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 (11.8% weight loss vs. 2.3% placebo at 68 weeks, trial-product estimand). A dedicated Phase 3 monotherapy programme is running, but no pivotal standalone results have been reported.
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. Two dedicated Phase 3 monotherapy trials are running, and Novo has guided to starting a further high-dose Phase 3 in late 2026 — amylin on its own is now a serious clinical development path. What does not yet exist is a single standalone Phase 3 result.
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
Dedicated Phase 3 monotherapy underway
Two Phase 3 cagrilintide monotherapy trials started in November 2025 — NCT07220642 in overweight/obesity (300 participants) and NCT07220759 in overweight/obesity with type 2 diabetes (330 participants) — and both are now closed to recruitment. Novo's August 2026 investor materials add a high-dose Phase 3 initiation guided for Q4 2026, plus a registered Phase 3 comparing two injectable formulations. No standalone Phase 3 results have been reported.
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 dedicated Phase 3 monotherapy trials are 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 is under FDA review — Novo told investors in August 2026 that it expects a US decision in the fourth quarter of 2026, its own guidance rather than a published FDA action date. Even if CagriSema is approved, that would not make cagrilintide an approved monotherapy: the two are separate regulatory questions, and the standalone Phase 3 trials have not reported.[5][9]
A note on the programme name. Novo's 2025 annual report refers to the dedicated cagrilintide monotherapy programme as RENEW. That name does not appear in the ClinicalTrials.gov records for these trials, so this page identifies them by registry number instead — NCT07220642 in overweight and obesity, and NCT07220759 in overweight and obesity with type 2 diabetes.[6][7]
For athletes, cagrilintide should be treated as prohibited under WADA S0 because it is an unapproved pharmacological substance.[10]
