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.
Cagrilintide was selected through a published medicinal chemistry program and is supported by preclinical amylin-receptor biology.
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.
Most adverse events are gastrointestinal or injection-site related. No approved-product post-marketing dataset exists.

Long-acting acylated human amylin analogue
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
- 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.
- 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.
- 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.
- 2026Human study
RENEW Phase 3 underway
ClinicalTrials.gov records and Novo materials show dedicated Phase 3 cagrilintide monotherapy development.
Key clinical trials
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.
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.
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.
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.
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.
Is standalone cagrilintide FDA-approved?
No. There is no approved cagrilintide monotherapy product. It remains investigational.
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.
Legal & regulatory status
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]
