Study of a Booster Injection of Pentaxim™ Vaccine Administered With Dengue Vaccine in Healthy Toddlers

March 15, 2022 updated by: Sanofi Pasteur, a Sanofi Company

Immunogenicity and Safety of a Booster Injection of DTaP-IPV//Hib (Pentaxim™) Administered Concomitantly With Tetravalent Dengue Vaccine in Healthy Toddlers Aged 15 to 18 Months in Mexico

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.

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

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.

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 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
Time Frame: 28 days post-injection
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
