研究概览
简要总结
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-072 and ribavirin (RBV) in treatment-naïve participants with genotype 1 chronic hepatitis C virus (HCV) infection.
详细描述
This was a Phase 2a multicenter, open-label, single arm, combination treatment study of a regimen of ABT-450/r/ABT-072, and ribavirin (RBV) in hepatitis C virus (HCV) genotype 1-(1a or 1b) infected treatment-naïve participants.
