Immunogenicity and Safety of a Booster Dose of an Investigational Quadrivalent Meningococcal Conjugate Vaccine

March 24, 2022 updated by: Sanofi Pasteur, a Sanofi Company

Immunogenicity and Safety of a Booster Dose of an Investigational Quadrivalent Meningococcal Conjugate Vaccine in Adolescents and Adults

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Seroresponse to Meningococcal Serogroups A, C, Y, and W Following Vaccination With Either MenACYW Conjugate Vaccine or Menactra® Vaccine
Time Frame: Day 30 (post-vaccination)
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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
Time Frame: Day 6 (post-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)
Geometric Mean Titers Against Meningococcal Serogroups A, C, Y, and W Antibodies Following Vaccination With Either MenACYW Conjugate Vaccine or Menactra® Vaccine
Time Frame: Day 30 (post-vaccination)
Meningococcal antibody responses against Serogroups A, C, Y, and W were measured by hSBA.
Day 30 (post-vaccination)
Number of Participants With Solicited Injection Site Reactions or Systemic Reactions Following Vaccination With Either MenACYW Conjugate Vaccine or Menactra® Vaccine
Time Frame: Within 7 days post-vaccination
A Solicited Reaction (SR) was an Adverse Event (AE) that was prelisted (i.e., solicited) in the electronic case report form (eCRF) and considered to be related to vaccination (adverse drug reaction). Solicited injection site reactions: Pain (Grade 1: no interference with activity, Grade 2: some interference with activity, Grade 3: significantly prevent daily activity), erythema and swelling (Grade 1: >=25 millimeter [mm] to <= 50 mm, Grade 2: >=51 to <=100 mm, Grade 3: > 100 mm). Solicited systemic reactions: Fever (Grade 1: >=38.0 degree Celsius (°C) to <=38.4°C, Grade 2: >=38.5°C to <=38.9 °C, Grade 3: >= 39°C), headache, malaise, and myalgia (Grade 1: no interference with activity, Grade 2: some interference with activity, Grade 3: significant; prevents daily activity. Number of participants with any of the Grade (1, 2 or 3) and with each Grade (1, 2 and 3) solicited injection-site and systemic reactions were reported.
Within 7 days post-vaccination
