OR10-1 Body Mass Index and Weight Reductions in Patients With Obesity Due to Heterozygous Variants in POMC, PCSK1, and LEPR After 1 Year of Setmelanotide

ABSTRACT: Abstract

Background

The melanocortin-4 receptor (MC4R) pathway is a key regulator of energy balance. Heterozygous variants of the genes for proopiomelanocortin (POMC), leptin receptor (LEPR), and proprotein convertase subtilisin/kexin type 1 (PCSK1) upstream of MC4R can result in impaired signaling in the MC4R pathway. This impaired signaling can lead to hyperphagia and early-onset, severe obesity. Setmelanotide (SET), an MC4R agonist, reduced weight and hunger after 3 months in patients with obesity due to these heterozygous variants in an earlier Phase 2 study. The current analysis is the first to assess continued efficacy of an additional year of SET treatment in patients with obesity due to heterozygous affectation of POMC, PCSK1, and LEPR.
