研究概览
简要总结
This study is designed to evaluate the immunogenicity, safety, and tolerability of Gardasil® (quadrivalent human papillomavirus [qHPV] vaccine, V501) in Chinese girls aged 9-19 years and young women aged 20-26 years. The primary hypothesis of the study states that at 1 month postdose 3, a 3-dose regimen of V501 induces non-inferior geometric mean titers (GMTs) for serum anti-HPV 6, anti-HPV 11, anti-HPV 16, anti-HPV 18 in girls aged 9-19 years compared to young women aged 20-26 years.
详细描述
The study consists of a Base Stage wherein Chinese girls aged 9-19 years and young women aged 20-26 years receive a 3-dose regimen of V501 and are followed up to 1 month postdose 3 (Month 7). Participants aged 9-19 years who received 3 doses of V501 in the Base Stage will be eligible to participate in the Extension Stage and will be followed up to Month 60. No study vaccine will be administered during the Extension Stage.
