Industry Developments:

In October 2025, Pirfenidone clinical findings published for BOS related to chronic graft?versus?host disease. A phase?1, single?arm study showed that pirfenidone was safe and tolerable in BOS patients after hematopoietic cell transplant and may improve lung function, supporting further research into antifibrotic treatment strategies.

In November 2025, European multicenter randomized Phase II trial of pirfenidone in BOS after bilateral lung transplantation published. This multisite study evaluated pirfenidone for progressive BOS post?transplant, contributing important clinical evidence; although results did not definitively demonstrate superiority over placebo, it informs future therapeutic exploration.
