Cagrilintide

Cagrilintide (AM833 / NNC0174)

An investigational long-acting amylin analogue from Novo Nordisk. It is the amylin component of CagriSema and is now in a dedicated Phase 3 monotherapy program.

At a glance

Cagrilintide is a long-acting amylin analogue from Novo Nordisk. It is not a GLP-1 drug. It matters because amylin has become one of the main "beyond GLP-1" obesity mechanisms, both as a standalone pathway and as the amylin half of CagriSema.

Animal studiesStrongExtensive preclinical

Cagrilintide was selected through a published medicinal chemistry program and is supported by preclinical amylin-receptor biology.

Human evidenceModerate800+ direct subjects

Standalone cagrilintide has Phase 2 dose-finding data and a Phase 3 REDEFINE 1 monotherapy arm. Dedicated RENEW Phase 3 monotherapy outcomes are not yet available.

Safety dataModeratePhase 1-3 exposure

Most adverse events are gastrointestinal or injection-site related. No approved-product post-marketing dataset exists.

What is cagrilintide?

Cagrilintide is an investigational analogue of amylin, a hormone co-secreted with insulin by pancreatic beta cells. Natural amylin helps regulate satiety and post-meal glucagon, but it is hard to turn into a convenient drug because native amylin can aggregate and has a short useful exposure window.[2]

Novo Nordisk engineered cagrilintide to be more stable and long-acting. In practical terms, the program asks whether amylin can become for obesity what GLP-1 became over the last decade: a druggable gut-pancreas-brain signal that changes food intake in a clinically meaningful way.

Cagrilintide is also the amylin component of CagriSema. That combination evidence is important, but this profile focuses on cagrilintide itself: what the standalone data show, what the combination data imply, and what remains unknown.


How it works

Cagrilintide activates amylin-family receptors involved in satiety signaling. The clinical goal is not to mimic GLP-1; it is to add a different appetite-regulation pathway.

Mechanism details

Amylin is part of the calcitonin peptide family. Functional amylin receptors are formed from calcitonin receptors plus receptor activity-modifying proteins. Cagrilintide is designed to activate this receptor family while avoiding the aggregation problems that limit native amylin as a drug candidate.[2]

In obesity pharmacology, the key effects are:

  • Increased satiety and reduced food intake.
  • Slower gastric emptying and altered post-meal signaling.
  • Suppression of inappropriate glucagon secretion.
  • Complementarity with GLP-1 receptor agonism, as seen in CagriSema.

What the research says

Cagrilintide is no longer just a supporting actor for semaglutide. The dedicated RENEW program means amylin monotherapy is now a serious clinical development path.

Research timeline

  1. 2021Human study

    Medicinal chemistry and Phase 2 dose-finding published

    Novo's development paper described the long-acting amylin analogue design; a Lancet Phase 2 trial showed dose-dependent weight loss.

  2. 2023Human study

    CagriSema Phase 2 diabetes data

    Cagrilintide was tested alone and with semaglutide in type 2 diabetes, supporting the additive amylin + GLP-1 rationale.

  3. 2025Human study

    REDEFINE 1 monotherapy signal

    Cagrilintide 2.4 mg monotherapy showed 11.8% weight loss versus 2.3% placebo at 68 weeks under the trial-product estimand.

  4. 2026Human study

    RENEW Phase 3 underway

    ClinicalTrials.gov records and Novo materials show dedicated Phase 3 cagrilintide monotherapy development.

Key clinical trials

2021·Multicenter, randomized, double-blind, placebo- and active-controlled·n=706High quality

Phase 2 dose-finding — once-weekly cagrilintide

Overweight or obesity without diabetes

Cagrilintide produced dose-dependent weight loss from 6.0% to 10.8% at 26 weeks versus 3.0% with placebo.

2023·Multicenter, randomized, double-blind, active-controlled·n=92Moderate quality

Phase 2 type 2 diabetes — cagrilintide with and without semaglutide

Type 2 diabetes with overweight or obesity

Cagrilintide monotherapy produced weight loss but weaker glycemic effects than the CagriSema combination, clarifying its role as the amylin component.

2025·Phase 3a monotherapy arm within CagriSema obesity trial·n=302Moderate quality

REDEFINE 1 monotherapy arm

Obesity or overweight without diabetes

Novo reported 11.8% mean body-weight reduction with cagrilintide 2.4 mg versus 2.3% with placebo at 68 weeks under the trial-product estimand.


What the evidence shows

Does cagrilintide cause weight loss by itself?

Yes, but pivotal standalone confirmation is still pending. Phase 2 showed dose-dependent weight loss up to 10.8% at 26 weeks, and the REDEFINE 1 monotherapy arm reported 11.8% at 68 weeks.

Well-supported

Is cagrilintide a GLP-1 drug?

No. Cagrilintide is an amylin analogue. Its relevance is that amylin can complement GLP-1 therapy rather than duplicate it.

Not yet demonstrated

Is amylin one of the main beyond-GLP-1 mechanisms?

Partially supported. Cagrilintide has standalone human data, combination Phase 3 evidence through CagriSema, and a dedicated Phase 3 monotherapy program. That makes amylin one of the most credible next mechanisms, though not the only one.

Some supporting evidence

Is standalone cagrilintide FDA-approved?

No. There is no approved cagrilintide monotherapy product. It remains investigational.

Not yet demonstrated

Safety & side effects

The published Phase 2 trial reported gastrointestinal adverse events as the most frequent category, especially nausea, constipation, and diarrhea. Injection-site reactions also appeared. This is directionally consistent with amylin biology and with the broader incretin/amylin development landscape.[1]

Safety gaps to keep clear:

  • No approved-product label.
  • No post-marketing surveillance.
  • Limited long-term standalone exposure.
  • Uncertain comparative tolerability versus semaglutide, tirzepatide, or CagriSema.

Cagrilintide is promising because it is different from GLP-1, not because it is side-effect free. The RENEW Phase 3 program is the key dataset to watch for standalone tolerability.


Cagrilintide is not FDA-approved as a standalone medicine. It is part of CagriSema, which has an FDA NDA filed, but that does not make cagrilintide itself an approved monotherapy.[5]

For athletes, cagrilintide should be treated as prohibited under WADA S0 because it is an unapproved pharmacological substance.[8]
