SVR at follow-up Week 4 (SVR4), follow-up Week 12 (SVR12), and follow-up Week 24 (SVR24) is defined as undetectable hepatitis C virus (HCV) RNA (ie, HCV RNA <15 IU/mL, the lower limit of detection, target not detected) at each of these timepoints. HCV RNA levels were measured by Cobas TaqMan HCV Auto from the central laboratory .

Virologic failure is defined by the following 6 categories: 1.Virologic breakthrough, defined as confirmed >1 log10 increase in hepatitis C virus (HCV) RNA over nadir or confirmed HCV RNA ≥limit of quantitation (LOQ) after confirmed undetectable HCV RNA while on treatment. 2. <1 log10 decrease in HCV RNA from baseline at Week 4 of treatment. 3. Failure to achieve early virologic response, defined as <2 log10 decrease in HCV RNA from baseline at Week 12 of treatment. 4. Detectable HCV RNA at Week 12, and HCV RNA ≥LOQ at Week 24 of treatment. 5. Detectable HCV RNA at end of treatment (including early discontinuation). 6 Relapse, defined as detectable HCV RNA during follow-up after undetectable HCV RNA levels at end of treatment.

Clinically significant marked abnormalities in laboratory test results graded by the Division of AIDS grading table, 2004. Hemoglobin: Grade 3= <7.0 to 8.9 g/dL, Grade 4= <7.0 g/dL. Lymphocytes: Grade 3= 350-499 cells/mm^3, Grade 4= <350 cells/mm^3. Neutrophils: Grade 3= 500-999 cells/mm^3, Grade 4= <500 cells/mm^3. White blood cells (WBC): Grade 3= 1000-1499 cells/mm^3, Grade 4= <1000 cells/mm^3. Alanine aminotransferase (ALT): Grade 3= 5.1-10*upper limit of normal (ULN), Grade 4= >10.0*ULN. Aspartate aminotransferase (AST): Grade 3= 5.1-10*ULN, Grade 4= >10.0*ULN. Total bilirubin: Grade 3= 2.6-5*ULN, Grade 4= >5.0*ULN.

Participants received 10 mg of daclatasvir, once daily, coadministered with ribavirin, twice daily, and peginterferon alpha-2b (pegIFNα) injection, once weekly. Treatment-naive participants were those who had never been exposed to any hepatitis C virus (HCV) therapy with interferon IFNα-containing regimens, including pegIFNα/ribavirin.
