Clinical Trial Summary

The aim of the study was to assess whether the second CYD dengue vaccination could be administered concomitantly with the booster vaccination of a pediatric combination vaccine (Pentaxim™) during the same day visit but in 2 different sites of administration. Primary Objective: - To demonstrate the non-inferiority of the antibody response against all antigens (diphtheria, tetanus, pertussis, polio and Haemophilus influenzae type b (Hib)) in participants receiving one booster dose of Pentaxim™ vaccine administered concomitantly with the second dose of CYD dengue vaccine compared to participants receiving one booster dose of Pentaxim™ vaccine administered concomitantly with placebo. Secondary Objectives: - To describe the safety of Pentaxim™ vaccine administered concomitantly with the second dose of CYD dengue vaccine, or administered concomitantly with placebo. - To describe the safety of the CYD dengue vaccine after the second dose of CYD dengue vaccine administered concomitantly with Pentaxim™ vaccine (at Visit 05) or administered alone (at Visit 06). - To describe the safety of the CYD dengue vaccine in all participants after each dose. - To describe the antibody response to each dengue virus serotype (post-Dose 2 and post-Dose 3) after the second dose of CYD dengue vaccine administered concomitantly with Pentaxim vaccine (at Visit 05) or administered alone (at Visit 06). - To describe the antibody response to each dengue virus serotype post-Dose 2 and post-Dose 3.

Description:

Participants required 8 or 9 clinic visits and received a total of 7 injections. The dengue post-vaccinal viremia was assessed at Visit 2 from a subset of toddlers. The dengue immunogenicity was assessed 28 days after CYD dengue dose 2 and dose 3 from a subset of toddlers. Participants were followed-up for safety after each vaccine dose and for 6 months after the last dengue vaccination.

Primary	Percentage of Participants With Seroprotection or Booster Response After a Booster Injection (Inj.) of Diphtheria, Tetanus, Acellular Pertussis(DTaP)-Inactivated Polio Virus (IPV)//Hib (Pentaxim™) Administered Concomitantly With CYD Dengue Vaccine	Antibodies (Ab) against diphtheria, tetanus toxoid, pertussis toxoid (PT), and filamentous hemaglutinin (FHA) was measured by enzyme-linked immunosorbent assay (ELISA), polyribosylribitol phosphate (PRP) by Farr-type radioimmunoassay, and poliovirus types 1, 2, and 3 by seroneutralization assay. Seroprotection was defined as >=0.1 International Unit (IU)/mL for diphtheria toxoid and tetanus toxoid, >=8 1/dil for poliovirus types 1, 2, and 3, and >=1.0 µg/mL for PRP. Booster response to PT and FHA: participants whose pre-vaccination Ab titers were < lower limit of quantitation (LLOQ), a booster response occurred if they had post-vaccination levels >=4* LLOQ; participants whose pre-vaccination Ab concentrations were >=LLOQ but <4* LLOQ, a booster response occurred if they had a 4-fold increase (post/pre-vaccination levels >=4); for participants whose pre-vaccination Ab concentrations were >=4* LLOQ, a booster response occurred if they had a 2-fold increase (post/pre-vaccination >=2).	28 days post-injection
