The antifibrotic medications pirfenidone and nintedanib became the first US Food and Drug Administration (FDA)-approved medical therapy for the treatment of idiopathic pulmonary fibrosis (IPF) in 2014. This occurred after a pair of randomised controlled trials showed that the drugs slowed the decline in forced vital capacity compared to placebo [1, 2]. Since the medications’ approval, there has been a growing body of literature from pooled meta-analyses and observational studies that suggest the medications may also reduce mortality and all-cause hospitalisations in patients with IPF, outcomes that are difficult to study via clinical trials in a rare, deadly disease such as IPF [3–6].

Consistent with prior observational studies, pirfenidone and nintedanib were observed to have reduced risk of mortality and hospitalisations in patients with IPF in this large US Medicare dataset. The result holds after accounting for “immortal time bias”.
