Safety and Immunogenicity of 9-valent Human Papillomavirus (9vHPV) Vaccine Coadministered With Messenger Ribonucleic Acid (mRNA)-1273 Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (COVID-19) Vaccine (V503-076)

Phase 3
Completed
Conditions

Biological: 9vHPV Vaccine
Biological: mRNA-1273 Vaccine
Registration Number
NCT05119855
Lead Sponsor

Brief Summary

The purpose of this study to evaluate the safety and immunogenicity of a 2-dose regimen of 9vHPV vaccine, where the first dose is administered concomitantly with a first dose of a 2-dose regimen of mRNA-1273 vaccine versus nonconcomitant administration of 9vHPV and mRNA-1273 vaccines in boys and girls 9 to 11 years of age.

Primary Outcome Measures
NameTimeMethod
Geometric Mean Titers of Anti-Human Papillomavirus Types 6, 11, 16, 18, 31, 33, 45, 52, and 584 weeks post vaccination 2

Serum antibodies to human papillomavirus (HPV) types 6, 11, 16, 18, 31, 33, 45, 52, and 58 will be measured with a competitive luminex immunoassay (cLIA). Titers are reported in milli Merck Units/mL.

Geometric Mean Concentrations of SARS-CoV-2 Spike Protein-Specific Binding Antibodies4 weeks post vaccination 2

Serum antibodies to SARS-CoV-2 spike protein measured by electrochemiluminescence (ECL)

Percentage of Participants with at Least 1 Solicited Injection-site Adverse EventUp to Day 7 post vaccination

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited AEs are predefined local (at the injection site) for which the participant is specifically questioned, and which are noted by the participant in their vaccine report card (VRC).

Percentage of Participants with at Least 1 Solicited Systemic AEUp to Day 7 post vaccination

An AE is any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited AEs are predefined systemic events for which the participant is specifically questioned, and which are noted by the participant in their VRC.

Percentage of Participants with at Least 1 Serious Adverse EventUp to ~Month 9

A serious adverse event (SAE) is defined as one that results in death, is life threatening, or requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly or birth defect, or other important medical event that may require medical intervention.

Percentage of Participants with at Least 1 Vaccine-Related SAEUp to ~Month 9

An SAE is defined as one that results in death, is life threatening, or requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly or birth defect, or other important medical event that may require medical intervention. An SAE that is judged by the investigator to be related to the study vaccine is a vaccine-related SAE.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Who Seroconvert to Each of the 9vHPV Vaccine Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 Following Administration of a 2-Dose Regimen of 9vHPV Vaccine4 weeks post vaccination 2

Serum antibodies to human papillomavirus (HPV) types 6, 11, 16, 18, 31, 33, 45, 52, and 58 will be measured with a competitive luminex immunoassay (cLIA). Percentage of participants who seroconverted will be assessed.

Percentage of Participants Who Experience Seroresponse Following Administration of a 2-Dose Regimen of mRNA-1273 Vaccine4 weeks post vaccination 2

Serum antibodies to SARS-CoV-2 spike protein measured by ECL assay. Percentage of participants who experience seroresponse will be assessed.
