Cagrilintide

unknown risk

Also: AM833 · Long-acting amylin

Preliminary Research Only

Cagrilintide is a long-acting amylin analog developed by Novo Nordisk for weight management, primarily in combination with semaglutide (CagriSema). Phase 3 trials are ongoing with promising interim results.

Reported Benefits

Weight Loss

Preliminary 15 studies

Phase 2 SCALE trials showed 15.6% body weight reduction with cagrilintide 2.4mg weekly.

Metabolic Improvement

Preliminary 8 studies

Improved glycemic and lipid markers in Phase 2 studies.

Satiety Enhancement

Preliminary 10 studies

Amylin pathway modulation enhances satiety independently of GLP-1 mechanism.

Mechanism of Action

Cagrilintide is a long-acting analog of amylin (a peptide co-secreted with insulin from pancreatic beta cells). It activates amylin receptors (calcitonin receptor/RAMP complexes) in the hypothalamus and brainstem to suppress appetite, reduce gastric emptying, and inhibit glucagon. Combined with semaglutide, it addresses multiple satiety pathways simultaneously.

Key Clinical Studies

Lau J et al. (2021)

Phase 2 RCT · 706 adults with obesity

Dose-dependent weight loss up to 15.6% at 2.4mg dose

Overview

Cagrilintide represents the amylin arm of Novo Nordisk’s weight management pipeline. The rationale for combining it with semaglutide (GLP-1 agonist) is additive mechanism — addressing satiety through two complementary pathways simultaneously.

CagriSema Combination

The REDEFINE Phase 3 trial program tests cagrilintide 2.4mg + semaglutide 2.4mg weekly. Interim data from Phase 2 showed body weight reductions approaching 25% — potentially the highest pharmacological weight loss efficacy of any compound at time of writing. Phase 3 results are awaited.

Amylin Biology

Amylin is co-secreted with insulin from pancreatic beta cells and acts as a complementary satiety hormone. Pramlintide (Symlin), a shorter-acting amylin analog, is FDA-approved for insulin-using diabetics. Cagrilintide extends this biology to a weekly formulation suitable for combination obesity therapy.

Competitive Landscape

Cagrilintide’s development positions Novo Nordisk to compete in the “next generation” obesity pharmacotherapy space against Eli Lilly’s triple agonist pipeline (retatrutide). The outcome of these Phase 3 programs will significantly shape the obesity treatment market.
