Deupirfenidone Shows Significant Efficacy in Idiopathic Pulmonary Fibrosis
- Significant Efficacy: In a 26-week clinical trial, deupirfenidone 825 mg TID monotherapy significantly slowed lung function decline in patients with idiopathic pulmonary fibrosis, with an adjusted mean FVC difference of 91 mL (p=0.02), approaching the lung function changes expected in healthy aging, indicating its potential in treatment.
- Standard Treatment Comparison: This trial is the first industry-sponsored IPF trial to include a current standard-of-care treatment as an active comparator, enhancing the interpretability of efficacy and safety findings and laying a solid foundation for the upcoming Phase 3 SURPASS-IPF trial.
- Financing Plans: PureTech's subsidiary, Celea Therapeutics, is working to complete financing to initiate the Phase 3 SURPASS-IPF trial in the first half of 2026, aiming to further validate the efficacy of deupirfenidone and push it towards becoming a new standard of care.
- Drug Exposure and Tolerability: Deupirfenidone 825 mg TID showed approximately 50% greater drug exposure compared to pirfenidone 801 mg TID, yet the incidence of adverse events was similar (85.9% vs 84.1%), demonstrating its ability to enhance efficacy while maintaining good tolerability.

Seaport Therapeutics Announces Positive Clinical Data for GlyphAgo
- Clinical Trial Success: Seaport Therapeutics reported positive topline data from its GlyphAgo clinical trial, demonstrating a 6.8-fold increase in bioavailability compared to unmodified agomelatine, exceeding the expected 2-fold target, indicating GlyphAgo's potential in treating generalized anxiety disorder (GAD).
- Good Safety Profile: GlyphAgo exhibited good tolerability across all evaluated doses in the trial, with no serious adverse events or liver-related side effects reported, enhancing its safety profile and potential market acceptance.
- Follow-up Trial Plans: Based on the trial results, Seaport plans to advance GlyphAgo into two parallel clinical trials, including a Phase 2a trial to assess its potential sleep benefits in GAD patients and a registration-enabling Phase 2b randomized controlled trial, further validating its clinical application.
- Platform Advantages: GlyphAgo leverages Seaport's Glyph platform to avoid first-pass liver metabolism, enhancing systemic exposure to agomelatine while reducing liver exposure risks, positioning it as a leading treatment option for GAD and addressing unmet market needs.
