Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will look at the safety of a drug used in participants who have had hepatic encephalopathy (HE) in the past.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eligible participants had a history of HE, a Conn score of 0 to 2 at enrollment, and either had successfully participated in a previous HE study with rifaximin (that is, RFHE3001 \[NCT00298038\]), or were new participants enrolled with ≥1 verifiable episode of HE (equivalent to a Conn score of ≥2) associated with cirrhosis or portal hypertension within 12 months of screening.

Successful participation in a previous rifaximin study was defined as having received ≥80% and ≤120% of the expected tablets, having been reasonably compliant with study procedures, and having not been discontinued from the previous study due to study drug-related Adverse Events. Participants who experienced HE or associated symptoms during or after the RFHE3001 study were considered eligible for entry into this open-label study if the participant and Investigator did not perceive study medication as a possible cause of the HE episode or associated symptoms. Participants who did not participate in a previous HE study with rifaximin were eligible if this open-label study was the only rifaximin HE study available at an individual site.

Rifaximin

Participants from a previous rifaximin HE study and new participants were administered a single rifaximin 550 milligram (mg) tablet 2 times per day (approximately every 12 hours) for at least 24 months, until regulatory approval of rifaximin for reduction in risk of overt HE recurrence, or until the sponsor closed the study.
