PureTech stock falls after FDA meeting on IPF drug

PureTech Health PLC (NASDAQ:PRTC) stock dropped in premarket trading after the company received FDA feedback supporting advancement for its idiopathic pulmonary fibrosis (IPF) drug, deupirfenidone, into a pivotal Phase 3 trial. Despite the positive regulatory path, investor concern arose over the timeline, as the Phase 3 trial is not expected to start until the first half of 2026. The new trial aims for potential registration via a 505(b)(2) pathway, building on promising Phase 2b results.
