  1. Percentage of Participants With Sustained Virological Response by Type of Peginterferon and Genotype in Modified All Treated Population

    Sustained virological response (SVR) was defined as virological response (VR) at 24 weeks after end of treatment (EOT).

Virological Response (VR) was defined as HCV RNA \<15 IU/mL as assessed by COBAS AmpliPrep/COBAS TaqMan (HCV) (CAP/CTM) or another HCV RNA test with at least the same degree of sensitivity. The CAP/CTM test is an in vitro nucleic acid amplification test for the quantification of HCV. This test possesses a high sensitivity (lower limit of detection 15 IU/mL) and a broad linear range of quantification (43 IU/mL up to 69 million IU/mL) in all HCV genotypes.

Modified virological response (mVR) was defined as HCV RNA \<50 IU/mL as assessed by CAP/CTM or another HCV RNA test with at least the same degree of sensitivity. The CAP/CTM test is an in vitro nucleic acid amplification test for the quantification of HCV. This test possesses a high sensitivity (LLOD 15 IU/mL) and a broad linear range of quantification (43 IU/mL up to 69 million IU/mL) in all HCV genotypes. The mVR is reported in treatment naive HCV mono-infected mTRT population who received PEG-IFN alfa-2a and PEG-IFN alfa-2b. The EOT was 12, 24, 48 or 72 weeks after initiation of treatment.

The probability that a participant who failed to develop VR by Wk 4 and 12 and also failed to achieve mSVR at 24 weeks after EOT was called the NPV of the VR by Wk 4 and 12 for mSVR. Predictive Values of VR was reported in treatment naive HCV mono-infected mTRT population participants who received PEG-IFN alfa-2a and PEG-IFN alfa-2b.

SecondaryPercentage of Participants With Predictive Values of Virological Response on Modified Sustained Virological Response After Treatment Initiation in Per Protocol Population

The probability that a participant who developed VR by Wk 2 and achieved mSVR at 24 weeks after EOT was called the PPV of the VR by Wk 4 for mSVR. The probability that a participant who failed to develop VR by Wk 2 and also failed to achieve mSVR at 24 weeks after EOT was called the NPV of the VR by Wk 2 for mSVR. Predictive values of VR is reported in treatment naive HCV mono-infected PP population who received PEG-IFN alfa-2a and PEG-IFN alfa-2b. The EOT was 12, 24, 48 or 72 weeks after initiation of treatment.

SecondaryPercentage of Participants With Relapse After Modified End of Treatment Response by Genotype in Modified All-Treated Population at 12 Weeks After End of Treatment

Participants whose last test result in their respective follow-up time window showed mVR were considered to have maintained their modified end of treatment response (mEOT-R). Participants whose last test result in the respective follow-up time window did not show mVR, or who did not have a test result in the respective follow-up time window but whose last follow-up test result before the time window did not show mVR, were considered to have relapsed. Only participants with mEOT-R who had a HCV RNA measurement in the follow-up time window (without use of backward imputation), or whose last HCV RNA measurement at a follow-up time point before the time window did not show mVR, were included in the calculations. The number of participants with relapse was reported in treatment naive mTRT population who received PEG-IFN alfa-2a and PEG-IFN alfa-2b. The EOT was 12, 24, 48 or 72 weeks after initiation of treatment.
