Can a parasite drug help fight a deadly gut infection in cirrhosis?
NCT ID NCT07808450
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
This trial tests whether adding nitazoxanide, a drug used for parasitic infections, to standard antibiotics can improve outcomes for people with liver cirrhosis who develop spontaneous bacterial peritonitis, a severe infection of the abdominal fluid. Researchers will compare two groups: one receiving standard care plus a placebo, and another receiving standard care plus nitazoxanide for 14 days. The main goal is to see if nitazoxanide reduces the number of infection-fighting cells in the abdominal fluid within 48 hours, which would indicate a faster response to treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Nitazoxanide, an antiparasitic drug with anti-inflammatory effects, added to standard antibiotics
- What this could lead to
- If it works, adding nitazoxanide to standard antibiotics could reduce the severity of spontaneous bacterial peritonitis and lower the risk of recurrence in people with cirrhosis.
- What could go wrong
- This is an early-phase trial with only 60 participants, so results may not apply broadly. Nitazoxanide may not provide added benefit over standard care, and its safety in this setting is not yet established.
