Advances in graft-versus-host disease prevention strategies: latest updates from the 2022 ASH annual meeting

This review summarizes the significant advancements in prophylaxis against graft-versus-host disease (GvHD) presented at the 2022 ASH Annual Meeting. The use of innovative agents and regimens, along with the conventional prophylactic approach of combining post-transplant cyclophosphamide and anti-thymocyte globulin, were discussed. The innovative agents and regimens highlighted in this review include abatacept, the first FDA-approved drug for acute GvHD prophylaxis; RGI-2001, which promotes the expansion of regulatory T cells; and cell therapies such as Orca-T and Orca-Q. These advancements provide promising strategies and options for GvHD prevention, offering hope for improved post-transplant patient outcomes in terms of survival rates.
