Summary

This Phase 3 trial tests whether pirfenidone capsules can improve lung function in 272 people with pneumoconiosis, a lung disease caused by inhaling dust. Participants take the drug or a placebo three times daily for a year. The main goal is to see if lung function (measured by FVC) improves or stabilizes.

What this could lead to
If it works, this could provide a treatment option to slow lung function decline in people with pneumoconiosis.
