Announcement
PureTech Health plc noted that its Founded Entity, Seaport Therapeutics announced the publication of new data showcasing the GlyphTM platform's unique ability to enhance drug transport through the lymphatic system for increased therapeutic exposure.
AI Summary
PureTech Health plc recently announced that its Founded Entity, Seaport Therapeutics, published new data demonstrating the unique benefits of the Glyph™ platform. The study, featured in Molecular Pharmaceutics, showed that a novel prodrug attachment point on an immunomodulatory drug resulted in the highest reported lymphatic transport to date—about 55 percent drug absorption via the lymphatic system.
The research revealed that the new linkers released up to twice as much drug in the lymph nodes compared to previous attachment methods, enhancing direct access to the immune system. These findings support the idea that tailoring drug attachment sites can improve lymphatic drug delivery and overall therapeutic exposure, reinforcing the versatility and potential of the Glyph™ platform in the development of more effective treatments.

Announcement
PureTech Health plc announced positive results from ELEVATE IPF, a Phase 2b randomized, double-blind, active- and placebo-controlled, dose-ranging trial evaluating deupirfenidone (LYT-100) at two dose levels three times a day (TID) over 26 weeks in patients with idiopathic pulmonary fibrosis (IPF).
AI Summary
PureTech Health recently announced positive results from its Phase 2b ELEVATE IPF trial studying deupirfenidone (LYT-100) in patients with idiopathic pulmonary fibrosis (IPF). In this study, patients received either 550 mg or 825 mg three times a day for 26 weeks. The trial was carefully designed using both active and placebo controls, and it compared deupirfenidone to the standard treatment pirfenidone.
The results showed a clear dose-dependent effect. The higher dose of 825 mg significantly slowed lung function decline to nearly normal levels, with a treatment effect of 80.9% versus placebo—much greater than the 54.1% effect seen with pirfenidone. Moreover, deupirfenidone was well tolerated, demonstrating a favorable safety profile. These promising findings support the further development of deupirfenidone as a potential new treatment option for IPF.
