Dose-ranging Study of Rifaximin Soluble Solid Dispersion (SSD) Tablets for the Prevention of Complications of Early Decompensated Liver Cirrhosis

Summary

The primary objective of this study is to assess the efficacy of rifaximin SSD versus placebo in preventing complications of liver cirrhosis, such as all-cause mortality (death due to all causes) or hospitalization, in subjects with early decompensated liver cirrhosis. Rifaximin, a non-systemic antibacterial agent, is currently marketed as a 550 mg tablet for the reduction in risk of recurrent overt hepatic encephalopathy, a complication of liver cirrhosis. The rifaximin SSD tablet was formulated to maximize the efficacy of rifaximin. Subjects will receive 1 of 5 doses of rifaximin SSD tablets or placebo tablets every day for 24 weeks.
