Persistency Study After aP / Tdap Booster Vaccines in Adult Subjects (V113_01 Extension 1)

The purpose of this study is to evaluate the persistence of immune response against the three pertussis antigens (anti- pertussis toxoid (PT), anti-filamentous hemagglutinin (FHA) and anti-pertactin (PRN)) in subjects who received a booster dose of either aP or Tdap study vaccines or Boostrix® during V113_01 study.

There was only one Clinic Visit at day 1. Eligible subjects went undergo a single blood draw after which they were observed for approximately 15 minutes. Approximately 10.0 mL of blood was withdrawn.

No vaccine was administered and no safety data was collected in this study.

Inclusion criteria

  • Healthy individuals previously enrolled in V113_01 trial, who completed the study following study protocol and who received the appropriate booster vaccine per group assignment

Exclusion criteria

  • Clinical conditions representing a contraindication to blood draw.
  • Abnormal function of the immune system resulting from:
  • Clinical conditions

Treatment and study plan

aP booster

Biological

Acellular pertussis vaccine:

Acellular pertussis (aP) vaccine was administered with different antigen doses intramuscularly in the upper deltoid region of the subject's non-dominant arm.

Biological: Diphtheria and tetanus vaccine (adsorbed, reduced antigen content, Germany) To ensure all subjects receive a tetanus and diphtheria booster vaccination, an injection was administered on Study Day 30, one month after the administration of the investigational vaccine.

TdaP booster

Biological

Tetanus, reduced diphtheria, and acellular pertussis vaccine (adsorbed) Tetanus, reduced diphtheria, and acellular pertussis (TdaP) vaccine was administered with different antigen doses intramuscularly in the upper deltoid region of the subject's non-dominant arm.

Other: Saline solution Subjects received one injection of saline solution at one month after vaccination.

Licensed TdaP booster (Boostrix®)

Biological

Licensed TdaP booster vaccine Licenced TdaP booster vaccine was administered intramuscularly in the upper deltoid region of the subject's non-dominant arm.

Other: Saline solution Subjects received one injection of saline solution at one month after vaccination.

Primary outcomes

  1. Geometric Mean Concentrations (GMCs) of Antibodies in aP1, aP2, aP4 Groups Against Pertussis Antigens at Day 1.

    Time frame: Day 1

    The antibody response against the pertussis antigen components (PT, FHA and PRN) at day 1 as measured by Multiplex ELISA and reported as Geometric Mean Concentrations (GMCs) in aP1, aP2, aP4 Groups versus the response to the commercially available Tdap comparator.

    Note: The mean and confidence intervals of Licensed Tdap for the same antigen can be different (from aP to Tdap table) since two different statistical model were fitted within each antigen: one with aP and Licensed Tdap groups and one with Tdap and Licensed Tdap groups.

  2. Geometric Mean Concentrations (GMCs) of Antibodies in T5D2aP1, T5D2aP2 and T5D2aP4 Groups Against Pertussis Antigens at Day 1.

    Time frame: Day 1

    The antibody response against the pertussis antigen components (PT, FHA and PRN) in serum at day 1 as measured by Multiplex ELISA and reported as Geometric Mean Concentrations (GMCs) in T5D2aP1, T5D2aP2 and T5D2aP4 Groups versus the response to the commercially available Tdap comparator.

    Note: The mean and confidence intervals of Licensed Tdap for the same antigen can be different (from aP to Tdap table) since two different statistical model were fitted within each antigen: one with aP and Licensed Tdap groups and one with Tdap and Licensed Tdap groups.

  3. Geometric Mean Concentrations (GMCs) of Antibodies in T5D4aP1, T5D4aP2 and T5D4aP4 Groups Against Pertussis Antigens at Day 1.

    Time frame: Day 1

    The antibody response against the pertussis antigen components (PT, FHA and PRN) in serum at day 1 as measured by Multiplex ELISA and reported as Geometric Mean Concentrations (GMCs) in T5D4aP1, T5D4aP2 and T5D4aP4 Groups versus the response to the commercially available Tdap comparator.

    Note: The mean and confidence intervals of Licensed Tdap for the same antigen can be different (from aP to Tdap table) since two different statistical model were fitted within each antigen: one with aP and Licensed Tdap groups and one with Tdap and Licensed Tdap groups.

  4. Geometric Mean Ratios Antibodies Concentrations in aP1, aP2, aP4 Groups as Measured at V113_01E1 Day 1 vs. All V113_01 Time Points.

    Time frame: Day 1, Day 8, Day 30, Day 180, Day 365 of V113_01 and Day 1 of V113_01E1

    Geometric Mean Ratios of anti-PT, anti-FHA and anti-PRN antibody were calculated to measure the changes in immunogenicity concentrations within subjects from all V113_01 time points to V113_01E1 day 1.

    Note: The mean and confidence intervals of Licensed Tdap for the same antigen can be different (from aP to Tdap table) since two different statistical model were fitted within each antigen: one with aP and Licensed Tdap groups and one with Tdap and Licensed Tdap groups.

  5. Geometric Mean Ratios Antibodies Concentrations in T5D2aP1, T5D2aP2 and T5D2aP4 Groups as Measured at V113_01E1 Day 1 vs. All V113_01 Time Points.

    Time frame: Day 1, Day 8, Day 30, Day 180, Day 365 of V113_01 and Day 1 of V113_01E1

    Geometric Mean Ratios of anti-PT, anti-FHA and anti-PRN antibody were calculated to measure the changes in immunogenicity concentrations within subjects from all V113_01 time points to V113_01E1 day 1.

    Note: The mean and confidence intervals of Licensed Tdap for the same antigen can be different (from aP to Tdap table) since two different statistical model were fitted within each antigen: one with aP and Licensed Tdap groups and one with Tdap and Licensed Tdap groups.

  6. Geometric Mean Ratios Antibodies Concentrations in T5D4aP1, T5D4aP2 and T5D4aP4 Groups as Measured at V113_01E1 Day 1 vs. All V113_01 Time Points.

    Time frame: Day 1, Day 8, Day 30, Day 180, Day 365 of V113_01 and Day 1 of V113_01E1

    Geometric Mean Ratios of anti-PT, anti-FHA and anti-PRN antibody were calculated to measure the changes in immunogenicity concentrations within subjects from all V113_01 time points to V113_01E1 day 1.

    Note: The mean and confidence intervals of Licensed Tdap for the same antigen can be different (from aP to Tdap table) since two different statistical model were fitted within each antigen: one with aP and Licensed Tdap groups and one with Tdap and Licensed Tdap groups.
