Key differences

  • Evidence level differs: Cagrilintide is investigational (in trials), while Exenatide is fda-approved.
  • Dosing units differ: Cagrilintide is dosed in mg, Exenatide in mcg — they operate at different scales.
  • Frequency: Cagrilintide is typically once weekly subcutaneous; Exenatide is Twice daily (immediate-release) or once weekly (extended-release).

How each works

Cagrilintide

Cagrilintide activates amylin receptors (RAMP/CTR complexes) in the area postrema and hypothalamus, reducing food intake and slowing gastric emptying through mechanisms independent of GLP-1 signaling. This non-overlapping pathway allows combination with semaglutide without compounding GI side effects. Phase 2 CagriSema data showed 15–25% weight loss at 32 weeks, supporting the complementary mechanism hypothesis.

Exenatide

Exenatide was identified from Gila monster (Heloderma suspectum) venom as exendin-4, a peptide with ~53% homology to human GLP-1 but with DPP-4 resistance enabling longer activity. Clinical trials demonstrated HbA1c reductions of 0.8–1.0%, weight loss of 2–4kg, and cardiovascular safety (EXSCEL trial showed non-inferiority). The extended-release microsphere formulation achieved comparable efficacy with once-weekly dosing.
