Immunogenicity Study of Antibody Persistence and Booster Effect of DTaP-HB PRP~T Combined Vaccine in Filipino Infants

July 5, 2016 updated by: Sanofi Pasteur, a Sanofi Company

Immunogenicity Study of the Antibody Persistence and Booster Effect of DTaP-Hep B-PRP-T Combined Vaccine at 12 to 18 Months of Age Following a Primary Series at 6, 10 and 14 Weeks of Age in Healthy Filipino Infants Having Received Hepatitis B Vaccine at Birth

DTaP-HB-PRP~T combined vaccine is being developed in order to comply with expanding programs for immunization in infancy, while offering the benefit of a reduced number of injections, and potentially of an increased acceptance.

Primary Objectives:

  • To describe the antibody persistence at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix-Hep B/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hepatitis B (Hep B) vaccine given at birth.
  • To describe the effect of a booster dose of DTaP-HB-PRP~T on immunogenicity at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix HepB/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hep B vaccine given at birth.

Secondary Objective:

  • To describe the safety profile of the booster dose of the DTaP-HB-PRP~T vaccine when administered concomitantly with Oral Polio Vaccine (OPV).

Detailed Description

This study will assess the immunogenicity and reactogenicity of the investigational DTaP-HB-PRP~T combined vaccine when given as a booster dose, concomitantly with OPV, in Filipino children previously primed at 6, 10, and 14 weeks with the investigational DTaP-HB-PRP~T combined vaccine or Tritanrix-Hep B/Hib™ vaccine and having received a first dose of Hep B vaccine (Recomvax B™) at birth in a previous study, AL201 (NCT00348881).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Antibody Persistence and Immunogenicity Booster Response to Vaccination With DTaP-Hep B-PRP~T Concomitantly With Oral Polio Vaccine (OPV)
Time Frame: Day 0 (pre-vaccination) and Day 28 post-booster vaccination

Immunogenicity was assessed by means of radioimmunoassay (RIA) for anti-Hepatitis B (Hep Bs) and anti-PRP antibodies, enzyme immunoassay (EIA) for anti-Tetanus, and serum neutralization (SN) for anti-Diphtheria.

Booster responses defined as titers ≥ 10 mIU/mL for anti-Hep Bs; ≥ 0.15 μg/mL for anti-PRP; ≥ 0.01 IU/mL for anti-Tetanus and anti-Diphtheria; Pertussis Toxoid and Filamentous Hemagglutinin (FHA) 4-fold increase and booster response.
Day 0 (pre-vaccination) and Day 28 post-booster vaccination

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Geometric Mean Titers (GMTs) of Vaccine Antibodies After Booster Vaccination With DTaP-Hep B-PRP~T Combined Vaccine Concomitantly With Oral Polio Vaccine (OPV)
Time Frame: Day 0 (pre-vaccination) and Day 28 post-vaccination
Immunogenicity was assessed by means of radioimmunoassay (RIA) for anti-Hepatitis B (Hep Bs) and anti-PRP antibodies, enzyme immunoassay (EIA) for anti-Tetanus, and serum neutralization (SN) for anti-Diphtheria following the booster vaccination.
Day 0 (pre-vaccination) and Day 28 post-vaccination
Number of Participants Reporting Solicited Injection Site Reaction or Systemic Reactions Following Vaccination With a Booster Dose of the DTaP-Hep B-PRP~T Combined Vaccine Concomitantly With Oral Polio Vaccine (OPV)
Time Frame: Day 0 up to Day 7 after vaccination

Solicited injection site reactions: Pain, Erythema, and Swelling; Solicited systemic reactions; Pyrexia (temperature), Vomiting, Abnormal Crying, Drowsiness, Loss of Appetite, and irritability.

Grade 3 reactions are defined as: Pain - cries when injected limb is moved; Erythema and Swelling - ≥ 5cm; Fever - rectal temperature ≥ 39.5ºC; Vomiting - ≥6 episodes per 24 hours; Crying - inconsolable crying for >3 hours; Somnolence - sleeping most of the time or difficulty to wake up; Anorexia - refuses ≥3 feeds; and Irritability - inconsolable.
