Current Primary Outcome Measures ICMJE |
Sustained Virologic Response (SVR) Rate [ Time Frame: Assessed at the end of a 24-week post-treatment follow-up ] [ Designated as safety issue: No ] SVR rate is the percentage of participants with undetectable hepatitis C virus ribonucleic acid (HCV-RNA) at the end of the 24-week post-treatment follow-up. |
Original Primary Outcome Measures ICMJE |
Proportion of subjects with a sustained virologic response (SVR) at 24 weeks post-treatment. Co-primary treatment comparisons include: Arm 1 (PegIntron 1.5/R) vs Arm 2 (PegIntron 1.0/R), Arm 1 vs Arm 3 (PEGASYS/COPEGUS). [ Time Frame: 48-week treatment; 24-week follow-up ] [ Designated as safety issue: No ] |

Brief Title ICMJE | Peginterferon Dose Evaluations for Previously Untreated Subjects With Chronic Hepatitis C Infected With Genotype 1 (Study P03471AM1)(COMPLETED) |
Official Title ICMJE | Comparison of PEG-Intron 1.5µg/kg/wk Plus REBETOL vs PEG-Intron 1µg/kg/wk Plus REBETOL vs PEGASYS 180µg/wk Plus COPEGUS in Previously Untreated Adult Subjects With Chronic Hepatitis C Infected With Genotype 1 |
Brief Summary | The objective is to compare the safety and efficacy of the following three treatment regimens in previously untreated adult subjects with chronic hepatitis C infected with Genotype 1: (1) PegIntron 1.5 µg/kg/wk in combination with weight based REBETOL (800-1400 mg/day); (2) PegIntron 1µg/kg/wk in combination with weight based REBETOL (800-1400 mg/day); and (3) PEGASYS 180 µg/wk plus COPEGUS 1000-1200 mg/day. |
Detailed Description | PegIntron Dose will be administered once weekly subcutaneously on the same day of the week: Screening 2 Weight 40-50 kg Volume to Inject (mL) 0.22; Screening 2 Weight 51-60 kg Volume to Inject (mL) 0.28; Screening 2 Weight 61-75 kg Volume to Inject (mL) 0.33; Screening 2 Weight 76-85 kg Volume to Inject (mL) 0.41; Screening 2 Weight 86-104 kg Volume to Inject (mL) 0.48; Screening 2 Weight 105-125 kg Volume to Inject (mL) 0.58 from two vials REBETOL Dosage (for Use With PegIntron): Screening 2 Weight 40-65 kg Daily Dose 800 mg; Screening 2 Weight >65-85 kg Daily Dose 1000 mg; Screening 2 Weight >85-105 kg Daily Dose 1200 mg; Screening 2 Weight >105-125 kg Daily Dose 1400 mg The PEGASYS dose of 1 mL (180 µg) will be administered once weekly subcutaneously on the same day of the week COPEGUS Dosage (for Use With PEGASYS): Screening 2 Weight <75 kg Daily Dose 1000 mg; Screening 2 Weight > or = 75 kg Daily Dose 1200mg NOTE: Double Blind for PegIntron; Open Label for REBETOL, PEGASYS and COPEGUS NOTE: REBETOL is the Schering-Plough brand name for ribavirin. COPEGUS is the Hoffman-La Roche brand name for ribavirin. |
