Weight-Loss combo CagriSema tested for drug interactions
NCT ID NCT06289504
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 1 study in 34 adults with overweight or obesity examined whether CagriSema (a combination of cagrilintide and semaglutide) changes how the body processes atorvastatin (a cholesterol drug) and warfarin (a blood thinner). Participants took single doses of atorvastatin and warfarin before and after reaching steady-state levels of CagriSema. The goal was to measure drug levels in the blood and the effect of warfarin, helping guide safe co-prescribing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CagriSema (cagrilintide and semaglutide combination)
- What this could lead to
- If successful, this study could help doctors understand how to safely prescribe common medications like atorvastatin and warfarin alongside CagriSema for weight management.
- What could go wrong
- This is a small, early-stage drug interaction study, not a test of weight loss or safety. Results may not apply to broader populations or predict real-world outcomes.
