OPEN-LABEL, RANDOMIZED, THREE-ARM, PHASE IIIB CLINICAL STUDY TO INVESTIGATE THE SAFETY AND IMMUNOGENICITY OF A CONCOMITANT ADMINISTRATION OF GROUP C MENINGOCOCCAL POLYSACCHARIDE-TETANUS TOXOID CONJUGATE (MENC-TT) VACCINE AND 7-VALENT PNEUMOCOCCAL CRM197-CONJUGATE VACCINE (PCV7) IN TODDLERS PREVIOUSLY IMMUNIZED DURING INFANCY WITH PCV7 - n.a.
- Conditions
- The meningococcal group C polysaccharide-tetanus toxoid (MENC-TT) conjugate vaccine used in Study 670701 is to prevent invasive disease caused by Neisseria meningitidis serogroup C by means of active immunization. The 7-valent pneumococcal CRM197 conjugate vaccine (PCV7) is for prevention of invasive disease caused by Streptococcus pneumoniae serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F via active immunization. Co-administration of both vaccines will be investigated.MedDRA version: 9.1Level: LLTClassification code 10027274Term: Meningococcal infectionMedDRA version: 9.1Level: LLTClassification code 10061353Term: Pneumococcal infection

Male and female subjects will be eligible for participation in this study if:·
- they are toddlers, aged 12 to 18 months;
- they are clinically healthy, (i.e. the physician would have no reservations vaccinating with a MenC conjugate vaccine, and/or PCV7 outside the scope of a clinical trial);
- their parents/legal guardian(s) understand the nature of the study, agree to its provisions, and provide written informed consent;
- their parents/legal guardian(s) agree to keep a Subject Diary;
- they have received a complete primary series of pneumococcal conjugate vaccine (3 vaccinations with PCV7 in the first year of life according to the official vaccination calendar recommendations).
Are the trial subjects under 18? yes
Number of subjects for this age range:
F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range
Subjects will be excluded from participation in this study if:
- they have a history of any vaccine-related contraindicating event, e.g. serious reactions after first application of a PVC7 vaccine or high fever =40ºC associated with any vaccination, or generalized allergic reaction within 48 hours of a first application of vaccine;
- they have a known sensitivity or allergy to any components of the vaccines;
- they have previously been vaccinated with MenC vaccine;
- they have already received a PVC 7 booster (4th vaccination);·
- they have a rash or other dermatological condition at the injection site which could interfere with injection site reaction evaluation;
- they suffer from a disease (e.g. autoimmune disease) or are undergoing a form of treatment (e.g. systemic corticosteroids) that can be expected to influence immunological functions;
- they have a history of meningococcal serogroup C and/or invasive pneumococcal infection;
- they have received any blood products or immunoglobulins within 90 days of study entry or the administration of such products is planned during the study period;
- currently have or had a history of any serious disease (e.g. cardiac, renal, autoimmune, neurologic);
- were administered an investigational drug within six weeks prior to study entry or are concurrently participating in a clinical study that includes the administration of an investigational product;
- they or their parents/legal guardian(s) are in a dependent relationship with the study investigator or with a study team member. Dependent relationships include close relatives (i.e., children or grandchildren, partner/spouse, siblings) as well as employees of the investigator or site conducting the study.

Name Time Method Main Objective: To demonstrate that the concomitant administration of a single dose of MenC-TT vaccine and a PCV7 booster does not influence the immune response to the seven pneumococcal strains contained in PCV7 as compared to administration of PCV7 alone.<br><br>To demonstrate that the concomitant administration of a single dose MenC-TT vaccine and a PCV7 booster does not influence the immune response to the MenC vaccine as compared to administration of MenC-TT vaccine alone.;Secondary Objective: n.a.;Primary end point(s): Immunogenicity:<br>- Number of subjects achieving PCV7- specific (elicited by each vaccine pneumococcal serotype) antibody concentrations of at least 0.2 mg/mL one month after a booster vaccination with PCV7;<br>- Number of subjects achieving sero-protective levels of meningococcal serogroup C (MenC) specific serum bactericidal activity (SBA), defined as titer =1:8, one month after administration of MenC-TT vaccine.
