Hepatitis B Clinical Trial
Official title:
Immunogenicity Study of a DTaP IPV Hep B PRP T Combined Vaccine in Comparison to Infanrix Hexa™, Both Concomitantly Administered With Prevnar™ at 2, 4, and 6 Months of Age in Thai Infants

Is FDA regulated | No |
Health authority | Thailand: Food and Drug Administration |
Study type | Interventional |
The purpose of the study is to provide immunogenicity and safety data of the investigational
hexavalent vaccine when it is given concomitantly (the same day at separate injection sites)
with Prevnar, according to the 2-4-6 month immunization schedule, following one dose of HB
vaccine at birth.
Primary Objective:
To demonstrate that the hexavalent DTaP-IPV-HB-PRP~T combined vaccine induces an immune
response that is at least as good as the response following Infanrix™-Hexa in terms of
seroprotection rates to HB and PRP, one month after a 3 dose primary series (2, 4, and 6
months), when co-administered with Prevnar®
Secondary Objectives:
Immunogenicity:
To describe in each group the immunogenicity parameters to each vaccine component (for
DTaP-IPV-HB-PRP~T and Infanrix™-Hexa) one month after the third dose of the primary series.
Safety:
To describe the overall safety after each injection.

---|---|---|---|---|
Primary | Number of Participants Achieving Seroprotection Against Hepatitis B and Haemophilus Influenzae Type b Post-vaccination With Either DTaP-IPV-Hep B-PRP~T + Prevnar™ or Infanrix Hexa™ + Prevnar™ | Anti-Hepatitis B antibodies were measured using chemiluminescence detection technology; seroprotection was defined as a titer = 10 mIU/mL. Anti-Haemophilus influenzae type b (anti-PRP) antibodies were measured by radioimmunoassay; seroprotection was defined as a titer = 0.15 µg/mL. | Day 150 post-dose 1 | No |
Secondary | Number of Participants With Seroprotection Against Diphtheria and Tetanus Post-vaccination With Either DTaP-IPV-Hep B-PRP~T + Prevnar™ or Infanrix Hexa™ + Prevnar™ | Anti-Diphtheria antibodies were measured by a toxin neutralization test. Anti-Tetanus antibodies were measured by an indirect enzyme-linked immunosorbent assay (ELISA). Seroprotection was defined for both as a titer = 0.01 IU/mL. | Day 150 post-dose 1 | No |
Secondary | Number of Participants With Seroprotection Against Poliovirus Types 1, 2, and 3 Post-vaccination With Either DTaP-IPV-Hep B-PRP~T + Prevnar™ or Infanrix Hexa™ + Prevnar™ | Anti poliovirus types 1, 2, and 3 antibodies were measured by neutralization assay. Seroprotection was defined as a titer = 8 1/dil | Day 150 post-dose 1 | No |
Secondary | Number of Participants With Seroconversion Against Pertussis Post-vaccination With Either DTaP-IPV-Hep B-PRP~T + Prevnar™ or Infanrix Hexa™ + Prevnar™ | Anti pertussis toxoid (PT) and anti-filamentous hemagglutinin (FHA) antibodies were measured by enzyme linked immunosorbent assay (ELISA). Seroconversion was defined as = 4 fold increase over baseline. | Day 150 post-dose 1 | No |
Secondary | Geometric Mean Titers (GMTs) of Vaccine Antibodies Post-vaccination With Either DTaP-IPV-Hep B-PRP~T + Prevnar™ or Infanrix Hexa™ + Prevnar™ | Anti-hepatitis B antibodies were measured using chemiluminescence detection technology. Anti-Haemophilus influenzae type b (anti-PRP) antibodies were measured by radioimmunoassay, anti-Diphtheria by toxin neutralization assay, anti-Tetanus and anti-Pertussis by enzyme-linked immunosorbent assay (ELISA), and anti-Polio by neutralization assay. | Day 150 post-dose 1 | No |
Secondary | Number of Participants Reporting Solicited Injection Site and Systemic Reactions Post-vaccination With Either DTaP-IPV-Hep B-PRP~T + Prevnar™ or Infanrix Hexa™ + Prevnar™ | Solicited Injection Site Reactions: Pain, Erythema, and Swelling. Solicited Systemic Reactions: Pyrexia, Vomiting, Crying, Somnolence, Anorexia, and Irritability Grade 3: Pain, cries when injected limb is moved or the movement of the injected limb is reduced; Erythema and Swelling, =5 cm. Grade 3: Pyrexia, >39°C; Vomiting, =6 episodes per 24 hours or requiring parenteral hydration; Crying, >3 hours; Somnolence, Sleeping most of the time or difficult to wake up; Anorexia, Refuses =3 feeds/meals or refuses most feeds/meals; and Irritability, Inconsolable. |
