Amycretin
Metabolic / Weight LossAlso known as: NNC0487-0111, Novo Nordisk Amycretin
Mechanism
Amycretin is a next-generation weight loss peptide from Novo Nordisk that activates both GLP-1 and amylin receptors in a single molecule. This dual action suppresses appetite through two complementary pathways — GLP-1 slows gastric emptying and enhances insulin release, while amylin acts on the brainstem to reduce hunger. Early trials show potentially greater weight loss than semaglutide alone.
Technical detail
Amycretin is a unimolecular dual GLP-1R/amylin receptor (AMYR) co-agonist designed as a single peptide chain activating both receptor systems. GLP-1R agonism drives incretin-mediated insulin secretion, suppression of glucagon release, and delayed gastric emptying via vagal afferents. AMYR agonism (calcitonin receptor + RAMP1/2/3 heterodimers) activates area postrema neurons to produce satiety signaling and reduces glucagon secretion. The combined mechanism targets both peripheral metabolic and central appetite regulatory pathways.

First-in-human randomized placebo-controlled study found oral amycretin generally safe and tolerable in overweight/obesity, with dose-proportional pharmacokinetics and mostly mild-to-moderate gastrointestinal adverse events supporting continued development.

Phase 1b/2a randomized study in 125 participants with overweight/obesity found substantial placebo-adjusted weight loss with weekly subcutaneous amycretin, reaching -24.3% at 60 mg over 36 weeks, with gastrointestinal adverse events mostly mild to moderate.
