Detailed Description:

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by participating institution, cirrhosis etiology, and hepatic venous pressure gradient.

The dose of oral timolol is titrated over 28 days. Patients are then randomly assigned to daily timolol at the titrated dose or a placebo if successful titration is achieved by day 28, and the final titration dose is maintained for at least 10 days. Timolol is discontinued prior to randomization.

Criteria for removal from study include esophageal or gastric varices, significant bleeding or hemorrhage, timolol-induced hepatic encephalopathy, and liver transplantation.

Patients are followed every 3 months.

  Eligibility

Ages Eligible for Study:   18 Years to 74 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria
  • Biopsy-proven cirrhosis of any etiology, including hepatitis B or C. No primary biliary cirrhosis.
  • Hepatic venous pressure gradient (HVPG) at least 6 mm Hg.
  • Histologic slides available for review OR liver-spleen scan compatible with cirrhosis if biopsy older than 5 years. Repeat biopsy required if scan incompatible OR HVPG at least 10 mm Hg and any of the following clinical features suggestive of cirrhosis: telangiectasias, palmar erythema, muscle wasting, liver hard and nodular, or splenomegaly, hypoalbuminemia, hyperbilirubinemia, or prolonged prothrombin time, liver-spleen scan with colloid shift to spleen or bone marrow, collaterals visualized by ultrasound or CT.
  • Gastroesophageal varices negative by endoscopy within 3 months prior to randomization.
  • Independent verification by 2 endoscopists required.
  • No ascites requiring specific treatment, e.g., diuretics, paracentesis, peritoneovenous shunt.
  • Ascites controlled by salt restriction alone allowed.
  • No splenic or portal vein thrombosis by Doppler-ultrasound.
  • No primary sclerosing cholangitis.
  • No radiologically or histologically proven hepatocellular carcinoma.

Prior/Concurrent Therapy

  • At least 1 month since participation in another pharmacologic clinical trial.
  • At least 1 month since drugs that may affect splanchnic hemodynamics or portal pressure, e.g., beta-blockers, clonidine prazosin, nitrates molsidomine

Patient Characteristics

  • Life expectancy: At least 1 year
  • Other: Eligibility determined on an individual basis for the following: aortic valve stenosis, atrioventricular block, asthma, chronic obstructive pulmonary disease with positive bronchoconstrictive test, heart failure, hypersensitivity to beta-blockers, insulin-dependent diabetes, organic psychosis, peripheral vascular disease.
  • No alcohol intake during titration period.
  • No pregnant women.
  • Effective contraception required of fertile women.
