The purpose of this study is to evaluate the efficacy and safety of pirfenidone in participants with fibrosing interstitial lung disease (ILD) who cannot be classified with moderate or high confidence into any other category of fibrosing ILD by multidisciplinary team (MDT) review ("unclassifiable" ILD).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age \>= 18-85 years
* Confirmed fibrosing ILD which, following multidisciplinary team review, cannot be classified with either high or moderate confidence as a specific idiopathic interstitial pneumonia or other defined ILD
* Progressive disease as considered by the investigator as participants deterioration within the last 6 months, which is defined as a rate of decline in forced vital capacity (FVC) \>5% or a significant symptomatic worsening not due to cardiac, pulmonary vascular or other causes
* Extent of fibrosis \>10% on high-resolution computed tomography
* Forced vital capacity \>= 45% of predicted value
* Diffusing capacity of the lung for carbon monoxide (DLco) \>= 30% of predicted value
* Forced expiratory volume in 1 second/FVC ratio \>= 0.7
* Able to do 6-minute walk distance (6MWD) \>= 150 meters
* For women of childbearing potential: agreement to remain abstinent or use a non-hormonal or hormonal contraceptive method with a failure rate of \< 1% per year during the treatment period and for at least 90 days after the last dose of pirfenidone
* For men, agreement to remain abstinent or use contraceptive measures, and agreement to refrain from donating sperm
Exclusion Criteria:
* Diagnosis with moderate or high confidence of nonspecific interstitial pneumonia and any ILD with an identifiable cause such as connective tissue disease-ILD, chronic hypersensitivity pneumonitis, or others
* Diagnosis of idiopathic pulmonary fibrosis independent…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
