SVR12, defined as percentage of participants with hepatitis C virus (HCV) ribonucleic acid (RNA) \< lower limit of quantitation (LLOQ), target detected (TD) or target not detected (TND) at follow-up Week 12. SVR12 imputation was based on Next Value Carried Backwards (NVCB) approach. HCV RNA measurements were excluded after the start of non-study anti-HCV medication on treatment or during follow-up.

SVR12 was defined as hepatitis C Virus (HCV) RNA levels below the lower limit of quantitation (\<LLOQ) i.e., 25 IU/mL target detected or target not detected, at post-treatment Week 12. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory. For participants who missed the follow-up Week 12 visit, SVR12 was imputed using the next and closest available HCV RNA measurement after the follow-up Week 12 window.

SVR12 was defined as Hepatitis C Virus (HCV) RNA levels \<lower limit of quantitation (LLOQ), (target detected or target not detected) at Post-treatment Week 12. The limit of detection for HCV RNA was 10 IU/mL and the LLOQ was 25 IU/mL. For analysis purpose, participants were assigned to following 3 race/ethnicity cohorts: Black/African American, Latino, and White non-Latino. Some participants were represented in more than one race/ethnicity cohort.

SVR12 rate was defined as hepatitis C virus (HCV) RNA levels to be \<lower limit of quantitation, target detected or target not detected, at post-treatment Week 12. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

SVR12 defined as HCV RNA\<limit of quantitation at follow-up Week 12. Nonresponder (NR)=prior NR to pegIFN-2a or ribavirin.

SVR24 was defined as undetectable HCV RNA (HCV RNA \<lower limit of quantitation \[LLOQ\], target not detected \[TND\]) at follow-up Week 24. The LLOQ was 25 IU/mL, and \<LLOQ, TND was 10 IU/mL. HCV RNA levels were measured by the Roche COBAS® TaqMan® HCV Test version 2.0 from the central laboratory.

SVR24 was defined as undetectable HCV RNA (HCV RNA \<lower limit of quantitation \[LLOQ\], target not detected \[TND\]) at follow-up Week 24. The LLOQ was 25 IU/mL, and \<LLOQ, TND was 10 IU/mL.

eRVR was defined as HCV RNA \<lower limit of quantitation and target not detected at both Weeks 4 and 12 on treatment.

SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity, or drug dependency/abuse; was life threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization.

eRVR was defined as undetectable hepatitis C virus (HCV) RNA ie, HCV RNA \<15 IU/mL, the lower limit of detection at both Weeks 4 and 12.

eRVR was defined as undetectable hepatitis C virus RNA less than the lower limit of detection (10 IU/mL) at Weeks 4 and 12.

The Roche TaqMan HCV quantitative assay was used for analysis with detection limit of 10 IU/mL. Baseline was Day -1.

Cmax was obtained from concentration-time plot using a noncompartmental method and a validated pharmacokinetic analysis program.

AUC(TAU) was the area under the curve from time zero to end of dosing interval. AUC(TAU) was obtained from concentration-time plot of daclatasvir using noncompartmental method and a validated pharmacokinetic analysis program.

AUC(INF) was estimated by summing the area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration and the extrapolated area, computed by the quotient of the last observable concentration and elimination rate constant. The pharmacokinetic (PK) analysis was based on Cockcroft-Gault (C-G) creatinine clearance (CLcr) grouping method: normal renal function, end stage renal disease (ESRD), moderate and severe renal impairment. Mild participants were counted as per their original allocation.

AEs were defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding) or disease which either occurs during study, whether or not related to the study drug. SAEs were defined as any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgement of investigators represent significant hazards.

Participants were assessed by investigator for any clinically significant changes in vital parameters like body temperature, respiratory rate, blood pressure, heart rate and weight. The assessment was performed by a calibrated sphygmomanometer and thermometer for blood pressure and temperature, respectively. Blood pressure and heart rate were measured after at least 5 minutes quiet seating of the subject. Weight was measured at the discharge. The criteria for clinically significant change was as per the investigators discretion.

Laboratory marked abnormalities were defined as Hematocrit (low) as \<0.85\*pre-treatment value, Leukocytes (low) as \<0.9\*lower limit of normal, Aspartate Aminotransferase (high) as \>1.25\*upper limit of normal, Creatinine (high) as \>1.33\*pre-treatment value, Bicarbonate (high) as \>1.2\*upper limit of normal, Total Protein (high) as \>1.1\*upper limit of normal, Creatinine Kinase (high) as \>1.5\*upper limit of normal, Blood in Urine (high) as ≥ 2\*upper limit of normal. Participants were fasted for at least 10 hours prior to the collection of blood specimens for clinical laboratory tests.
