Outcome Measures

Primary Outcome Measures

  1. Percentage of Participants With Sustained Virological Response (SVR) at 12 Weeks After End of Treatment (EOT) [At 12 weeks after EOT (up to 60 weeks)]

    SVR at 12 weeks after EOT was defined as an undetectable HCV RNA viral load obtained 12 weeks following completion of treatment. HCV RNA viral load was measured using the Roche COBAS TaqMan 2.0 HCV Test, with a lower limit of detection (LOD) of 10 to 15 international units per milliliter (IU/mL). The percentage of participants with SVR was calculated as [number of participants with undetectable HCV RNA at 12 weeks after EOT divided by the number of participants analyzed] multiplied by 100.

Secondary Outcome Measures

  1. Percentage of Participants With SVR at 24 Weeks After EOT [At 24 weeks after EOT (up to 72 weeks)]

    SVR at 24 weeks after EOT was defined as an undetectable HCV RNA viral load obtained 24 weeks following completion of treatment. HCV RNA viral load was measured using the Roche COBAS TaqMan 2.0 HCV Test, with a lower LOD of 10 to 15 IU/mL. The percentage of participants with SVR was calculated as [number of participants with undetectable HCV RNA at 24 weeks after EOT divided by the number of participants analyzed] multiplied by 100.

  2. HCV RNA Levels [At Baseline; Weeks 2, 4, 6, 8, 12, 16, 24, 28, and 36; EOT; and 12 and 24 weeks after EOT (up to 72 weeks)]

    HCV RNA levels were obtained routinely during and after treatment. Mean HCV RNA levels were calculated by averaging the HCV RNA levels among all participants analyzed at each collection timepoint and expressed in log10 IU/mL.

  3. Percentage of Participants With Virological Response [At Weeks 2, 4, 6, 8, 12, 16, 24, 28, and 36; and EOT (up to 48 weeks)]

    HCV RNA levels were obtained routinely during and after treatment. The percentage of participants with undetectable HCV RNA viral load (ie, virological response) was calculated as [number of participants with undetectable HCV RNA at each timepoint divided by the number of participants analyzed] multiplied by 100.

  4. Percentage of Participants With at Least a 1-Log, 2-Log, or 3-Log Reduction in HCV RNA [At Weeks 2, 4, 6, 8, 12, 16, 24, and 28]

    HCV RNA levels were obtained routinely during and after treatment. Reductions in HCV RNA viral load by 1-log, 2-log, or 3-log increments were determined relative to Baseline HCV RNA. Each increment represents a reduction greater than or equal to (≥) the specified log value, including results for which HCV RNA was below the limit of quantification (25 IU/mL). The percentage of participants with each log reduction in HCV RNA was calculated as [number of participants with log reduction divided by the number of participants analyzed] multiplied by 100.

  5. Percentage of Participants With Virological Relapse Following EOT Response [Up to 72 weeks (at 12 and 24 weeks after EOT)]

    Virological relapse was defined as a detectable post-treatment HCV RNA viral load following a previously undetectable EOT level (ie, virological response). The percentage of participants with virological relapse was calculated as [number of participants meeting the above criteria divided by the number of participants analyzed] multiplied by 100.

  6. Percentage of Participants With Virological Breakthrough Following On-Treatment Response [Up to 48 weeks (at Baseline; Weeks 2, 4, 6, 8, 12, 16, 24, 28, and 36; and EOT)]

    Virological breakthrough was defined as an HCV RNA viral load greater than (>) 1000 IU/mL following a previously undetectable level at any time during treatment (ie, virological response). Participants who ultimately achieved an EOT response were not considered for virological breakthrough. The percentage of participants with virological breakthrough was calculated as [number of participants meeting the above criteria divided by the number of participants analyzed] multiplied by 100.

  7. Percentage of Participants With Virological Rebound Following On-Treatment Decline in HCV RNA [Up to 48 weeks (at Baseline; Weeks 2, 4, 6, 8, 12, 16, 24, 28, and 36; and EOT)]

    Virological rebound was defined as an HCV RNA viral load >1000 IU/mL and a ≥1-log increase from nadir following a decline in HCV RNA from Baseline at any time during treatment (ie, on-treatment decline). Participants who ultimately achieved an EOT response were not considered for virological rebound. The percentage of participants with virological rebound was calculated as [number of participants meeting the above criteria divided by the number of participants analyzed] multiplied by 100.

  8. Percentage of Participants With Treatment Discontinued Based Upon Elevated (Week 12) or Detectable (Week 24) HCV RNA [At 12 and 24 weeks]

    Treatment was to be discontinued for participants who met prespecified criteria, termed the futility rule, after 12 or 24 weeks of treatment. Participants were discontinued from treatment for one of the following reasons: HCV RNA viral load ≥100 IU/mL (Week 12) or a detectable HCV RNA viral load (Week 24). HCV RNA viral load was measured using the Roche COBAS TaqMan 2.0 HCV Test, with a lower LOD of 10 to 15 IU/mL. The percentage of participants with treatment discontinued for each reason was calculated as [number of participants meeting one of the above criteria divided by the number of participants analyzed] multiplied by 100.

  9. Duration of Treatment With PEG-IFN, RBV, and Boceprevir [Up to 48 weeks (from Baseline until EOT)]

    The duration of treatment with each study drug was determined as the time from treatment start until the last dose of PEG-IFN, RBV, or boceprevir. Median duration of treatment was determined using the actual duration of treatment among individual participants and expressed in weeks.

  10. Percentage of Participants With a Dose Modification of PEG-IFN, RBV, or Boceprevir By Reason [Up to 48 weeks (from Baseline until EOT)]

    Dose modifications for each study drug included any dose reduction, treatment interruption, or premature withdrawal. Adverse event (AE)-related reasons were documented, as well as reasons related to insufficient efficacy ('Poor efficacy') or other safety-related reasons ('Safety/other'). The percentage of participants with a dose modification documented for each reason was calculated as [number of participants with dose modification divided by the number of participants analyzed] multiplied by 100.

  11. Percentage of Participants Receiving Target Administrations of PEG-IFN, RBV, and Boceprevir [Up to 48 weeks (from Baseline until EOT)]

    The frequency of missed treatments was examined using the number of administrations received as a percentage of target administrations for each study drug. The maximum number of possible administrations was considered in terms of once-weekly injections with PEG-IFN and in terms of treatment days with RBV and boceprevir. The percentage of target administrations each participant received was separated into ranges of <60%, 60 to <80%, 80 to <95%, and ≥95% for each study drug. The percentage of participants who received each range of target administrations was calculated as [number of participants in each range divided by the number of participants analyzed] multiplied by 100.

  12. Number of Participants With a Safety-Related Dose Modification [Up to 48 weeks (from Baseline until EOT)]

    Dose modifications for each study drug included any dose reduction, treatment interruption, or premature withdrawal. The percentage of participants with a safety-related dose modification (eg, modification due to adverse event or laboratory abnormality) of any study drug was calculated as [number of participants with dose modification divided by the number of participants analyzed] multiplied by 100.

  13. Time to Safety-Related Dose Modification [Up to 48 weeks (from Baseline until EOT)]

    Dose modifications for each study drug included any dose reduction, treatment interruption, or premature withdrawal. Median time to safety-related dose modification (eg, modification due to adverse event or laboratory abnormality) of any study drug was estimated using Kaplan-Meier and expressed in weeks.

  14. Percentage of Participants Using Concomitant Hematopoietic Stimulants During Treatment and Follow-Up [Up to 72 weeks (from Baseline until 24 weeks after EOT)]

    Use of concomitant hematopoietic stimulants (such as epoetin) during the 48-week treatment period and/or within 24 weeks of follow-up was documented. The percentage of participants using concomitant hematopoietic stimulants was calculated as [number of participants reporting concomitant use divided by the number of participants analyzed] multiplied by 100.

  15. Percentage of Participants With a Concomitant Disease Prior to or During the Study [Up to 76 weeks (from Screening until 24 weeks after EOT)]

    The prevalence of concomitant disease at any time from Screening through the end of follow-up was documented. The percentage of participants with a concomitant disease was calculated as [number of participants reporting or diagnosed with concomitant disease divided by the number of participants analyzed] multiplied by 100. Diseases documented for ≥5% of participants included hypertension, diabetes mellitus, hypothyroidism, and vitamin D deficiency as reported here.

  16. Percentage of Participants Using Concomitant Medications During Treatment and Follow-Up [Up to 72 weeks (from Baseline until 24 weeks after EOT)]

    Use of concomitant prescription or nonprescription medications during the 48-week treatment period and/or within 24 weeks of follow-up was documented. The percentage of participants using concomitant medications was calculated as [number of participants reporting concomitant use divided by the number of participants analyzed] multiplied by 100. Medication classes reported by >10% of participants included analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), antihistamines, corticosteroids, proton pump inhibitors, vitamins and minerals, and beta-adrenoceptor blocking agents as reported here.

Title Percentage of Participants With at Least a 1-Log, 2-Log, or 3-Log Reduction in HCV RNA
Description HCV RNA levels were obtained routinely during and after treatment. Reductions in HCV RNA viral load by 1-log, 2-log, or 3-log increments were determined relative to Baseline HCV RNA. Each increment represents a reduction greater than or equal to (≥) the specified log value, including results for which HCV RNA was below the limit of quantification (25 IU/mL). The percentage of participants with each log reduction in HCV RNA was calculated as [number of participants with log reduction divided by the number of participants analyzed] multiplied by 100.

Title Percentage of Participants With Virological Breakthrough Following On-Treatment Response
Description Virological breakthrough was defined as an HCV RNA viral load greater than (>) 1000 IU/mL following a previously undetectable level at any time during treatment (ie, virological response). Participants who ultimately achieved an EOT response were not considered for virological breakthrough. The percentage of participants with virological breakthrough was calculated as [number of participants meeting the above criteria divided by the number of participants analyzed] multiplied by 100.

Title Percentage of Participants With Treatment Discontinued Based Upon Elevated (Week 12) or Detectable (Week 24) HCV RNA
Description Treatment was to be discontinued for participants who met prespecified criteria, termed the futility rule, after 12 or 24 weeks of treatment. Participants were discontinued from treatment for one of the following reasons: HCV RNA viral load ≥100 IU/mL (Week 12) or a detectable HCV RNA viral load (Week 24). HCV RNA viral load was measured using the Roche COBAS TaqMan 2.0 HCV Test, with a lower LOD of 10 to 15 IU/mL. The percentage of participants with treatment discontinued for each reason was calculated as [number of participants meeting one of the above criteria divided by the number of participants analyzed] multiplied by 100.

12. Secondary Outcome
Title Percentage of Participants Receiving Target Administrations of PEG-IFN, RBV, and Boceprevir
Description The frequency of missed treatments was examined using the number of administrations received as a percentage of target administrations for each study drug. The maximum number of possible administrations was considered in terms of once-weekly injections with PEG-IFN and in terms of treatment days with RBV and boceprevir. The percentage of target administrations each participant received was separated into ranges of <60%, 60 to <80%, 80 to <95%, and ≥95% for each study drug. The percentage of participants who received each range of target administrations was calculated as [number of participants in each range divided by the number of participants analyzed] multiplied by 100.
Time Frame Up to 48 weeks (from Baseline until EOT)

Arm/Group Description Treatment-naive participants with CHC received treatment with PEG-IFN 180 mcg SC once weekly, weight-based RBV 1000 to 1200 mg PO daily in 2 divided doses, and boceprevir 800 mg PO every 7 to 9 hours. Participants received dual therapy with PEG-IFN and RBV from Week 0 to 4, and triple therapy was initiated at Week 4. Those with undetectable HCV RNA at Weeks 8 and 24 stopped treatment at Week 28. Those with detectable HCV RNA at Week 8 but undetectable HCV RNA at Week 24 continued triple therapy until Week 36 and received dual therapy from Week 36 to 48. Those with a <1-log decrease in HCV RNA at Week 4 continued triple therapy until Week 48, with optional dual therapy from Week 32 to 48 if triple therapy was not tolerated. Participants with compensated cirrhosis, regardless of response, received triple therapy until Week 48. Treatment-naive participants with CHC received treatment with PEG-IFN 180 mcg SC once weekly, weight-based RBV 1000 to 1200 mg PO daily in 2 divided doses, and boceprevir 800 mg PO every 7 to 9 hours. Participants received dual therapy with PEG-IFN and RBV from Week 0 to 4, and triple therapy was initiated at Week 4. Response-guided treatment was determined by assessments of virologic response at Weeks 4, 8, and 24. Participants with compensated cirrhosis (Cirrhotics), regardless of response, received triple therapy until Week 48. Treatment-naive participants with CHC received treatment with PEG-IFN 180 mcg SC once weekly, weight-based RBV 1000 to 1200 mg PO daily in 2 divided doses, and boceprevir 800 mg PO every 7 to 9 hours. Participants received dual therapy with PEG-IFN and RBV from Week 0 to 4, and triple therapy was initiated at Week 4. Response-guided treatment was determined by assessments of virologic response at Weeks 4, 8, and 24.
