Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to explore the efficacy and safety of boceprevir -based triple therapy to rescue HCV genotype 1 (HCV GT1)/HBV dually infected patients refractory to previous peginterferon (PEG-IFN) plus ribavirin (RBV) combination therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Liver disease, especially viral hepatitis, is an important public health issue, which frequent leads to liver cirrhosis, hepatocellular carcinoma (HCC) and liver-related death. Around 340 to 400 million persons are infected with hepatitis B virus (HBV) and 130 to 210 million persons are infected with hepatitis C virus (HCV) worldwide, In Taiwan, the prevalence of HBV infection is 15-20%, and the prevalence of HCV infection is 2-5% in general population. Moreover, there are some HCV-hyperendemic areas in southern Taiwan with anti-HCV prevalence rate of as high as 30-40%.

HBV/HCV dual infections is not uncommon in HBV epidemic areas, such as Southeastern Asia, with a prevalence rate of 1.1% in southern Taiwan. Recent study showed that the risk of HCC incidence is even higher among HBV/HCV co-infected persons than those with HBV or HCV mono-infection, indicating the importance of disease control in this clinical setting.

The PEG-IFN/RBV has been effective in the treatment of HCV-dominant, treatment-naïve patients with HCV/HBV dual infections. For treatment-naive HCV genotype 1 (HCV GT1)/HBV co-infected patients, 48 weeks of peginterferon (PEG-IFN) plus ribavirin (RBV) could achieve an HCV sustained virological response (SVR) rate of 72%, which was comparable to 77% for patients with HCV GT1 monoinfection. For treatment-naive HCV GT2 or GT3 /HBV co-infected patients, 24 weeks of PEG-IFN plus RBV could achieve an HCV SVR rate of 83%, which was comparable to 84% for patients with HCV GT2/3 monoinfection . Furthermore, PEG-IFN plus RBV combination therapy could enhance seroclearance of hepatitis B surface antigen (HBsAg) with an HBsAg loss rate of upto 11%. Nevertheless, there is about 30% of HCV GT1/HBV and 20% of HCV GT2 or 3/HBV co-infected patients refractory to current PEG-IFN/RBV combination therapy, which remains at high risk of HCC and liver-related death.

Boceprevir is an oral antiviral drug, which is NS3/4A protease inhibitor. Boceprevir has been approved for treating HCV GT1 infection by Food and Drug Administration (FDA) on 11 May 2011. For HCV GT1 mono-infected patients who refractory to previous PEG-IFN plus RBV combination therapy, becoprevir combined with PEG-IFN/RBV triple therapy can improve the treatment efficacy. The SVR rate of becoprevir-based triple therapy is about 3 times when compared to patients who received PEG-IFN with RBV dual therapy \[14\].The investigators , therefore, hypothesize that boceprevir plus PEG-IFN/RBV is effective in treating HCV GT1/HBV dually infected patients who are refractory to previous PEG-IFN/RBV combination therapy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with 32 week therapy

For non-cirrhotic patients whose response of previous HCV therapy with PEG-IFN/RBV were relapse or partial response, PEG-IFN/RBV lead-in therapy is performed during 0-4 weeks, then add boceprevir from week 5 (boceprevir+ PEG-IFN/RBV). If HCV RNA is undetectable during 8-24 weeks, boceprevir+PEG-IFN/RBV triple therapy will be administered from week 5 to week 32.

Dosage of drugs: Boceprevir 800mg tid po, PegIntron 1.5 mcg/kg im QW, and Ribavirin 800 to 1400 mg/day PO divided BID Regimen adjusted according to body weight.

Stop trial intervention for patients with 32 week therapy: for all patients, if HCV RNA is more than 100 IU/ml at week 12 or HCV RNA is detectable at week 24, therapy will be stopped (Stop trial intervention for boceprevir, PEG-IFN and RBV for arm A).
