PureTech+Health+plc (Nasdaq: PRTC, LSE: PRTC) ("PureTech" or the "Company"), a clinical-stage biotherapeutics company dedicated to discovering, developing and commercializing highly differentiated medicines for devastating diseases, today announced the presentation of additional data for PureTech’s LYT-100 (deupirfenidone) at the American Thoracic Society 2022 International Conference. The data were shared in a scientific poster session and detailed the outcomes of a study in healthy older adults showing that LYT-100 demonstrated a lower incidence of adverse events (AEs) compared to pirfenidone at comparable exposure levels. Key outcomes of this study that are supportive of the observed improved tolerability of LYT-100 were+reported in January 2022. The data support the upcoming registration-enabling studies in which PureTech plans to investigate LYT-100 in patients with idiopathic pulmonary fibrosis (IPF) at the planned 550 mg three times daily dose (TID) as well as a dose with a higher total drug exposure than the currently approved dose of pirfenidone to evaluate if higher exposure could translate into improved efficacy.
