Safety and Immunogenicity of Extended 2-dose Regimens of 9vHPV Vaccine
EU CTIS ID: 2022-500256-37-00
What this study is testing
1. In a population who are seronegative to the relevant HPV type at Day 1, to demonstrate that administration of a 2-dose regimen of 9vHPV vaccine in boys and girls 9 to 14 years of age induces noninferior cLIA GMTs of antibodies to each of the 9vHPV vaccine types compared with young women 16 to 26 years of age receiving a 3-dose regimen of the same vaccine at Day 1, Month 2, and Month 6. 2. In 10- to 15-year-old boys and girls who received a single dose of 9vHPV vaccine at least 1 year prior to enrollment, to characterize the immune response to a second dose of 9vHPV vaccine (as measured by cLIA GMTs of antibodies to each of the 9vHPV vaccine types) at 4 weeks post dose 2 taking into account the time interval between administration of doses 1 and 2 (Cohort 0). 3. To evaluate the safety of administering the 9vHPV vaccine based on the dosing regimens investigated in this study. Four 2-dose cohorts (Cohorts 1-4) are compared to the 3-dose cohort (Cohort 5) in this objective. Cohort 1: 9-14-year-olds receiving 2 doses 12 months apart; Cohort 2: 9-13-year-olds receiving 2 doses 24 months apart; Cohort 3: 9-12-year-olds receiving 2 doses 36 months apart; Cohort 4: 9-10-year-olds receiving 2 doses 60 months apart; and Cohort 5: 16-26-year-old women receiving 3 doses.
