Study Evaluating INS018_055 Administered Orally to Subjects With Idiopathic Pulmonary Fibrosis

Idiopathic pulmonary fibrosis is a fatal lung disease characterized by reduced quality of life (QoL) and a median survival of 3 to 4 years. While current standard of care (SoC) treatments including pirfenidone and nintedanib slow disease progression, they are not curative and poorly tolerated due to their toxicity profiles. To address the need for new treatments in IPF, InSilico Medicine is developing INS018_055, a potent inhibitor of the serine/threonine kinase Traf2- and Nckinteracting kinase (TNIK).
