Announcement
PureTech Health plc announced new data from the open-label extension (OLE) of its Phase 2b ELEVATE IPF trial of deupirfenidone (LYT-100) in people living with idiopathic pulmonary fibrosis (IPF).
AI Summary
PureTech Health plc announced new data from the open-label extension (OLE) of its Phase 2b ELEVATE IPF trial of deupirfenidone (LYT-100) in people living with idiopathic pulmonary fibrosis (IPF). In this extension, 170 participants (over 90% of those completing the blinded phase) who switched to deupirfenidone 825 mg three times daily after 26 weeks on placebo or pirfenidone showed stabilized lung function. The placebo-to-deupirfenidone group had a mean forced vital capacity (FVC) gain of +20 mL, while the pirfenidone-to-deupirfenidone group had a mean decline of –23 mL over the 26-week extension.
These findings reinforce results from the initial 26-week study and suggest a durable treatment effect comparable to the natural FVC decline in healthy older adults. Deupirfenidone was well tolerated, with common side effects including nausea, dyspepsia, upper respiratory infections, and cough, mirroring earlier safety data.
PureTech is actively engaging with regulators and expects to finalize its Phase 3 trial design by Q4 2025, aiming to establish deupirfenidone as a potential new standard of care for IPF.

Announcement
PureTech Health plc announced that the first participant has been dosed in the Phase 1 study of GlyphAgo™ (SPT-320 or Glyph Agomelatine).
AI Summary
PureTech Health plc’s founded entity, Seaport Therapeutics, has dosed the first participant in a Phase 1 study of GlyphAgo™ (SPT-320 or Glyph Agomelatine). This marks the second candidate from Seaport’s pipeline to enter clinical development. The study is being conducted in healthy adult volunteers.
GlyphAgo is an oral prodrug of agomelatine, a drug already shown to work well in generalized anxiety disorder (GAD). Seaport’s Glyph™ platform shifts absorption into the intestinal lymphatic system. This helps the drug avoid first-pass liver metabolism and increases its overall exposure in the body.
The Phase 1 proof-of-concept trial will assess safety, tolerability, and pharmacokinetics. It includes single- and multiple-ascending dose phases, plus a food-effect crossover part. Researchers aim to show that therapeutic drug levels can be reached at lower doses with less liver exposure.
By reducing liver metabolism, GlyphAgo may lower the risk of liver enzyme elevations and cut down on monitoring needs. If successful, this approach could deliver agomelatine’s benefits with an improved safety profile.
The study’s results will help determine whether GlyphAgo can redefine GAD treatment for patients worldwide.
