Brief summary

New immunization recommendations in the US include vaccination of adolescents against pertussis and meningococcal disease. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention recommends that Tdap (Tetanus Toxoid, Reduced Diphtheria Toxoid And Acellular Pertussis Vaccine Adsorbed) and MCV4 (Meningococcal conjugate vaccine against serotypes A, C, Y and W-135) vaccines be administered to adolescents at the same office visit if vaccination with both vaccines is indicated. Therefore, this study is designed to evaluate the safety and immunogenicity of a booster vaccination with Boostrix co-administered with Menactra as compared to the administration of either vaccine alone in healthy adolescents 11 - 18 years of age.

Detailed description

A phase IV, randomized, partially blinded multicenter study to evaluate the safety and immunogenicity of a booster vaccination with GlaxoSmithKline's tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine, adsorbed \[Tdap Boostrix®\] co-administered intramuscularly with Aventis-Pasteur's meningococcal (serogroups A, C, Y and W-135) polysaccharide diphtheria toxoid conjugate vaccine (Menactra™) as compared to the administration of either vaccine alone in healthy adolescents 11-18 years of age. Experimental design: Prospective, randomized, controlled multicenter study with three groups: Group 1: Boostrix + Menactra on Day 0, blood samples at Month 0 and Month 1 Group 2: Boostrix on Day 0, Menactra at Month 1, blood samples at Month 0, Month 1, and Month 2 Group 3: Menactra on Day 0, Boostrix at Month 1, blood samples at Month 0, Month 1 and Month 2 Treatment allocation: randomized 1:1:1 Type of study: self-contained Duration of the study: Approximately one month for each subject in Group 1 and approximately two months for each subject in the Group 2 and Group 3.

Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms

Assessed solicited general symptoms were fatigue, fever \[defined as oral temperature equal to or above 37.5 degrees Celsius (°C)\], headache and gastrointestinal symptoms \[gastro sympt\]. Any = any solicited general symptom irrespective of intensity grade or relationship to vaccination. Grade 3 = symptoms that prevented normal activities. Grade 3 Fever = temperature higher than (\>) 39° C. Related = symptoms considered by the investigator to have a causal relationship to vaccination. Gastrointestinal symptoms included nausea, vomiting, diarrhea and/or abdominal pain.

Time frame: Within 4-days (Days 0-3) after each dose and across doses

Population: The analysis was performed on the Total Vaccinated cohort, which included all subjects with at least one vaccine administration documented and with the symptom sheet completed.

Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs)

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE =An AE which prevented normal, everyday activities. Such an AE, for example, prevented attendance at work/school and necessitated the administration of corrective therapy. Related = AE assessed by the investigator as related to the vaccination.

Time frame: Within the 31-day (Days 0-30) period after each vaccination

Population: The analysis was performed on the Total Vaccinated cohort, which included all subjects with at least one vaccine administration documented.

Number of Subjects With Booster Responses for Anti-diphtheria (Anti-D) and Anti-tetanus (Anti-T) Antibodies

Booster responses for anti-D and anti-T antibodies were defined as: for initially seronegative subjects (pre-vaccination concentration below the cut-off concentration of 0.1 IU/mL): antibody concentrations at least four times the cut-off (postvaccination concentration ≥ 0.4 IU/mL), one month after vaccination with the Boostrix vaccine; and for initially seropositive subjects (pre-vaccination concentration ≥ 0.1 IU/mL): an increase in antibody concentrations of at least four times the pre-vaccination concentration one month after vaccination with the Boostrix vaccine.

Time frame: At one month POST Boostrix vaccination (Month 1 for Boostrix + Menactra Group and Boostrix-Menactra Group/ Month 2 for Menactra-Boostrix Group)

Population: The analysis was performed on the According-To-Protocol cohort for immunogenicity, which included all evaluable subjects with immunogenicity data available \& randomization code not broken who had received at least 1 dose of study vaccine (known administration site) \& had not received a vaccine not specified or forbidden by the protocol.
