Study to Evaluate 13 Valent Pneumococcal Conjugate Vaccine (13vPnC) Vaccine Followed by 23-valent Pneumococcal Polysaccharide Vaccine (23vPS) Vaccine in Allogeneic Hematopoietic Stem Cell Transplant Recipients

Phase 3

Completed

Conditions: Vaccines, Pneumococcal Conjugate Vaccine

Registration Number: NCT00980655

Lead Sponsor: Pfizer

Brief Summary: People who have received an allogeneic hematopoetic stem cell transplant (HSCT) are more likely than other people to get ill from a germ called Streptococcus pneumoniae. Most people who have had a stem cell transplant are offered a vaccine called 23-valent pneumococcal polysaccharide vaccine (23vPS) to help protect against this germ. The purpose of this study is to evaluate the immune response in HSCT recipients who receive a 13 valent pneumococcal vaccine (13vPnC) followed by 23vPS.

Primary Outcome Measures

Name	Time	Method
Geometric Mean Fold Rise (GMFR) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody From Before 13vPnC Dose 1 to 1 Month After 13vPnC Dose 3 in All Participants	Before 13vPnC Dose 1 (pre-vaccination), 1 month after 13vPnC Dose 3	GMFR for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from before 13vPnC Dose 1 to 1 month after 13vPnC Dose 3 were computed using the logarithmically transformed assay results. Confidence interval (CI) for GMFR were back transformations of a CI based on the Student t distribution for the mean logarithm of the mean fold rise. GMFRs were calculated using all participants with available data from both before 13vPnC Dose 1 and after 13vPnC Dose 3 blood draws.
