FDA-approved therapies for chronic GVHD

Despite novel prophylactic regimens, chronic graft-versus-host disease (cGVHD) remains a challenging complication after allogeneic hematopoietic cell transplantation. cGVHD can affect multiple organs and reduces quality of life, and treatment can cause serious adverse effects. In the past 10 years, the drugs ibrutinib, ruxolitinib, belumosudil, and axatilimab were approved by the US Food and Drug Administration (FDA) for cGVHD. Here, we discuss which signaling pathways and cell types are targeted, the clinical studies that were the basis for FDA approval, and future directions for clinical research.
