A Study to Evaluate the Immunogenicity, Safety and Tolerability of Quadrivalent Human Papillomavirus Vaccine (V501) in Chinese Girls Aged 9-19 Years and Young Women Aged 20-26 Years (V501-213)
November 9, 2023 updated by: Merck Sharp & Dohme LLC
A Phase 3 Open-Label Clinical Trial to Study the Immunogenicity, Safety and Tolerability of Recombinant Human Papillomavirus Quadrivalent (Types 6, 11, 16, 18) Vaccine (V501) in Chinese Girls Aged 9-19 Years and Young Women Aged 20-26 Years
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.

Maximum Axillary Temperature: Merck Sharp & Dohme (MSD) Criteria: Base Stage
Time Frame: Up to 5 days after any vaccination

In the global studies, fever is defined as an oral temperature of ≥37.8°C or 100.0°F, which is equivalent to axillary temperature of ≥37.2°C, while the definition of fever is axillary temperature of ≥37.1°C in Chinese criteria.
To be compliant to Chinese criteria, axillary temperatures of ≥37.1°C was considered as a fever in this study.
Body temperature readings assessed orally were converted to the axillary equivalent.
The percentage of participants with a maximum axillary or converted axillary temperature was summarized by temperature range.
