Overview

A synthetic analog of amylin, a peptide hormone co-secreted with insulin by pancreatic beta cells. FDA-approved as an adjunct to insulin therapy in type 1 and type 2 diabetes. Represents the amylin pathway that cagrilintide (investigational) also targets.

A long-acting amylin analog developed by Novo Nordisk. Amylin is a hormone co-secreted with insulin that regulates appetite and gastric emptying. Being developed both standalone and in combination with semaglutide (CagriSema) — a combination showing weight loss exceeding 22% in Phase 3 trials, potentially the next step beyond tirzepatide.

Mechanism of Action

Mimics the effects of amylin: slows gastric emptying, suppresses postprandial glucagon secretion, and promotes satiety. These effects complement insulin therapy by reducing postprandial glucose spikes and caloric intake.

Activates amylin receptors (CALCR/RAMP) in the brain, particularly in the area postrema and hypothalamus, reducing appetite through a pathway distinct from GLP-1. The combination with semaglutide targets two separate appetite-regulating systems simultaneously, producing additive weight loss beyond either agent alone.

Common Uses
  • Type 1 diabetes (adjunct to insulin)
  • Type 2 diabetes (adjunct to insulin)
  • Postprandial glucose control
  • Modest weight loss
  • Weight management (investigational)
  • Type 2 diabetes (investigational)
  • Metabolic syndrome
Known Risks
  • Severe hypoglycemia (especially in type 1 diabetes — boxed warning)
  • Nausea (common, usually transient)
  • Headache
  • Anorexia
  • Requires careful insulin dose adjustment
  • GI side effects (nausea, vomiting) — similar to GLP-1 class
  • Still in Phase 3 trials — full safety profile not established
  • Injection site reactions
  • Long-term effects unknown
Regulatory Status
FDA Approved

FDA-approved as Symlin (2005) for type 1 and type 2 diabetes as an adjunct to mealtime insulin. Requires insulin dose reduction to prevent hypoglycemia. Pen injector for self-administration.

Investigational

Currently in Phase 3 trials as CagriSema (cagrilintide 2.4 mg + semaglutide 2.4 mg). Phase 3 REDEFINE 1 trial showed ~22.7% weight loss at 68 weeks. Potential FDA submission 2026-2027. Represents the next generation beyond tirzepatide in the weight management pipeline.
