About this study

Official title: Assess Immune Persistence & Memory by Giving Plain PRP,PSA & PSC (10 Mths Age), & Immunogenicity & Safety of a Tritanrix™-HBV/Hib-MenAC/ Tritanrix™-HBV/Hib2.5 Booster (15-18 Mths Age) in Previously Primed Subjects

The purpose of the study is as follows:

  • To evaluate the persistence of antibodies and the presence of immune memory induced by a 3-dose primary vaccination with Tritanrix™-HepB/Hib-MenAC (three formulations) in the study DTPwHB/HibMenACTT001 (CPMS No. 759346/001) by giving unconjugated PRP, PSA and PSC at 10 months age to one subset of subjects.
  • To evaluate the persistence of all antibodies pertaining to primary vaccination and the booster response to Tritanrix™-HepB/Hib2.5 vaccine or Tritanrix™-HepB/Hib-MenAC vaccine at 15-18 months age in the other subset of subjects.
Read the detailed description

This study will be conducted in two stages:

At 10 months age, half of the subjects will receive a dose of plain meningococcal AC and PRP polysaccharide (PS) vaccine at 10 months age.

At 15 to 18 months age (DTP booster phase), all subjects will receive a booster dose of Tritanrix™-HepB/Hib-MenAC or Tritanrix™-HepB/Hib2.5.

Being tested
DTPw-HBV/Hib-MenAC conjugate vaccine
Medical subject headings
Haemophilus Infections, Tetanus, Hepatitis B, Diphtheria

  • DTPw-HBV/Hib-MenAC conjugate vaccineBiological

What is being measured

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

  1. Pre & 1M post-plain PS, antibody levels & bactericidal titers (meningococcal serogroups A & C). Pre & 1M post-DTP booster, antibody levels for all vaccine antigens.

Secondary outcomes (1)
  1. Pre & 1M post-DTP booster (subset of subjects), antibody levels for all vaccine antigens. Retrospective serious adverse events (SAEs). Solicited (day 0-7), unsolicited events (day 0-30). SAEs (entire study)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing DTPw-HBV/Hib-MenAC conjugate vaccine in people with Haemophilus Influenzae Type b and Tetanus, run by GlaxoSmithKline at 1 site in Philippines.

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 1 inclusion and 6 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 9 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Philippines. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Pre & 1M post-plain PS, antibody levels & bactericidal titers (meningococcal serogroups A & C). Pre & 1M post-DTP booster, antibody levels for all vaccine antigens.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00317174, which also lists 1 linked publication.

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 9 Sep 2016; AzTrials last refreshed its copy on 26 Oct 2026.
