IMCIVREE (setmelanotide acetate)

Melanocortin 4 Receptor Agonists
First-in-Class Orphan Drug Breakthrough Therapy Priority Review
Metabolic Approved 2020-11-25

IMCIVREE is a melanocortin 4 (MC4) receptor agonist indicated for chronic weight management (to reduce excess body weight and maintain weight reduction long term) in adults and pediatric patients aged 2 years and older with obesity due to: * Bardet-Biedl syndrome (BBS). * Pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency. For POMC, PCSK1, or LEPR deficiency, variants must be confirmed by an FDA-approved test and interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS). IMCIVREE is not indicated for patients with variants classified as benign or likely benign, or for general polygenic obesity.

How IMCIVREE Works

Setmelanotide is an MC4 receptor agonist. MC4 receptors in the brain are key regulators of hunger, satiety, and energy expenditure. In patients with BBS or deficiencies in POMC, PCSK1, or LEPR, the MC4 pathway is insufficiently activated. Setmelanotide re-establishes MC4 receptor pathway activity to reduce food intake (promoting satiety) and increase energy expenditure. The drug also activates MC1 receptors expressed on melanocytes, which can lead to increased skin pigmentation independent of ultraviolet light exposure. It also exhibits minor activity at MC3 receptors.
