Study of Reduced Dose of Menomune® in Children Who Previously Received Meningococcal Diphtheria Toxoid Conjugate Vaccine

January 21, 2014 updated by: Sanofi Pasteur, a Sanofi Company

Antibody Responses to a Reduced Dose of Menomune® in Children Who Previously Received an Experimental Tetravalent (A, C, Y, and W-135) Meningococcal Diphtheria Toxoid Conjugate Vaccine, TetraMenD

This study was designed to simulate meningococcal challenge by vaccination with a fractional combined dose of unconjugated meningococcal polysaccharides A, C, Y, and W-135, Menomune® in children who were vaccinated with one dose of TetraMenD at least 18 months earlier.

Primary Objective:

To evaluate and compare the antibody responses to a reduced dose of Menomune® in participants who had previously received a tetravalent meningococcal diphtheria toxoid conjugate vaccine to those responses in participants who received the same reduced dose of Menomune® but had not previously received any meningococcal vaccine.

Detailed Description

This was a two stage, controlled, open-label trial. Stage I of the trial simulated meningococcal challenge Stage II of the trial evaluated the meningococcal vaccine naïve participants from Stage I, who had also received a reduced dose of Menomune® vaccine in Stage I and were administered a full dose of Menactra® vaccine 6 months later.

Description

Inclusion Criteria :

  • Stage I
  • Participant is healthy, as determined by medical history and physical examination.
  • Participant is at least 3 years of age but not yet 6 years of age at the enrolment.
  • For the TetraMenD group: received one dose of TetraMenD as a participant in trial 603-02 no less than 18 months prior to enrolment
  • For the Control group: no previous history of any meningococcal vaccination
  • Parent/Guardian has signed Institutional Review Board- (IRB-) approved informed consent form.
  • Stage II
  • Participant is healthy, as determined by medical history and physical examination.
  • Participant is at least 3 years of age but not yet 6 years of age at the time of enrollment in Stage 1.
  • Enrolled in the Control group only and received one dose of the reduced dose Menomune at Stage 1.
  • Parent/Guardian has signed Institutional Review Board- (IRB-) approved informed consent form.

Exclusion Criteria :

  • Serious chronic disease (i.e., cardiac, renal, neurologic, metabolic, rheumatologic, psychiatric etc.)
  • Known or suspected impairment of immunologic function
  • Acute medical illness with or without fever within the last 72 hours or an axillary temperature (≥ 99.5ºF [≥ 37.5ºC]) at the time of inclusion
  • For Stage I, history of documented invasive meningococcal disease or previous meningococcal vaccination with exception of those participants recruited from Trial 603-02.
  • For Stage II, history of documented invasive meningococcal disease or participant did not receive Reduced-dose Menomune® six months prior.
  • Administration of immune globulin, other blood products within the last three months, injected or oral corticosteroids or other immunomodulatory therapy within six weeks of the study vaccine. Individuals on a tapering dose schedule of oral steroids lasting < 7 days may be included in the trial as long as they have not received more than one course within the last two weeks prior to enrollment.
  • Antibiotic therapy within the 72 hours prior to vaccination or antibiotic therapy within the 72 hours prior to having any blood sample drawn
  • Received any vaccine in the 28-day period prior to study vaccination, or scheduled to receive any vaccination during the 28-day period after study vaccination in Stage 1 of the trial.
  • Suspected or known hypersensitivity to any of the vaccine components
  • Unavailable for the entire study period or unable to attend the scheduled visits or to comply with the study procedures
  • Enrolled in another clinical trial
  • Any condition, which, in the opinion of the investigator, would pose a health risk to the participant or interfere with the evaluation of the vaccine.
