About this study

Official title: Booster Vaccination Study to Assess Immunogenicity & Safety of a Dose of GSK Biologicals' Mencevax™ ACWY & 1/5th of a Dose of Mencevax™ ACWY in Subjects Primed in the DTPW-HBV=HIB-MENAC-TT-011 Study

This study will be conducted in three stages. In the DTP booster stage at 15 to 24 months of age, all subjects will receive a booster dose of Tritanrix™-HepB/Hiberix™. In the Mencevax™ ACWY "full dose" stage at 24 to 30 months of age all subjects will receive a dose of Mencevax™ ACWY. In the Mencevax™ ACWY "small dose" stage at 30 to 36 months of age, the first 75 subjects in each of the two centers will be tested for boostability of the MenA and MenC immune response by giving a fifth of a dose of a Mencevax™ ACWY vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Read the detailed description

Subjects in the group that was previously primed with Tritanrix™-HepB/Hiberix™ will be the control group for the group that was previously primed with Tritanrix™-HepB/Hib-MenAC.

Blood samples will be drawn from subjects as follows:

  • prior to and one month after the full dose of the Mencevax™ ACWY vaccine.

What is being measured

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

  1. Number of Subjects With Serum Bactericidal Activity Against Neisseria Meningitidis Serogroups A, C (rSBA-MenA, C) Using Rabbit Complement Antibodies

    Antibody cut-offs were higher than or equal to (≥) 1:128

    Measured: 1 month after Mencevax ACWY vaccination (at 25 to 31 months of age).

Secondary outcomes (11)
  1. Number of Subjects With Anti-rSBA-MenA, C Antibody Titers ≥ Pre-defined Cut-off Values

    Pre-defined cut-offs were ≥ 1:8 and ≥ 1:128

    Measured: Prior to (at 24 to 30 months of age) and after (at 25 to 31 months of age) Mencevax ACWY vaccination.

  2. Anti-rSBA-MenA, C Antibody Titers

    Antibody titers were expressed as Geometric Mean Titers (GMTs)

    Measured: Prior to (at 24 to 30 months of age) and after (at 25 to 31 months of age) Mencevax ACWY vaccination.

  3. Number of Subjects With Anti-pilysaccharide A and C (Anti-PSA/PSC) Antibody Concentrations ≥ Predefined Cut-off Values

    Antibody cut-offs were ≥ 0.3, 2 micrograms per millilitre (µg/mL).

    Measured: Prior to (at 24 to 30 months of age) and after (at 25 to 31 months of age) Mencevax ACWY vaccination.

  4. Anti-PSA, Anti-PSC Antibody Concentrations

    Antibody concentrations were expressed as Geometric Mean Concentrations (GMCs).

    Measured: Prior to (at 24 to 30 months of age) and after (at 25 to 31 months of age) Mencevax ACWY vaccination.

  5. Number of Subjects With Anti-hepatitis B Surface (Anti-HBs) Antigen Antibody Concentrations ≥ Cut-offs

    The antibody concentrations cut-off was ≥ 10 milli international units per millilitre (mIU/mL).

    Measured: Prior to the Mencevax ACWY vaccination at 24-30 Months of age

  6. Anti-HBs Concentrations

    Antibody concnetrations were expressed as Geometric Mean Concentrations (GMCs).

    Measured: Prior to the Mencevax ACWY vaccination at 24-30 Months of age

  7. Number of Subjects With Vaccine Response for rSBA-Men A, C

    Vaccine response was defined as follows: for initially seronegative subjects (i.e. with rSBA titer < 1:8 pre-vaccination), rSBA titer ≥ 1:32 post-vaccination (seroconversion), and for initially seropositive subjects (i.e. with rSBA > 1:8 prevaccination), at least a 4-fold increase in rSBA titer from pre-vaccination to post-vaccination.

    Measured: 1 month after Mencevax ACWY vaccination (at 25 to 31 months of age).

  8. Number of Subjects With Solicited Local Symptoms

    Assessed solicited local symptoms were pain, redness, swelling. Any = symptom occurring regardless of intensity grade.

    Measured: During the 4-day follow-up period after the Mencevax ACWY vaccination, at 24-30 months of age

  9. Number of Subjects With Solicited General Symptoms

    Assessed solicited general symptoms were drowsiness, irritability, loss of appetite, rectal fever [≥ 38 degrees Celsius (°C)]. Any = occurrence of symptom regardless of intensity grade.

    Measured: During the 4-day follow-up period after the Mencevax ACWY vaccination, at 24-30 months of age

  10. Number of Subjects With 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 is defined as the occurrence of any unsolicited AE regard-less of intensity grade or relation to vaccination.

    Measured: From Day 0 at months 15-24 of age to study end at Months 25-31 of age

  11. Number of Subjects With Serious Adverse Events (SAEs)

    SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

    Measured: From 15-24 Months of age up to Months 25-31 of age

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tritanrix™- HepB, Hiberix™ and Mencevax™ ACWY in people with Infections, Meningococcal, run by GlaxoSmithKline at 2 sites 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 5 inclusion and 13 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 6 Jun 2018. 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 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 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 3 Aug 2017). 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?

Number of Subjects With Serum Bactericidal Activity Against Neisseria Meningitidis Serogroups A, C (rSBA-MenA, C) Using Rabbit Complement Antibodies (time frame: 1 month after Mencevax ACWY vaccination (at 25 to 31 months of age).). 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 6 Jun 2018.
