What is being measured

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

  1. Number of Subjects With Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations Above the Cut-offs

    The antibody concentrations cut-offs assessed were: equal to or above (≥) 0.1 international units per milliliter (IU/mL) and ≥ 1 IU/mL.

    Measured: At Month 0

  2. Number of Subjects With Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations Above the Cut-offs

    The antibody concentrations cut-offs assessed were: equal to or above (≥) 0.1 international units per milliliter (IU/mL) and ≥ 1 IU/mL.

    Measured: At Month 1

Secondary outcomes (8)
  1. Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations

    Concentrations are presented as international units per millilitre (IU/mL).

    Measured: At Month 0 (PRE) and Month 1 (POST)

  2. Number of Seropositive Subjects for Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN)

    A seropositive subject was defined as a subject with anti-PT, anti-FHA and anti-PRN antibody concentrations ≥ 5 ELISA unit per milli-liter (EL.U/ml)

    Measured: At Month 0 (PRE) and Month 1 (POST)

  3. Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN) Antibody Concentrations

    Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per millilitre (EL.U/mL).

    Measured: At Month 0 (PRE) and Month 1 (POST)

  4. Number of Subjects With Booster Response to Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN)

    Booster response was defined as appearance of antibodies in subjects who were seronegative at the pre-vaccination time point (i.e. with concentrations < 5 El.U/mL) or at least 2-fold increase of prevaccination antibody concentrations in subjects who were seropositive at the pre-vaccination time point (i.e. with concentrations ≥5 El.U/mL.

    Measured: At Month 1

  5. Number of Subjects With Any and Grade 3 Solicited Local Symptoms

    Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site.

    Measured: During the 4-day (Day 0-3) follow-up period after booster vaccination

  6. Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms

    Assessed solicited general symptoms were fatigue, fever [defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)], headache and gastrointestinal symptoms. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.

    Measured: During the 4-day (Day 0-3) follow-up period after booster vaccination

  7. 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.

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

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

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

    Measured: For safety assessment Boostrix I Group and Boostrix II Group were pooled (Pooled Group)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Boostrix TM in people with Acellular Pertussis and Tetanus, run by GlaxoSmithKline at 1 site in Finland.

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 6 inclusion and 19 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 1 site in Finland. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 30 Mar 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 Anti-diphtheria (Anti-DT) and Anti-tetanus Toxoids (Anti-TT) Antibody Concentrations Above the Cut-offs (time frame: At Month 0). The study lists 2 primary outcomes in all. 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 NCT00610168, which also lists 7 linked publications.

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.
