Overview

About Cagrilintide

Mechanism of action

Long-acting amylin receptor agonist; amylin is co-secreted with insulin; activates amylin receptors in the hypothalamus and brainstem; reduces food intake, slows gastric emptying, reduces body weight; complements GLP-1 mechanisms via separate pathways.

Safety profile

Nausea, vomiting, diarrhea, injection site reactions; generally well-tolerated; similar GI profile to GLP-1 class. Still in trials. · Phase III trials show good tolerability; GI side effects; injection site reactions

Research

Studies & key findings

  • Long-acting fatty-acid-acylated amylin analogue with a 7-day half-life; combined with semaglutide 2.4 mg (CagriSema), produced ~25% mean body weight reduction in REIMAGINE Phase 2/3 — approaching surgical outcomes.
  • Structural studies (2025) revealed cagrilintide engages amylin receptors 1 and 3 in distinct brainstem regions for satiety, complementing GLP-1 receptor engagement by semaglutide for additive weight loss.
