Immunobridging Study of 9- Valent Human Papillomavirus (9vHPV) Vaccine (V503) in Chinese Females 9 to 45 Years of Age (V503-024)
- Registration Number
- NCT03903562
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
This study will investigate the immunogenicity and safety of the 9vHPV vaccine in healthy Chinese females 9 to 45 years of age. The study consists of Stage I (Day 1 to Month 7) and Stage II (post Month 7 to Month 60). Stage II will report the long-term immunogenicity and safety in the 9-19 year-old age group only. The dual-primary hypotheses of Stage I are that 9vHPV vaccine induces non-inferior immune responses in females 9 to 19 years of age who are seronegative at Day 1 to the relevant HPV type compared to females 20 to 26 years of age who are seronegative at Day 1 to the relevant HPV type, as measured by anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 GMTs at 1 month post Dose 3, and 9vHPV vaccine induces non-inferior immune responses in females 27 to 45 years of age who are seronegative at Day 1 to the relevant HPV type compared to females 20 to 26 years of age who are seronegative at Day 1 to the relevant HPV type, as measured by the seroconversion percentages to each of HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58 at 1 month post Dose 3. (Each vaccine component will be analyzed separately.)

Stage I: Percentage of Participants Who Experience at Least 1 Systemic AE 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. The percentage of participants with a systemic AE will be summarized.
Stage I: Percentage of Participants Who Experience at Least 1 Serious Adverse Event (SAE) Day 1 to Month 7 An 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 study vaccine, whether or not considered related to the use of the study vaccine. 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. The percentage of participants that experienced 1 or more SAEs will be summarized.

The percentage of participants who are seropositive for each HPV type will be summarized.
Stage I: Percentage of Participants Who Experience at Least 1 Solicited Injection-site AE Up to 8 days post any vaccination An adverse event (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. The participant or the parent/guardian of the participant were 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) will be summarized.
Stage I: IgG LIA GMTs for HPV Types 6, 11, 16, 18, 31, 33, 45, 52, and 58 in Participants 9 to 19 Years of Age, 20 to 26 Years of Age, and 27 to 45 Years of Age: Month 7 1 month post vaccination 3 (Month 7) Serum antibody titers for HPV types 6, 11, 16, 18, 31, 33, 45, 52 and 58 will be determined using IgG LIA. The GMT for each HPV type will be reported in mMU/mL.
Stage II: Percentage of Participant 9 to 19 years of Age Who Experience at Least 1 Serious Adverse Event (SAE): Month 7 to Month 60 Month 7 to Month 60 An 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 study vaccine, whether or not considered related to the use of the study vaccine. 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. The percentage of participants that experienced 1 or more SAEs will be summarized.
