Trial Outcomes & Findings for Immunobridging Study of 9- Valent Human Papillomavirus (9vHPV) Vaccine (V503) in Chinese Females 9 to 45 Years of Age (V503-024) (NCT NCT03903562)

NCT ID: NCT03903562

Last Updated: 2026-04-06

Results Overview

Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined using cLIA. The HPV-9 cLIA assay was used to quantify the antibodies. This assay evaluated the serological response before and after 9vHPV vaccination and measured HPV infection-induced antibodies. The GMT for each HPV type was expressed as milli Merck units/mL (mMU/mL).

PRIMARY outcome

Timeframe: 1 month post vaccination 3 (Month 7)

Population: Per protocol, included participants 9-19 and 20-26 years old who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined using cLIA. The HPV-9 cLIA assay was used to quantify the antibodies.

PRIMARY outcome

Timeframe: 1 month post vaccination 3 (Month 7)

Population: Per protocol, included participants 27-45 and 20-26 years old who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

The percentage of participants who are seropositive for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 was determined using cLIA. Seroconversion was defined as changing serostatus from seronegative at baseline (Day 1) to seropositive at 1 month after last dose. Cutoff values for HPV seropositivity are ≥50, 29, 41, 59, 29, 22, 15, 20, and 15 mMU/mL for HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58, respectively.

PRIMARY outcome

Timeframe: Month 36

Population: Per protocol, included participants 9 to 19 years of age who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined using cLIA. The HPV-9 cLIA assay was used to quantify the antibodies. This assay evaluated the serological response before and after 9vHPV vaccination and measured HPV infection-induced antibodies. The GMT for each HPV type was expressed as mMU/mL.

PRIMARY outcome

Timeframe: Month 48

Population: Per protocol, included participants 9 to 19 years of age who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

The percentage of participants who are seropositive for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 was determined using cLIA. Seroconversion was defined as changing serostatus from seronegative at baseline (Day 1) to seropositive at 1 month after last dose. Cutoff values for HPV seropositivity are ≥34, 25, 32, 26, 15, 10, 10, 14 and 10 mMU/mL for HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58, respectively.

Timeframe: Month 12

Population: Per protocol, included participants 9 to 19 years of age who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined using IgG LIA. The HPV-9 IgG LIA assay was used to quantify the antibodies. This assay evaluated the serological response before and after 9vHPV vaccination and measured HPV infection-induced antibodies. The GMT for each HPV type was expressed as mMU/mL. Although the same name (mMU/mL) is used for the unit of measurement in both cLIA and IgG LIA, the 'cLIA mMU/mL' and the 'IgG LIA mMU/mL' are actually different units of measurement and cannot be directly compared.

PRIMARY outcome

Timeframe: Month 60

Population: Per protocol, included participants 9 to 19 years of age who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined using IgG LIA. The HPV-9 IgG LIA assay was used to quantify the antibodies. This assay evaluated the serological response before and after 9vHPV vaccination and measured HPV infection-induced antibodies. The GMT for each HPV type was expressed as mMU/mL.

PRIMARY outcome

Timeframe: Month 60

Population: Per protocol, included participants 9 to 19 years of age who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine.

The percentage of participants who are seropositive for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 was determined using IgG LIA. Seroconversion was defined as changing serostatus from seronegative at baseline (Day 1) to seropositive at 1 month after last dose. Cutoff values for HPV seropositivity are ≥9, 6, 5, 5, 3, 4, 3, 5 and 5 mMU/mL for HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58, respectively.

SECONDARY outcome

Timeframe: 1 month post vaccination 3 (Month 7)

Population: Participants who 1) received all vaccinations in the planned regimen, 2) were seronegative at Day 1 for the relevant HPV type and in the analysis of HPV types 6 and 11, the participant must be seronegative to both HPV 6 and 11, 3) had a serum sample collected 1 month after last dose within an acceptable day range, and 4) had no other protocol violations that could interfere with the evaluation of participant's immune response to the study vaccine were analyzed.

Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined using IgG LIA. The HPV-9 IgG LIA assay was used to quantify the antibodies. This assay evaluated the serological response before and after 9vHPV vaccination and measured HPV infection-induced antibodies. The GMT for each HPV type was expressed as mMU/mL.

SECONDARY outcome

Timeframe: Up to 8 days post any vaccination (up to ~Day 192)

Population: The analysis population consisted of all participants who received at least 1 dose of study 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 unfavorable 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. The participant or the parent/guardian of the participant was to record the presence of any vaccination report card (VRC)-prompted injection-site AEs that occurred in the 8 days after any vaccination. The percentage of participants with an injection-site AE prompted on the VRC (erythema, pain, swelling and induration) is reported.
