Official title

The Role of Bacterial Overgrowth and Delayed Intestinal Transit in Hepatic Encephalopathy. Phase A: Breath Testing and Colonic Transit in Hepatic Encephalopathy. Phase B: A Randomized Double Blind, Placebo Controlled Trial of Rifaximin for Hepatic Encephalopathy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study will be conducted in two phases. Phase A will evaluate the contribution of bacterial overgrowth and colonic inertia to development of Hepatic Encephalopathy (HE)in 50 ambulatory subjects with HE and hepatitis C cirrhosis. This phase will include a Screening and Evaluation Visit. Phase B will evaluate the effect of rifaximin on bacterial outgrowth and severity of HE in 20 of the subjects enrolled in Phase A who have a somewhat greater degree of encephalopathy. The purpose of this study is to evaluate the following: 1. the relationship between bacterial overgrowth and the presence and severity of HE in patients with hepatitis C cirrhosis; 2. the effectiveness and tolerability of rifaximin relative to placebo in treatment of HE associated with hepatitis C cirrhosis; 3. the relationship between bacterial overgrowth and the presence and severity of HE before and after rifaximin treatment.
