Use Cases Weight Loss Weight Loss
Key Effects
  • Dual Pathway Action: Combines amylin-mediated satiety and gastric emptying with GLP-1 appetite suppression and insulin secretion for additive weight loss.
  • Significant Weight Reduction: 20-23% body weight loss over 68-84 weeks in non-diabetic adults with obesity.
  • Glycemic Control: Lowers HbA1c by 1.5-2.2 percentage points in people with type 2 diabetes.
  • Dramatic Weight Loss: Up to 24% body weight reduction in trials.
  • Triple Action: Targets GLP-1, GIP, and glucagon receptors.
  • Metabolic Improvement: Better glucose control and metabolic health.
Dosage
  • Maintenance Dose: Cagrilintide 2.4 mg + semaglutide 2.4 mg, once weekly subcutaneous injection.
  • Titration Schedule: Starts at 0.25 mg/week, escalating through 0.5 mg, 1.0 mg, 1.7 mg over 16 weeks to reach maintenance 2.4 mg at week 17.
  • Clinical Trial Doses: 1-12mg weekly in phase 2 trials.
  • Weekly Injection: Administered once weekly.
Side Effects
  • GI Events: 79.6% of CagriSema users experienced gastrointestinal adverse events vs 39.9% on placebo.
  • Nausea: Most common side effect at 55%, usually mild-to-moderate and diminishing during titration.
  • Constipation and Vomiting: Reported in 30.7% and 26.1% of users respectively.
  • GI Effects: Nausea, vomiting, diarrhea common.
  • Similar to GLP-1s: Side effect profile comparable to semaglutide.
  • Dose-Related: Higher doses mean more side effects.

Community Sentiment

CAGRISEMA

62/100

Strong initial excitement after REDEFINE 1/2 results showing superior weight loss over semaglutide alone, but sentiment cooled after the February 2026 REDEFINE 4 trial failed to demonstrate noninferiority against tirzepatide (Zepbound). Still demonstrates clinically meaningful 23% weight loss and remains on track for potential FDA approval.

RETATRUTIDE

70/100

Early adopters report dramatic weight loss exceeding semaglutide results. Side effects similar to other GLP-1 agonists. Not yet FDA approved but generating significant interest.

Research Studies

CAGRISEMA (4 studies)

Coadministered Cagrilintide and Semaglutide in Adults with Overweight or Obesity

REDEFINE 1 phase 3a trial in 3,417 adults showed CagriSema achieved 22.7% mean weight loss at 68 weeks, superior to semaglutide alone (14.9%) and cagrilintide alone (11.5%). 60% of participants lost at least 20% of body weight.

NEJM
Cagrilintide-Semaglutide in Adults with Overweight or Obesity and Type 2 Diabetes

REDEFINE 2 trial in 1,206 adults with T2D across 12 countries. CagriSema achieved 15.7% weight loss and 73.5% of patients reached HbA1c of 6.5% or lower vs 15.9% on placebo.

PubMed
Efficacy and safety of co-administered once-weekly cagrilintide 2.4 mg with once-weekly semaglutide 2.4 mg in type 2 diabetes: a phase 2 trial

32-week trial in 92 participants with T2D. CagriSema achieved 15.6% weight loss vs 5.1% with semaglutide alone and 8.1% with cagrilintide alone. HbA1c reduction was 2.2 percentage points.
