RPPCLC: Rifaximin for Preventing Progression and Complications in Patients With Decompensated Liver Cirrhosis
Study Details
Study Description
Brief Summary
It is still not clear whether rifaximin can prevent the progression of liver cirrhosis, reduce the overall complications and improve the survival in patients with decompensated cirrhosis. This is a multi-center open-labelled randomized prospective study to evaluate the efficacy and safety of rifaximin in preventing the progression and complications in cirrhotic patients, and explore its reasonable dosage and possible mechanism. A total of 150 patients with decompensated liver cirrhosis will be enrolled in the study and randomly divided into three groups (the control group (A), the low-dose rifaximin treatment group (B), and conventional dose rifaximin treatment group (C)) with a ratio of 1:2:2. The patients in group B are given rifaximin with the dose of 600mg/d (600mg, qd) for 24 weeks, and the patients in group C are delivered 1200mg/d (600mg, bid) of rifaximin .During the entire study period, all other therapeutic strategies are kept unchanged in all the groups as long as possible. The proportion of patients with progression of cirrhosis, the incidence of total complications and each complication, survival rate and time, liver function and adverse events will be compared among the three groups. This study might provide a new feasible method with clinical application prospects for preventing the progression and reducing the incidence of liver cirrhosis related complications, improve the prognosis of patients with decompensated liver cirrhosis, and save medical resources.

Detailed Description
Rifaximin has been recommended as a prophylactic drug for hepatic encephalopathy (HE) and spontaneous bacterial peritonitis (SBP), the two major complications of liver cirrhosis. However, it is still not clear whether rifaximin can prevent the progression of liver cirrhosis, reduce the overall complications and improve the survival in patients with decompensated cirrhosis. Additionally, the role of rifaximin in the treatment of liver cirrhosis has not been fully clarified. We designed a multi-center open-labelled randomized prospective study to evaluate the efficacy and safety of rifaximin in preventing the progression and complications in cirrhotic patients, and explore its reasonable dosage and possible mechanism. A total of 150 patients with decompensated liver cirrhosis will be enrolled in the study. They will be randomly divided into three groups (the control group (A), the low-dose rifaximin treatment group (B), and conventional dose rifaximin treatment group (C)) with a ratio of 1:2:2. The patients in group B are given rifaximin with the dose of 600mg/d (600mg, qd) for 24 weeks, and the patients in group C are delivered 1200mg/d (600mg, bid) of rifaximin .During the entire study period, all other therapeutic strategies, such as antiviral agents, non-selective beta-blockers, liver protectants, and diuretics, are kept unchanged in all the groups as long as possible. The proportion of patients with progression of cirrhosis, acute decompensation, acute-on-chronic liver failure (ACLF), decompensation and stable decompensated cirrhosis, the incidence of total complications and each complication, survival rate and time, liver function and adverse events will be compared among the three groups. This study might provide a new feasible method with clinical application prospects for preventing the progression and reducing the incidence of liver cirrhosis related complications, improve the prognosis of patients with decompensated liver cirrhosis, and save medical resources.

The incidence of overall complications resulting from decompensated liver cirrhosis in 12weeks and 24weeks, including refractory ascites, SBP, esophageal and gastric variceal bleeding (EGVB), overt hepatic encephalopathy(OHE), cute renal injury (AKI)/hepatorenal syndrome (HRS), primary hepatic carcinoma (PHC), etc.
- Incidence of various complications of liver cirrhosis, including: refractory ascites, SBP, EGVB, OHE, AKI/HRS, PHC, etc. [12 weeks and 24 weeks]
The incidence of each complication resulting from decompensated liver cirrhosis in 12weeks and 24weeks, including refractory ascites, SBP, EGVB, OHE, AKI/HRS, PHC, etc.

The proportion of patients with acute decompensated (AD)
- The proportion of patients with stable decompensated cirrhosis [24 weeks]
The proportion of patients with stable decompensated cirrhosis, which is defined as patients with decompensated cirrhosis who, while receiving sustained prophylaxis with diuretics, and/or lactulose or rifaximin, and/or non-selective beta-blockers or repeated endoscopic treatment of esophagogastric varices, do not present episodes of AD for a long-time period.
