| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To determine the durability of virologic response in subjects treated in a previous study with Lambda (BMS-91413) with or without ribavirin (RBV) and/or Direct Acting Antivirals (DAA), who have HCV RNA less than the limit of quantitation of the assay (< LOQ) at the completion of the required post-treatment follow-up in the previous (parent) study. |  | 
| E.2.2 | Secondary objectives of the trial | 
| • To characterize the long-term progression of liver disease, as measured by laboratory indicators of hepatic status and function, all-cause mortality, and liver-related mortality, among subjects previously treated with Lambda, with or without RBV and/or DAAs, who have HCV RNA < LOQ at the completion of the required post-treatment follow-up in the parent study; • To determine the duration of persistence of anti-Lambda antibodies in subjects who are positive for anti-Lambda antibodies at end of treatment (EOT) in the parent study.
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| Subjects must have received BMS-914143 in a previous trial and have HCV RNA < LOQ at the completion of the required post-treatment follow-up (must enter this study within 6 months of completion of the required post-treatment follow-up in the previous trial). |  | 
| E.4 | Principal exclusion criteria | 
| Subjects must not have been treated with any antiviral or immunomodulatory drug for hepatitis C after completion of the previous study of BMS-914143. |  | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| The durability of virologic response in subjects treated in a previous study with BMS-914143 who have HCV RNA less than the limit of quantitation of the assay (< LOQ) at the completion of the required post-treatment follow-up in the previous study. |  | 
| E.5.1.1 | Timepoint(s) of evaluation of this end point | 
| Loss of virologic response assessed using HCV RNA at 24-week intervals. |  | 
| E.5.2 | Secondary end point(s) | 
| In subjects previously treated with BMS-914143 who have HCV RNA < LOQ at the completion of the required post-treatment follow-up in the parent study: - long-term progression of liver disease, all-cause mortality, and liver-related mortality
 - duration of persistence of anti-Lambda antibodies in subjects who are positive for anti-Lambda antibodies at end of treatment in the parent study.
