Study Evaluating the Safety, Tolerability and Immunogenicity of 13vPnC as a 2-Dose Regimen or With 23vPS

The objective of this study is to compare the safety, tolerability and immunologic response to a dose of 23vPS or 13vPnC given one year after either 13vPnC or 23vPS in subjects that have never received a previous dose of 23vPS.

Treatment and study plan

13 valent Pneumococcal Conjugate Vaccine

Biological

0.5 ml dose 13vPnC will be administered into the deltoid muscle at year 0 and year 1

23-valent pneumococcal polysaccharide vaccine

Biological

0.5 ml dose 23vPS will be administered into the deltoid muscle at year 0 and 0.5 ml dose 13vPnC at year 1

Primary outcomes

  1. Pneumococcal OPA Geometric Mean Titers (GMTs) for the 12 Common Serotypes for 13vPnC / 23vPS (Year 1) Versus 23vPS (Year 0)

    Time frame: 1 month after vaccination 1 (Vax 1=Day 1/ Year 0 [Visit 1]) and 1 month after vaccination 2 (Vax 2=Day 351 up to Day 379 after Visit 1)

    Antibody geometric mean titers as measured by opsonophagocytic assays (OPA) for 12 common pneumococcal serotypes (serotypes 1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). Confidence intervals (CI) for the GMTs are back transformations of a CI based on the Student t distribution for the mean logarithm of the titers.

  2. Pneumococcal OPA Geometric Mean Titers (GMTs) for the 12 Common Serotypes for 13vPnC / 23vPS Versus 23vPS / 13vPnC (Year 1)

    Time frame: 1 month after vaccination 2 (Vax 2=Day 351 up to Day 379 after Visit 1)

    Antibody geometric mean titers as measured by opsonophagocytic assays (OPA) for 12 common pneumococcal serotypes (serotypes 1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F).
