Efficacy of GZR/EBR in Early Chronic Hepatitis C in HIV/HCV Co-infected Patients (EARLY-HEP-C)

Inclusion Criteria:

• ≥18 years of age
• Patients with early chronic hepatitis C (Genotype 1 or 4) which is defined as chronic hepatitis C with known episode of AHC within the last 4 years including those who failed to PEG/RBV or those who never received therapy for AHC.

• No history of ascites, bleeding esophageal varices, hepatic encephalopathy, or other signs/symptoms of advanced liver disease
• Have liver disease staging assessment as follows: Fibroscan performed within 3 previous months of Day 1 of this study showing result <8 kPa
• Be HIV-1 infected, documented by any licensed rapid HIV test and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 p24 antigen, or plasma HIV-1 RNA viral load.
• Be on stable HIV Antiretroviral Therapy (ART) for at least 8 weeks prior to study entry using a dual NRTI backbone of tenofovir or abacavir

Exclusion Criteria:

• < 18 years of age
• Patients with chronic hepatitis C genotypes other than 1 or 4.
• History of ascites, bleeding esophageal varices, hepatic encephalopathy, or other signs/symptoms of advanced liver disease
• Have liver disease staging assessment as follows: Fibroscan performed within 3 previous months of Day 1 of this study showing result > 8kPa
• Not be HIV-1 infected, documented by any licensed rapid HIV test and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 p24 antigen, or plasma HIV-1 RNA viral load.
• Due to known or suspected drug-drug interactions, for the purpose of this study, the use of Non Nucleoside Reverse Transcriptase Inhibitors, Inhibitors or Protease Inhibitors against HIV will be not allow.
