Official title

Overview

A total of 13500 Chinese women aged 18-45 years old were divided into three age groups: 18-26 years old, 27-35 years old, and 35-45 years old. The experimental group and the placebo group were randomly assigned in a ratio of 1:1. All subjects enrolled in the upper arm deltoid muscle were injected with 3 doses of test vaccine or placebo according to the 0, 2, and 6 months immunization program.

Interventions

• Biological 11-valent recombinant human papilloma virus vaccine (Hansenula polymorpha)
  According to the 0, 2, and 6 months immunization program, intramuscular injection of the upper arm deltoid muscle, 3 doses of the experiment vaccine
• Biological placebo
  According to the 0, 2, and 6 months immunization program, intramuscular injection of the upper arm deltoid muscle, 3 doses of the placebo

Primary outcome measures

• Person-years incidence of CIN2+ associated with HPV6/11/16/18. [Time frame: 1 month after 3 doses of vaccine]
• Person-years incidence of CIN2+ associated with HPV31/33/45/52/58/59/68 [Time frame: 1 month after 3 doses of vaccine]

Secondary outcome measures (12)

• Person-years incidence of PI12 and PI6 associated with HPV6/11/16/18 types. [Time frame: 1 month after 3 doses of vaccine]
• Person-years incidence of PI12 and PI6 associated with HPV31/33/45/52/58 [Time frame: 1 month after 3 doses of vaccine]
• Person-years incidence of HPV6/11/16/18/31/33/45/52/58/59/68 types associated with CIN2+, CIN1+, PI12 and PI6 [Time frame: 1 month after 3 doses of vaccine]
• Person-years incidence of HPV6/11/16/18/31/33/45/52/58/59/68-associated anogenital and vaginal lesions (including: genital warts, VIN1+, VaIN1+, and AIN1+). [Time frame: 1 month after 3 doses of vaccine]
• Person-years incidence of CIN2+, PI12 and PI6 associated with HPV6/11/16/18 [Time frame: After at least 1 dose of vaccine]
• Person-years incidence of CIN2+, PI12 and PI6 associated with HPV31/33/45/52/58/59/68 [Time frame: After at least 1 dose of vaccine]
• Person-years incidence of CIN2+, CIN1+, PI12 and PI6 associated with HPV6/11/16/18/31/33/45/52/58/59/68 types. [Time frame: After at least 1 dose of vaccine]
• Person-years incidence of HPV6/11/16/18/31/33/45/52/58/59/68-associated anogenital and vaginal lesions (including: genital warts, VIN1+, VaIN1+, and AIN1+). [Time frame: After at least 1 dose of vaccine]
• AE incidence and severity distribution [Time frame: The first dose of vaccination to within 1 month after the full vaccination]
• AE incidence and severity distribution [Time frame: 0-30 days after each dose vaccination (including 30 minutes, 0-7 days, 8-30 days)]
• SAE incidence [Time frame: During the study，an average of 6 year]
• Number of pregnant [Time frame: The first dose of vaccination to within 6 months after the full vaccination]
