Pulmongene (Beijing) Ltd.<\/strong> announced that PMG1015<\/strong> received Fast Track Designation (FTD)<\/strong> from the U.S. Food and Drug Administration (FDA)<\/strong> for the treatment of idiopathic pulmonary fibrosis (IPF)<\/strong>. The first-in-class monoclonal antibody targeting amphiregulin (AREG)<\/strong>, a key upstream driver of fibrosis<\/strong>, demonstrated favorable safety and encouraging preliminary efficacy<\/strong> in its completed Phase Ib\/IIa trial<\/strong>, including FVC stabilization and AI-based HRCT biomarker improvements<\/strong>.<\/p>\n\n\n\n
