The 12-week interferon- and ribavirin (RBV)-free regimen included antiretroviral agents for 37 of the 50 patients (tenofovir and emtricitabine along with efavirenz [n = 15], raltegravir [n = 10], rilpivirine [n = 8], rilpivirine plus raltegravir [n = 3], or efavirenz plus raltegravir [n = 1].\u003C\/p\u003E\u003Cp id=\u0022p-5\u0022\u003EThe primary end point was SVR12. Safety end points included adverse events and discontinuations, HIV breakthrough evident as \u0026gt; 400 HIV RNA copies\/mL, CD4 T-cell counts and T-cell percentage, and renal parameters. Viral kinetics during the first 36 hours of treatment were charted in 10 patients in each group. The groups were comparable at baseline concerning median age, median HCV RNA, and prevalence of interleukin 28B non-CC genotype but differed in prevalence of males and African Americans, prevalence of genotype 1a, and prevalence of stage 3 fibrosis.\u003C\/p\u003E\u003Cp id=\u0022p-6\u0022\u003EBoth groups displayed a pronounced treatment response, with 100% of patients in both groups having HCV RNA below the level of detection at 4 weeks of treatment.
