Abatacept for acute graft-versus-host disease prophylaxis after unrelated donor hematopoietic cell transplantation.

ABSTRACT:

Abstract

Abatacept plus calcineurin inhibitors/methotrexate (CNI/MTX) is the first US Food and Drug Administration (FDA)-approved regimen for acute graft-versus-host disease (aGVHD) prophylaxis during unrelated-donor hematopoietic cell transplantation (URD-HCT). Using Center for International Blood and Marrow Transplant Research data, we investigated its impact in patients receiving 7/8 HLA-mismatched unrelated donor (MMUD) or 8/8 HLA-matched unrelated donor (MUD) URD-HCT between 2011 and 2018. Primary outcomes included day-180, 1-year, and 2-year overall survival (OS) and relapse-free survival (RFS) for abatacept + CNI/MTX vs CNI/MTX, CNI/MTX + antithymocyte globulin (ATG), and posttransplant cyclophosphamide-based prophylaxis (PT-Cy). For 7/8 MMUDs, day-180 OS (primary end point
