A Phase 3, Randomized, Double-blind, Active Comparator-controlled, Multicenter Clinical Study to Evaluate the Safety, Tolerability, and Immunogenicity of V114 in Recipients of Allogeneic Hematopoietic Stem Cell Transplant (PNEU-STEM)

Purpose

Brief Summary:
This study is designed 1) to describe the safety, tolerability, and immunogenicity of V114 and Prevnar 13™ in pneumococcal vaccine-naïve adult and pediatric recipients of allogeneic hematopoietic stem cell transplant (HSCT), and 2) to describe the safety and tolerability of PNEUMOVAX™23 when administered 12 months after HSCT.

Inclusion Criteria:
    •    Received a human leukocyte antigen (HLA) compatible donor including haploidentical and mismatched (related or unrelated) first allogeneic HSCT (i.e., bone marrow or peripheral blood stem cell) 90 to 180 days prior to randomization.
    •    Received the allogeneic HSCT for acute lymphoblastic leukemia (ALL) in first or second remission, acute myeloid leukemia (AML) in first or second remission, chronic myeloid leukemia (CML) in first chronic or accelerated phase, Hodgkin's lymphoma, non-Hodgkin's lymphoma, myelodysplastic syndrome (MDS), myelofibrosis and myeloproliferative diseases, and non-malignant disease such as aplastic anemia or sickle cell disease in participants ≥18 years of age and any non-malignant disease for participants 3 to <18 years of age.
    •    Life expectancy >12 months after allogeneic HSCT, according to investigator judgement.
    •    Clinically stable engraftment according to investigator judgment.
    •    A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least 1 of the following conditions applies: a) not a woman of childbearing potential (WOCBP) OR b) a WOCBP who agrees to use acceptable contraceptive methods during the treatment period and for at least 6 weeks after the last dose of study intervention.
