Background: The INPULSIS trials revealed that nintedanib reduced the decline in lung function in patients with idiopathic pulmonary fibrosis. We aimed to evaluate the efficacy and safety of nintedanib in Japanese idiopathic pulmonary fibrosis patients in real-world settings. Method: Medical records of idiopathic pulmonary fibrosis patients, who received treatment with nintedanib in five institutions between July 2015 and June 2017, were reviewed. Patients with % forced vital capacity ⩾50% and % predicted diffusing capacity of the lung carbon monoxide ⩾30% were classified as the moderate group and those with more impaired lung functions as the severe group. Result: Among 158 patients analyzed, 132 (84.6%) were classified as the moderate group and 26 (15.4%) as the severe group. In the moderate group, changes in forced vital capacity in 12 months were significantly different between before and after nintedanib administration (−253 ± 163 vs −125 ± 235 mL; p = 0.0027). In contrast, changes in forced vital capacity in 12 months were not significantly changed by nintedanib treatment in the severe group (−353 ± 250 vs −112 ± 341 mL; p = 0.2374). Incidence of acute exacerbation was higher in the severe group than in the moderate group (30.8% vs 18.9%). The overall survival of the moderate and the severe groups was 17.2 and 10.1 months. Conclusion: In real-world practice, nintedanib showed comparable efficacy to those observed in previous trials. In the severe group, the efficacy of nintedanib might be limited.
