简要总结

A Phase 2b, Open-Label, Randomized Study of the Safety, Tolerability, and Pharmacodynamic Activity of Lonafarnib With or Without Ritonavir in Patients Chronically Infected with Hepatitis Delta Virus

详细描述

This Phase 2b, randomized, open-label study will assess the safety, tolerability, and pharmacodynamics (PD)/efficacy of 48 weeks of lonafarnib (LNF) and ritonavir (RTV) combination therapy vs. LNF monotherapy in patients with chronically infected with Hepatitis Delta Virus (CHD). Sixty patients will be enrolled at a single study site. Eligible patients will have CHD infection (≥ 6 months) confirmed by positive HDV antibody (Ab) test and HDV RNA ≥ 3 lg IU/mL by quantitative polymerase chain reaction (qPCR) at study entry.

•Alpha-fetoprotein ≥ 100 ng/mL
•Evidence of another form of viral hepatitis or another form of liver disease (eg, autoimmune liver disease, primary biliary cirrhosis, primary sclerosing cholangitis, Wilson's disease, alcoholic liver disease, nonalcoholic steatohepatitis, hemochromatosis, alpha-1-anti-trypsin deficiency)
•History of hepatocellular carcinoma
•Patients with any of the following:
•Current eating disorder or alcohol abuse
•Excessive alcohol intake, defined as follows:
•> 20 g/day for females (1.5 standard alcohol drinks) or
•> 30 g/day for males (2.0 standard alcohol drinks).
•A standard drink contains 14 g of alcohol: 360 mL of beer, 150 mL of wine, or 45 mL of spirits
