Официальное название

Evaluating the Immunogenicity and Safety of Quadrivalent Human Papillomavirus Recombinant Vaccine (Type 6, 11, 16, 18) in Healthy Chinese Female Subjects Aged 9 to 26 Years: A Phase 3, Open-label, Non-randomized Clinical Trial

Обзор

This phase 3 study will evaluate the immunogenicity and safety of Quadrivalent HPV recombinant vaccine in Chinese females aged 9 to 26 years

Подробное описание

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.

Вмешательства

• Биопрепарат 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.
• Биопрепарат 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.
• Биопрепарат 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.
