Weight-Loss drug tirzepatide takes on heart flutter in new trial
NCT ID NCT06802081
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 study at the Cleveland Clinic will test whether the weight-loss drug tirzepatide (Zepbound) can help people with obesity and atrial fibrillation (AFib). About 100 participants will receive weekly injections of tirzepatide or a placebo for up to 12 months. The main goal is to see if weight loss reduces the total time spent in AFib and improves symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tirzepatide (Zepbound)
- What this could lead to
- If successful, this could show that weight loss with tirzepatide helps control atrial fibrillation symptoms and reduce time spent in AFib.
- What could go wrong
- This is a small, early-phase trial (100 people) at one center. Results may not apply to everyone, and tirzepatide has side effects like nausea and vomiting. The study is not designed to prove long-term safety or efficacy.
