CagriSema combination used 2.4 mg cagrilintide + 2.4 mg semaglutide. Showed ~25% weight loss.

Injection Sites

Abdomen (trial protocol)

Subcutaneous injection, same sites as other GLP-1 agents.

  • Rotate sites
  • In CagriSema trials, cagrilintide and semaglutide were given as separate injections

Storage Instructions

  • Investigational product
  • If compounded: follow compounding pharmacy instructions
  • Requires refrigeration (2°C–8°C) typically

Common Side Effects

Contact your healthcare provider if side effects are severe or persistent.

  • Nausea
  • Vomiting
  • Injection site reactions
  • Decreased appetite
  • When combined with semaglutide: amplified GI side effects

Frequently Asked Questions

Q

What is cagrilintide?

Cagrilintide is a long-acting amylin analogue. Amylin is a hormone co-secreted with insulin that suppresses appetite and slows gastric emptying. Cagrilintide extends this effect with a once-weekly injection. Novo Nordisk is studying it primarily in combination with semaglutide.
Q

What is CagriSema?

CagriSema is the co-formulation of cagrilintide and semaglutide being developed by Novo Nordisk. Phase 3 trials (REDEFINE program) are ongoing. It achieved ~25% average weight loss in Phase 2, which would be competitive with retatrutide and tirzepatide.
Q

Is cagrilintide available as a compounded peptide?

Some peptide research vendors offer cagrilintide, but it is not FDA-approved and its safety and quality outside clinical trials is unverified. Consult a physician before considering any experimental compound.
