Safety, tolerability, and immunogenicity of V114 pneumococcal vaccine compared with PCV13 in a 2+1 regimen in healthy infants: A phase III study (PNEU-PED-EU-2).
Summary
The purpose of this clinical study is to evaluate the safety and immunogenicity of a 3-dose schedule (2-dose primary series followed by a toddler dose) of pneumococcal conjugate vaccine (PCV) as one of the currently recommended schedules by the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) on Immunizations and practiced in many countries.
The primary hypotheses are that V114 is non-inferior to Prevenar 13™ for the 13 shared serotypes based on response rates and on anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) geometric mean concentrations (GMCs) at 30 days following Dose 3; that V114 is superior to Prevenar 13™ for the 2 serotypes unique to V114 based on the response rates and on anti-PnPs serotype-specific IgG GMCs at 30 days following Dose 3; and that Vaxelis™ administered concomitantly with V114 is non-inferior to Vaxelis™ administered concomitantly with Prevenar 13™ at 30 days following Dose 3 for each antigen included in Vaxelis™.

- Has, or his/her mother has, a documented hepatitis B surface antigen - positive test.
- Has known or history of functional or anatomic asplenia.
- Has failure to thrive based on the clinical judgement of the investigator.
- Has a bleeding disorder contraindicating intramuscular vaccination.
- Has a history of autoimmune disease (including but not limited to systemic lupus erythematosus, antiphospholipid syndrome, Behcet's disease, autoimmune thyroid disease, polymyositis and dermatomyositis, scleroderma, type 1 diabetes mellitus, or other autoimmune disorders).
