Primary Outcome(s)
|
Primary end point(s): The primary efficacy endpoint will be the proportion of subjects in each treatment arm achieving SVR12 (defined as HCV RNA
|
Secondary Objective: 1.Evaluate the efficacy of the combination regimens of MK5172 & MK3682 with MK8742 (Part A only) or MK8408 (Parts A and B), +/- ribavirin (Part B), as assessed by the proportion of GT3-infected subjects in each arm achieving SVR24 defined as HCV RNA In Part B, this secondary objective will be evaluated within each GT3-infected subject population (treatment-naïve vs. treatment-experienced, HIV/HCV co-infected vs. mono-infected, and cirrhotic vs. non-cirrhotic) separately. In addition, the following objectives will be evaluated for the GT3-infected HIV co-infected population: 2.Among GT3-infected HIV-1 co-infected patients, evaluate the proportion of subjects who develop HIV-1 virologic failure (HIV-1 RNA 200 copies/mL, in subjects compliant with their HIV antiretroviral therapy). 3.Among GT3-infected HIV-1 co-infected patients, evaluate the effect of the study regimens on CD4+ T-cell counts.
