  • Virological Response 4 Weeks After the End of Treatment With BI 201335 or Placebo [ Time Frame: Week 28 ] [ Designated as safety issue: No ]

    An achieved virological response is defined as the plasma Hepatitis C Virus RiboNucleic Acid (HCV RNA) level below the lower limit of detection (BLD).

    This data was only collected for patients, who stopped trial participation at Week 24 and did not continue with PegIFN/RBV until Week 48.

    The lower limit of quantification (BLQ) of this assay was 25 IU/mL and the lower limit of detection (BLD) was 10 IU/mL at the time of the protocol finalisation. During the course of the trial, the manufacturer defined BLD as '< 25 IU/mL, not detectable' and BLQ as '< 25 IU/mL, detectable'.

  • Sustained Virological Response 24 Weeks (SVR24) After Completion of All Therapy [ Time Frame: Day 155 after the end of all treatment ] [ Designated as safety issue: No ]

    Virological (VL) response was defined as the plasma HCV RNA level below the lower limit of detection.

    The first VL measurement that occurred in the time window ≥ Day 155 (from End Of Treatment on) was selected for the determination of SVR24.

    Therefore, patients with virological load BLD 24 weeks after completion of therapy, who had a rebound after this time point (outside the defined time window of 155 days after end of all treatments) were identified as SVR24 achieved.

Antiviral Effect, Safety, and Pharmacokinetics of BI201335 +PegIFN/RBV in HCV-GT1 (SILEN-C1&2)
Antiviral Effect, Safety and Pharmacokinetics of BI 201335 NA in Hepatitis C Virus Genotype 1 Infected Treatment-naïve and Treatment-experienced Patients for 24 Weeks as Combination Therapy With Pegylated Interferon-alpha 2a and Ribavirin (Double-blinded, Randomised, Placebo-controlled, Phase II)
The objective was to investigate the antiviral effect, safety, and pharmacokinetics of BI 201335 (Faldaprevir), given as a soft gelatine capsule, in patients with hepatitis C virus (HCV) genotype 1 infection. Combination therapy of BI 201335 (Faldaprevir) with pegylated interferon α-2a (PegIFN) and ribavirin (RBV), with or without a 3-day lead-in, was assessed in treatment-naïve (TN) and treatment experienced (TE) patients.
