Allogeneic hematopoietic stem cell transplantation is hampered by chronic
graft-versus-host disease (cGVHD), resulting in multiorgan fibrosis and
diminished function. Fibrosis in lung and skin leads to progressive bronchiolitis
obliterans (BO) and scleroderma, respectively, for which new treatments are
needed. We evaluated pirfenidone, a Food and Drug Administration (FDA)-approved
drug for idiopathic pulmonary fibrosis, for its therapeutic effect in cGVHD mouse
models with distinct pathophysiology. In a full major histocompatibility complex
(MHC)-mismatched, multiorgan system model with BO, donor T-cell responses that
support pathogenic antibody production are required for cGVHD development.
Pirfenidone treatment beginning one month post-transplant restored pulmonary
function and reversed lung fibrosis, which was associated with reduced macrophage
infiltration and transforming growth factor-? production. Pirfenidone dampened
splenic germinal center B-cell and T-follicular helper cell frequencies that
collaborate to produce antibody. In both a minor histocompatibility
antigen-mismatched as well as a MHC-haploidentical model of sclerodermatous
cGVHD, pirfenidone significantly reduced macrophages in the skin, although
clinical improvement of scleroderma was only seen in one model. In vitro
chemotaxis assays demonstrated that pirfenidone impaired macrophage migration to
monocyte chemoattractant protein-1 (MCP-1) as well as IL-17A, which has been
linked to cGVHD generation. Taken together, our data suggest that pirfenidone is
a potential therapeutic agent to ameliorate fibrosis in cGVHD.
