Study Evaluating The Safety, Tolerability And Immunogenicity Of A 13-Valent Pneumococcal Conjugate Vaccine (13vPnC)
A Phase 3, Randomized, Active-Controlled, Modified Double-Blind Trial, Evaluating The Safety, Tolerability And Immunogenicity Of A 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) Compared To A 23-Valent Pneumococcal Polysaccharide (23vPS) Vaccine in Ambulatory Elderly Individuals Aged 70 Years And Older Who Received One Dose of 23vPS At Least 5 Years Prior To Study Enrollment

Brief Summary
This study will evaluate the safety, tolerability and immunogenicity of study vaccines 13vPnC and 23vPS in older, healthy subjects who have previously received a dose of 23vPS at least 5 years ago. It will also evaluate the safety, tolerability and immunogenicity to a dose of 13vPnC 1 year after the initial dose of study vaccine.

Outcome Measures
Primary Outcomes (2)
Pneumococcal OPA Geometric Mean Titers (GMTs) for the 12 Common Serotypes for 13vPnC Relative to 23vPS (Vax 1 / Year 0)
Antibody geometric mean titers as measured by opsonophagocytic activity (OPA) assays for the 12 common 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.
1 month after Vax 1 / Year 0
Percentage of Participants Achieving a ≥ 4-fold Rise for Serotype 6A OPA Titer for 13vPnC Relative to 23vPS (Vax 1 / Year 0)
OPA titer for the 6A serotype measured for at least a 4-fold increase from the prevaccination to postvaccination blood sample collection. Exact 2-sided CI (Clopper and Pearson) based upon the observed percentage of participants.
Baseline, 1 month after Vax 1 / Year 0
Secondary Outcomes (4)
Pneumococcal OPA Geometric Mean Titer (GMT) for Serotype 6A for 13vPnC Relative to 23vPS (Vax 1 / Year 0)
1 month after Vax 1 / Year 0
Pneumococcal OPA Geometric Mean Titers (GMTs) for the 13 Serotypes for 13vPnC / 13vPnC (Vax 2 / Year 1) Relative to 13vPnC (Vax 1 / Year 0)
1 month after Vax 1 / Year 0, 1 month after Vax 2 / Year 1
Pneumococcal OPA Geometric Mean Titers (GMTs) for the 12 Common Serotypes for 13vPnC / 13vPnC (Vax 2 / Year 1) Relative to 23vPS (Vax 1 / Year 0)
1 month after Vax 1 / Year 0, 1 month after Vax 2 / Year 1
Pneumococcal OPA Geometric Mean Titer (GMT) for Serotype 6A for 13vPnC / 13vPnC (Vax 2 / Year 1) Relative to 23vPS (Vax 1 / Year 0)
1 month after Vax 1 / Year 0, 1 month after Vax 2 / Year 1

Percentage of Participants Reporting Pre-specified Local Reactions Within 14 Days After Vaccination for 13vPnC (Vax 1 / Year 0) and 13vPnC / 13vPnC (Vax 2 / Year 1)
Days 1 through 14 / Year 0, Days 1 through 14 / Year 1
