A Phase 3 clinical trial evaluating V501 for Prevention of HPV Types 16- and 18-related Cervical Cancer, Cervical Intraepithelial Neoplasia (CIN) 1/2/3, and Cervical Adenocarcinoma in Situ. Completed, enrolled 766 participants across 1 site.

Detailed Summary

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.
