RED-C-3132 Trial Summary

This trial will test whether rifaximin can help delay the first episode of overt hepatic encephalopathy (OHE) in people with advanced liver cirrhosis.

Participants must have a clear mental state (MMSE score >24) and no severe brain dysfunction (Conn score <2). Those with recent serious infections, internal bleeding, kidney issues, or past overt hepatic encephalopathy are excluded.Check my eligibility
What is being tested?
The study compares Rifaximin SSD-40mg IR against a placebo to see if it can delay the first episode of overt hepatic encephalopathy—a severe liver-related brain disorder—in patients with liver cirrhosis. It's randomized and double-blind, meaning neither doctors nor patients know who gets the real treatment.See study design
What are the potential side effects?
Potential side effects of Rifaximin may include abdominal pain, nausea, dizziness, fatigue, peripheral edema (swelling), anemia (low red blood cell count), rash or itching. The exact side effects will be monitored throughout the trial.
