Primary Outcome Measures

  • Antiviral activity, as determined by the proportion of subjects with SVR12, defined as HCV RNA [ Time Frame: Post treatment Week 12 ]
    SVR=Sustained virologic response HCV=Hepatitis C virus RNA=Ribonucleic acid LLOQ=Lower Limit of Quantification
Secondary Outcome Measures:
  • Proportion of subjects with Rapid virologic response (RVR) and Extended Rapid Virologic Response (eRVR), where RVR is defined as [ Time Frame: RVR at Week 4 and eRVR at Weeks 4 and 12 ]
  • Proportion of subjects in each group/duration who achieve HCV RNA [ Time Frame: 24 weeks post treatment (SVR24) ]
  • Proportion of subjects with treatment emergent cytopenic abnormalities (anemia as defined by Hb <10 g/dL, and/or neutropenia as defined by ANC <750 mm3 and/or thrombocytopenia as defined by platelets <50,000 mm3) during the treatment period [ Time Frame: Weeks 1, 2, 4, 6, 8, 12, 20, and 24 (and Weeks 28, 32, 36, 40, 44, and 48 for subjects requiring those visits) ]
    Hb=Hemoglobin ANC=Absolute Neutrophil Count
  • Proportion of subjects with the following on treatment IFN-associated symptoms: flu-like symptoms (as defined by pyrexia or chills or pain) and musculoskeletal symptoms (as defined by arthralgia or myalgia or back pain) [ Time Frame: Weeks 1, 2, 4, 6, 8, 12, 20, and 24 (and Weeks 28, 32, 36, 40, 44, and 48 for subjects requiring those visits) ]
  • Frequency of deaths, serious adverse events (SAEs), discontinuations due to Adverse Events (AEs), dose reductions, and severity Grade 3/4 laboratory abnormalities [ Time Frame: From Day 1 until the end of treatment 24 weeks or 48 weeks: Weeks 1, 2, 4, 6, 8, 12, 20, and 24 (and Weeks 28, 32, 36, 40, 44, and 48 for subjects requiring those visits) ]
  • Absolute and percent change from baseline in the CD4 cell count, lymphocyte cell count, and platelet count [ Time Frame: Weeks 4, 8, 12 and 24 (and Week 36 for subjects requiring visit) ]

Detailed Description:

Study Classification: Safety/Efficacy and Pharmacokinetics/dynamics



Ages Eligible for Study: 18 Years and older  
Sexes Eligible for Study: All  
Accepts Healthy Volunteers: No  


Inclusion Criteria:

  • HCV Genotype-1, -2, -3 or -4 treatment naïve;
  • HCV RNA ≥10,000 IU/mL at screening;
  • HIV-1 infection [(approximately 200 subjects receiving HAART, approximately 100 subjects not receiving highly active antiretroviral therapy (HAART)];
  • For subjects receiving HAART, HIV RNA must be below <40 copies/mL at screening and <200 copies/mL for at least 8 weeks prior to screening;
  • CD4 cell count at screening must be ≥100 cells/μL if receiving HAART or ≥350 cells/μL if not receiving HAART)
  • Seronegative for Hepatitis B Surface Antigen (HBsAg)
  • Body Mass Index (BMI) of 18 to 35 kg/m2, inclusive. BMI=weight (kg)/[height (m)]2 at screening;
  • Subjects with compensated cirrhosis are permitted, but the number of subjects will be capped at approximately 30%. If a subject does not have cirrhosis, a liver biopsy within 3 years prior to enrollment is required to demonstrate the absence of cirrhosis. If cirrhosis is present, any prior liver biopsy is sufficient. Fibroscan® or FibroTest are acceptable if performed within 1 year prior to treatment in countries where liver biopsy is not required prior to treatment and where non-invasive imaging tests are approved for staging of liver disease
  • Subjects with mild to moderate hemophilia as defined as:
    1. Mild-factor level activity of 6-4% OR
    2. Moderate defined as factor level activity of 1-5%

Exclusion Criteria:
  • Any evidence of liver disease other than chronic HCV;
  • Subjects infected with human immunodeficiency virus (HIV-2);
  • Diagnosed or suspected hepatocellular carcinoma;
  • Decompensated liver disease;
  • Presence of acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections within 12 weeks prior to study entry (AIDS-defining opportunistic infections as defined by the CDC, (CDC, JAMA 1993 Feb 10;269(6):729-30)
  • Laboratory values: ANC <1.5 x 109 cells/L (<1.2 x 109 cells/L for Blacks), platelet count <90 x 109 cells/L, hemoglobin <11 g/dL for females, hemoglobin <12 g/dL for males;
  • Subjects (receiving HAART) who had first initiated anti-retroviral therapy within last 8 weeks prior to Day 1; however, if changes are required to a subject's HAART regimen to meet the requirements of the protocol, these changes are allowed at the screening visit. Subjects should wait a minimum of 1 month prior to Day 1 after a repeat of HIV viral load has been confirmed, <40 copies/mL
  • Subjects on Zidovudine (AZT), Didanosine (ddI), or Stavudine (d4T);
  • Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements
  • Subjects with severe hemophilia (defined as <1% factor activity level)
