  • Area Under the Curve From Baseline to Week 60 (AUC60) and Week 72 (AUC72) for the Fatigue Severity Scale (FSS) Total Scores [ Time Frame: Baseline to Week 60 and Week 72 ] [ Designated as safety issue: No ]
    Study participants completed FSS questionnaires during study visits before treatment began and throughout treatment and follow-up to rate the severity and impact of fatigue they experienced in the preceding 2 weeks on their daily lives. FSS total scores are the average of nine questions with a range from 1 [no fatigue] to 7 [worst possible fatigue]. An area under the curve (AUC) analysis compared the overall severity of fatigue in each treatment group from baseline to Week 72. The null hypothesis was that there would be no difference between the treatment arms in the amount of fatigue participants experienced throughout the study resulting in equal AUC from baseline to Week 72 (AUC72) for FSS total scores. The Table below shows the lease squares (LS) mean estimates of AUC at Week 72 (as well as at Week 60) and the statistical comparison between treatment groups.

  • Area Under the Curve From Baseline to Week 60 (AUC60) and Week 72 (AUC72) for Impairment in Overall Work Productivity Scores Due to Hepatitis C Virus (HCV) Infection and Its Treatment [ Time Frame: Baseline to Week 60 and Week 72 ] [ Designated as safety issue: No ]
    Impairment in overall work productivity was measured using the Work Productivity and Activity Impairment (WPAI): Hepatitis C questionnaire completed by participants during study visits throughout the study. WPAI Overall Productivity Scores ranged from 0% to 100% (higher WPAI scores indicated greater impairment in productivity). An area under the curve (AUC) analysis compared the overall WPAI Overall Work Productivity Scores in each treatment group from Baseline to Week 72. The null hypothesis was that there would be no difference between the treatment arms in the WPAI Overall Work Productivity Scores from Baseline to Week 72. The Table below shows the lease squares (LS) mean estimates of AUC at Week 72 (as well as at Week 60) in WPAI Work Productivity Scores and the statistical comparison between treatment groups.

    Impairment in daily activity was measured using the Work Productivity and Activity Impairment (WPAI): Hepatitis C questionnaire, Question 6. Scores ranged from 0 (no effect on activities) to 10 (completely prevented me from doing my daily activities). An area under the curve (AUC) analysis compared the impairment in daily activity scores in each treatment group from Baseline to Week 72. The null hypothesis was that there would be no difference between the treatment arms in impairment in daily activity scores from Baseline to Week 72. The Table below shows the lease squares (LS) mean estimates of AUC at Week 72 (as well as at Week 60) in the impairment in daily activity scores and the statistical comparison between treatment groups.

  • Area Under the Curve From Baseline to Week 60 (AUC60) and Week 72 (AUC72) in Work Productivity and Activity (WPAI) Absenteeism Scores Due to Hepatitis C Virus (HCV) Infection and Its Treatment [ Time Frame: Baseline to Week 60 and Week 72 ] [ Designated as safety issue: No ]
    Time missed from work in hours because of HCV infection or its treatment was assessed by measuring the change from baseline in the Work Productivity and Activity Impairment (WPAI): Hepatitis C questionnaire Absenteeism score (time missed from work, question #2). The number of hours missed from work because of HCV was divided by the total number of hours supposed to work, and expressed as a percentage. An area under the curve (AUC) analysis compared the WPAI absenteeism scores in each treatment group from Baseline to Week 72. The null hypothesis was that there would be no difference between the treatment arms WPAI absenteeism scores from Baseline to Week 72. The Table below shows the lease squares (LS) mean estimates of AUC at Week 72 (as well as at Week 60) in WPAI absenteeism scores and the statistical comparison between treatment groups.

Detailed Description:

This is a randomized, double-blind (neither physician nor participants know the name of the assigned drug), placebo-controlled study of TMC435 in participants who are infected with genotype 1 hepatitis C virus (HCV), who have never received treatment for HCV infection before. Participants in this study will also receive two other drugs for their HCV infection called peginterferon alpha-2a (PegIFN alpha-2a) and ribavirin (RBV). The purpose of the study is to investigate if TMC435 is superior to placebo in reducing plasma levels of HCV ribonucleic acid (RNA) to an undetectable level 12 weeks after the end of treatment. For the first 12 weeks, participants will take either TMC435 or placebo, plus PegIFNα-2a and RBV. For the next 12 weeks, participants will take PegIFN alpha-2a and RBV only. After that, some participants will continue to take PegIFN alpha-2a and RBV for up to 24 additional weeks and some will stop taking PegIFN alpha-2a and RBV depending on response-guided treatment criteria. The study doctor will inform each participant about how to take their study medication and when they should stop taking it. After a participant stops taking study medication, they will continue to come to the doctor's office for study visits until a total of 72 weeks after they enroll in the study. The total duration of the study is 78 weeks (including screening). Participants will be monitored for safety throughout the study.
