Fibrotic Lung Diseases

Progressive fibrosing interstitial lung disease (PF-ILD) describes a phenotypic subset of interstitial lung diseases characterized by progressive, intractable lung fibrosis. PF-ILD is separate from, but has radiographic, histopathologic, and clinical similarities to idiopathic pulmonary fibrosis. Two antifibrotic medications, nintedanib and pirfenidone, have been approved for use in patients with idiopathic pulmonary fibrosis. Recently completed randomized controlled trials have demonstrated the clinical efficacy of antifibrotic therapy in patients with PF-ILD. The validation of efficacy of antifibrotic therapy in PF-ILD has changed the treatment landscape for all of the fibrotic lung diseases, providing a new treatment pathway and opening the door for combined antifibrotic and immunosuppressant drug therapy to address both the fibrotic and inflammatory components of ILD characterized by mixed pathophysiologic pathways.

Abstract Background Currently, there are two antifibrotics used to treat idiopathic pulmonary fibrosis (IPF): pirfenidone and nintedanib. Antifibrotics slow disease progression by reducing the annual decline of forced vital capacity (FVC), which possibly improves outcomes in IPF patients. During treatment, patients occasionally switch antifibrotic treatments. However, prognostic implication of changing antifibrotics has not yet been evaluated. Methods This multi-center retrospective cohort study examined 262 consecutive IPF patients who received antifibrotic therapy. Antifibrotic agents were switched in 37 patients (14.1%). The prognoses were compared between the patient cohort that switched antifibrotics (Switch-IPF) and those without (Non-Switch-IPF) using propensity-score matched analyses. Results The median period between the initiation of antifibrotic therapy and the drug switch was 25.8 (12.7–35.3) months. The most common reasons for the switch were disease progression (n = 17) followed by gastrointestinal disorders (n = 12). Of the 37 patients that switched antifibrotics, only eight patients disrupted switched antifibrotics by their adverse reactions. The overall prognosis of the Switch-IPF cohort was significantly better than the Non-Switch-IPF cohort (median periods: 67.2 vs. 27.1 months, p < 0.0001). In propensity-score matched analyses that were adjusted to age, sex, FVC (%), history of acute exacerbation, and usage of long-term oxygen therapy, the Switch-IPF cohort had significantly longer survival times than the Non-Switch-IPF group (median 67.2 vs. 41.3 months, p = 0.0219). The second-line antifibrotic therapy showed similar survival probabilities than those in first-line antifibrotic therapy in multistate model analyses. Conclusion Switching antifibrotics is feasible and may improve prognosis in patients with IPF. A further prospective study will be required to confirm clinical implication of switching the antifibrotics.

Pirfenidone and nintedanib are oral antifibrotic agents approved for the treatment of idiopathic pulmonary fibrosis (IPF). Real-world data on factors that influence IPF treatment decisions are limited. Physician characteristics associated with antifibrotic therapy initiation following an IPF diagnosis were examined in a sample of US pulmonologists. An online, self-administered survey was fielded to pulmonologists between April 10, 2017, and May 17, 2017. Pulmonologists were included if they spent >20% of their time in direct patient care and had ≥5 patients with IPF receiving antifibrotics. Participants answered questions regarding timing and reasons for considering the initiation of antifibrotic therapy after an IPF diagnosis. A total of 169 pulmonologists participated. The majority (81.7%) considered initiating antifibrotic therapy immediately after IPF diagnosis all or most of the time (immediate group), while 18.3% considered it only some of the time or not at all (delayed group). Pulmonologists in the immediate group were more likely to work in private practice (26.1%), have a greater mean percentage of patients receiving antifibrotic therapy (60.8%), and decide to initiate treatment themselves (31.2%) versus those in the delayed group (16.1%, 30.5%, and 16.1%, respectively). Most pulmonologists consider initiating antifibrotic treatment immediately after establishing an IPF diagnosis all or most of the time versus using a “watch-and-wait” approach. Distinguishing characteristics between pulmonologists in the immediate group versus the delayed group included practice setting, percentage of patients receiving antifibrotic therapy, and the decision-making dynamics between the patient and the pulmonologist.
