What is Cagrilintide?

Cagrilintide is a long-acting acylated amylin analogue engineered for extended receptor engagement at the amylin receptor complex (AMY1 and AMY3). Its mechanism involves activating calcitonin and amylin receptors in the area postrema and hypothalamus, modulating satiety signaling and gastric emptying. In the REDEFINE 1 phase 3 trial (Lau et al., published 2023), cagrilintide 2.4 mg administered weekly demonstrated statistically significant weight reduction compared to placebo over 68 weeks. Notably, Novo Nordisk's CagriSema program combines cagrilintide with semaglutide, and phase 2 data (REDEFINE 2) showed the combination achieved greater weight reduction than either agent alone, suggesting synergistic effects between amylin and GLP-1 receptor pathways. Compared to pramlintide, the only previously available amylin analogue, cagrilintide offers a substantially longer half-life (approximately 7 days vs. hours), enabling once-weekly dosing in research protocols. Research also indicates potential benefits in alcohol-related liver disease models, where amylin signaling may reduce hepatic lipid accumulation. The lyophilized powder should be stored at -20C prior to reconstitution with sterile water or bacteriostatic water; reconstituted solutions should be refrigerated at 2-8C. This compound is primarily studied by obesity research institutes, pharmaceutical laboratories investigating incretin-amylin synergy, and academic centers focused on appetite neurobiology and hepatic metabolism.

Cagrilintide Research Applications

In published and preclinical research, Cagrilintide has been studied across the following areas:

Obesity and type 2 diabetes management studies
Synergistic weight loss research with semaglutide
Liver injury and alcohol-related liver disease research
Cardiovascular condition exploration

Cagrilintide in Research: Reconstitution & Study Concentrations

Cagrilintide is a long-acting amylin analog studied alone and in combination with semaglutide (CagriSema) in published clinical research. In the laboratory the lyophilized peptide is reconstituted with bacteriostatic water; working concentration depends on the assay. Cagrilintide is not FDA-approved and is supplied for research use only.

Worked example: a 10mg vial reconstituted with 2 mL of bacteriostatic water yields 5.00 mg/mL.

Cagrilintide — Frequently Asked Questions

What is Cagrilintide and how does it work?

Cagrilintide is a long-acting synthetic analogue of amylin, a hormone co-secreted with insulin from pancreatic beta cells. It binds to amylin receptors (AMY1 and AMY3), which in preclinical models has been observed to influence satiety signaling, gastric emptying rate, and post-meal glucagon secretion. Its acylated fatty acid modification extends its half-life, enabling less frequent dosing in research protocols.

What research has been done on Cagrilintide?

Novo Nordisk's Phase 2 trials (published 2021-2023) studied cagrilintide both as a monotherapy and in combination with semaglutide (the CagriSema program). Research data showed statistically significant reductions in body weight compared to placebo. Preclinical studies have also investigated its effects on alcohol-related liver disease models and cardiovascular biomarkers in animal subjects.

How does Cagrilintide compare to Pramlintide?

Pramlintide (Symlin) is the only currently approved amylin analogue but requires multiple daily administrations due to its short half-life. Cagrilintide's acylation modification provides a substantially longer duration of action, enabling once-weekly dosing in research protocols. In comparative studies, cagrilintide demonstrated stronger receptor binding affinity at AMY1 and AMY3 receptors than native amylin or pramlintide.

What is the recommended reconstitution protocol for Cagrilintide?

For this 10mg vial, reconstitute with 1mL of bacteriostatic water to yield a concentration of 10.0mg/mL. Inject the water slowly along the inner wall of the vial — do not shake or agitate. Allow the lyophilized powder to dissolve fully (typically 2-5 minutes). Store reconstituted solution at 2-8°C and use within 30 days.

Is Cagrilintide legal to buy for research?

Cagrilintide is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.

How is Cagrilintide reconstituted for research use?

Cagrilintide ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.

Does Cagrilintide come with a Certificate of Analysis?

Yes. Every batch of Cagrilintide from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
