NCT03891758

Brief Summary

The purpose of this study is to evaluate immunogenicity of BK1310 for all antigens (anti-PRP, diphtheria toxin, pertussis, tetanus toxin, and polio virus), after 3 times of injection, when compared noninferiority with co-administration of ActHIB® and Tetrabik, as well as efficacy and safety, in healthy infants.

Outcome Measures

Primary Outcomes (1)

  • Antibody Prevalence Rate Against Anti-PRP With 1 μg/mL or Higher, Diphtheria Toxin, Pertussis, Tetanus Toxin, and Polio Virus, Defined as the Percentage of Participants With the Antibody Against Anti-PRP

    Antibody prevalence rate is defined as the percentage of participants whose criteria of each antibody titer: Anti-diphtheria antibody concentrations: \>=0.1 IU/mL, Anti-PT antibody concentrations: \>=10.0 EU/mL, Anti-FHA antibody concentrations: \>=10.0 EU/mL, Anti-tetanus antibody concentrations: \>=0.01 IU/mL, Anti-poliovirus serotype 1,2 and 3 antibody titers (fold) \>=8

    4 weeks after the primary immunization (Visit 4)

Secondary Outcomes (14)

  • Anti-PRP Antibody Prevalence Rate With 0.15 μg/mL or Higher, Defined as the Percentage of Participants With the Anti-PRP Antibody

    4weeks after the primary immunization (Visit 4)

  • Geometric Mean Antibody Titer of Anti-PRP Antibody

    4weeks after the primary immunization (Visit 4)

  • Anti-PRP Antibody Prevalence Rate With 1 μg/mL or Higher, Defined as the Percentage of Participants With the Anti-PRP Antibody

    4 weeks after the booster dose (Visit 6)

  • Anti-PRP Antibody Prevalence Rate With 0.15 μg/mL or Higher, Defined as the Percentage of Participants With the Anti-PRP Antibody
