Daewoong Pharmaceutical presented interim Phase 2 results for Bersiporocin (DWN12088), a first-in-class oral antifibrotic drug targeting idiopathic pulmonary fibrosis, at the 2025 American Thoracic Society International Conference.
The ongoing randomized, double-blind, placebo-controlled study is enrolling 102 patients across 30 sites in the U.S. and South Korea, with over 50% of participants being Asian, enabling assessment across ethnic subgroups.
Bersiporocin selectively inhibits Prolyl-tRNA Synthetase (PRS) to interrupt collagen biosynthesis and fibrotic cascade progression, representing a novel mechanism of action in IPF treatment.
The drug has received Orphan Drug Designation from both FDA and EMA, plus Fast Track designation from FDA, with 80% of target enrollment completed as of April 2025.
