Secondary Prophylaxis of Gastrointestinal Bleeding in Cirrhotic Patients Using THALIDOMIDE

Withdrawn before enrolling · Phase 3

Conditions studied: Gastrointestinal Hemorrhage, Portal Hypertension

In brief

The natural history of cirrhosis has a symptomatic and asymptomatic stage. The symptoms include the development of ascites, hepatic encephalopathy, or variceal bleeding. The development of portal hypertension represents a critical transition point in the natural history of cirrhosis, contributing to, or directly responsible for all of these events. It is defined by an increase in intrahepatic vascular resistance to portal venous inflow, with the subsequent development of collateral vessels, such as esophageal or gastric varices. As portal pressures rise over time, however, the resulting increase in variceal size and wall tension translates into an increasing likelihood of rupture and bleeding, leading to death in about 30% of patients. Over the last twenty years, data have emerged regarding the role of tumor necrosis factor (TNFα) in portal hypertension from animal models as well as in vitro experiments. Portal hypertension is a condition characterized by vasodilatation and a hyperdynamic circulation, driven by relative overproduction of nitric oxide23. In animal trials using inhibitors of TNF it has been shown to decrease the development of the hyperdynamic circulatory state and portal pressure.24-25 Based on these data, investigators have examined the role of TNF inhibition with thalidomide. Significant improvement in blocking the development of the hyperdynamic circulation and portal pressures was demonstrated.26 Human trials have also show the efficacy of thalidomide in reducing portal pressures. In that these trials have shown promising results further investigation is
