Primary Outcome Measures:
  • Incidence of Serious Adverse Events (SAEs) and/or Clinically Significant Adverse Events (AEs) [ Time Frame: Up to 12 Weeks ]
    An AE was any untoward medical occurrence in a participant administered a medicinal product which did not necessarily have a causal relationship to the treatment. All AEs reported in the study were judged by the investigator to be clinically significant. An SAE was any adverse drug experience that resulted in death, was life-threatening, caused or prolonged hospitalization, caused persistent or significant disability or incapacity, caused a congenital anomaly or birth defect, or may have required medical or surgical intervention to prevent one of these outcomes.

  • Incidence of Thrombocytopenia [ Time Frame: Up to 12 Weeks ]
    Thrombocytopenia is a low blood platelet count

  • Incidence of Treatment Discontinuations Due to Adverse Events [ Time Frame: Up to 12 Weeks ]
    All treatment discontinuations due to an AE were reported. See Outcome Measure 1 for definition of AEs.

  • Incidence of Particular Adverse Events Resulting in Treatment Discontinuation [ Time Frame: Up to 12 Weeks ]

    All treatment discontinuations due to particular AEs were reported. These discontinuations included treatment stopped (TS) and dose reduced followed by treatment stopped (DR/TS).

    The particular AE evaluated were anemia (low red blood cells), leucopenia (low white blood cells), neutropenia (low blood neutrophils), thrombocytopenia (low blood platelets), esophageal varices (dilated veins in lower esophagus), splenomegaly (enlarged spleen), portal hypertensive gastropathy (changes in stomach mucosa), and hepatomegaly (enlarged liver)


  • Incidence of Dose Modifications Due to Adverse Events [ Time Frame: Up to 12 Weeks ]
    All dose modifications due to an AE were reported. See Outcome Measure 1 for definition of AEs.


Secondary Outcome Measures:
  • Proportion of Participants Who Achieve Undetectable Hepatitis C Virus Ribonucleic Acid (HCV-RNA) [ Time Frame: Week 12 ]
    Participant's blood was tested for HCV-RNA by quantitative polymerase chain reaction. The limit of detection for the assay was 50 IU/mL.
