Vaccines

Blinded 9vHPV vaccine (V503) 0.5 mL intramuscular injection at Day 1, Month 2, and Month 6 of the Base Study. Participants will not continue to the Extension Study.

Blinded 0.5 mL intramuscular injection of saline placebo at Day 1, Month 2, and Month 6 of the Base Study. After completion of the Base Study, participants will be eligible to receive open-label 9vHPV 0.5 mL intramuscular injection at Day 1, Month 2, and Month 6 of the Extension Study.

Medical Director

This study will evaluate whether V503 (9vHPV vaccine), is well tolerated in girls and women between 12 and 26 years old who have previously been vaccinated with GARDASIL™. Participants will receive vaccination with 9vHPV vaccine or placebo on Day 1, Month 2, and Month 6 of the Base Study. Participants who receive placebo in the Base Study will be eligible to receive vaccination with 9vHPV vaccine on Day 1, Month 2, and Month 6 of the Extension Study.

A Study of V503, a 9-valent Human Papillomavirus (9vHPV) Vaccine in Females 12-26 Years of Age Who Have Previously Received GARDASIL™ (V503-006)

A Phase III, Randomized, International, Placebo-Controlled, Double-Blind Clinical Trial to Study the Tolerability and Immunogenicity of V503, a Multivalent Human Papillomavirus (HPV) L1 Virus-Like Particle (VLP) Vaccine, Given to Females 12-26 Years of Age Who Have Previously Received GARDASIL™

An SAE is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the participant and may require medical intervention.

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 vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. The percentage of participants who reported an AE that was associated with the injection site such as redness, swelling, and pain/tenderness/soreness was summarized.

Participants collected their oral body temperature in the evening of their vaccination day and at the same time each day thereafter for 4 days. The maximum body temperature obtained within 5 days of any of the 3 vaccinations was recorded.

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 vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Systemic AEs were those not categorized as injection-site AEs.

An SAE is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the participant and may require medical intervention. An SAE that is judged by the Investigator to be "definitely related," "probably related," or "possibly related" is defined as a vaccine-related SAE.

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 vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an AE. Participants were instructed to estimate the severity of AEs such as pain at injection site as mild (awareness of symptom, but easily tolerated), moderate (discomfort enough to cause interference with usual activities), or severe (incapacitating with inability to work or do usual activity). Additionally, participants were instructed to measure any swelling and/or erythema at its greatest width. Swelling or erythema with diameter \>2 inches (\>5 cm) was recorded as severe. All AEs associated with the injection site and reported as severe were summarized.

Serum antibody titers for HPV virus-like particles (VLPs), Types 6, 11, 16, 18, 31, 33, 45, 52 and 58 were determined 4 weeks post-vaccination 3 using competitive luminex immunoassay (cLIA). The serostatus cutoffs (milli Merck U/mL) for HPV types were as follows: HPV Type 6: ≥30, HPV Type 11: ≥16; HPV Type 16: ≥20, HPV Type 18: ≥24, HPV Type 31: ≥10, HPV Type 33: ≥8, HPV Type 45: ≥8, HPV Type 52: ≥8, and HPV Type 58: ≥8.

Population included all participants who received at least 1 vaccination and had available follow-up data. Only SAEs were collected systematically in the Extension Study. Although some unsolicited non-serious AEs were reported during the Extension Study, none exceeded the 5% cut-off.
