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)
