Cohort A
Participants with HCV GT-2 or GT-3 infection (Cohort A) were treated with Lambda/Ribavirin/Daclatasvir. Participants were administered daclatasvir 60 mg orally, once daily; peginterferon lambda-1a 180 microgram subcutaneous injection, once weekly and ribavirin tablets, orally, twice daily (a total 800 mg per day) for 12 weeks treatment, 12 weeks and a maximum of 12 weeks, respectively (treatment period= 12 Weeks). Participants were followed up for 24 weeks after administration of last treatment (follow-up period= 24 Weeks).

Cohort B
Participants with HCV GT-1b or GT-4 infection (Cohort B) were treated with Lambda/Ribavirin/Daclatasvir. Participants were administered daclatasvir 60 mg orally, once daily, peginterferon lambda-1a 180 microgram subcutaneous injection, once weekly and ribavirin tablets, twice daily, orally, based on weight (participants weighing \<75 kg = 1000 mg and participants weighing \>=75 kg = 1200 mg per day) for 12 weeks treatment, 24 weeks and a maximum of 24 weeks, respectively (treatment period= 24 Weeks).
