Title: Safety, Antiviral Activity, and Pharmacokinetics of BI 207127 NA Administered in Combination With Peg-IFN and Ribavirin in Chronic HCV-infected Patients for 4 Weeks, a Randomised, Double-blind, Placebo Controlled Study
Brief Summary: The main purpose of this clinical trial with BI 207127 is to see the effect of 4 week combination of BI 207127 with Peginterferon alfa (Peg-IFN) and Ribavirin (RBV) on hepatitis C virus (HCV) virus load and how safe BI 207127 is in this combination in HCV infected patients.

* Active alcohol or substance abuse sufficient, in the Investigator's judgment, to prevent adherence to study medication and/or follow up.
* Pregnant or nursing females.
* Males whose female partner is pregnant.
D: Inclusion Criteria:

* Subjects must have a qualifying regimen defined as peginterferon alfa-2a/ribavirin or peginterferon alfa-2b/ribavirin for a minimum of 12 weeks.
* During the qualifying regimen, subjects must have either:

  * A documented undetectable Hepatitis C Virus-Ribonucleic Acid (HCV-RNA) within 30 days of the end-of-treatment and a subsequent detectable HCV-RNA during follow-up OR
  * A documented decline in HCV-RNA by \>=2 log10 after 12 weeks of treatment.
* Subject must have previously documented chronic hepatitis C genotype 1 infection.
* Subject must have a liver biopsy with histology consistent with chronic hepatitis C infection and no other etiology.
* Subjects with bridging fibrosis or cirrhosis must have an ultrasound within 6 months with no findings suspicious for hepatocellular carcinoma (HCC).
