PureTech to Present at CHEST 2024 Annual Meeting

Three presentations inform clinical, commercial and patient engagement strategies for LYT-100 for the treatment of idiopathic pulmonary fibrosis (IPF)

Topline data from the Phase 2b ELEVATE IPF trial of LYT-100 expected by the end of 2024

PureTech Health plc (Nasdaq: PRTC, LSE: PRTC) ("PureTech" or the "Company"), a clinical-stage biotherapeutics company dedicated to changing the lives of patients with devastating diseases, today announced its onsite presence at the CHEST 2024 Annual Meeting in Boston, Massachusetts, from October 6-9. The Company will deliver two oral presentations and one poster relating to LYT-100 (deupirfenidone) for the treatment of idiopathic pulmonary fibrosis (IPF) as well as the Company's research surrounding the experiences of patients with IPF.

The data to be presented have informed the clinical and commercial strategies supporting LYT-100 as well as advocacy and patient engagement work around the management and treatment of people with IPF. Topline results from the Phase 2b ELEVATE IPF trial are expected by the end of 2024. A streamlined development program for LYT-100 is planned using the same endpoints that have supported past IPF product approvals. Pending positive clinical outcomes from the Phase 2b trial and regulatory feedback, the program is expected to advance into a Phase 3 trial. PureTech believes the results of the Phase 2b trial, together with a successful Phase 3 trial, could serve as the basis for registration in the U.S. and other geographies.

About Idiopathic Pulmonary Fibrosis (IPF)

IPF is a rare, progressive and fatal lung disease with a median survival of 2-5 years.[1] Pirfenidone is one of only two drugs approved to treat IPF, and for those patients able to tolerate treatment, it has been shown to improve survival by approximately 2.5 years compared to supportive care alone.¹ However, tolerability issues with both of the standard-of-care drugs result in patients discontinuing treatment or reducing their dose. This contributes to nearly three out of every four people with IPF choosing to forego treatment with these otherwise efficacious medicines.[2]

About LYT-100 (Deupirfenidone)

LYT-100 (deupirfenidone) is being advanced for the treatment of conditions involving inflammation and fibrosis, including IPF. It is a deuterated form of pirfenidone that is designed to retain the beneficial pharmacology and clinically-validated efficacy of pirfenidone with a highly differentiated PK profile. LYT-100 has also demonstrated favorable tolerability across multiple clinical studies in more than 400 individuals.

Pirfenidone is one of the two standard-of-care treatments approved for IPF, along with nintedanib, both of which are efficacious but associated with significant tolerability issues. These tolerability issues result in treatment discontinuations and/or dose reductions below the FDA-approved dose, thereby limiting the effectiveness of these otherwise efficacious medicines. With LYT-100, PureTech aims to deliver better outcomes for patients by enabling individuals to maintain the same or higher pirfenidone-equivalent doses for longer. PureTech believes LYT-100 has the potential both to supplant the current standard-of-care treatments and to serve a larger market of patients who are unable to tolerate current therapies. Topline data for the global Phase 2 ELEVATE IPF trial are expected by the end of 2024.
