Incretin mimetics have revolutionized the treatment of obesity and type 2 diabetes. These therapies have shown remarkable efficacy in promoting weight loss and improving glucose metabolism and cardiometabolic health. However, a significant drawback of these therapies is the concurrent loss of lean body mass (LBM), which can account for a substantial overall weight reduction (15% to 40%). The reduction in LBM affects resting metabolic rate, often leading to a weight loss plateau and other negative outcomes.
Investigators from 35Pharma Inc. carried out in vivo testing of HS-135, an activin-receptor-based fusion protein (ActRIIB ligand trap), focusing on target engagement, effect on body composition and efficacy in pulmonary arterial hypertension (PAH).
