- Positive FDA Feedback: PureTech successfully completed an End-of-Phase 2 meeting with the FDA, laying the groundwork for the Phase 3 SURPASS-IPF trial of LYT-100, expected to initiate in the first half of 2026, showcasing the company's strong potential in treating idiopathic pulmonary fibrosis (IPF).
- Optimized Trial Design: The Phase 3 trial will compare LYT-100 at 825 mg TID against pirfenidone at 801 mg TID, with the primary endpoint assessing changes in forced vital capacity (FVC) at 52 weeks, aiming to validate LYT-100's superiority and establish it as a new standard of care.
- Clinical Data Support: In the Phase 2b ELEVATE IPF trial, LYT-100 demonstrated significant lung function improvement, with a decline rate of -21.5 mL at 26 weeks compared to -112.5 mL in the control group, indicating its effectiveness in slowing disease progression.
- Clear Financing Plans: Celea Therapeutics expects to finalize financing in early 2026 to support the initiation of the Phase 3 trial, paving the way for LYT-100's commercialization and further enhancing PureTech's competitiveness in the biotherapeutics sector.
