Here’s an illustrative chart showing average weight-loss outcomes across different therapies—including CagriSema versus semaglutide (Wegovy) and tirzepatide. It highlights CagriSema’s impressive performance in clinical settings.
What Is CagriSema?
CagriSema is an experimental combination therapy being developed by Novo Nordisk that merges two distinct hormone analogs into a single once-weekly injection:
- Semaglutide – a GLP‑1 receptor agonist already approved for obesity and type 2 diabetes.
- Cagrilintide – a novel, long-acting amylin analog.
This fixed-dose combination, administered subcutaneously once weekly, is designed to enhance weight loss and blood sugar control through complementary effects on appetite, satiety, and metabolism.Drugs.comClarivate
Clinical Trial Results
Phase 2 (REIMAGINE) in Type 2 Diabetes
- Duration: 32 weeks
- Weight Loss: CagriSema achieved a mean reduction of 15.6%, compared to 5.1% with semaglutide alone and 8.1% with cagrilintide alone.PubMedAmerican College of Cardiology
- Blood Sugar (HbA₁c): CagriSema lowered HbA₁c by 2.2 percentage points, outperforming cagrilintide (−0.9) and trending slightly better than semaglutide (−1.8).PubMed
- Safety: Mostly mild to moderate GI adverse events; no severe hypoglycemia or fatal outcomes.PubMed
Phase 3 Trials (REDEFINE Program)
REDEFINE 1 (Overweight/Obese Adults Without Diabetes)
- Duration: 68 weeks
- Weight Loss:
- CagriSema: ~22.7%
- Semaglutide alone: ~16.1%
- Cagrilintide alone: ~11.8%
- Placebo: ~2.3%Drugs.comPatient Care OnlinePharmExecReutersFinancial Times
- Deep Responders: ~40% achieved ≥25% weight loss.Patient Care Online
- Side Effects: Predominantly transient, mild-to-moderate GI issues; ~6% discontinued due to adverse events (vs. 3.7% placebo).Drugs.comPharmExecReuters
REDEFINE 2 (Overweight/Obese Adults With Type 2 Diabetes)
- Duration: 68 weeks
- Weight Loss: ~15.7% vs. ~3.1% with placebo.Drugs.comThe TimesReutersGlobeNewswire
- Glycemic Control: Significant improvements in HbA₁c, with ~73.5% reaching ≤6.5%.Reuters
- Tolerability: Similar safety profile—mostly GI side effects; most were manageable.ReutersPharmExec
How It Works
- Dual Action Mechanism:
- Semaglutide enhances insulin secretion, suppresses appetite, and slows digestion.
- Cagrilintide mimics the hormone amylin, promoting fullness and slowing gastric emptying.
- Potential Advantage: Early preclinical data suggest CagriSema may also blunt the typical metabolic slow-down (adaptive thermogenesis) that occurs during weight loss, supporting more sustainable fat loss.PubMed

Summary Table
| Feature/Metric | CagriSema Highlights |
|---|---|
| Mechanism | Once-weekly combo of GLP‑1 RA (semaglutide) + amylin analog |
| Phase 2 (32 weeks) | ~15.6% weight loss; strong HbA₁c improvement |
| Phase 3 (REDEFINE 1) | ~22.7% weight loss; >40% achieved ≥25%; GI side effects mild-mod |
| Phase 3 (REDEFINE 2) | ~15.7% weight loss in diabetics; significant blood sugar benefits |
| Safety Profile | Similar to GLP‑1 drugs; mainly gastrointestinal, transient |
| Timeline | Potential approval around 2027 if trials and filings proceed |
| Competitive Edge | Could outperform semaglutide alone; still catching up to tirzepatide |
Final Thoughts
CagriSema represents a promising next-generation weight-loss medication, combining potent mechanisms to drive both appetite suppression and metabolic adaptation control. Its phase 3 results—while slightly below earlier expectations—demonstrate robust efficacy and tolerability, positioning it as a compelling alternative in obesity and diabetes management.
If you’d like, I can compare CagriSema further against alternatives like tirzepatide or semaglutide, explore availability timelines for Thailand, or discuss how side effects are managed.
