The limit of detection for HCV RNA levels was 10 IU/mL and the LLOQ was 25 IU/mL. Data for post-treatment Weeks 36 and 48 were based on participants who had achieved virologic response (defined as HCV RNA levels \

The limit of detection for HCV RNA levels 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.

An AE was defined as any new unfavorable symptom, sign, or disease or worsening of a pre-existing condition that does not necessarily have a causal relationship with treatment. SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity; was life-threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization. Treatment-related AE was defined as an AE that had certain, probable, possible, or unknown relationship to study drug. For analysis purpose, participants were assigned to following 4 race/ethnicity cohorts: Black/African American, White/Caucasian, Latino and Non-Latino. Some participants were represented in more than one race/ethnicity cohort.

Participants belonging to Latino ethnicity, received daclatasvir (BMS-790052) 60 mg tablet orally once daily, along with pegylated-interferon alfa 2a solution for injection 180 μg/0.5 mL subcutaneously once weekly, and ribavirin 1000 mg per day for those weighing <75 kg or 1200 mg per day for those weighing ≥75 kg for a period of 24 weeks. Participants who achieved a virologic response (HCV RNA undetectable at both Weeks 4 and 12) completed therapy at Week 24 and were followed for 48 weeks of post-treatment follow-up. Participants who did not achieve the virologic response, continued to receive pegylated-interferon alfa 2a and ribavirin for additional 24 weeks (total treatment duration of 48 weeks), and were followed for 24 weeks of post-treatment follow-up. Dose modifications to pegylated-interferon alfa 2a and ribavirin were allowed to manage tolerability and AEs. This cohort included White/Caucasian and Black/African American participants.
