Research

Class:

MC4R (melanocortin-4 receptor) agonist (8-amino-acid cyclic peptide)

Status:

FDA-approved (Imcivree 2020) — orphan drug for genetic obesity

Mechanism:

A first-in-class, 8-amino-acid cyclic peptide (Ac-Arg-cyclo[Cys-D-Ala-His-D-Phe-Arg-Trp-Cys]-NH2) that acts as a selective MC4R agonist. MC4R is a key regulator of hunger, satiety, and energy expenditure in the hypothalamus. Setmelanotide restores melanocortin signaling in patients with genetic defects in the leptin-melanocortin pathway, producing significant weight loss without cardiovascular side effects.
