Title: Safety, Antiviral Effect and Pharmacokinetics of BI 207127 in Combination With BI 201335 and With or Without Ribavirin for 4, 16, 24, 28 or 40 Weeks in Patients With Chronic HCV Genotype 1 Infection (Randomized Phase Ib/II)
Brief Summary: The substances BI 201335 and BI 207127 are being developed for the treatment of chronic hepatitis C virus infection. BI 201335 and BI 207127 work by preventing the virus from replicating.

The currently available medications pegylated interferon alfa and ribavirin for hepatitis C ca have considerable adverse events in patients and in many cases are not sufficiently effective. This is particularly the case in treatment of patients infected with genotype 1 of HCV.

A combination therapy of these new substances without pegylated interferon alfa may be associated with fewer adverse events that currently available (pegylated interferon-alfa-based) medication and may also provide a treatment option to the large number of patients with contraindications or intolerance to pegylated interferon alfa.

This clinical trial (1241.21) currently consists of 3 distinct studies: Part 1, Part 2 and Part 3.

Part 1 (SOUND-C1) is a 2 armed study as described in experimental arms 1 and 2 below (actual enrollment: 56 patients; randomized and treated: 32) Part 2 (SOUND-C2) is a 5 armed study as described in experimental arms 3 to 7 below (actual enrollment: 465; randomized and treated: 362) Part 3 (SOUND-C3) includes 3 arms as described in experimental arms 8 to 10 below (83 patients randomized and treated)
