Idiopathic Pulmonary Fibrosis (IPF) is a progressive, fatal lung disorder of unknown cause with a highly variable and unpredictable clinical course. The advances made in deciphering IPF pathobiology over the last decades have led to the approval of two anti-fibrotic molecules, pirfenidone and nintedanib, that showed to be effective in significantly reducing the rate of progression of the disease. Such pharmacological breakthroughs represent a dramatic change in the management of these patients and are reflected in updated international guidelines. However, the need to find a cure for this devastating disease remains unmet and the development of novel therapeutic agents remains hurdled by several factors. Here, we review the latest insights into therapeutic approaches for IPF and the available evidence for the most promising novel compounds currently under development, and discuss the challenges and evolution of IPF clinical research over the next few years.
