The Burden Of Progressive Fibrotic Interstitial Lung Disease Across The Uk

While Idiopathic pulmonary fibrosis (IPF) remains the exemplar progressive fibrotic lung disease, there remains a cohort of non-IPF fibrotic lung diseases (fILD) which adopt a similar clinical behaviour to IPF despite therapy [1]. This phenotypically related group of conditions, where progression of disease is similar to that seen in IPF, have recently been described as Progressive Fibrotic Interstitial Lung diseases (PF-ILD) [2]. Historically treatments for these cases have been limited though given the phenotypic similarities many cases may have been given a multidisciplinary working diagnosis of IPF based on their disease behaviour [3]. The INBUILD trial broadened the scope of treatable fILD by demonstrating a significant benefit of Nintedanib in patients with fILD and progressive disease [4]. In response to this the European Commission (EC) approved an additional indication for Nintedanib in adults for the treatment of PF-ILD in July 2020.\n\nFootnotes \n\nThis manuscript has recently been accepted for publication in the European Respiratory Journal .
