Cagrilintide
Long-Acting Amylin Analogue

Cagrilintide is a long-acting amylin analogue developed by Novo Nordisk as the amylin half of CagriSema — the combination of cagrilintide + semaglutide 2.4mg being studied as a next step beyond Wegovy. Amylin is a pancreatic hormone secreted with insulin that regulates post-meal satiety — a pathway entirely separate from GLP-1.

Overview

Amylin complements GLP-1 by acting on different brain regions and through different signaling pathways. GLP-1 reduces hunger primarily via the hypothalamus and brainstem; amylin acts on the area postrema and nucleus accumbens — affecting not just hunger but also the reward value of food and meal duration.

The combination produces what appears to be synergistic rather than merely additive weight loss — the SCALE NEXT trial of CagriSema showed 22.7% mean body weight reduction at 68 weeks, approaching tirzepatide's outcomes from a completely different mechanistic pairing.

"CagriSema is the first major combination to demonstrate that pairing GLP-1 with amylin — two separate satiety pathways — produces synergistic weight loss. It's a model for how different satiety mechanisms can be combined without redundancy."

Phase 3 REDEFINE trials are ongoing, positioning CagriSema as a potential successor to or combination partner for semaglutide in the obesity treatment pipeline.

Mechanism of Action

This compound operates through several converging biological pathways, which helps explain the breadth of effects observed across different tissue and metabolic models.

🔬

Amylin Receptor Agonism

Activates calcitonin receptor/RAMP complexes in the area postrema and nucleus accumbens — brain regions governing meal termination and food reward.

🧠

Area Postrema Satiety

Acts on the area postrema (outside the blood-brain barrier) to signal meal completion — a different CNS access point from GLP-1's hypothalamic action.

⏱️

Long-Acting Design

Fatty acid conjugation enables once-weekly dosing — matched to semaglutide's dosing interval for convenient combination research.

🎯

Complementary to GLP-1

Non-overlapping mechanism with GLP-1 agonists — each activates different receptors in different brain regions, producing additive or synergistic satiety effects.

Key Research Areas

Preclinical and clinical models have investigated this compound across a wide range of physiological contexts and tissue types.

  • Obesity weight loss — CagriSema Phase 2/3 showing ~22.7% body weight reduction
  • Amylin mechanism research — area postrema satiety signaling independent of GLP-1
  • Combination with semaglutide — dual satiety pathway activation studies
  • Food reward and eating behavior — nucleus accumbens amylin receptor role
  • Meal termination signals — post-meal satiety duration research
  • Type 2 diabetes — glycemic control via amylin's glucagon suppression
  • Next-generation obesity treatment research — beyond single-mechanism GLP-1

Cagrilintide's value in research is largely defined by its combination with semaglutide — demonstrating that non-overlapping satiety mechanisms can be combined for synergistic outcomes.

Compound Comparison

Cagrilintide, pramlintide, and semaglutide illustrate the evolution of amylin research — from short-acting standalone to long-acting combination that rivals surgical outcomes.

Safety Profile in Research Studies

The following reflects findings from published preclinical and clinical safety assessments where available.


Synergistic with GLP-1 — non-overlapping mechanism produces additive/synergistic weight loss in Phase 2/3


Once-weekly dosing — matched to semaglutide for convenient combination protocol


Phase 3 data incoming — REDEFINE program will provide definitive efficacy and safety data


Limited standalone data — primarily studied as part of CagriSema; standalone efficacy modest; dependent on combination context

Frequently Asked Questions
What is amylin and why does it matter for weight?
+
Amylin is a hormone co-secreted with insulin from pancreatic beta cells. It signals meal completion via the area postrema (outside the blood-brain barrier), slows gastric emptying, and suppresses glucagon. People with type 2 diabetes and obesity have impaired amylin secretion.
What is CagriSema?
+
CagriSema is the combination of cagrilintide 2.4mg + semaglutide 2.4mg, administered as separate once-weekly injections. The SCALE NEXT trial showed 22.7% mean body weight reduction at 68 weeks — approaching tirzepatide outcomes from a different mechanistic basis.
How does amylin differ from GLP-1 in the brain?
+
GLP-1 acts primarily on the hypothalamic arcuate nucleus to reduce hunger. Amylin acts on the area postrema and nucleus accumbens — affecting meal termination timing and the reward value of food rather than baseline hunger. They're complementary, not redundant.
When will Phase 3 data be available?
+
The REDEFINE Phase 3 program (5 trials) is ongoing as of 2026. Results from major readouts are expected 2026–2027. If successful, CagriSema could seek FDA approval shortly thereafter.
