Mechanism of Action
How Cagrilintide Works
Cagrilintide is a long-acting analog of amylin, a pancreatic hormone co-secreted with insulin that produces satiety. It activates amylin receptors (AMY1-3) in the area postrema and nucleus tractus solitarius to slow gastric emptying, reduce glucagon secretion, and suppress appetite centrally. When combined with semaglutide (CagriSema), the complementary amylin + GLP-1 mechanisms produce additive weight loss approaching bariatric surgery outcomes.
- Activates AMY1, AMY2, AMY3 receptor subtypes
- Area postrema and NTS satiety center activation
- Reduces meal size and total caloric intake dose-dependently
- Semaglutide component activates hypothalamic GLP-1R
- Dual mechanism produces 20.4% adipose reduction (vs. 3% placebo)
- 60% of CagriSema study observations achieved >=20% adipose reduction
- Suppresses postprandial glucagon secretion
- Slows gastric emptying rate
- 88% of prediabetic research cohorts returned to normoglycemia (REDEFINE 1)
Cagrilintide binds calcitonin and amylin receptors (CTR+RAMP1/2/3) in the brainstem area postrema, activating ascending satiety signals that reduce meal size and caloric intake. It slows gastric emptying and suppresses postprandial glucagon secretion. Its long acyl chain enables once-weekly dosing with sustained receptor occupancy. Phase 2 showed cagrilintide 4.5mg surpassed liraglutide 3.0mg (10.8% vs. 9.0%, P=0.03).

Clinical Data
REDEFINE 1: 20.4% Adipose Reduction at 68 Weeks — NEJM 2025
The REDEFINE 1 Phase 3a trial (N Engl J Med, 2025) demonstrated CagriSema (cagrilintide 2.4mg + semaglutide 2.4mg) achieved -20.4% mean adipose reduction vs. -3.0% placebo at 68 weeks (P<0.001). 60% of study observations achieved >=20% adipose reduction, 23% achieved >=30%. As monotherapy (separate Phase 2), cagrilintide 4.5mg produced 10.8% adipose reduction vs. 3.0% placebo, surpassing liraglutide 3.0mg (P=0.03). In REDEFINE 2 (T2D), CagriSema achieved -13.7% vs. -3.4% placebo.

Research Safety Notes
- Safety profile consistent with GLP-1 receptor agonist class — primarily GI adverse events
- Nausea is the most common AE (~55% CagriSema), generally transient and mild-to-moderate
- Low treatment discontinuation rates (6–8.4%) across REDEFINE Phase 3 trials
- No unexpected cardiovascular signals observed in Phase 3 program
- Long-term safety beyond 68 weeks under continued evaluation
Cagrilintide and CagriSema are investigational. REDEFINE Phase 3 data published in NEJM (2025). Not yet FDA-approved. For research use only.
