safety, antiviral activity and pk of mrd of bi 201335 in chronic hepatitis c patients both treatment naive and -experienced

Conditions: Hepatitis C, Chronic

Summary: this study will investigate safety, antiviral activity, and pharmacokinetics of bi 201335 na in hcv genotype 1 infected patients treated for 14 days monotherapy followed by bi 201335 na combination therapy with pegifn/rbv for an additional 14 days for treatment-naïve patients; or for 28 days as bi 201335 na combination therapy with pegifn/rbv for treatment-experienced patients. a secondary objective is to investigate antiviral activity, potential drug-drug interactions and safety of combination therapy of bi 201335 na and pegifn/rbv up to 28 days for treatment-naïve patients.
