Ziritaxestat is a small-molecule, selective autotaxin inhibitor that was investigated as a potential treatment for idiopathic pulmonary fibrosis (IPF).^[1] Initially showing promise in early-phase studies, ziritaxestat underwent evaluation in two large-scale phase 3 clinical trials, ISABELA 1 and ISABELA 2.^[1]^[2] These trials aimed to assess the efficacy and safety of ziritaxestat in patients with IPF, including those receiving standard of care treatment with pirfenidone or nintedanib.^[1] However, both trials were prematurely terminated due to a lack of efficacy, as ziritaxestat failed to demonstrate significant improvement in lung function or other clinical outcomes compared to placebo.^[1]^[2]^[3]
