Antibody Persistence at Age 3.5 and 4.5 Years After Primary and Booster DTaP-IPV-Hep B-PRP~T or Infanrix Hexa Vaccination

January 4, 2016 updated by: Sanofi Pasteur, a Sanofi Company

Evaluation of Antibody Persistence at 3.5 and 4.5 Years of Age in Healthy Children After Primary Series and Booster Vaccination With Investigational (DTaP-IPV-Hep B-PRP~T) or Infanrix Hexa™ Vaccines in Latin America

This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722) and booster vaccination in Study A3L27 (NCT01444781).

Study Objective:

  • To describe the long-term antibody persistence at 3.5 and 4.5 years of age following a 3-dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) +Rotarix™ or Infanrix hexa™+Prevenar™ (PCV7) +Rotarix™ vaccination at 2, 4, 6 months of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) or Infanrix hexa™+Prevenar™ (PCV7) at 12 to 24 months of age.

Observational Objectives:

  • To describe the long-term antibody persistence by group and by stratification on the age at inclusion of the A3L27 booster study.
  • To describe the effect of one additional oral dose of stand alone poliovirus isotypes 1, 2 and 3 vaccine* on the antibody persistence immune response for poliovirus isotypes (4 vs 5 doses of poliovirus administered).

Study Overview

Detailed Description

No investigational vaccine will be administered in the study. Subjects who were previously randomized and completed the primary series, Study A3L24 and the booster study A3L27 will be invited to take part in this study.

Any serious adverse events (SAEs) related to the vaccines administered during the preceding trial (A3L27;) and SAEs related to A3L28 study procedures will be collected throughout the trial.

No vaccine will be administered as part of this study.

Description

Inclusion Criteria:

  • Aged 3 years and a half (42 months ± 60 days) on the day of the first study visit
  • Informed consent form has been signed and dated by the parent(s) or other legally acceptable representative (and by independent witness/es if required by local regulations)
  • Subject and parent/legally acceptable representative are able to attend all scheduled visits and to comply with all trial procedures
  • Receipt of primary vaccination with 3 doses of investigational vaccines during the primary series trial A3L24 (either DTaP-IPV-Hep B-PRP-T or Infanrix hexa, concomitantly administered with Prevenar [PCV7] and Rotarix) and a booster dose during the trial A3L27 (either DTaP-IPV-Hep B-PRP-T or Infanrix hexa, concomitantly administered with Prevenar [PCV7]).

Exclusion Criteria:

  • Participation at the time of study enrollment (or in the 4 weeks preceding the first trial visit) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
  • Incomplete primary and booster immunization at trial A3L24 and A3L27
  • Receipt of any vaccine in the 4 weeks preceding the first trial visit or planned receipt of any vaccine in the 4 weeks preceding the second trial visit
  • Previous vaccination against diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Haemophilus influenzae type b infections with other vaccine(s) after completion of A3L27 study
  • Receipt of immune globulins, blood or blood-derived products in the past 3 months
  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 3 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
  • History of diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Haemophilus influenzae type b infection(s), confirmed either clinically, serologically, or microbiologically after completion of trial A3L27
  • Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating blood drawn
  • Acute or chronic illness that, in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion.
