NCT03903562

Brief Summary

This study will investigate the immunogenicity and safety of the 9vHPV vaccine in healthy Chinese females 9 to 45 years of age. The study consists of Stage I (Day 1 to Month 7) and Stage II (post Month 7 to Month 60). Stage II will report the long-term immunogenicity and safety in the 9-19 year-old age group only. The dual-primary hypotheses of Stage I are that 9vHPV vaccine induces non-inferior immune responses in females 9 to 19 years of age who are seronegative at Day 1 to the relevant HPV type compared to females 20 to 26 years of age who are seronegative at Day 1 to the relevant HPV type, as measured by anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 GMTs at 1 month post Dose 3, and 9vHPV vaccine induces non-inferior immune responses in females 27 to 45 years of age who are seronegative at Day 1 to the relevant HPV type compared to females 20 to 26 years of age who are seronegative at Day 1 to the relevant HPV type, as measured by the seroconversion percentages to each of HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58 at 1 month post Dose 3. (Each vaccine component will be analyzed separately.)

With regard to systemic corticosteroids, a participant will be excluded if she is currently receiving steroid therapy, has recently (defined as within 2 weeks of Day 1 vaccination) received such therapy, or has received 2 or more courses of corticosteroids (orally or parenterally) lasting at least 1 week in duration in the year prior to Day 1 vaccination. Participants using inhaled, nasal or topical corticosteroids are considered eligible for the study
