Background: Real-life data on the use of pirfenidone and nintedanib to treat patients with idiopathic pulmonary fibrosis (IPF) are still scarce., Methods: We compared the efficacy of either pirfenidone (n = 78) or nintedanib (n = 28) delivered over a 24-month period in patients with IPF, followed at two regional clinic centers in Italy, with a group of patients who refused the treatment (n = 36), and who were considered to be controls. All patients completed regular visits at 1- to 3-month intervals, where primary [forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO)] and secondary outcomes (side effects, treatment compliance, and mortality) were recorded., Results: Over time, the decline in FVC and DLCO was significantly higher (p = 0.0053 and p = 0.037, respectively) in controls when compared with the combined treated group, with no significant difference between the two treated groups. Compared to patients with less advanced disease (GAP (Gender, Age, Physiology) stage I), those in GAP stages II and III showed a significantly higher decline in both FVC and DLCO irrespective of the drug taken. Side effects were similarly reported in patients receiving pirfenidone and nintedanib (5% and 7%, respectively), whereas mortality did not differ among the three groups., Conclusion: This real-life study demonstrated that both pirfenidone and nintedanib were equally effective in reducing the decline of FVC and DLCO versus non-treated patients after 24 months of treatment; however, patients with more advanced disease were likely to show a more rapid decline in respiratory function., (Copyright © 2019 Elsevier Ltd.

Rationale: Real-world data on pirfenidone treatment of patients with idiopathic pulmonary fibrosis (IPF) are limited. This study assessed the effectiveness of pirfenidone in a large real-life Italian IPF cohort., Methods: IRENE was an observational, retrospective study of patients with IPF treated with pirfenidone in routine clinical practice (18 centres). At Month 6, a mandatory re-evaluation of forced vital capacity (FVC) decline (absolute change < 10%) was required to continue pirfenidone. The primary effectiveness outcomes were absolute change from baseline in FVC and the percentage of patients with ≥ 10% absolute decline in % predicted FVC at Month 12. Safety was described by adverse event (AE) occurrence. Prespecified subgroups included sex, age, presence/absence of emphysema, usual interstitial pneumonia (UIP) pattern on high-resolution computed tomography, and baseline lung function., Results: The study included 379 patients (mean age, 67.6 years; 78.1% male). Mean change from baseline in FVC and the percentage of patients with ≥ 10% absolute decline in % predicted FVC at Month 12 were -81.8 mL (SD, 419.6 mL; P = 0.002) and 16.0% (95% CI, 12.2-20.9%), respectively. Disease progression was similar across prespecified subgroups, including patients with definite vs possible UIP. Overall, 211 AEs occurred in 149 patients (39.3%), with serious AEs in 31 patients (8.2%) and 9 discontinuations due to AEs. Skin and gastrointestinal AEs were most frequent. Fifteen patients (4.0%) died., Conclusions: The decline in FVC and the safety profile observed in this real-world IPF cohort were consistent with the findings of the Phase III pirfenidone trials., (Copyright © 2019 Elsevier Ltd.
