Pirfenidone is an antifibrotic and anti-inflammatory drug approved to treat IPF in the US, Europe, Canada, Asia, and Australia. In clinical trials, pirfenidone has been shown to slow progression of mild-to-moderate idiopathic pulmonary fibrosis. It is taken by mouth three times a day. 

Study Purpose

Patients are being offered participation in this pirfenidone trial because They have been diagnosed with fibrotic hypersensitivity pneumonitis (FHP), a type of interstitial lung disease (ILD). This is a disease where scarring of lung tissue occurs as the result of inhaling substances called antigens. These antigens can be substances such as molds, chemicals or dust.

Currently over 1400 subjects have been treated with pirfenidone in 15 clinical trials. This drug has been approved by the Food and Drug Administration (FDA) for use in Idiopathic Pulmonary Fibrosis, a different type of ILD, but requires special permission for use in your condition. The use of pirfenidone has not been approved for the treatment of FHP. It is considered experimental treatment in this study.
