Detaljeret beskrivelse

This is a randomized (study drug assigned by chance), open-label (all persons know the study drug assignment) multicenter study to evaluate the effectiveness of telaprevir administered orally as 1125 milligram (mg) twice daily versus 750mg every 8 hours in combination with Peg-IFN-alfa-2a, administered via intramuscular injection once a week, and ribavirin, administered as an oral tablet twice a day, in treatment-naïve study participants with chronic hepatitis C virus (HCV) genotype 1 infection.

Telaprevir will be given orally (by mouth) from Day 1 through Week 12 as 3 tablets (1125mg) twice daily or 2 tablets (750mg) every 8 hours. Peg-IFN-alfa-2a will be administered once a week as an injection under the skin (180 microgram/week) from Day 1 through Week 24 or 48 (based on the patient's treatment response on week 4). Ribavirin is administered orally (by mouth) twice daily from Day 1 through Week 24 or 48 (based on the participant's treatment response on week 4) as 1,000-1,200 mg per day. After the end of treatment (Week 24, Week 48, or at early discontinuation of all study drugs), participants with undetectable HCV RNA at end of treatment will be required to attend follow-up visits until Week 72 safety/tolerability assessments will be performed throughout the treatment period and during the follow-up period.

Tidsramme
Percentage of Participants With Sustained Virologic Response 24 Weeks After the Last Planned Dose of Study Drugs (SVR24 Planned)
Tidsramme: End of trial, 24 weeks after last planned dose
The table below shows the percentage of participants achieving SVR 24 weeks after the last planned dose of study medication. SVR was defined as having Hepatitis C Virus (HCV) ribonucleic acid (RNA) levels less than 25 international units/milliliter (IU/mL). The response for T12(b.i.d)/PR group is higher than that after 12 weeks because HCV RNA data for two participants were missing for SVR assessment at that time. Consequently, by definition of SVR12, they were counted as not having achieved SVR12.
End of trial, 24 weeks after last planned dose
Percentage of Participants With Sustained Virologic Response 72 Weeks After the Start of Study Medication (SVR72 Planned)
Tidsramme: End of trial, 72 weeks after the start of study medication
The table below shows the percentage of participants achieving SVR 72 weeks after the start of study medication (SVR72 planned). SVR was defined as having plasma Hepatitis C Virus (HCV) ribonucleic acid (RNA) levels less than 25 IU/mL, target not detected, at end of treatment and up to 72 weeks after start of study medication (i.e., no confirmed detectable HCV RNA in between).
End of trial, 72 weeks after the start of study medication
Percentage of Participants Achieving Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Values of Less Than 25 IU/ml, Target Not Detected, at Different Time Points.
Tidsramme: Baseline, Week 4 and Week 4+12.
The table below shows the percentage of participants with undetectable hepatitis C virus (HCV) ribonucleic acid (RNA) levels, which means less than 25 IU/ml, target not detected, at different time points during the study.
Baseline, Week 4 and Week 4+12.
Percentage of Participants With On-treatment Virologic Failure Which Required Them to Permanently Discontinue All Study Drugs
Tidsramme: Week 4, 12, 24, 32, 40
The table below shows the percentage of participants who met a stopping rule, defined as having a hepatitis C virus (HCV) ribonucleic acid (RNA) value at Week 4 >1000 IU/mL and at Weeks 12, 24, 32 and 40 ≥25 IU/mL.
Week 4, 12, 24, 32, 40
Percentage of Participants Who Relapsed During Follow-up Period
Tidsramme: During Follow-Up (24 weeks after the last dose of study drug)
The table below shows the percentage of participants who relapsed (ie, those having confirmed detectable hepatitis C virus [HCV] ribonucleic acid [RNA] during the 12-week follow-up period after previous HCV RNA <25 IU/mL, target not detected, at end of treatment).
During Follow-Up (24 weeks after the last dose of study drug)
Percentage of Participants of Each IL28B Genotype Achieving Sustained Virologic Response 12 Weeks After the Last Planned Dose of Study Medication (SVR12 Planned)
