Comparison of DTaP-HB-PRP T Combined Vaccine to Tritanrix-HepB/Hib™, Both Given Concomitantly With Oral Polio Vaccine

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to support the registration of the pentavalent DTaP-HB-PRP T vaccine in countries that follow the World Health Organization-Expanded Program of Immunization (WHO-EPI) schedule. The primary objective is: To demonstrate that the pentavalent DTaP-HB-PRP T combined vaccine does not induce a lower immune response than Tritanrix-HepB/Hib™ in terms of the seroprotection rate to hepatitis B (HB) one month after a 3-dose primary series at 6, 10, and 14 weeks of age. The secondary objectives are: To describe in each group the immunogenicity parameters one month after the 3-dose primary series at 6, 10, and 14 weeks of age; and To evaluate the overall safety in terms of any adverse events in the first 28 days after each injection and any serious adverse events during the entire trial.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Seroprotection to Hepatitis H Antigen After Vaccination With Either DTaP-Hep B-PRP T Concomitantly With Oral Polio Vaccine (OPV) or Tritanrix-Hep B/Hib™ Concomitantly With OPV | Immunogenicity was assessed by means of radioimmunoassay (RIA) for hepatitis B (HBs) antibodies. Seroprotection was defined as titers ≥ 10 mIU/mL at 30 days after the third vaccination. | 1 month post third vaccination | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Anti-Hepatitis B Responses After Vaccination With Either DTaP-Hep B-PRP T Concomitantly With Oral Polio Vaccine (OPV) or Tritanrix-Hep B/Hib™ Concomitantly With OPV | Immunogenicity was assessed by means of radioimmunoassay (RIA) for hepatitis B (HBs) antibodies. Anti-Hepatitis B Responses was defined as titers ≥ 100 mIU/mL at 30 days after the third vaccination. | 1 month post third vaccination | 
| Geometric Mean Titers (GMTs) of Vaccine Antibodies After Vaccination With Either DTaP-Hep B-PRP-T Concomitantly With OPV or Tritanrix-Hep B/Hib™ Concomitantly With OPV | Immunogenicity were assessed by means of enzyme immunoassay (EIA) for antibodies to the vaccine antigens 1 month after the third vaccination (Day 150). | 1 month post third vaccination | 
| Number of Participants With Anti-Diphtheria and Anti-Tetanus Responses After Vaccination With Either DTaP-Hep B-PRP T Concomitantly With Oral Polio Vaccine (OPV) or Tritanrix-Hep B/Hib™ Concomitantly With OPV | Immunogenicity was assessed by means of radioimmunoassay (RIA) for Diphtheria and Tetanus antibodies. Anti-Diphtheria and anti-tetanus Responses were assayed at ≥ 0.01 IU/mL and at ≥ 0.1 IU/mL at 30 days after the third vaccination. | 1 month post third vaccination | 
| Number of Participants With Seroconversion for Anti-Pertussis and Anti-Filamentous Hemagglutinin Antibodies After Vaccination With Either DTaP-Hep B-PRP-T Concomitantly With OPV or Tritanrix-Hep B/Hib™ Concomitantly With OPV | Anti-Pertussis toxoid and Anti-Filamentous Hemagglutinin antibodies were assessed by means of enzyme immunoassay (EIA). Seroconversion was defined as ≥ 4 fold increase in antibody titers from Day 0 to 30 days after the third vaccination. | 1 month post third vaccination | 
| Number of Participants Reporting At Least One Solicited Injection Site and Systemic Reaction Following Each Vaccination With Either DTaP-Hep B-PRP-T Concomitantly With Oral Polio Vaccine (OPV) or Tritanrix-Hep B/Hib™ Concomitantly With OPV | Solicited injection site reactions: Tenderness, Erythema, and Swelling; Systemic reactions: Fever (Temperature), Vomiting, Crying, Somnolence, Anorexia, and Irritability. Grade 3 reactions defined as: Tenderness - cries when injected limb is moved; Erythema and Swelling - ≥ 5cm; Fever - temperature ≥ 39.6ºC; 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. | Day 0 up to Day 7 after each vaccination |
