Once-daily simeprevir (TMC435) with peginterferon/ribavirin for treatment-naive hepatitis C genotype 1-infected patients in Japan: the DRAGON study.

ABSTRACT:

Background

Efficacy, safety and pharmacokinetics of simeprevir (TMC435), a once-daily, noncovalent, oral hepatitis C virus (HCV) NS3/4A protease inhibitor, was evaluated in combination with peginterferon α-2a/ribavirin (PegIFNα-2a/RBV) for treatment-naïve, HCV genotype 1-infected patients in Japan.

Methods

In a multicenter, randomized clinical trial in Japan, ninety-two patients received either simeprevir (50 or 100 mg QD) for 12 or 24 weeks with PegIFNα-2a/RBV for 24 or 48 weeks (according to response-guided therapy [RGT] criteria), or PegIFNα-2a/RBV for 48 weeks (PR48 group).

Results

Compared with the PR48 group, plasma HCV RNA reductions in the simeprevir groups were rapid and more substantial (Week 4: -5.2, -5.2 and -2.9 log10IU/mL for simeprevir 50 mg combined, 1
