简要总结

This study will evaluate the efficacy, immunogenicity and safety of 9-valent human papillomavirus (9vHPV; V503) vaccine in Chinese women 20 to 45 years of age. The primary hypotheses are: 9vHPV vaccine reduces the incidence of HPV 31-, 33-, 45-, 52-, and 58-related 12-month persistent infection at least 1 month post Dose 3, compared with quadrivalent HPV (qHPV) vaccine in women 20 to 45 years of age who are seronegative at Day 1 and polymerase chain reaction (PCR) negative Day 1 through Month 7 to the relevant HPV type; and 9vHPV vaccine induces non-inferior competitive luminex immunoassay (cLIA) geometric mean titers (GMTs) for each of HPV 6, 11, 16, and 18 one month post Dose 3, compared with qHPV vaccine in women 20 to 45 years of age who are seronegative at Day 1 and PCR negative Day 1 through Month 7 to the relevant HPV type.

详细描述

This study has two stages with the Stage I expected from Day 1 through Month 30, and the Stage II expected post-Month 30 to Month 90. The Stage I study is a case-driven study which aims to accrue at least 20 cases of HPV 31/33/45/52/58-related 12-month persistent infection and at least 39 cases of HPV 31/33/45/52/58-related 6-month persistent infection by completion of Month 30 visit. The Stage II study is a case-driven study which aims to accrue at least 12 cases of HPV 31/33/45/52/58-related cervical intraepithelial neoplasia grade 2 or 3 (CIN 2/3), cervical adenocarcinoma in situ (AIS), and cervical cancer observed in both Stage I and Stage II, by completion of Month 90 visit.

After completion of Stage II, participants in the qHPV vaccine group will be offered a 3-dose regimen of V503 in the Extension Stage. Participants in the V503 group who did not complete the 3-dose regimen in Stage I will also be eligible to receive any remaining V503 doses to complete the regimen.

结局指标

主要结局

Stage I: Combined Incidence of HPV 31-, 33-, 45-, 52-, and 58-related 12-month Persistent Infection

时间窗: 1 month post vaccination 3 (Month 7) up to Month 30

A 12-month persistent infection This endpoint is defined to have occurred if a participant who is positive for the same HPV type by the HPV PCR assay in the LVPP/EEC swabs, biopsy, ECC or definitive therapy samples obtained in 3 or more consecutive visits over a period of at least 12 months. Incidence is defined as the number of cases of persistent infection per 10,000 person-years of follow-up in a treatment arm.

Stage I: Percentage of Participants Who Report at Least 1 Solicited Injection-site Adverse Event

时间窗: up to 8 days post any vaccination

An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study vaccine. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study vaccine or protocol-specified procedure is also an AE. AEs such as redness, swelling, and pain/tenderness/soreness at the injection site are recorded.

Stage I: Geometric Mean Titers to HPV Types 6, 11, 16, and 18 Antibodies

时间窗: 1-month post vaccination 3 (Month 7)

Serum antibodies to HPV types 6/11/16/18 are measured with a Competitive Luminex Immunoassay (cLIA). Titers are reported in milli Merck Units/mL.

Stage I: Percentage of Participants Who Report at Least 1 Solicited Systemic Adverse Event

时间窗: up to 30 days post any vaccination

An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study vaccine. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study vaccine or protocol-specified procedure is also an AE. Systemic AEs are those not categorized as injection-site AEs.

Stage I: Percentage of Participants Who Experience at Least 1 Serious Adverse Event (SAE)

时间窗: Day 1 up to approximately Month 30

An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study vaccine. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study vaccine or protocol-specified procedure is also an AE. An SAE is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, or is another important medical event.

Stage II: Combined Incidence of HPV 31-, 33-, 45-, 52-, and 58-related CIN 2/3, AIS, and cervical cancer

时间窗: Month 7 up to Month 90

This endpoint is defined to have occurred if on a single cervical biopsy, ECC, LEEP or Conization (cold knife/laser) specimen, there is: (a) a HPV Pathology Panel consensus diagnosis of CIN (grade 2 or 3), AIS, or cervical cancer; AND (b) detection of at least 1 of HPV types 31, 33, 45, 52 or 58 by Thinsection PCR in an adjacent section from the same tissue block. Disease incidence is defined as the number cases per 10,000 person-years of follow-up in a treatment arm.

Stages I/II: Percentage of Participants Who Experience at Least 1 Serious Adverse Event (SAE)

时间窗: Day 1 up to approximately Month 90

An AE is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study vaccine. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or a protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study vaccine or protocol-specified procedure is also an AE. An SAE is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, or is another important medical event.
