Could a diabetes drug ease long COVID fatigue?
NCT ID NCT07128082
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether tirzepatide (Zepbound), a drug used for diabetes and weight loss, can reduce Long COVID symptoms like fatigue. About 1000 adults with Long COVID will take either the drug or a placebo for 12 months, and all tasks are done remotely. The main goal is to see if fatigue scores improve compared to placebo.
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 it works, this could point toward a treatment that reduces fatigue and improves quality of life for people with Long COVID.
- What could go wrong
- This is a Phase 2 trial, so it is still early. The medication may not work better than a placebo, and side effects from tirzepatide (like nausea or digestive issues) are possible.
