Study of DTaP-IPV-Hep B-PRP~T Combined Vaccine in Indian Infants Previously Given a Dose of Hepatitis B Vaccine at Birth

Phase 3
Completed
Conditions
Whooping Cough
Poliomyelitis
Hepatitis B
Diphtheria
Tetanus
Invasive Hib Infections
Registration Number
NCT01948193
Lead Sponsor
Sanofi Pasteur, a Sanofi Company
Brief Summary

The purpose of this study is to describe the immunogenicity and safety of a novel DTaP- IPV- Hep B-PRT\~T fully liquid combined hexavalent vaccine (Hexaxim™) administered at 6, 10 and 14 weeks of age in infants born to mothers documented to be serum anti-hepatitis B surface antigen (HBsAg) serology negative in India.

Primary Objective:

* To evaluate the immunogenicity of the study vaccine in terms of seroprotection \[diphtheria toxoid, tetanus toxoid, poliovirus types 1, 2 and 3, Haemophilus influenzae type b (Hib) polysaccharide (PRP), hepatitis B (Hep B)\] and vaccine response for pertussis antigens \[pertussis toxoid (PT) and filamentous haemagglutinin (FHA)\] one month after the third dose.

Secondary Objectives:

* To further describe the immunogenicity of the study vaccine, before the first dose and one month after the third dose.

* To describe the safety after each and any doses of the study vaccine.

Detailed Description

All participants will receive a total 4 doses of Hep B, i.e. one dose of Hep B monovalent vaccine given at birth followed by 3 doses of Sanofi Pasteur's hexavalent vaccine given at 6, 10 and 14 weeks of age in the context of the study. Participants and parents will attend four clinic visits; the expected participation in the study is approximately 3 months.

  • Previous vaccination against the diphtheria, tetanus, pertussis, poliomyelitis (expect the birth dose of OPV as per national recommendations) and hepatitis B (except the birth dose of Hep B vaccine) diseases or Hib infection with the trial vaccine or another vaccine
  • Past or current receipt of immune globulins, blood or blood-derived products or planned administration during the trial
  • Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy since birth; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks since birth)
  • History of diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, or Hib infections (confirmed either clinically, serologically or microbiologically)

  • Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination
  • In an emergency setting, or hospitalized involuntarily
  • Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion
  • Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (axillary temperature ≥38°C) on the day of inclusion (a prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided)
  • Identified as a natural or adopted child of the Investigator, relatives or employee with direct involvement in the proposed study

Percentage of Participants With Seroprotection After Vaccinations With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine Following a Documented Dose of a Commercial Oral Poliovirus Vaccine and Recombinant Hep B Monovalent Vaccine at BirthPre-dose 1 to one month post-dose 3

Diphtheria antibodies were measured by a toxin neutralization test, tetanus antibodies by an enzyme-linked immunosorbent assay (ELISA), Haemophilus influenzae type b polysaccharide (PRP) antibodies by Farr type radioimmunoassay, poliovirus 1, 2, and 3 antibodies by a neutralization assay, and Hepatitis B (Hep B) antibodies were measured by VITROS ECi/ECiQ Immunodiagnostic System.

Description of seroprotection: Diphtheria and Tetanus antibody concentrations ≥0.01 International Units (IU)/mL; Poliovirus 1, 2, and 3 titers ≥8 (1/dilution); Hep B concentrations ≥10 mIU/mL, and PRP ≥0.15 µg/mL.

Percentage of Participants With Vaccine Response After Vaccinations With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine Following a Documented Dose of a Commercial Oral Poliovirus Vaccine and Recombinant Hep B Monovalent Vaccine at BirthPre-dose 1 to one month post-dose 3

Anti-pertussis toxin (PT) and anti-filamentous hemagglutinin (FHA) antibodies were measured with an ELISA. Vaccine response was defined as percentage of participants with post-dose 3 anti-PT and anti-FHA antibody concentrations in ELISA units (EU)/mL ≥ 4 x Lower Limit of Quantification (LLOQ) if pre-vaccination concentration was \< 4 x LLOQ or ≥ pre-vaccination concentration if pre-vaccination concentrations ≥ 4 x LLOQ.
