NCT01196507

  Purpose

Patients of cirrhosis with portal hypertension aged 18 to 75 years who have small esophageal varices with or without red color signs and have not bled previously will be enrolled. After baseline evaluation, the participants will be randomized to receive either Placebo or Carvedilol 6.25 mg BD. After randomization they will be followed up for one year. The primary endpoint of the study is the the proportions of patients who develop large varices (Gd 3 or Gd 4) at 1 year in each group. The secondary endpoint is the development of complications of cirrhosis (ascites, hepatic encephalopathy, SBP), mortality, and adverse effects of drugs

Primary Outcome Measures:
  • The primary endpoint of the study is the the proportions of patients who develop large varices (Gd 3 or Gd 4) during the period of 1.5 year in each group. [ Time Frame: 2 Years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Survival [ Time Frame: 2 Years ] [ Designated as safety issue: No ]
  • adverse effects of drugs [ Time Frame: 2 Years ] [ Designated as safety issue: Yes ]
  • reduction in HVPG [ Time Frame: 1 Year ] [ Designated as safety issue: No ]
  • Change in liver severity score such as CTP (Child-Turcotte-Pugh) and MELD (Model for End stage Liver Disease) [ Time Frame: 2 Years ] [ Designated as safety issue: No ]

Enrollment: 140
Study Start Date: November 2010
Study Completion Date: April 2014
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Carvedilol
Tablet Carvedilol 6.25 mg BD
Drug: Carvedilol
Carvedilol will be administered orally at a start dose of 3.125 mg twice daily. After 1 week, this will increased if systolic blood pressure does not fall below 90 mm Hg. The patient will receive the maximum tolerated dose of carvedilol with a maximum of 6.25 BD.
Placebo Comparator: Placebo
Placebo tablets 2 BD
Drug: Placebo
The placebo tablets will be identical to the carvedilol tablets. First the patients will receive placebo in the dose of 1 BD. Then depending on his tolerance it will be increased to a maximum of 2 BD.
