PureTech Health plc (Nasdaq: PRTC, LSE: PRTC) ("PureTech" or the "Company"), a hub-and-spoke biotherapeutics company dedicated to giving life to science and transforming innovation into value, today announced the presentation of new analyses from the Phase 2b ELEVATE IPF trial of deupirfenidone (LYT-100) for the treatment of idiopathic pulmonary fibrosis (IPF). The data show that the favorable safety and efficacy profile of deupirfenidone was consistent across age groups, including in patients aged 75 years and older. These findings, presented at the American College of Chest Physicians (CHEST) 2025 Annual Meeting, suggest that deupirfenidone may address a key gap in the treatment of IPF, as older patients have historically been less likely to be treated, largely due to tolerability challenges.1,2 These data further reinforce deupirfenidone’s differentiated profile and support its potential to meaningfully improve care for this vulnerable population.
