The effect of nintedanib on health-related quality of life in Japanese patients with progressive fibrosing interstitial lung diseases: A subset analysis of the INBUILD trial

In previous Japanese subgroup/subset analyses of the global INBUILD trial, nintedanib reduced the annual rate of forced vital capacity (FVC) decline and the risk of disease progression in patients with progressive fibrosing interstitial lung diseases (PF-ILDs). This exploratory subset analysis assessed the effect of nintedanib on symptoms and impacts of pulmonary fibrosis in Japanese patients with PF-ILDs, including those with usual interstitial pneumonia (UIP)-like fibrotic pattern on high-resolution computed tomography (HRCT).
