About this study
Official title: A Randomized, Double-Blind, Head-to-Head Phase 3 Trial to Evaluate the Efficacy and Safety of LYT-100 (Deupirfenidone) Compared to Pirfenidone at 52 Weeks in Adults With Idiopathic Pulmonary Fibrosis (SURPASS-IPF)
This is a study for adults with a lung disease called idiopathic pulmonary fibrosis. The main purpose of this study is to look at how well deupirfenidone improves lung function and how safe it is for people with idiopathic pulmonary fibrosis (IPF) when compared with pirfenidone. Participants may have been treated with an approved antifibrotic drug for up to a year in the past, but they cannot be on background antifibrotic treatment during this study. Participants will be randomly assigned (meaning by chance) to take either deupirfenidone or pirfenidone 3 times a day, and neither a participant nor their study team will know which study drug participants are on. Participants will be in the study for up to approximately 3 years. During the first year, participants visit the study site up to ten times and afterwards they visit the site every three months. All participants will remain on blinded study drug until the last participant has completed Week 52 Visit. They will have lung function tests, a check of their health, and will tell the study team about any unfavorable effects.
Read the detailed description
This is a Phase 3 randomized, double-blind, head-to-head study comparing deupirfenidone 825 mg TID to pirfenidone 801 mg TID over 52 weeks of treatment in participants with IPF who are not on background therapy. This study is designed to demonstrate superior efficacy of deupirfenidone over pirfenidone as well as support the overall safety profile of deupirfenidone. Prospective participants will initially enter the Screening Period to determine study eligibility (Section 5). Eligible participants will be randomized 1:1 to receive either blinded deupirfenidone 825 mg TID or pirfenidone 801 mg TID as part of the Double-Blind Treatment Period for at least 52 weeks (Period 1). Depending on when participants enter the study, they may continue being treated for up to two more years (Period 2).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Deupirfenidone and Pirfenidone (PFD) in people with Idiopathic Pulmonary Fibrosis (IPF), run by PureTech at 18 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 23 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 18 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Absolute change in forced vital capacity (FVC) measured in mL (time frame: Baseline to Week 52). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07284602, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Oct 2026.
