Study of Bavituximab in Patients With Chronic Hepatitis C Virus Infection

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the safety and tolerability of bavituximab when administered via a vein as a single infusion and to examine how bavituximab behaves in the body and how it affects the amount of hepatitis C virus in individuals with chronic infection.

Detailed Description
-----------------
Hepatitis C virus (HCV) infection is a world wide public health concern and is the most common chronic bloodborne infection in the United States and the leading indication for liver transplantation. Laboratory and animal studies have demonstrated that bavituximab binds viruses and virally infected cells and prolongs survival in infected animals. This study will examine the safety and tolerability of bavituximab when administered to patients with chronic HCV infection who do not respond to or relapse after treatment with pegylated interferon plus ribavirin combination therapy. Groups of patients will be treated with escalating doses and followed for 12 weeks.
