Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieved Sustained Virologic Response (SVR) 12 Weeks After the End of Treatment (SVR12)12 weeks after the end of treatment

SVR12 was defined as hepatitis C virus (HCV) RNA laboratory value below the level of quantification (\< LOQ; i.e., 25 IU/ml) 12 weeks after the end of treatment.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Rapid Virologic Response (RVR) After 4 Weeks of Treatment (RVR4)after 4 weeks of treatment

RVR4 was defined as serum HCV RNA \< LOQ after 4 weeks of treatment.

Percentage of Participants With Complete Early Virologic Response (cEVR) After 12 Weeks of Treatmentafter 12 weeks of treatment

cEVR was defined as serum HCV RNA \< LOQ after 12 weeks of treatment.

Percentage of Participants With Grade 3 or 4 Neutropenia During Treatment Within 48 Weekswithin 48 weeks

Grading was according to the DMID Toxicity Tables (version 2.0). Participants with multiple abnormalities were counted only once in the worst category.

Percentage of Participants With Early Virologic Response (EVR) After 12 Weeks of Treatmentafter 12 weeks of treatment

EVR was defined as a ≥ 2 log10 decrease in HCV RNA or HCV RNA \< LOQ after 12 weeks of treatment.

Percentage of Participants With Partial Early Virologic Response (pEVR) After 12 Weeks of Treatmentafter 12 weeks of treatment

pEVR was defined as a ≥ 2 log10 decrease in HCV RNA and still detectable (≥ LOQ) after 12 weeks of treatment.

Percentage of Participants With Extended Rapid Virologic Response (eRVR) From 4 to 12 Weeks of Treatmentfrom 4 to 12 weeks of treatment

eRVR was defined as achieving RVR4 and maintaining HCV RNA \< LOQ until Week 12.

Percentage of Participants With End of Treatment Response (ETR) at Treatment End Within 48 Weeksat treatment end within 48 weeks

ETR was defined as serum HCV RNA \< LOQ at treatment end (completed or prematurely discontinued).

Percentage of Participants With Alanine Aminotransferase (ALT) Abnormalities Within 48 Weekswithin 48 weeks

ALT abnormalities were summarized as participants who had either:

* ALT \> 2 x upper limit of normal (ULN) during the study and \> 2 x ULN at baseline

* ALT \> 3 x ULN during the study and \> 2 x ULN at baseline

Percentage of Participants With Grade 3 or 4 Anemia During Treatment Within 48 Weekswithin 48 weeks

Grading was according to the Modified Division of Microbiology \& Infectious Diseases (DMID) Toxicity Tables (version 2.0).

Participants with multiple abnormalities were counted only once in the worst category.

Percentage of Participants Who Achieved SVR 24 Weeks After the End of Treatment (SVR24)24 weeks after the end of treatment

SVR24 was defined as HCV RNA laboratory value \< LOQ 24 weeks after the end of treatment.

Percentage of Participants With Grade 3 or 4 Thrombocytopenia During Treatment Within 48 Weekswithin 48 weeks

Grading was according to the DMID Toxicity Tables (version 2.0). Participants with multiple abnormalities were counted only once in the worst category.
