Efficacy and Tolerability Study of V501 in Japanese Males (V501-122)

Phase 3
Completed
Conditions
Condyloma Acuminata
Anogenital Human Papilloma Virus Infection
Interventions
Biological: Placebo
Biological: V501
Registration Number
NCT01862874
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

A study to evaluate the efficacy and tolerability of V501 (quadrivalent Human Papilloma Virus \[HPV\] \[Type 6, 11, 16 and 18\] L1 Virus-Like Particle vaccine, GARDASIL™) in healthy, 16- to 26-year old Japanese males. The hypotheses tested are: 1) V501 reduces the combined incidence of HPV 6-, 11-, 16-, or 18-related persistent infection compared with placebo, and 2) V501 reduces the combined incidence of HPV 6-, 11-, 16-, or 18-related persistent infection, condyloma acuminata, penile/perianal/perineal intraepithelial neoplasia, or penile, perianal, or perineal cancer compared with placebo.

Primary Outcome Measures
NameTimeMethod
Combined Incidence of HPV Type 6, 11, 16, or 18-related Persistent InfectionUp to Month 36

Persistent infection was defined as 1) polymerase chain reaction (PCR) positive to HPV Type 6, 11, 16, or 18 in 2 consecutive anogenital or biopsy samples collected ≥4 months apart, or 2) Pathology Panel consensus diagnosis of condyloma acuminate, penile/perianal/perineal intraepithelial neoplasia (PIN), penile, perianal, or perineal cancer and PCR detection of HPV Type 6, 11, 16, or 18 in an adjacent section and PCR positive for the same HPV type at a separate adjacent visit. The combined incidence of HPV Type 6, 11, 16, or 18 persistent infection detected in samples from ≥2 consecutive visits ≥6 months apart was assessed.

Percentage of Participants With a Vaccine-related Systemic Adverse EventUp to 15 days after 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 drug. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug or a protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study drug or protocol-specified procedure is also an AE. Vaccine-related AEs are those that were deemed possibly, probably, or definitely related to vaccine administration by the investigator. The percentage of participants with a vaccine-related systemic AE was summarized.

Percentage of Participants With an Injection-site Adverse Event Prompted on the Vaccination Report CardUp to 5 days after 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 drug. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug or a protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study drug or protocol-specified procedure is also an AE. The percentage of participants with an injection-site AE prompted on the VRC (erythema, pain, and swelling) was summarized.

Percentage of Participants With Maximum Temperature ≥37.5°C Reported on the Vaccination Report CardUp to 5 days after any vaccination

Body temperature (oral or oral equivalent) was recorded on the Vaccination Report Card (VRC). The percentage of participants with a maximum temperature ≥37.5°C was summarized.

Percentage of Participants With a Systemic Adverse EventUp to 15 days after 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 drug. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug or a protocol-specified procedure, whether or not considered related to the study drug or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study drug or protocol-specified procedure is also an AE. The percentage of participants with a systemic AE was summarized.

Secondary Outcome Measures
NameTimeMethod
Combined Incidence of HPV Type 6, 11, 16, or 18-related Persistent Infection or DiseaseUp to Month 36

Persistent infection was defined as 1) polymerase chain reaction (PCR) positive to HPV Type 6, 11, 16, or 18 in 2 consecutive anogenital or biopsy samples collected ≥4 months apart, or 2) Pathology Panel consensus diagnosis of condyloma acuminate, penile/perianal/perineal intraepithelial neoplasia (PIN), penile, perianal, or perineal cancer and PCR detection of HPV Type 6, 11, 16, or 18 in an adjacent section and PCR positive for the same HPV type at a separate adjacent visit. The incidence of persistent infection detected in samples from ≥2 consecutive visits ≥6 months apart was assessed. Disease was defined as HPV Type 6, 11, 16, or 18-related condyloma acuminate, PIN, penile, perianal, or perineal cancer. The combined incidence of HPV Type 6, 11, 16, or 18 persistent infection or disease was assessed.
