GLP-1 + Cagrilintide
Typical Dosing Protocols (Research/Compounded Use Only) Dosing Protocols (Research/Investigational)
+ Semaglutide (fixed-dose combination known as CagriSema) is Novo Nordisk’s once-weekly injectable dual agonist. It combines:
Semaglutide (2.4 mg) — a GLP-1 receptor agonist (the active ingredient in Wegovy and Ozempic) that reduces appetite, slows gastric emptying, and improves glycemic control.
Cagrilintide (2.4 mg) — a long-acting amylin receptor agonist (an analog of the pancreatic hormone amylin) that enhances satiety, further slows gastric emptying, and complements GLP-1 action.
The two mechanisms are synergistic: GLP-1 primarily curbs hunger and improves glucose regulation, while amylin adds stronger feelings of fullness and helps regulate post-meal glucose spikes.
Current Status (as of April 2026)
CagriSema is not yet FDA-approved in the United States (or most Western countries). Novo Nordisk submitted a New Drug Application for weight management in December 2025 based on the REDEFINE program, with an expected FDA decision in late 2026.
It is further along in development for both obesity and type 2 diabetes.
Key Efficacy Data from Phase 3 Trials
REDEFINE 1 (obesity/overweight without diabetes, 68 weeks):
Mean weight loss: 20.4% (up to 22.7% with full treatment adherence).
Superior to semaglutide 2.4 mg alone (14.9%) and cagrilintide alone (11.5%).
~40% of participants achieved ≥25% weight loss in some analyses.
REIMAGINE 2 (type 2 diabetes, 68 weeks):
Weight loss: 14.2% with CagriSema vs 10.2% with semaglutide 2.4 mg.
Superior HbA1c reduction: -1.91% vs -1.76% with semaglutide.
REDEFINE 4 (head-to-head vs tirzepatide 15 mg in obesity, 84 weeks):
CagriSema achieved 23% mean weight loss (full adherence) or 20.2% (treatment-regimen estimand).
Tirzepatide achieved 25.5% (full adherence) or 23.6% (treatment-regimen).
Did not meet the primary endpoint of non-inferiority to tirzepatide.
No clear weight-loss plateau was observed at the end of many trials, suggesting potential for further loss with longer treatment.
CagriSema consistently outperforms semaglutide alone (by ~5–8 percentage points in weight loss) and shows additive benefits from the amylin component.
Cardiometabolic and Other Benefits
Reductions in waist circumference, blood pressure, lipids, and liver fat.
Improved insulin sensitivity and glycemic control (especially relevant in type 2 diabetes).
High responder rates: Many participants achieve clinically meaningful thresholds (≥15%, ≥20%, or ≥25% weight loss).
