Brief summary

A study to test the safety and effectiveness of Quadrivalent HPV (types 6, 11, 16, 18) L1 VLP vaccine against combined incidence of HPV 6/11/16/18-related persistent infection and vaccine type-specific genital disease among Chinese females between the ages of 20 and 45.

Detailed description

The Base Study V501-041 duration was 30 months. The study was extended to further evaluate the efficacy of Quadrivalent HPV (Type 6, 11, 16, 18) L1 VLP (qHPV) vaccine against Cervical Intraepithelial Neoplasia Grade 2 (CIN 2), CIN 3, Adenocarcinoma In Situ (AIS), and/or cervical cancer. The efficacy was followed through the Month 78 visit, and the close-out visit was conducted at approximately Month 90 with only safety data collected

Interventions

Quadrivalent Human Papillomavirus (Types 6, 11, 16, 18) Recombinant Vaccine injection at Day 1, Month 2, and Month 6.

BIOLOGICALComparator: placebo (unspecified)

Aluminum-containing Vaccine placebo injection at Day 1, Month 2, and Month 6.

Base Study: Percentage of Participants Discontinued From Study Vaccination Due to an Adverse EventUp to 6 monthsAn AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the sponsor's product, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the sponsor's product, is also an AE.
Entire Study: Percentage of Participants With One or More Vaccine-related Serious Adverse EventsUp to approximately 90 monthsA serious adverse event (SAE) is an AE that results in death, is life threatening, results in persistent or significant disability or incapacity, results in or prolongs a hospitalization, is a congenital anomaly or birth defect, is an overdose or, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention. Related SAEs were those deemed possibly, probably, or definitely related to study vaccine or a study procedure.
