OBJECTIVE: We attempted to evaluate the feasibility (therapeutic efficacy, tolerance, and clinical courses after treatment) of pirfenidone, an anti-fibrotic drug for patients with chronic pulmonary fibroses such as idiopathic pulmonary fibrosis (IPF). METHODS: Open-label one-year treatment for compassionate-use. PATIENTS OR MATERIALS: Oral pirfenidone (40 mg/kg body weight) was administered to 8 patients with advanced IPF and 2 with interstitial pneumonia associated with diffuse systemic sclerosis. The plasma concentration of the drug was serially followed. Radiographic scores, pulmonary functions, and arterial blood oxygen pressure were compared at three time points: at one-year before treatment, at the time of entry, and at one-year after entry. RESULTS: While pirfenidone did not show a definite therapeutic effect on overall survival (2 years after entry). During one-year treatment, there was no significant deterioration in terms of chest radiographic scores and arterial oxygen pressure, and the drug was well tolerated with minimal adverse effects within the ranges observed in this study, plasma pirfenidone concentrations did not seem to relate to the appearance of adverse effects or differences in therapeutic effects. CONCLUSION: The feasibility of Pirfenidone as a therapeutic drug was confirmed for patients with advanced pulmonary fibrosis.
