NCT ID: NCT00489970

Last Updated: 2020-05-01

Results Overview

Recruitment status

COMPLETED

Study phase

PHASE3

Target enrollment

1954 participants

Primary outcome timeframe

At year 1 after the vaccination in primary study (NCT00346073)

Participant Flow

A total of 1592 participants were enrolled in the study at Year 1 (in the Boostrix and Adacel groups). As per advice from the Centre for Biologics and Research Evaluation (CBER), an additional treatment group acting as control was also added at Year 9, therefore the total number of subjects analyzed was 1592 (Year 1) + 362 (Year 9) = 1954.

Subjects who received a single dose of Boostrix or Adacel vaccines, in the primary study (NCT00346073) were included in this study.

Alternative Booster response to D and T antigens is defined as: - For subjects with pre-booster antibody concentration below 0.1 IU/mL: antibody concentrations at least four times the 0.1IU/ML, one month after vaccination, and - For subjects with pre-booster antibody concentration ≥0.1 IU/mL and \<1.0 IU/mL: antibody concentrations of at least four times the pre-booster antibody concentration, one month after vaccination. - For subjects with pre-booster antibody concentration ≥1.0 IU/mL and \<6.0 IU/mL: antibody concentrations of at least two times the pre-booster antibody concentration, one month after vaccination. - Subjects with pre-booster antibody concentration ≥6.0 IU/mL are not evaluable for booster response. S- = Antibody concentration \< 0.1 IU/mL S+ = Antibody concentration ≥ 0.1 IU/mL Total = subjects either seropositive or seronegative
