Immunogenicity and Safety of an Investigational Quadrivalent Meningococcal Conjugate Vaccine in Healthy Adolescents

Study Overview
=================
Brief Summary
-----------------
The purpose of the study was to evaluate the immunogenicity and describe the safety of Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine compared to the licensed vaccine MENVEO® in adolescents 10 to 17 years of age in the United States (US). This study also evaluated the immunogenicity and safety of MenACYW Conjugate vaccine when given alone compared to when given concomitantly with tetanus, diphtheria, acellular pertussis (Tdap) vaccine and human papilloma virus (HPV) vaccine. Primary objective: To evaluate the antibody responses to the antigens present in MenACYW Conjugate vaccine when MenACYW Conjugate vaccine was given alone compared to those when MENVEO vaccine was given alone. Secondary objective: To evaluate the antibody responses to the antigens present in MenACYW Conjugate vaccine, when MenACYW Conjugate vaccine was given concomitantly with Tdap and HPV vaccines, compared to those when it was given alone. To evaluate the antibody responses to the antigens present in Tdap vaccine, when Tdap vaccine was given concomitantly with MenACYW Conjugate vaccine and HPV vaccine, compared to those when Tdap vaccine was given with HPV vaccine only. To evaluate the antibody responses to the antigens present in HPV vaccine after the 3-dose series, when the first dose of HPV vaccine is given concomitantly with MenACYW Conjugate vaccine and Tdap vaccine, compared to those when the first dose of HPV vaccine is given with Tdap vaccine only. Observational objective: To describe the safety profile of MenACYW Conjugate vaccine, compared to that of the licensed vaccine MENVEO®, and when MenACYW Conjugate vaccine was given with Tdap and HPV vaccines.

Detailed Description
-----------------
Healthy adolescents were randomized and received a single dose of their assigned vaccines. They were assessed for immunogenicity at baseline (pre-vaccination) and at 30 days post-vaccination. Safety information were collected post-vaccination and throughout the entire study.

At high risk for meningococcal infection during the trial (i.e., participants with persistent complement deficiency, with anatomic or functional asplenia, or participants travelling to countries with high endemic or epidemic disease). Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances, including encephalopathy (e.g., coma, decreased level of consciousness, prolonged seizures) within 7 days of administration of a previous pertussis antigen-containing vaccine. Personal history of Guillain-Barré syndrome. Personal history of an Arthus-like reaction after vaccination with a tetanus toxoid-containing vaccine within at least 10 years of the proposed study vaccination.

Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily. Current alcohol abuse or drug addiction. Chronic illness (e.g., human immunodeficiency virus [HIV] hepatitis B, hepatitis C) that, in the opinion of the investigator, was at a stage where it might interfere with trial conduct or completion. Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature >= 100.4 degree fahrenheit [°F]). A prospective participant was not included in the study until the condition had resolved or the febrile event had subsided. Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw. Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e., natural or adopted child) of the Investigator or employee with direct involvement in the proposed study.
