Trial Outcomes & Findings for A Study of V503 (A Multivalent Human Papillomavirus [HPV] L1 Virus-Like Particle [VLP] Vaccine) in Preadolescents and Adolescents (V503-002) (NCT NCT00943722)

NCT ID: NCT00943722

Last Updated: 2022-10-03

Results Overview

Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using a competitive luminex immunoassay (cLIA). Titers were reported in milli Merck Units/mL.

Participant Flow

The base study was a 12-month study that collected immunogenicity data through Month 7 and safety data through Month 12.

Extension study 1 (EXT1) collected data to Month 36. Extension study 2 (EXT2) collected long-term data through \~Month 126. No study vaccine was administered. Per protocol, participants enrolled in the 16- to 26-year-old arm in the base study were not included in the extension study. Per protocol, the extension study included data from 9- to 15-year-old females regardless of lot administered (arm: "Extension Study: 9- to 15- Year Old Females").

PRIMARY outcome

Timeframe: 4 weeks post-vaccination 3 (Month 7)

Population: 9-15-year-old females and 16-26-year-old females who received 3 vaccinations from Lot 1 and met following criteria for at least 1 of the 9 HPV types: no general protocol violations, received all 3 vaccinations within acceptable day ranges, seronegative at Day 1 for HPV type(s), and had a Month 7 serum sample collected within an acceptable day range.

Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using a competitive luminex immunoassay (cLIA). Titers were reported in milli Merck Units/mL.

PRIMARY outcome

Timeframe: Up to 5 days after any vaccination

Population: All participants who received at least one dose of 9vHPV vaccine and had available follow-up data. Per protocol, this outcome measure included data from 9- to 15-year-old females regardless of lot administered.

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine was also an AE. AEs such as redness, swelling, and pain/tenderness/soreness at the injection site were recorded.

SECONDARY outcome

Timeframe: Up to ~Month 126

Population: The per-protocol effectiveness population, which included participants who were seronegative (by cLIA) to the relevant HPV type(s) at Day 1 (seronegative to both HPV 6 and 11 for analysis of HPV 6 and 11 HPV11-related endpoints), received all 3 doses of 9vHPV vaccine with the correct dose of the clinical material within 1 year, and had no other protocol violation that could interfere with evaluation of vaccine effectiveness.

Persistent infection is when a participant is positive by polymerase chain reaction (PCR) for the same HPV type in cervicovaginal/external genital swabs or tissue specimens collected at consecutive visits at least 6 months (+/-1 month visit window) apart. Incidence was estimated as cases per 10,000 person-years. Person-years follow-up was from beginning of long-term follow-up or when a study participant reached 16 years of age, whichever came later. Per protocol, the extension study included 9- to 15-year-old females regardless of lot administered.

This outcome measure was determined by clinical/pathologic criteria and positive PCR assay for HPV type. Incidence was estimated as cases per 10,000 person-years. Person-years follow-up was calculated starting from the beginning of the long-term follow-up study or the date when the study participant reached 16 years of age, whichever came later.
