Cost-effectiveness of pirfenidone compared to all available strategies for the treatment of idiopathic pulmonary fibrosis in France.

: To update the health economic evaluation of pirfenidone in the treatment of idiopathic pulmonary fibrosis (IPF) compared to all available alternatives strategies (Best supportive care - BSC and nintedanib), based on a cost-utility model previously validated by the CEESP's (French Committee for Economic Evaluation) in 2014. : A standard Markov cohort model, adapted to French methodology guidelines, was used to simulate the therapeutic management and the course of IPF patients (including potential adverse events) using the collective perspective. Cost-effectiveness was evaluated regarding life years (LY); quality-adjusted life-years (QALY); average cumulative costs; the incremental cost-effectiveness ratio (ICER) expressed in cost per QALY gained.
