Clinical Trial

Polyvalent Pneumococcal Conjugate Vaccine

Study Description

A Phase 1/Phase 2 Study of Polyvalent Pneumococcal Conjugate Vaccine (pPCV) in Adults

This Phase 1 and Phase 2 study will evaluate the safety, tolerability and immunogenicity of pPCV when administered to adults. Phase 1 has no formal hypothesis. The primary hypotheses for Phase 2 are: pPCV is noninferior to Pneumovaxa"c23 as measured by the serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) for the common serotypes at 30 days postvaccination and that the serotype-specific OPA GMTs for the unique serotypes in pPCV at 30 days postvaccination are statistically significantly greater following vaccination with pPCV than those following vaccination with Pneumovaxa"c23.
