Cagrilintide

Cagri

Amylin AnalogWeight Management

Cagrilintide is a long-acting acylated amylin analog developed by Novo Nordisk for the treatment of obesity and weight management. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells that plays a role in appetite regulation, gastric emptying, and postprandial glucose control. Cagrilintide has been engineered with fatty acid acylation to extend its half-life, enabling once-weekly subcutaneous dosing.,Cagrilintide has been studied as a standalone agent and in combination with semaglutide (the combination known as CagriSema). Phase 2 and Phase 3 clinical trials have demonstrated significant weight loss, with the CagriSema combination showing particularly robust results, achieving greater weight reduction than either agent alone.,As of 2025, cagrilintide is not yet independently FDA-approved, though the CagriSema combination is in late-stage clinical development. Novo Nordisk has filed for regulatory approval of CagriSema. Cagrilintide represents a novel mechanism complementary to GLP-1 receptor agonists, targeting the amylin pathway for appetite and metabolic control.

How it works

Activates amylin receptors (calcitonin receptor plus RAMP1/2/3 complexes) in the area postrema and hypothalamus, promoting satiety and reducing food intake.,Slows gastric emptying, which contributes to prolonged feelings of fullness after meals and reduces postprandial glucose excursions.,May modulate glucagon secretion, reducing hepatic glucose output and contributing to improved glycemic control.
