ABSTRACT: Aim
The efficacy and safety of pirfenidone have been previously demonstrated in patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF). However, the effect of pirfenidone in patients with advanced IPF remains unclear. Here, we investigated the effects of pirfenidone against advanced IPF in a real-world setting.Methods
A prospective nationwide post-marketing study was conducted on 258 patients from 10 Korean institutions. Patients with a predicted forced vital capacity (FVC) less than 50% or a diffusing capacity of the lung for carbon monoxide (DLco) less than 35% at baseline were classified as the advanced IPF group.Results
Of 219 patients included in the analysis, the majority were male (76.3%); the mean age was 67.3 years, and the advanced group accounted for 17.8% of the patients. The median treatment duration was 298 days. Among the subjects, 86.3% experienced adverse events (AEs), of which a decreased appetite (32.4%) and a photosensitivity reaction (13.7%) were the most frequent. The incidence of AEs was similar between the advanced and non-advanced groups (92.3% vs. 85.0%, respectively; p = 0.229). Although the overall discontinuation rate was higher in the advanced group than in the non-advanced group (74.4% vs. 50.0%, respectively; p = 0.006), the percentages of the patients who discontinued treatment as a result of AEs were similar in both groups (20.5% vs. 23.3%, respectively; p = 0.704). In all patients, the rates of decline in the predicted FVC and DLco over 48 weeks were - 4.3 ± 1.3% and - 4.4 ± 1.7%, respectively. There was no between-group difference in the rate of lung function decline.Conclusions
Pirfenidone used for the treatment of patients with IPF in a real-world setting was well tolerated, with an acceptable safety profile and a consistent therapeutic effect, regardless of the disease severity.Trial registration
ClinicalTrials.gov NCT03761082; the trial was retrospectively registered on December 3, 2018.
