Overview
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...
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Setmelanotide is an MC4 receptor agonist with 20-fold less activity at the melanocortin 3 (MC3) and melanocortin 1 (MC1) receptors. MC4 receptors in the brain are involved in regulation of hunger, satiety, and energy expenditure. Based on nonclinical evidence, setmelanotide may re establish MC4 receptor pathway activity to reduce food intake and promote weight loss through decreased caloric intake and increased energy expenditure in patients with obesity due to acquired HO, BBS, or POMC, PCSK1, or LEPR deficiency associated with insufficient activation of the MC4 receptor.
Indications
- 1 INDICATIONS AND USAGE IMCIVREE is indicated to reduce excess body weight and maintain weight reduction long term in adults and pediatric patients aged [ see Dosage and Administration (2.1) ]: 4 years and older with acquired hypothalamic obesity (HO) 2 years and older with syndromic or monogenic obesity due to: o Bardet-Biedl syndrome (BBS) o Pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency confirmed by genetic testing demonstrating variants in POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely...
