Registered outcomes10

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryNumber of Subjects With Antibody Concentration Against Vaccine Antigens, Above a Protocol Defined Cut-off ValueOne month after vaccination.
Antibodies against vaccine antigens assessed were: anti-diphtheria (anti-D) and anti-tetanus (anti-T). Anti-D antibody cut-off value assessed was ≥ 0.1 International Unit per milliliter (IU/mL) Anti-T antibody cut-off values assessed were ≥ 0.1 IU/mL and ≥ 1.0 IU/mL
PrimaryAnti-pertussis Toxoid (PT), Anti-filamentous Haemagglutinin (FHA) and Anti-pertactin (PRN) Antibodies ConcentrationBefore (PRE) and one month after vaccination (POST)Concentration for anti-PT, anti-FHA and anti-PRN antibodies given as geometric mean concentration (GMC) in Enzyme-Linked Immuno Sorbent Assay (ELISA) units per millilitre (EL.U/mL)
SecondaryAnti-T and Anti-D Antibody ConcentrationsBefore (PRE) and one month after vaccination (POST)Concentrations for anti-T and anti-D antibodies given as GMC in IU/mL.
SecondaryNumber of Subjects With Vaccine Response for Anti-T and Anti-D Antibodies Concentrations Above the Cut-offOne month after vaccination
Booster response defined as : For initially seronegative subjects (\< 0.1 IU/mL), antibody concentration ≥ 0.4 IU/mL one month after vaccination. For initially seropositive subjects (≥ 0.1 IU/mL): antibody concentration one month after vaccination ≥ 4 fold the pre-vaccination antibody concentration.
SecondaryNumber of Subjects With Vaccine Response for Anti-PT, Anti-FHA and Anti-PRN Antibodies Concentrations Above the Cut-offOne month after vaccination
Booster response defined as : For initially seronegative subjects (\< 5 EL.U/mL), antibody concentration ≥ 20 EL.U/mL one month after vaccination. For initially seropositive subjects (≥ 5 EL.U/mL) with pre-vaccination antibody concentration \< 20 EL.U/mL: antibody concentration one month after vaccination ≥ 4 fold the pre-vaccination antibody concentration. For initially seropositive subjects (≥ 5 EL.U/mL) with pre-vaccination antibody concentration ≥ 20 EL.U/mL : antibody concentration one month after vaccination ≥ 2 fold the pre-vaccination antibody concentration.
SecondaryNumber of Subjects With Vaccine Response for Anti-PT, Anti-FHA and Anti-PRN Antibodies Concentrations Above the Cut-off, Using Alternative Definitions.One month after vaccination
Vaccine response using alternative definitions defined as: For initially seronegative subjects (\< 5 EL.U/mL ), antibody concentration ≥ 10 EL.U/mL one month after vaccination. For initially seropositive subjects (≥ 5 EL.U/mL), antibody concentration one month after vaccination ≥ 2 fold the pre-vaccination antibody concentration.
SecondaryNumber of Subjects Reporting Solicited Local SymptomsWithin the 4-day (Day 0-3) post-vaccination periodSolicited local symptoms assessed include pain, redness and swelling.
SecondaryNumber of Subjects Reporting Solicited General SymptomsWithin the 4-day (Day 0-3) post-vaccination periodSolicited general symptoms assessed include fatigue, gastrointestinal symptoms, headache, and fever
SecondaryNumber of Subjects Reporting Unsolicited Adverse Events (AE)Within the 31-day (Day 0-30) post-vaccination periodAn AE is 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.
SecondaryNumber of Subjects Reporting Serious Adverse Events (SAE)From the vaccination up to Day 182
An SAE is any untoward medical occurrence that: results in death, is lifethreatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above.
