Résumé
The European observational, prospective PASSPORT study evaluated the long-term safety of pirfenidone under real-world conditions in idiopathic pulmonary fibrosis (IPF), over up to 2 years following its initiation. The FAS (French Ancillary Study) assessed the clinical outcomes of IPF patients participating in PASSPORT (n = 192). Efficacy data were collected retrospectively and prospectively. The primary efficacy endpoints were: change in percent predicted forced vital capacity (FVC) and change in the distance travelled during the 6-min walk test (6MWD). The mean baseline FVC was 71.7% of predicted value. The mean absolute change in the percentage of predicted FVC was -2.4% and -3.8% at months 12 and 24. The mean change in 6MWD was 8.6 and 3.1 m at months 12 and 24, with a range of 23.4-51.7 m. Acute IPF exacerbation and pulmonary hypertension occurred in 20.0 and 8.4% of patients, respectively. The most common reasons for prematurely discontinuing PASSPORT were adverse drug reactions (ADRs) related to pirfenidone (31.3%), death (11.5%), and disease progression (10.9%). The median progression-free survival was 18.4 months (95% CI 12.9, not estimable). The median exposure was 16.3 months (0.5-28.5). The most frequently reported ADRs leading to pirfenidone discontinuation were decreased weight (4.2%), rash (4.2%), and photosensitivity reactions (3.1%). The efficacy data of FAS are consistent with the efficacy results of published phase III clinical trials in IPF. Approximately one third of IPF patients treated with pirfenidone in real-life settings were still under treatment 2 years after initiation. Safety data are consistent with the known safety profile of pirfenidone.

BACKGROUND
BACKGROUND
The European observational, prospective PASSPORT study evaluated the long-term safety of pirfenidone under real-world conditions in idiopathic pulmonary fibrosis (IPF), over up to 2 years following its initiation.
OBJECTIVES
OBJECTIVE
The FAS (French Ancillary Study) assessed the clinical outcomes of IPF patients participating in PASSPORT (n = 192).
METHODS
METHODS
Efficacy data were collected retrospectively and prospectively. The primary efficacy endpoints were: change in percent predicted forced vital capacity (FVC) and change in the distance travelled during the 6-min walk test (6MWD).
RESULTS
RESULTS
The mean baseline FVC was 71.7% of predicted value. The mean absolute change in the percentage of predicted FVC was -2.4% and -3.8% at months 12 and 24. The mean change in 6MWD was 8.6 and 3.1 m at months 12 and 24, with a range of 23.4-51.7 m. Acute IPF exacerbation and pulmonary hypertension occurred in 20.0 and 8.4% of patients, respectively. The most common reasons for prematurely discontinuing PASSPORT were adverse drug reactions (ADRs) related to pirfenidone (31.3%), death (11.5%), and disease progression (10.9%). The median progression-free survival was 18.4 months (95% CI 12.9, not estimable). The median exposure was 16.3 months (0.5-28.5). The most frequently reported ADRs leading to pirfenidone discontinuation were decreased weight (4.2%), rash (4.2%), and photosensitivity reactions (3.1%).
CONCLUSIONS
CONCLUSIONS
The efficacy data of FAS are consistent with the efficacy results of published phase III clinical trials in IPF. Approximately one third of IPF patients treated with pirfenidone in real-life settings were still under treatment 2 years after initiation. Safety data are consistent with the known safety profile of pirfenidone.
