Outcome Measures

Primary Outcomes (3)

  • Non-inferiority of anti-HPV 16 and 18 seroconversion rates and geometric mean concentrations at Months 7 (type specific neutralizing antibody) in the PPS-I set

    Detect the level of anti-HPV 16 and 18 specific neutralizing antibodies at one month after the third dose to determine whether nine-valent HPV vaccine is non-inferior to the control bivalent HPV vaccine

    Specific neutralizing antibodies at 7 months after first dose

  • Persistent infection of HPV31, 33, 45, 52 and 58 (over 12 months) (Combined analysis of the 5 types) in the mITT-PI set

    To evaluate the efficacy of the nine-valent vaccine against this outcome compared with the control vaccine

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Incidence of CIN2 + and/or VIN2 + and/or VaIN2 + lesions related to HPV 31, 33, 45, 52 or 58 (Combined analysis of the 5 types) in the mITT-E when the first two endpoints are satisfied

    To evaluate the efficacy of the nine-valent vaccine against this outcome compared with the control vaccine

    Cumulative incidence of this endpoint events in 78 months after the first dose

Secondary Outcomes (16)

  • Efficacy1: Incidence of CIN2 + and/or VIN2 + and/or VaIN2 + lesions related to HPV 31, 33, 45, 52 or 58(Combined analysis of the 5 types) and genital warts related to HPV 6, 11 (Combined analysis of each type)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Efficacy2: Incidence of CIN1 + and/or VIN1 + and/or VaIN1 + lesions related to HPV 31, 33, 45, 52 or 58(Combined analysis of the 5 types) and genital warts related to HPV 6, 11 (Combined analysis of each type)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Efficacy3: Incidence of Persistent infection of HPV31, 33, 45, 52 and 58 (transient infection and over 6 months) (Combined analysis of the 5 types)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Efficacy4: Incidence of CIN1 + and/or VIN1 + and/or VaIN1 + lesions related to HPV 31, 33, 45, 52 or 58(Combined analysis of the 5 types)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Efficacy5: Incidence of Persistent infection of HPV31, 33, 45, 52 and 58 (over 6 months) and/or incidence of CIN1 + and/or VIN1 + and/or VaIN1 + lesions related to HPV 31, 33, 45, 52 or 58(Combined analysis of the 5 types)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • +11 more secondary outcomes

Other Outcomes (3)

  • Incidence of CIN2 + and/or VIN2 + and/or VaIN2 + lesions related to HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 or 68 (Combined analysis of the high risk types)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Incidence of CIN1 + and/or VIN1 + and/or VaIN1 + lesions related to HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 or 68 (Combined analysis of the high risk types)

    Cumulative incidence of this endpoint events in 78 months after the first dose

  • Incidence of Persistent infection of HPV35, 39,51,56,59 and 68 (total infection and over 6 months and over 12 months) (Independent analysis of each type)

    Cumulative incidence of this endpoint events in 78 months after the first dose
