New hope for rare lung scarring? small trial tests pirfenidone

This small pilot study looked at whether the drug pirfenidone is safe and effective for people with a specific type of lung scarring (pulmonary fibrosis) linked to MPO antibodies or vasculitis. Seven adults took the drug for a year, and researchers measured changes in lung function and tracked side effects. The goal was to see if the drug could slow or stop the worsening of the disease.
