Recruitment details

Screening details

368 participants enrolled on study. 36 cirrhotic participants received open-label (OL) grazoprevir + peginterferon (Peg-IFN) + ribavirin (RBV), and 332 non-cirrhotic participants were randomized to receive 100, 200, 400, or 800 mg grazoprevir + Peg-IFN + RBV. 43 in the 400 mg group and 36 in the 800 mg group were down-dosed to 100 mg grazoprevir.

End point description

Blood was drawn from each participant to assess Hepatitis C Virus ribonucleic acid (HCV RNA) plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 at various time points prior to, during, and after dosing. The Roche COBAS Taqman HCV Test, v2.0 assay (High Pure System) had a lower limit of quantification of 25 IU/mL and a limit of detection of 9.3 IU/mL (in plasma). cEVR was defined as undetectable HCV RNA (target not detected [TND]) at Week 12. 95% confidence intervals provided based on the Clopper-Pearson method. A Missing = Failure approach was used for missing data. Results for participants who received grazoprevir 400 or 800 mg and were then down-dosed to receive grazoprevir 100 mg are reported separately from participants who completed the 400 mg and 800 mg regimens.

End point description

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR’s product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR’s product, was also an AE. Participants who received grazoprevir 400 or 800 mg and were then down-dosed to receive grazoprevir 100 mg are reported separately from participants who completed the 400 mg and 800 mg regimens.

Grazoprevir 100 mg vs. Boceprevir 800 mg

Statistical analysis description

The percentage of participants with at least one AE was evaluated for each grazoprevir arm in combination with Peg-IFN and RBV relative to the control boceprevir regimen. 95% confidence intervals for between-treatment differences in the percentage of participants with events were calculated using the Miettinen and Nurminen method.

Grazoprevir 100 mg vs. Boceprevir 800 mg

Statistical analysis description

The percentage of participants that discontinued study medication due to an AE was evaluated for each grazoprevir arm in combination with Peg-IFN and RBV relative to the control boceprevir regimen. 95% confidence intervals for between-treatment differences in the percentage of participants with events were calculated using the Miettinen and Nurminen method.

Median Time to First Achievement of Undetectable HCV RNA During Treatment

End point description

Blood was drawn from each participant to assess Hepatitis C Virus ribonucleic acid (HCV RNA) plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 at various time points prior to, during, and after dosing. Undetectable HCV RNA (target not detected [TND]) was defined as below the 9.3 IU/ml limit of detection. Kaplan Meier summary statistics were calculated for each treatment arm. Results for participants who received grazoprevir 400 or 800 mg and were then down-dosed to receive grazoprevir 100 mg are reported separately from participants who completed the 400 mg and 800 mg regimens. Participants in the FAS not achieving TND were censored.

End point description

Blood was drawn from each participant to assess Hepatitis C Virus ribonucleic acid (HCV RNA) plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 at various time points prior to, during, and after dosing. The Roche COBAS Taqman HCV Test, v2.0 assay (High Pure System) had a lower limit of quantification of 25 IU/mL and a limit of detection of 9.3 IU/mL (in plasma). RVR was defined as undetectable (TND) HCV RNA at Week 4 of study therapy. 95% confidence intervals provided based on the Clopper-Pearson method.

Were there any global substantial amendments to the protocol? Yes

08 Jul 2011

Protocol amendment 1 (AM1) added the response-guided therapy regimen for the boceprevir control arm, revised the criteria for virologic failure for all arms, included changes to the prohibited concomitant medications, and removed Area under the concentration-time curve as a pharmacokinetic (PK) endpoint.

29 Sep 2011

AM2 added a semen analysis substudy to the study flow chart, added exclusion criteria for the semen analysis substudy, changed the missing data approach, and updated guidance for missed doses of grazoprevir.

26 Jan 2012

AM3 revised protocol text, study diagram, flow chart, study objectives, eligibility criteria, and statistical analysis text to include a prior treatment failure and compensated cirrhotic patient cohort. AM3 also added a second planned interim analysis and modified AE and blood chemistry analysis.

10 Apr 2012

AM4 revised text throughout the protocol to remove the prior treatment failure and compensated cirrhotic patient cohort and added text throughout the protocol describing results and actions related to the first interim analysis including the down-dosing of patients in the 400 mg and 800 mg grazoprevir arms to 100 mg

04 Jan 2013

AM5 added a cohort to study 100 mg grazoprevir in combination with PEG-IFN and RBV in treatment-naïve cirrhotic patients and revised eligibility criteria for this new cohort accordingly.

29 Mar 2013

AM6 added a dosing duration modification for the cirrhotic cohort assigned to the 24-week treatment duration, and made revisions to the study flow chart, eligibility criteria, PK Analysis section, and HCV RNA analysis section in relation to the cirrhotic cohort.

Were there any global interruptions to the trial? No
