What Cagrilintide is
Cagrilintide is an investigational long-acting, lipidated analogue of the pancreatic hormone amylin that acts at amylin and calcitonin receptors and is given by once-weekly subcutaneous injection in clinical trials. It has been studied alone in a phase 2 weight-management trial and, most extensively, in combination with semaglutide (CagriSema) in phase 3 trials, with gastrointestinal events the most commonly reported adverse events. It is not approved by the FDA, and this entry summarizes published and registered trials for research reference only.
Natural amylin is a pancreatic hormone co-secreted with insulin that induces satiety; cagrilintide is a stable, lipidated, long-acting amylin analogue 1,7. Receptor pharmacology Cryo-electron microscopy structures show cagrilintide bound to Gs-coupled amylin receptors (AMY1R, AMY2R, AMY3R) and the calcitonin receptor, with an amylin-like binding mode but distinct conformational dynamics compared with other… How it works →
Key evidence
- Lau et al., Lancet (phase 2, monotherapy) · 2021 · Humans (adults with overweight or obesity without diabetes)Mean weight reduction was 6.0% to 10.8% across cagrilintide doses versus 3.0% with placebo; the highest dose exceeded liraglutide 3.0 mg (10.8% vs 9.0%); gastrointestinal adverse events occurred in 41% to 63% versus 32% with placebo 1. 1

Supplies and handling
- Lyophilized vialSealed vial with the freeze-dried cake. Check the label, lot and the certificate of analysis before opening.
- Sterile diluentThe diluent named on the product documentation. Bacteriostatic water contains benzyl alcohol; sterile water does not.
- Graduated syringesSized to the volume being measured. U-100 insulin syringes are graduated in units where 100 units = 1 mL.
- Alcohol prep padsFor wiping vial stoppers before each puncture.
- Nitrile glovesClean gloves for aseptic handling.
- Sharps containerPuncture-resistant container for used needles.
Storage
No approved-product storage instructions exist because cagrilintide has no FDA label. Handling of research material should follow the supplier's documentation and certificate of analysis, including temperature, light protection and freeze-thaw limits.
- Lyophilized (unmixed) vials: typically stored cold and dry, away from light, as the documentation directs. Many are stable longer frozen.
- Reconstituted vials: typically refrigerated (about 2–8 °C), protected from light and not frozen.
- Bacteriostatic water contains benzyl alcohol, which inhibits bacterial growth in multi-use vials; sterile water has no preservative.
Handling mistakes and troubleshooting
- Added the wrong volume of diluent
- The concentration changes, not the amount of compound in the vial. Recalculate with the volume actually added and relabel the vial.
- Shook the vial and it foamed
- Let it settle in the refrigerator. Foam is a sign of agitation; some peptides aggregate when shaken. Note it on the label.
- The solution is cloudy or has particles
- Do not use it. Cloudiness can indicate incomplete dissolution, contamination or degradation. Record the lot and contact the supplier with the certificate of analysis.
- The powder cake looks melted or shrunken before reconstitution
- This can indicate the vial was exposed to heat or moisture. Record the lot and condition on arrival.
- Liquid sprayed back when the needle was removed
- Pressure built up in the vial. Withdraw a small volume of air while adding diluent to keep pressure neutral.
