Abstract

Data from controlled clinical studies in patients with more advanced idiopathic pulmonary fibrosis (IPF) could inform clinical practice, but they are limited, since this sub-population is usually excluded from clinical trials. These exploratory post-hoc analyses of the open-label, long-term extension study RECAP (NCT00662038) aimed to assess the efficacy and safety of pirfenidone in patients with more advanced IPF. Patients were categorised according to the extent of lung function impairment at baseline: more advanced (percent predicted FVC <50% and/or DLco <35%) and less advanced (percent predicted FVC ≥50% and DLco ≥35%). Overall, 596 patients with baseline FVC and/or DLco values available were included in the analyses; 187 patients had more advanced disease, and 409 patients had less advanced disease. Mean percent predicted FVC declined throughout 180 weeks of treatment in both more and less advanced disease subgroups. Both subgroups exhibited a similar pattern of adverse events; however, adverse events related to IPF progression were experienced by a higher proportion of patients with more advanced versus less advanced disease. Discontinuation rates due to any reason, adverse events related to IPF progression, or deaths were each higher in the more advanced versus the less advanced disease subgroup. These analyses found that longer-term pirfenidone treatment resulted in a similar rate of lung function decline and safety profile in patients with more advanced versus less advanced IPF, and the data suggest that pirfenidone is efficacious, well tolerated, and a feasible treatment option in patients with more advanced IPF.
