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.
