A Phase 2b Evaluation of Daclatasvir/Sofosbuvir in Non-Cirrhotic Treatment Naive Subjects With Genotype 1, 2, 3 and 4 Chronic Hepatitis C Virus Coinfected With Human Immunodeficiency Virus (HIV-1)

Sustained virologic response (SVR12) rate

SVR12 rate defined as HCV RNA \< lower limit of quantification (LLOQ) target detected (TD) or target not detected (TND) at follow-up Week 12 in subjects infected with HCV/HIV-1 coinfection, by individual genotype (1-4)

Time frame: Approximately 2 years

Treatment safety measured by the number of incidence of serious adverse event (SAEs), discontinuations due to adverse event (AEs), Grade 3/4 AEs and Grade 3/4 clinical laboratory abnormalities through the end of treatment

Time frame: Approximately 2 years

Proportion of subjects who achieve HCV RNA < LLOQ-TD/TND at each of the following Weeks: 1, 2, 4, 6, 8, EOT, post-treatment Week 4 in subjects on the 8-week regimen of DCV/SOF

Time frame: Approximately 2 years

Proportion of subjects who achieve HCV RNA < LLOQ TND at each of the following Weeks: 1, 2, 4, 6, 8, end of treatment (EOT), in subjects on the 8-week regimen of DCV/SOF

Time frame: Approximately 2 years

Proportion of subjects receiving cART who maintain HIV virologic suppression

Time frame: Approximately 2 years

Proportion of subjects receiving cART who experience HIV virologic failure

Time frame: Approximately 2 years
