Deupirfenidone vs Pirfenidone for IPF in Adults
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)
Run by PureTech · NCT07284602 · Data updated 2026-11-12
This study tests whether deupirfenidone can improve lung function better than pirfenidone in adults with idiopathic pulmonary fibrosis who aren’t on other antifibrotic meds.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 40 and older with IPF, not on background antifibrotic therapy, with UIP pattern on HRCT and FVC at least 45% of predicted.
✕Probably not a fit
Patients who do not respond to either drug or who experience unacceptable safety issues during the trial may not benefit.

What this trial studies
This Phase 3, randomized, double-blind, head-to-head trial compares deupirfenidone taken three times daily with pirfenidone taken three times daily in adults with IPF. Participants will be screened for eligibility, then randomly receive one of the blinded treatments for up to 52 weeks, with possible extension for up to two additional years. The primary goal is to see if deupirfenidone improves lung function and maintains an acceptable safety profile compared with pirfenidone. Participants will have frequent visits in year one and quarterly visits thereafter, with ongoing blinded treatment until all participants complete the initial 52-week period.
Why it matters
Potential benefit: If successful, the study could show a new treatment option that may improve lung function and safety for IPF patients.
How similar studies have gone: Prior trials in IPF have explored antifibrotic drugs, but head-to-head comparisons like this are relatively novel.

Inclusion Criteria: * Is ≥40 years of age at the time of informed consent. * Meets the diagnostic criteria of IPF American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Society (ALAT) 2022 guidelines. * Has a maximum time from initial IPF diagnosis of 7 years. * Has no prior exposure to pirfenidone or LYT-100. * Has definite or probable unusual interstitial pneumonia (UIP) on HRCT, performed within 12 months prior to Visit 1 and confirmed by the central reader. * Has an FVC ≥45% of predicted normal at Visit 1. Exclusion Criteria: * Has, in the opinion of the Investigator, significant clinical worsening of IPF between Visit 1 and Visit 2 (eg, clinically significant hospitalization, clinically significant respiratory event). * Has been hospitalized within 3 months prior to Visit 1 for acute exacerbation of IPF or other significant respiratory complication. * Has prebronchodilator forced expiratory volume in 1 second (FEV1)/FVC \<0.7 at Visit 1. * Has a greater extent of emphysema vs fibrosis on the most recent HRCT scan as confirmed by the central reader. * Has a diagnosis of any condition that could be an explanation for interstitial lung disease (ILD). * Has a major extrapulmonary condition that could affect spirometry. * Has a current diagnosis of other relevant respiratory disorders. * Has significant pulmonary hypertension (PH). * Has had a lung transplant. * Has cardiovascular disease. * Has underlying chronic liver disease/impairment. * Has relevant chronic or acute infections including active viral hepatitis or poorly controlled HIV. * Has had any major surgical procedures performed within 6 weeks prior to Visit 1 or is planning to have a major surgical procedure during the study. * Has any documented active or suspected malignancy or history of malignancy within 5 years prior to Visit 1. * Has any of the following laboratory abnormalities at Visit 1: * Aspartate aminotransferase (AST) or Alanine aminotransferase (ALT) \>1.5 × upper limit of normal (ULN). * Total bilirubin \>1.5 × ULN. Exceptions may be made on a case-by-case basis for participants with Gilbert's syndrome in consultation with the Medical Monitor. * Creatinine clearance \<30 mL/min calculated by Cockcroft-Gault formula. * Is currently taking prednisone at a steady dose \>10 mg/day or equivalent (a steady dose ≤10 mg/day is not exclusionary but the individual must be on a stable dose for at least 30 days prior to Visit 2). * Use of any tobacco or combustible cannabis products within 3 months prior to Visit 1 or is unable to refrain from use during the trial. * Has known symptoms of dysphagia, difficulty in swallowing capsules or tablets, or has had a total gastrectomy. * Is currently enrolled in another clinical study (except observational/registry or biobank studies) or has used any investigational drug or device within 90 days prior to Visit 1. * Has ever received stem cell therapy for the treatment of pulmonary fibrosis. * Is currently pregnant, breastfeeding, or is planning to become pregnant during the study. * Has had any prior exposure to LYT-100 or pirfenidone (even one dose).
