Bridge Biotherapeutics, Daewoong, and Ildong Pharmaceutical lead in IPF treatment development, with Bridge's BBT-877 in Phase 2 trials targeting autotaxin. Daewoong's Versiporocin aims to reduce PRS protein action, while Ildong's IL1512 targets CXCR7. Hanmi's HM15211, initially for MASH, shows IPF efficacy. Boehringer Ingelheim's Nerandomilast met primary trial endpoints, but side effects are a concern.
