| NCT01544920 | Safety and Efficacy of Boceprevir/Peginterferon Alfa-2a/Ribavirin in Interleukin-28B CC Allele-Positive Chronic Hepatitis C Virus (HCV) Genotype 1 Participants (P07755) | PHASE3 | COMPLETED | 737 | — | — | May 30, 2012 | May 19, 2015 | Sep 11, 2018 | - | — |
SVR24 rates were determined for all participants in Arm 1 and Arm 2. HCV RNA viral load was determined using the Roche COBAS® AmpliPrep/COBAS® TaqMan HCV Test v1.0, which has a lower limit of quantification of 43 IU/mL.
| Arm | Type | Description |
|---|---|---|
| Arm 1: peg-IFN + RBV | ACTIVE_COMPARATOR | Participants received an initial 4 week lead-in of peg-IFN + RBV. Following HCV RNA analysis at Week 4, participants with undetectable HCV RNA received open label peg-IFN + RBV for an additional 18 weeks (total of 24 weeks of peg-IFN/RBV therapy) \[Arm 1a\]. Participants with detectable HCV RNA at Week 4 had BOC added to the peg-IFN + RBV regimen at Week 6 and then followed the Response Guided Therapy (RGT) regimen for BOC + peg-IFN + RBV \[Arm 1b\]. |
| Arm 2: BOC + peg-IFN + RBV | EXPERIMENTAL | Participants received an initial 4-week lead-in of peg-IFN + RBV. Following HCV RNA analysis at Week 4, all participants had BOC added to the peg-IFN + RBV regimen at Week 6 regardless of HCV RNA levels. Participants who had undetectable HCV RNA at Week 4 continued on the BOC + peg-IFN + RBV regimen for an additional 20 weeks (total of 24 weeks of BOC + peg-IFN + RBV therapy) \[Arm 2a\]. Participants with detectable HCV RNA at Week 4 followed the RGT regimen for BOC + peg-IFN + RBV \[Arm 2b\]. |
