PureTech Health Receives FDA and EU Orphan Drug Designation
PureTech Health announced that the U.S. Food and Drug Administration and European Commission have granted Orphan Drug Designation to deupirfenidone for the treatment of idiopathic pulmonary fibrosis, a rare, progressive, and fatal lung disease. Deupirfenidone is being advanced by Celea Therapeutics, a Founded Entity established by PureTech to lead its late-stage development and potential commercialization. Results from the global Phase 2b randomized, double-blind, active- and placebo-controlled, dose-ranging ELEVATE IPF trial underscored the differentiated profile of deupirfenidone. In that trial, participants treated with deupirfenidone 825 mg three times a day experienced a slower rate of lung function decline, as measured by change from baseline of Forced Vital Capacity, at 26 weeks versus those who were treated with the FDA-approved dose of pirfenidone 801 mg TID or placebo, with a 91 mL difference between deupirfenidone 825 mg and placebo at 26 weeks. Following the completion of the blinded portion of the trial, 90% of trial completers enrolled in the open-label extension. Those who continued treatment with deupirfenidone 825 mg TID maintained a robust treatment effect and experienced an overall FVC decline of -32.8 mL over a 52-week period,1 which is similar to the expected natural decline in lung function in healthy older adults over that time.

About the author

- 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.
- 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.
- Clinical Data Release: Seaport Therapeutics published first-in-human clinical and preclinical data for GlyphAllo™ in Science Translational Medicine, marking a significant advancement in depression treatment and potentially offering new therapeutic options for patients.
- Drug Efficacy Validation: GlyphAllo demonstrated dose-dependent drug levels in healthy volunteers, with a single 375 mg dose significantly reducing salivary cortisol levels (p=0.0001), indicating its potential in alleviating acute physiological stress responses.
- Clinical Trial Progress: The development of GlyphAllo has advanced to a global randomized double-blind Phase 2b clinical trial, aimed at evaluating its efficacy, safety, and tolerability in patients with major depressive disorder, further enhancing its market prospects.
- Platform Technology Advantage: The successful application of the Glyph platform not only improved GlyphAllo's bioavailability but also showcased its broad applicability beyond neuropsychiatry, potentially leading to new therapeutic solutions in oncology, immunology, and metabolic diseases.
- Executive Participation: PureTech Health's CEO Robert Lyne and Co-founder Eric Elenko will participate in the Leerink Partners Global Healthcare Conference on March 11, 2026, showcasing the company's innovations in biotherapeutics.
- Webcast Availability: The presentation will be available via webcast on PureTech Health's investor website, ensuring that investors and the public can access the latest updates in real-time.
- Company Strategy Overview: PureTech Health is dedicated to developing therapeutics through a capital-efficient R&D model, having successfully launched three products approved by the U.S. FDA, demonstrating its potential in the biotherapeutics sector.
- Cautionary Forward-Looking Statements: The press release includes forward-looking statements, highlighting the risks and uncertainties that may affect the company's future plans and strategies, advising investors to consider relevant risk factors.
- Orphan Drug Designation: PureTech Health announced that its deupirfenidone (LYT-100) has received Orphan Drug Designation from both the FDA and European Commission for treating idiopathic pulmonary fibrosis (IPF), highlighting the drug's potential to address significant unmet medical needs in this rare disease.
- Clinical Trial Results: In the global Phase 2b ELEVATE IPF trial, participants receiving deupirfenidone 825 mg three times daily experienced a significantly slower decline in lung function, with a 26-week FVC change of -21.5 mL compared to -112.5 mL for placebo, demonstrating the drug's superior efficacy.
- Future Research Plans: Celea Therapeutics intends to initiate the Phase 3 SURPASS-IPF trial in the first half of 2026, comparing deupirfenidone to the existing treatment pirfenidone, with successful results potentially providing critical data for drug registration.
- Broad Market Potential: As a next-generation antifibrotic, deupirfenidone may set a new standard of care for IPF and has potential applications in other fibrotic diseases, further solidifying PureTech's leadership in the biotherapeutics sector.

- Orphan Drug Designation: PureTech Health announced that its LYT-100 has received Orphan Drug Designation from both the FDA and the European Commission, aimed at facilitating the development of therapies for rare diseases, highlighting the urgent need for effective treatments in this patient population.
- Clinical Trial Results: In the ELEVATE IPF trial, patients receiving LYT-100 825 mg three times daily experienced a significantly slower decline in lung function, with a change in Forced Vital Capacity (FVC) of -21.5 mL at 26 weeks compared to placebo, indicating its potential in treating idiopathic pulmonary fibrosis.
- Market Demand and Strategic Importance: With only about 25% of idiopathic pulmonary fibrosis patients having received treatment, the development of LYT-100 aims to address this unmet need, potentially providing more effective treatment options and enhancing the company's competitive position in the biopharmaceutical sector.
- Future Development Plans: Celea Therapeutics plans to initiate the Phase 3 SURPASS-IPF trial in the first half of 2026 to compare LYT-100 with the existing therapy pirfenidone, which, if successful, could establish a pathway for potential market approval and further drive company growth.
