity due to: Bardet-Biedl syndrome (BBS).

( 2.2 , 2.3 , 2.4 , 2.5 , 2.6 ) 2.1 Patient Selection BBS Select patients for treatment with IMCIVREE who have a clinical diagnosis of BBS [see Clinical Studies ( 14 )]. Consider genetic confirmation in pediatric patients aged <6 years. POMC, PCSK1, or LEPR Deficiency Select patients for treatment with IMCIVREE who have genetically determined or suspected deficiency of POMC, PCSK1, or LEPR [see Clinical Studies ( 14 )]. Treat patients with variants in POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS) in the clinical context of the patient [see Clinical Studies ( 14 )].

Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Disturbance in Sexual Arousal [see Warnings and Precautions ( 5.1 )] Depression and Suicidal Ideation [see Warnings and Precautions ( 5.2 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.3 )] Skin Hyperpigmentation, Darkening of Pre-Existing Nevi, and Development of New Melanocytic Nevi [see Warnings and Precautions ( 5.4 )] Most common adverse reactions (incidence ≥20%) included skin hyperpigmentation, injection site reactions, nausea, headache, diarrhea, abdominal pain, vomiting, depression, and spontaneous penile erection. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Rhythm Pharmaceuticals at 1-833-789-6337 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Bardet-Biedl Syndrome (Adults and Pediatric Patients Aged 6 Years and Older) The safety of IMCIVREE was evaluated in a clinical study, which included a 14 week, randomized, double-blind, placebo-controlled period followed by a 52-week open-label, treatment period, in 44 patients aged 6 years and older with obesity and a clinical diagnosis of BBS (Study 1) [see Clinical Studies ( 14 )]. The study duration was 66 weeks. During the 14-week placebo-controlled period in Study 1, the most common reported adverse reactions in IMCIVREE-treated patients when compared to placebo-treated patients were hyperpigmentation disorders (67% vs 0%, respectively) and vomiting (11% vs 0%, respectively). Adverse reactions were also evaluated during the 52-week active-treatment period, defined as the period from randomization to Week 52 in patients initially randomized to IMCIVREE, and from Week 14 to Week 66 in patients initially randomized to placebo. Table 3 summarizes the adverse reactions that occurred in 2 or more IMCIVREE-treated patients in Study 3 during the 52-week active treatment period.

Contraindications
4 CONTRAINDICATIONS IMCIVREE is contraindicated in patients with a prior serious hypersensitivity reaction to setmelanotide or any of the excipients in IMCIVREE. Serious hypersensitivity reactions have included anaphylaxis [see Warnings and Precautions ( 5.3 )]. Prior serious hypersensitivity to setmelanotide or any of the excipients in IMCIVREE ( 4 )
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Discontinue IMCIVREE when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus. IMCIVREE contains the preservative benzyl alcohol. Because benzyl alcohol is rapidly metabolized by a pregnant woman, benzyl alcohol exposure in the fetus is unlikely. However, adverse reactions have occurred in premature neonates and low birth weight infants who received intravenously administered benzyl alcohol-containing drugs [see Warnings and Precautions ( 5.5 ) and Use in Specific Populations ( 8.4 )]. There are no available data with IMCIVREE in pregnant women to inform a drug-associated risk for major birth defects and miscarriage, or adverse maternal or fetal outcomes. For the general US population, weight loss offers no potential benefit to a pregnant woman and may result in fetal harm (see Clinical Considerations ) . In animal reproduction studies, setmelanotide subcutaneously administered to pregnant rats from before mating to the end of organogenesis was not teratogenic at doses 11 times the maximum recommended human dose (MRHD) of 3 mg. Setmelanotide subcutaneously administered to pregnant rabbits during the period of organogenesis was not teratogenic at clinical doses. Setmelanotide administered subcutaneously to pregnant rats during organogenesis through lactation did not result in adverse developmental effects at doses 7 times the MRHD ( see Data ). The estimated background risk of birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risks Maternal obesity increases the risk for congenital malformations, including neural tube defects, cardiac malformations, oral clefts, and limb reduction defects. In addition, weight loss during pregnancy may...
Overdosage
10 OVERDOSAGE In the event of an overdose initiate appropriate supportive treatment according to the patient’s clinical signs and symptoms.
