Design outcomes

Primary

MeasureTime frame
Main Objective: - To describe the percentage of subjects with anti-HBs concentration = 10 mIU/mL approximately 4 years after completion of a 3+1 schedule - To describe the percentage of subjects with anti-HBs concentration = 10 mIU/mL approximately 4 years after completion of a 2+1 schedule - To describe the percentage of subjects with anti-PT (Pertussis Toxin), anti FHA (Filamentous Hemagglutinin), anti-PRN (Pertactin) and anti-FIM (Fimbriae 2&3) concentration = LLOQ*, = 2 × LLOQ*, and = 4 × LLOQ*, 3 to 4 years after completion of a 2+1 schedule. * Lower Limit of Quantification (LLOQ) = 4 EU/mL for PT, PRN, FIM; LLOQ = 3 EU/mL for FHA;Secondary Objective: - To describe the anti-HBs levels in terms of geometric mean concentration (GMC) approximately 4 years after completion of a 3+1 schedule. - To describe the anti-HBs levels in terms of geometric mean concentration (GMC) approximately 4 years after completion of a 2+1 schedule - To describe the pertussis antibody levels in terms of GMC at 3 to 4 years after completion of a 2+1 schedule.;Primary end point(s): - The percentage of subjects with anti-HBs concentration = 10 mIU/mL - The percentages of subjects with anti-PT, anti-FHA, anti-PRN and anti FIM concentration = LLOQ*, = 2× LLOQ*, and = 4 × LLOQ* * Lower Limit of Quantification (LLOQ) = 4 EU/mL for PT, PRN, FIM; LLOQ = 3 EU/mL for FHA ;Timepoint(s) of evaluation of this end point: Approximately 4 years after completion of a primary series and toodler dose schedule with VAXELIS® or INFANRIX® hexa

Secondary

MeasureTime frame
