Clinical Trial Summary

The aim of the study was to describe the safety and antibody response to booster administration with Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine in participants who received their first quadrivalent meningococcal Conjugate vaccine dose in the past 4-10 years. Primary Objective: - To demonstrate the non-inferiority of the vaccine seroresponse of meningococcal serogroups A, C, Y, and W following the administration of a booster dose of MenACYW Conjugate vaccine compared to those observed following the administration of a booster dose of Menactra® in participants who were first vaccinated with 1 dose of a quadrivalent meningococcal vaccine 4 to 10 years before the booster dose. Secondary Objectives: - To evaluate the vaccine seroresponse of meningococcal serogroups A, C, Y, and W measured using human serum bactericidal assay (hSBA) in serum specimens collected 6 days after vaccination in a subset of 120 participants. - To evaluate the antibody responses (geometric mean titers) to serogroups A, C, Y, and W measured using hSBA on Day 0 (pre-vaccination) and Day 30 after vaccination. Observational Objectives: - To describe the antibody titers against meningococcal serogroups A, C, Y, and W measured by hSBA assessed at Day 0, Day 6, and Day 30 days after vaccination. - To describe the antibody responses to the meningococcal serogroups A, C, Y, and W before and 30 days after vaccination with MenACYW Conjugate vaccine or Menactra® measured by rabbit serum bactericidal assay (rSBA) in a subset of participants. - To describe the safety profile of MenACYW Conjugate vaccine compared to that of a licensed Menactra® after booster vaccination.

Description:

Healthy adolescents and adults who had received 1 dose of a quadrivalent meningococcal Conjugate vaccine 4 to 10 years previously were randomized to receive either 1 dose of MenACYW Conjugate vaccine or licensed Menactra®. All participants underwent immunogenicity assessment at baseline (pre-vaccination) and post-vaccination and were also evaluated for safety up to Day 180 post-vaccination. In addition, a subset had an additional blood sample collected at 6 days post-vaccination for immunogenicity assessment.

• Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccine(s) used in the trial or to a vaccine containing any of the same substances.
• Personal history of an Arthus-like reaction after vaccination with a tetanus toxoid-containing vaccine.
• Personal history of Guillain-Barré syndrome.
• Verbal report of thrombocytopenia, contraindicating intramuscular vaccination in the Investigator's opinion.
• Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination in the Investigator's opinion.
• 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 that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion.
• Moderate or severe acute illness/infection (according to the Investigator's judgment) on the day of vaccination or febrile illness (temperature >= 100.4°Fahrenheit [F]). A prospective participant should not be included in the study until the condition has resolved or the febrile event has 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., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Seroresponse to Meningococcal Serogroups A, C, Y, and W Following Vaccination With Either MenACYW Conjugate Vaccine or Menactra® Vaccine	The serum bactericidal assay using human complement (hSBA) vaccine seroresponse for serogroups A, C, Y, and W was defined as post-vaccination hSBA titers >= 1:16 for participants with pre-vaccination hSBA titers < 1:8 or at least a 4-fold increase in hSBA titers from pre- to post-vaccination for participants with pre-vaccination hSBA titers >= 1:8.	Day 30 (post-vaccination)
Secondary	Percentage of Participants With Seroresponse to Meningococcal Serogroups A, C, Y, and W Following Vaccination With Either MenACYW Conjugate Vaccine or Menactra® Vaccine at Day 6 After Vaccination	The hSBA vaccine seroresponse for serogroups A, C, Y, and W was defined as post-vaccination hSBA titers >= 1:16 for participants with pre-vaccination hSBA titers < 1:8 or at least a 4-fold increase in hSBA titers from pre- to post-vaccination for participants with pre-vaccination hSBA titers >= 1:8.	Day 6 (post-vaccination)
Secondary	Geometric Mean Titers Against Meningococcal Serogroups A, C, Y, and W Antibodies Following Vaccination With Either MenACYW Conjugate Vaccine or Menactra® Vaccine	Meningococcal antibody responses against Serogroups A, C, Y, and W were measured by hSBA.	Day 30 (post-vaccination)
