Could a 14-Day pill reverse stomach precancer?
NCT ID NCT06590454
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether the drug pyrvinium can reverse gastric intestinal metaplasia, a condition that raises the risk of stomach cancer. Thirty-two adults with high-risk features will take pyrvinium or a placebo for 14 days. Researchers will compare biopsies before and after treatment to see if the precancerous changes improve.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pyrvinium
- What this could lead to
- If it works, this could point toward a drug treatment to reverse precancerous changes in the stomach and lower the risk of stomach cancer.
- What could go wrong
- This is a small early-phase trial with only 32 people. The drug may not reverse the precancerous changes, and side effects are possible. Success in the lab may not translate to real-world benefit.
