PureTech (Nasdaq: PRTC) announced that Celea Therapeutics completed an End-of-Phase 2 meeting with the FDA for deupirfenidone (LYT-100) in idiopathic pulmonary fibrosis (IPF).
The FDA feedback supports advancing to a global pivotal Phase 3 SURPASS-IPF trial, planned to start in the first half of 2026, and indicates a streamlined 505(b)(2) pathway could be possible if a single Phase 3 is successful and supported by the totality of deupirfenidone data. Phase 3 will be a 52-week, randomized, double-blind head-to-head trial versus pirfenidone, with primary endpoint change in absolute FVC at week 52.
Phase 2b ELEVATE-IPF results cited: deupirfenidone 825 mg TID showed a 91 mL FVC advantage vs placebo at 26 weeks and a maintained -32.8 mL FVC decline over 52 weeks in extension. Celea expects to finalize financing in early 2026 to support Phase 3 initiation.
Gallop Oncology (Nasdaq:PRTC) announced initial topline Phase 1b results for LYT-200 in relapsed/refractory AML and high-risk MDS, showing a favorable safety profile and encouraging efficacy.
At the proposed Phase 2 dose (12 mg/kg) in combination with venetoclax/hypomethylating agent: 38% combined complete response, 97% disease control, and initial median overall survival of 13.2 months. Monotherapy median overall survival was 6.5 months. No LYT-200–related serious adverse events or dose‑limiting toxicities observed (n=101). Final overall survival data expected in 1H 2026; additional details to be presented at ASH 2025 on December 6, 2025.

The study demonstrated that patients switching from placebo or pirfenidone to deupirfenidone achieved lung function stabilization with favorable tolerability.
Key findings include patients switching from placebo to deupirfenidone showing a mean FVC change of +20.0 mL, while those switching from pirfenidone showed -23.1 mL. The drug maintained its efficacy over 52 weeks, with an overall FVC decline of -32.8 mL, comparable to natural decline in healthy older adults.

PureTech's (NASDAQ: PRTC) Founded Entity, Seaport Therapeutics, has initiated a Phase 1 clinical trial of GlyphAgo™ (SPT-320), marking its second therapeutic candidate to enter clinical development. GlyphAgo is an oral prodrug of agomelatine designed to treat Generalized Anxiety Disorder (GAD).
The novel drug aims to overcome agomelatine's key limitation of first-pass liver metabolism by utilizing Seaport's proprietary Glyph™ platform to shift absorption toward intestinal lymphatics. Preclinical studies showed over 50% lymphatic transport and 10-fold increased plasma exposure compared to agomelatine alone.
The Phase 1 study will evaluate safety, tolerability, and pharmacokinetics in healthy volunteers, with the goal of achieving therapeutic levels at lower doses while reducing liver exposure.

Key findings include sustained efficacy through 52 weeks in the open-label extension study, with patients experiencing only a -32.8 mL decline in FVC, similar to natural decline in healthy older adults. The company also revealed that 69% of IPF patients in preference studies favored treatments offering greater efficacy over improved tolerability.
PureTech's newly launched Founded Entity, Celea Therapeutics, will advance deupirfenidone into Phase 3 trials, positioning it as a potential new standard of care in IPF treatment.
