What is being measured

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

  1. Immunogenicity with respect to components of the study vaccines (in subjects receiving the dTpa vaccine and Tedivax-Adult™/ Td-Rix™)

    Measured: One month after the booster dose (Month 1)

Secondary outcomes (11)
  1. Immunogenicity with respect to components of the study vaccines (in subjects receiving the dTpa, pa vaccines and Tedivax-Adult™/ Td-Rix™)

    Measured: One month after the booster dose (Month 1)

  2. Occurrence of solicited local adverse experiences

    Measured: During the 15-day (Day 0-14) follow-up period after vaccination

  3. Occurrence of solicited general adverse experiences

    Measured: During the 15-day (Day 0-14) follow-up period after vaccination

  4. Occurrence of unsolicited symptoms

    Measured: Within the 31-day (Day 0 -30) follow-up period after vaccination

  5. Occurrence of any serious adverse experiences

    Measured: Within the 31-day (Day 0 -30) follow-up period after vaccination

  6. Lymphoproliferation specific for pertussis toxoid, filamentous haemagglutinin and pertactin/ Cell mediated immunity response

    Measured: At pre-vaccination (Day 0) and Month 1 post-vaccination

  7. Immunogenicity with respect to components of the study vaccines (in subjects who did not respond to diphtheria or tetanus toxoid after the first booster dose)

    Measured: One month after the second and third booster dose (Month 12)

  8. Occurrence of solicited local adverse experiences (in subjects who did not respond to diphtheria or tetanus toxoid after the first booster dose)

    Measured: During the 15-day (Day 0-14) follow-up period after the second and third vaccine dose

  9. Occurrence of solicited general adverse experiences (in subjects who did not respond to diphtheria or tetanus toxoid after the first booster dose)

    Measured: During the 15-day (Day 0-14) follow-up period after the second and third vaccine dose

  10. Occurrenceof unsolicited symptoms (in subjects who did not respond to diphtheria or tetanus toxoid after the first booster dose)

    Measured: Within the 31-day (Day 0 -30) follow-up period after vaccination after the second and third vaccine dose

  11. Occurrence of any serious adverse experiences (in subjects who did not respond to diphtheria or tetanus toxoid after the first booster dose)

    Measured: Within the 31-day (Day 0 -30) follow-up period after vaccination after the second and third vaccine dose

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing GSK Biologicals' reduced-antigen-content diphtheria-tetanus-acellular pertussis vaccine, GSK Biologicals' reduced-antigen-content acellular pertussis vaccine and Tedivax-Adult™/ Td-Rix™ in people with Diphteria, Tetanus and Pertussis, run by GlaxoSmithKline.

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 24 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 17 Dec 2010. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Immunogenicity with respect to components of the study vaccines (in subjects receiving the dTpa vaccine and Tedivax-Adult™/ Td-Rix™) (time frame: One month after the booster dose (Month 1)). 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 NCT01262924, 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 17 Dec 2010.
