Trial to Evaluate the Efficacy and Safety of LYT-100 (Deupirfenidone) Compared to Pirfenidone in Adults With Idiopathic Pulmonary Fibrosis (IPF)

Summary

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.

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).
