## What It Is

Amycretin (now officially named zenagamtide by Novo Nordisk, NNC9204-1177) is a first-in-class unimolecular agonist that simultaneously activates both the glucagon-like peptide-1 (GLP-1) and amylin receptors, developed by Novo Nordisk. Unlike combination therapies, amycretin integrates both mechanisms into a single molecule and is being developed in both subcutaneous and oral formulations. Phase 2 data in type 2 diabetes (n=448, 36 weeks) showed significant results: subcutaneous amycretin achieved up to 14.5% weight loss with HbA1c reductions up to 1.5% (77.6% of participants reaching HbA1c <7%), while the oral formulation achieved dose-dependent weight loss up to 10.1% with HbA1c improvements up to 1.5%. In the Phase 1b/2a obesity trial (published in The Lancet 2025), subcutaneous amycretin achieved approximately 22% weight loss at 36 weeks with no plateau observed. In May 2026, Novo Nordisk expanded the pivotal amycretin program, planning Phase 3 development for type 2 diabetes in addition to the obesity Phase 3 REDEFINE programme that began enrolling in Q1 2026. An FDA filing is expected in late 2026 or early 2027, with a regulatory decision window opening in 2027–2028. The oral formulation is particularly significant, as it could provide dual-agonist efficacy without injections — a major convenience advantage in the competitive obesity market. At the ADA 2026 Scientific Sessions (June 7, New Orleans), Novo Nordisk presented full Phase 2 dose-finding data for zenagamtide in type 2 diabetes — the first randomized controlled evidence of the compound's glycemic efficacy. The 36-week trial randomized 262 adults with type 2 diabetes inadequately controlled on metformin (±SGLT2 inhibitor, A1C 7.0–10.0%) to six doses of subcutaneous zenagamtide (0.4–40 mg once-weekly) or placebo. The 40 mg dose achieved 14.6% mean weight loss and a 1.71 percentage-point reduction in HbA1c — with 89% of participants at the 40 mg dose reaching the ADA's general A1C target of below 7%, and 77.8% achieving ≤6.5%. All doses met the primary endpoint of A1C reduction; weight reduction endpoints were met at doses ≥1.5 mg. Novo Nordisk confirmed plans to initiate a Phase 3 development program for zenagamtide in type 2 diabetes in H2 2026, in addition to the obesity Phase 3 REDEFINE programme already enrolling. The ADA 2026 T2D data establish zenagamtide as the only unimolecular GLP-1/amylin agonist with Phase 2 evidence across both obesity (22% weight loss, Lancet 2025) and type 2 diabetes populations.

Also known as: NNC9204-1177, Zenagamtide

## Regulatory Status

Investigational — Phase 3

Phase 3 REDEFINE programme enrolling for obesity (Q1 2026). Phase 3 for type 2 diabetes initiating H2 2026 (confirmed at ADA 2026, June 7). Phase 2 T2D data (ADA 2026): 14.6% weight loss + HbA1c −1.71% at 40 mg. FDA filing expected late 2026–early 2027.

Effective: Q1 2026

## Why Researchers Study It

Amycretin is notable as the first unimolecular GLP-1/amylin dual agonist, combining two complementary appetite-suppression pathways in a single molecule. The availability of both injectable and oral formulations provides flexibility. Its 22% weight loss at 36 weeks in early studies rivals the best results from GLP-1-only drugs, and the amylin component may offer unique satiety benefits through hypothalamic and area postrema signaling.

## Proposed Mechanisms

- GLP-1 receptor agonism suppresses appetite, slows gastric emptying, and enhances insulin secretion
- Amylin receptor activation promotes satiety through hypothalamus and area postrema signaling
- Dual receptor engagement in a single molecule provides complementary appetite suppression
- Slows gastric emptying through both GLP-1 and amylin pathways
- Improves glycemic control through enhanced insulin sensitivity and secretion
