The Future of Pharmacological Treatment in Idiopathic Pulmonary Fibrosis

The therapeutic approach in idiopathic pulmonary fibrosis has changed substantially over the past 5 years. National and international guidelines for the pharmacological treatment of IPF recommend 2 antifibrotic drugs, nintedanib and pirfenidone. The use of both these drugs is supported by high-level evidence, with benefits including not only slower disease progression but also a reduction in the annual risk of death. Currently, the therapeutic management of these patients prioritizes both the use of drugs that act on the pathogenic mechanisms of the disease, and the positive effect of improving quality of life with integrated multidisciplinary support, including nutrition, physical activity, education, emotional support, and palliation of symptoms. The overall aim is to ensure that the patient remains as well as possible for as long as possible after diagnosis. However, the goal of the new antifibrotic combinations that are currently under evaluation in clinical trials is to use the potential antifibrotic synergy to enhance the therapeutic benefit or completely halt disease progression, by acting simultaneously on different pathogenic pathways. Another line of investigation involves markers that might be useful for identifying patients who may benefit more from certain antifibrotics than from others, which would make it possible to optimize resources and take the first steps toward precision medicine in pulmonary fibrosis. Below, we review the main potential areas for improvement in the pharmacological treatment of idiopathic pulmonary fibrosis in the short, medium, and long term. (C) 2019 SEPAR.
