This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722). The objectives are:

  • To describe the antibody persistence to any antigen contained in the investigational DTaP-IPV-Hep B-PRP-T vaccine and Infanrix hexa™ prior to the booster dose
  • To describe the safety and immunogenicity of the booster dose of either DTaP-IPV-Hep B-PRP-T or Infanrix hexa™ vaccine.
  • To describe the immunogenicity of a booster dose of Prevenar™ given at 12 to 24 months.
Read the detailed description

All participants who completed trial A3L24 (NCT01177722) will be recruited to participate in this trial. Those who received DTaP-IPV-Hep B-PRP-T combined vaccine will be randomized to receive either a booster dose of DTaP-IPV-Hep B-PRP-T or Infanrix hexa™ vaccine.

Those who received Infanrix hexa™ will receive a booster dose of DTaP-IPV-Hep B-PRP-T combined vaccine. All participants will receive a booster dose of Prevenar™ concomitantly.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Summary of Diphtheria and Tetanus Post Primary Series Antibodies, Persistence and Booster Response Following Vaccination With Either DTaP-IPV Hep B-PRP T Vaccine or Infanrix Hexa Vaccine

    Anti-Diphtheria (D) antibodies were measured by a toxin neutralization test. Anti-Tetanus (T) antibodies were measured by enzyme-linked immunosorbent assay (ELISA). Antibody persistence for anti-Diphtheria and anti-Tetanus antibodies was defined as titers ≥0.01 IU/mL and ≥0.1 IU/mL before the booster dose at Day 0. Booster response to Diphtheria and Tetanus was defined as antibody titers ≥0.01 IU/mL and ≥0.1 IU/mL at Day 30 post-booster vaccination.

    Day 140 = Primary series; Day 0 = Pre-booster; and Day 30 = Post-booster titers

    Measured: Day 140 (Primary series) and Day 0 (Pre-booster)

  2. Summary of Pertussis and Filamentous Haemagglutinin Post Primary Series Antibodies, Persistence and Booster Response Following Vaccination With Either DTaP-IPV-Hep B-PRP~T Vaccine or Infanrix Hexa Vaccine

    Anti-Pertussis toxin (PT) and anti-Filamentous haemagglutinin (FHA) antibodies were measured by ELISA. Antibody persistence for anti-PT and anti-FHA was defined as titers ≥ lower limit of quantitation (LLOQ) before the booster dose at Day 0. Booster responses for PT and FHA at Day 30 were defined as: pre-vaccination antibody concentrations < LLOQ and post-vaccination levels ≥ 4 x LLOQ, pre-vaccination antibody concentrations ≥ LLOQ but < 4 x LLOQ and post/pre vaccination ≥ 4, and pre-vaccination antibody concentrations ≥ 4 x LLOQ and post/pre-vaccination ≥ 2.

    Day 140 = Primary series; Day 0 = Pre-booster; and Day 30 = Post-booster titers.

    Measured: Day 140 after primary vaccination, Day 0 (pre-vaccination), and Day 30 after final booster vaccination

  3. Summary of Polio Antibodies Post Primary Series, Persistence and Booster Response Following Vaccination With Either DTaP-IPV-Hep B-PRP~T Vaccine or Infanrix Hexa Vaccine

    Anti-Poliovirus types 1, 2, and 3 antibodies were measured by neutralization assay. Antibody persistence for anti-Poliovirus 1, 2, and 3 was defined as antibody titers ≥8 (1/dil) before the booster dose at Day 0. Booster response to Poliovirus 1, 2, and 3 was defined as antibody titers ≥8 (1/dil) at Day 30.

    Day 140 = Primary series; Day 0 = Pre-booster; and Day 30 = Post-booster titers.

    Measured: Day 140 after primary vaccination, Day 0 (pre-vaccination), and Day 30 after final booster vaccination

  4. Summary of Hepatitis B and Haemophilus Influenzae Type B Post Primary Series Antibodies; Antibody Persistence, and Booster Response Following Vaccination With Either DTaP-IPV-Hep B-PRP~T Vaccine or Infanrix Hexa Vaccine

    Anti-Hepatitis B antibodies were measured by the commercially available VITROS ECi/ECiQ Immunodiagnostic System. Anti-Haemophilus influenza type b capsular polyribosyl ribitol phosphate (PRP) antibodies were measured using a Farr type radioimmunoassay that used radiolabeled PRP (3H PRP) in the presence of 36Cl (volume marker). Anti-Hepatitis antibody titers ≥ 10 mIU/mL and ≥ 100 mIU/mL at Day 0 confirmed antibody persistence and booster response at Day 30. Anti-PRP antibody titers ≥ 0.15 µg/ml and ≥ 1.0 µg/ml at Day 0 confirmed antibody persistence and booster response at Day 30.

    Day 140 = Primary series; Day 0 = Pre-booster; and Day 30 = Post-booster titers.

    Measured: Day 140 after primary vaccination, Day 0 (pre-vaccination), and Day 30 after final booster vaccination

Secondary outcomes (7)
  1. Summary of Geometric Mean Titers to Vaccine Antibodies Post Primary Vaccination Series; Before and After Booster Vaccination With Either DTaP-IPV-Hep B-PRP~T Vaccine or Infanrix Hexa Vaccine.

    Anti-Diphtheria antibodies were measured by a toxin neutralization test. Anti-Tetanus, anti-PT, and anti-FHA antibodies were measured by ELISA. Anti-Poliovirus types 1, 2, and 3 were measured by neutralization assay. Anti-Hepatitis B antibodies were measured by the commercially available VITROS ECi/ECiQ Immunodiagnostic System. Anti-PRP antibodies were measured using a Farr type radioimmunoassay that used radiolabeled PRP (3H PRP) in the presence of 36Cl (volume marker).

    Day 140 = Primary series; Day 0 = Pre-booster; and Day 30 = Post-booster titers.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing DTaP-IPV-Hep B-PRP~T combined vaccine + Pneumococcal polysaccharide, DTaP-Hep B-IPV // Hib Vaccine + Pneumococcal polysaccharide and DTaP-IPV-Hep B-PRP~T + Pneumococcal polysaccharide vaccine in people with Diphtheria and Tetanus, run by Sanofi Pasteur, a Sanofi Company at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Colombia, Costa Rica. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Jul 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Summary of Diphtheria and Tetanus Post Primary Series Antibodies, Persistence and Booster Response Following Vaccination With Either DTaP-IPV Hep B-PRP T Vaccine or Infanrix Hexa Vaccine (time frame: Day 140 (Primary series) and Day 0 (Pre-booster)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jul 2014.
