Immunogenicity and Tolerability of Broad Spectrum Human Papillomavirus (HPV) Vaccine in Adult and Young Adult Women (V503-004)

Phase 3

Completed

• Conditions: Vulvar Cancer; Cervical Cancer; Vaginal Cancer; Genital Warts; Human Papillomavirus Infection

• Registration Number: NCT03158220
• Lead Sponsor: Merck Sharp & Dohme LLC

Brief Summary

This study will assess the safety and immunogenicity of GARDASIL®9 (V503) in 16- to 45-year-old women. The primary hypothesis of the study states that anti-HPV 16, 18, 31, 33, 45, 52, and 58 geometric mean titers (GMTs) at 4 weeks postdose 3 are non-inferior in adult women as compared with GMTs in young adult women.

Primary Outcome Measures

Name	Time	Method
Anti-HPV Geometric Mean Titers (GMTs) for Each Anti-HPV Type	4 weeks post vaccination 3 (Month 7)	Antibodies to the HPV types contained in V503 were measured using a competitive luminex immunoassay. Antibody titers were expressed as milli Merck units/mL (mMU/mL). Statistical comparisons between arms was performed for the HPV types considered oncogenic (HPV Types 16/18/31/33/45/52/58).

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants With at Least 1 Solicited Injection-site Adverse Event	Up to 5 days post any vaccination	Participants were asked to record any injection-site reactions prompted in the Vaccination Report Card, i.e., injection-site tenderness, swelling, or redness, occurring after each study vaccination (solicited injection-site reactions). The percentage of participants with 1 or more solicited injection-site AE was assessed.
Percentage of Participants With Elevated Temperature (Fever)	Up to 5 days post any vaccination	Participants were asked to record oral body temperature in the Vaccination Report Card. The percentage of participants with elevated temperature (≥37.8°C or 100.0°F) was assessed.
Percentage of Participants That Experienced at Least 1 Adverse Event (AE)	Up to 1 month post vaccination 3 (up to 7 months)	An AE is any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The percentage of participants with 1 or more AEs was assessed.
Percentage of Participants Who Had Study Vaccine Discontinued Due to Adverse Event.	Up to 1 month post vaccination 3 (up to 7 months)	An adverse event is any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event. The percentage of participants who discontinued the study vaccine due to an adverse event regardless of study completion status was assessed.
Percentage of Participants That Reported at Least 1 Systemic Adverse Event	Up to 15 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. Systemic AEs are those not categorized as injection-site AEs. The percentage of participants that reported at least 1 systemic AE was assessed
Percentage of Participants Who Seroconverted to Each of the Anti-HPV Types	4 weeks post vaccination 3 (Month 7)	Antibodies to the HPV types contained in V503 were measured using a competitive luminex immunoassay. The percentage of participants who were seronegative on Day 1 and have anti-HPV titer greater or equal to the type-specific serostatus cutoff at 4 weeks postdose 3 was assessed.
