Secondary	Mean Absolute Score of Beck Depression Inventory, Second Edition (BDI-II)	BDI-II is 21-item self-report instrument to assess severity of symptoms of depression. There is a four-point scale for each item ranging from 0 to 3. Degrees of depression defined by the total BDI-II score as: minimal (0 to 13), mild (14 to 19), moderate (20 to 28), and severe depression (>= 29). Higher scores reflective of greater severity (worse outcome).

There is a four-point scale for each item ranging from 0 to 3. Degrees of depression defined by the total BDI-II score as: minimal (0 to 13), mild (14 to 19), moderate (20 to 28), and severe depression (>= 29). Higher scores reflective of greater severity (worse outcome).

Secondary	Mean Absolute Scores for Hepatitis Quality-of-Life Questionnaire (HQLQ) at EOT (Week 24/48) Visit and 24 Weeks After EOT Visit	The HQLQ is a multiple-choice questionnaire includes the eight individual qualify-of-life scales of the Medical Outcomes Study 36-item Short-form Health Survey as: Social functioning (SF), role limitations due to emotional problems (RE), vitality (VT), general mental health (MH), physical functioning (PF), role limitations due to physical problems (RP), freedom from bodily pain (BP), and general health (GH). In addition, two other generic scales (positive well-being [PWB] and health distress [HD]) and two hepatitis-specific scales (limitations because of chronic hepatitis C [HLIM] and health distress because of chronic hepatitis C [HHD]) were included. Scores were scaled to a 0 to 100 range, with 0 = bad and 100 = good. A higher score indicates an improvement.

Secondary	Number of Participants With Marked Laboratory Abnormalities (Hematology)	Hematology included hematocrit (fraction), hemoglobin, platelets count, Red blood cells (RBC), White blood cell (WBC), eosinophils, lymphocytes, monocytes, neutrophils, Partial Thromboplastin time (PTT), Prothrombin Time International Normalized Ratio (PT INR). Laboratory values falling outside the marked reference range as defined by Roche's "International Guideline for the Handling and Reporting of Laboratory Data", and were clinically relevant change from baseline were considered marked laboratory abnormalities. It was reported as low or high abnormal.	Up to 24 weeks post treatment (Week 48 for G2/3 and Week 72 for G1)	No
Secondary	Number of Participants With Marked Laboratory Abnormalities (Biochemistry)	Laboratory values falling outside the marked reference range as defined by Roche's "International Guideline for the Handling and Reporting of Laboratory Data", and were clinically relevant change from baseline were considered marked laboratory abnormalities.

Secondary	Number of Participants With Any Adverse Events (AEs), Any Serious Adverse Events (SAEs), and Study Discontinuation	An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered to be related to the medicinal product. An SAE is any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or results in a congenital anomaly/birth defect. Reason for discontinuation was categorized as safety and non-safety, where safety reasons included abnormality of laboratory tests, AEs, and death; and non-safety reasons included insufficient therapeutic response, early improvement, violation of selection criteria at entry, other protocol violation, refused treatment, failure to return and other. Participants who discontinued the study with any reason were recorded.	Up to 24 weeks post treatment (Week 48 for G2/3 and Week 72 for G1)	No
