We hope this research will help improve communications between people with IPF and their healthcare teams. It also informs our work to develop a new IPF treatment option, which we believe will address key limitations of the current standard-of-care medicines.\"\nPureTech presented qualitative and quantitative research that highlights both the burden of IPF as well as gaps in disease management that exacerbate the quality of life for people with IPF. The 90-person survey found that the majority of participants experience a high burden of disease that interferes with their normal activities, including shortness of breath (86%), fatigue (78%) and cough (77%). In addition to the burden of the disease itself, comorbidities, side effects of antifibrotic treatment and the use of supplemental oxygen interfere with patients’ quality of life, suggesting a need for improved interventions to manage symptoms.\nBeyond this, PureTech’s research revealed commonalities and differences in the patient experience for those receiving care at interstitial lung disease (ILD) centers (n=45) versus community pulmonary practices (CPP) (n=45). When asked about their top resources for IPF information, nearly all people in both care settings listed their pulmonologist as their primary source, and the majority in each were very satisfied with their communications about their IPF diagnosis. Antifibrotic treatment rates at ILD centers and CPPs were similar, but differences existed in perceived communication around antifibrotic treatment options. 76% of people receiving care in ILD centers reported that their pulmonologist had discussed both FDA-approved antifibrotics with them, while this was only true of 56% of those receiving care at CPPs. Across a series of quality-of-life parameters, patients at CPPs indicated a higher impact and severity of their disease than patients at ILD centers, reflecting an important discrepancy that merits further investigation.\nPureTech also presented a clinical abstract reviewing its plan to evaluate the primary outcome of the Phase 2b ELEVATE IPF clinical trial using a prespecified Bayesian approach. ELEVATE IPF is PureTech’s randomized, double-blind, placebo-controlled, dose-finding study designed to evaluate the efficacy, tolerability, safety and dosing regimen of LYT-100 in patients with IPF compared to placebo. The trial will also assess the relative efficacy of two doses of LYT-100. Participants have been randomized in a ratio of 1:1:1:1 to receive either 550 mg of LYT-100, 825 mg of LYT-100, pirfenidone or placebo three times a day (TID) for up to 26 weeks and have the option to enroll in an open-label extension. The primary endpoint is the rate of decline in Forced Vital Capacity (FVC) for the combined LYT-100 arms versus placebo over the 26-week treatment period using a Bayesian linear mixed effects model including dynamic borrowing. This approach augments the placebo arm sample size with external placebo data from historical IPF trials. A Bayesian approach has the advantage of enhancing overall statistical power and improving decision-making while limiting the number of patients required to be treated with placebo in a fatal disease. This approach has been used previously in Phase 2 trials of novel IPF therapeutics.\n\"Bayesian dynamic borrowing allows us to leverage historical trial data for the placebo arm to maximize the number of patients exposed to active treatment arms and minimize the number exposed to placebo,\" said Carol Ann Satler, MD, PhD, Senior Director, Clinical Development at PureTech. \"IPF is a rare, fatal disease, underscoring the importance of efficient clinical trial design. Bayesian analyses have previously been leveraged in IPF studies for this reason, especially given the substantial historical placebo dataset in IPF, and we look forward to sharing results from our Phase 2b trial by the end of this year.\"\nTopline 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 and regulatory feedback, the program will advance into a Phase 3 clinical 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.\nAbout Idiopathic Pulmonary Fibrosis (IPF)\nIPF 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\nAbout LYT-100 (Deupirfenidone)\nLYT-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.\nPirfenidone 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 comparable 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.\nAbout PureTech Health\nPureTech is a clinical-stage biotherapeutics company dedicated to giving life to new classes of medicine to change the lives of patients with devastating diseases. The Company has created a broad and deep pipeline through its experienced research and development team and its extensive network of scientists, clinicians and industry leaders that is being advanced both internally and through its Founded Entities. PureTech's R&D engine has resulted in the development of 29 therapeutics and therapeutic candidates, including three that have been approved by the U.S. Food and Drug Administration. A number of these programs are being advanced by PureTech or its Founded Entities in various indications and stages of clinical development, including registration enabling studies. All of the underlying programs and platforms that resulted in this pipeline of therapeutic candidates were initially identified or discovered and then advanced by the PureTech team through key validation points.\nFor more information, visit www.puretechhealth.com or connect with us on X (formerly Twitter) @puretechh.\nCautionary Note Regarding Forward-Looking Statements\nThis press release contains statements that are or may be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
