简要总结
The purposes of this study are to assess the efficacy of treatment with pirfenidone 2403 milligrams per day compared with placebo in patients with idiopathic pulmonary fibrosis (IPF)and to assess the safety of treatment with pirfenidone 2403 milligrams per day compared with placebo in patients with idiopathic pulmonary fibrosis.
详细描述
This is a Phase 3, randomized, double-blind, placebo-controlled, safety and efficacy study of pirfenidone in patients with idiopathic pulmonary fibrosis (IPF). Approximately 320 patients at approximately 50 centers will be randomly assigned (1:1) to receive pirfenidone 2403 milligrams or placebo equivalent administered in divided doses three times per day (TID) with food. The primary outcome variable will be the absolute change in percent predicted Forced Vital Capacity from Baseline to Week 72. Patients will be randomized by geographic region.
Patients will receive blinded study treatment from the time of randomization until the last patient randomized has been treated for 72 weeks. A Data Monitoring Committee (DMC) will periodically review safety and efficacy data to ensure patient safety.
After week 72, patients who meet the Progression of Disease (POD) definition, which is a ≥ 10% absolute decrease in percent predicted Forced Vital Capacity or a ≥ 15% absolute decrease in percent predicted carbon monoxide diffusing capacity (DLco), will be eligible to receive permitted idiopathic pulmonary fibrosis therapies in addition to their blinded study drug. Permitted idiopathic pulmonary therapies include corticosteroids, azathioprine, cyclophosphamide and N-acetyl-cysteine (with restrictions).

结局指标
主要结局
Absolute Change in Percent Predicted Forced Vital Capacity(FVC)
时间窗: Baseline to week 72
Mean Change in Percent Predicted Forced Vital Capacity (FVC) as measured from baseline to week 72. It is calculated as the simple difference between baseline Percent Predicted FVC measurements and week 72 Percent Predicted FVC measurements.
次要结局
- Categorical Assessment of Absolute Change in Percent Predicted Forced Vital Capacity(Baseline to week 72)
- Progression-free Survival(Baseline to Week 72)
- Change in the Six-Minute Walk Test (6MWT) Distance(Baseline to Week 72)
- Change in Worst Oxygen Saturation by Pulse Oximetry (SpO2) Measurement Observed During the 6-Minute Walk Test(Baseline to Week 72)
- Change in Percent Predicted Hemoglobin (Hb)-Corrected Carbon Monoxide Diffusing Capacity (DLco) of the Lungs(Baseline to Week 72)
- Change in Dyspnea Score(Baseline to Week 72)
- Worsening of IPF(Time to acute IPF exacerbation, IPF-related death, lung transplant or respiratory hospitalization, whichever comes first.)
