Detailed Description

This is a singel-center study (protocol 4-HPV-3002) in which women are planned to receive q-HPV vaccine. Study participation will last approximately 60 months and involves a total of nine or eleven scheduled visits. This study will also assess whether the immunogenicity of the q-HPV vaccine given 2-dose schedule in 9-14 year old girls is noninferior to that in young women, aged 20-26, receiving 3 doses, and 3 doses in 9-19 year old girls is noninferior to that in young women receiving 3 doses, while assessing the safety of this vaccine.

Interventions

  • Biological: 2-doses Group among 9-14 years
    • Subjects were planned to receive two doses of the study vaccine administered intramuscularly according to a 0, 6 month vaccination schedule.
  • Biological: 3-doses Group among 9-19 years
    • Subjects were planned to receive three doses of the study vaccine administered intramuscularly according to a 0, 2, 6 month vaccination schedule.
  • Biological: 3-doses Group among 20-26 years
    • Subjects were planned to receive three doses of the study vaccine administered intramuscularly according to a 0, 2, 6 month vaccination schedule.

Arms, Groups and Cohorts

  • Experimental: Experimental: 2-doses Group
    • Subjects aged 9-14 years, received 2 doses of q-HPV vaccine, which was administered intramuscularly in the deltoid muscle of the non-dominant arm according to a 0, 6-month schedule.
  • Experimental: Experimental: 3-doses Group
    • Subjects aged 9-19 years, received 3 doses of q-HPV vaccine, which was administered intramuscularly in the deltoid muscle of the non-dominant arm according to a 0, 2,6-month schedule.
  • Active Comparator: Acitve Group
    • Subjects aged 20-26 years, received 3 doses of q-HPV vaccine, which was administered intramuscularly in the deltoid muscle of the non-dominant arm according to a 0, 2,6-month schedule.

Clinical Trial Outcome Measures

Primary Measures

  • Primary immunogenicity outcome
    • Time Frame: At month 8
    • Number of subjects receiving the whole schedule vaccination with antibody responses as assessed by GMT and SCR, change from baseline among the seronegative vaccine recipients at Month 8

Secondary Measures

  • Secondary immunogenicity outcome
    • Time Frame: At month 12, 24, 36, 48 and 60
    • TNumber of subjects, aged 9 to 14, receiving the 2-doses scheduled vaccination with antibody responses as assessed by GMT and SCR, change from baseline among the seronegative vaccine recipients at Month 12, 24, 36, 48 and 60
  • Number of subjecs with AEs
    • Time Frame: Within 30 minutes (Days 0) after vaccination
    • Solicited general symptoms assessed were arthralgia, fatigue, gastrointestinal, headache, myalgia, rash, fever (= axillary temperature above 37.3°C or 37.5°C) and urticaria.
  • Numbers of subjects with solication of AEs
    • Time Frame: Within 8 days (Days 0-8) after vaccination
    • Solicited general symptoms assessed were arthralgia, fatigue, gastrointestinal, headache, myalgia, rash, fever (= axillary temperature above 37.3°C or 37.5°C) and urticaria.
  • Numbers of subjects with unsolicited AEs
    • Time Frame: Within days 0-30 after vaccination
    • An unsolicited adverse event is any adverse event (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms.
  • Number of subjects receiving the whole schedule vaccination with SAEs
    • Time Frame: Subjects receiving a 2-doses shceduled vaccination from Day o to Month 60; Subjects receiving a 3-doses shceduled vaccination from Day o to Month 12
    • SAEs assessed include medical occurrences that results in death, are life threatening, require hospitalization or prolongation of hospitalization, results in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subjects.
  • Number of subjects with pregnancy events
    • Time Frame: Subjects receiving a 2-doses shceduled vaccination from Day o to Month 60; Subjects receiving a 3-doses shceduled vaccination from Day o to Month 12
    • Outcomes of pregnancies were Live infant NO apparent congenital anomaly , Live infant, Elective termination NO ACA, Elective termination CA, Ectopic pregnancy, Spontaneous abortion NO ACA, Stillbirth NO ACA, Stillbirth CA, Lost to follow up and Pregnancy ongoing.
