简要总结
The primary objective is to assess the safety, efficacy and tolerability of the combination of PEG-Intron plus REBETOL in pediatric subjects with chronic hepatitis C. The secondary objective is to measure the multiple-dose pharmacokinetics of PEG-Intron and REBETOL in pediatric subjects with chronic hepatitis C.
详细描述
This global, multicenter, open-label Phase 3 study will evaluate the safety, efficacy and tolerability of PEG-Intron plus REBETOL in previously untreated pediatric subjects, ages 3 through 17 years, with chronic hepatitis C.
