Chronic heart failure with NYHA class III/IV or known left ventricular ejection fraction < 25%. 12. Moderate to severe hepatic impairment, i.e., Child-Pugh Class B or C. 13. Estimated creatinine clearance < 30 mL/min. 14. Serum aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) > 1.5 times the upper limit of normal. 15. Hemoglobin < 75% of the lower limit of the normal range. 16. Systolic blood pressure < 100 mmHg. 17. Pregnant or breast-feeding. 18. Current drug or alcohol dependence. 19. Chronic treatment with the following drugs (within 4 weeks of randomization): - Oral corticosteroids (> 20 mg/day of prednisone or equivalent), - Immunosuppressive or cytotoxic drugs including cyclophosphamide and azathioprine, - Antifibrotic drugs including pirfenidone, D-penicillamine, colchicine, TNFα blocker, imatinib and interferon γ, - Chronic use of N-acetylcysteine prescribed for IPF (> 600 mg/day). 20. Oral anticoagulants other than those indicated for a venous or arterial thrombotic disease within 4 weeks prior to randomization. 21. Treatment with endothelin receptor antagonists (ERAs) within 4 weeks prior to randomization. 22. Previous participation in the BUILD-3 (Bosentan Use in Interstitial Lung Disease) study within 6 months prior to randomization. 23. Systemic treatment within 4 weeks prior to randomization with cyclosporine A or tacrolimus, everolimus, sirolimus (calcineurin or mTOR inhibitors). 24. Treatment with CYP3A inducers within 4 weeks prior to randomization. 25. Known hypersensitivity to drugs of the same class as the study drug, or any of their excipients. 26. Planned treatment, or treatment, with another investigational drug within 4 weeks prior to randomization.

E.5 End points |
E.5.1 | Primary end point(s) |
Primary Endpoint Change from baseline to end of Period 1 in Forced Vital Capacity (FVC). A mean difference from placebo of at least 0.1 liter is to be detected. This parameter is expected to be normally distributed with a standard deviation of 0.2 liter. Secondary Endpoint Time to occurrence of disease worsening or death up to EOS. Disease worsening is defined as (i) worsening of PFTs or (ii) acute respiratory decompensation of IPF. (i) Worsening of PFTs (confirmed by two tests at least 4 weeks apart) is defined as the occurrence of both: Decrease from baseline ≥ 10% in FVC (absolute values, i.e., liters) and Decrease from baseline ≥ 15% in DLCO (absolute values, i.e., ml•mmHg-1•min-1) A patient unable to perform PFTs at a planned visit due to worsening of IPF will be considered as having a worsening of PFTs if this is not invalidated by a test at a follow-up visit. (ii) Acute respiratory decompensation of IPF is defined as: An unexplained rapid deterioration of patient’s condition within 4 weeks with an increasing shortness of breath requiring oxygen supplementation ≥ 5 liters/min to maintain a resting SaO2 ≥ 90% or PaO2 ≥ 55 mmHg (sea level) or 50 mmHg (high altitude). A documented acute respiratory decompensation of IPF will be considered to be an event, irrespective of the results of any follow-up PFTs or fatal outcome. Patients who are transplanted (without a prior documented disease worsening), or who withdraw their consent, or those lost to follow-up before the EOS will be censored. Patients starting forbidden IPF medications (without prior documented disease worsening as defined above) will not be considered as having IPF worsening. Exploratory endpoints • Time to death (all causes) up to End-of-Study. • Time to occurrence of disease worsening up to EOS. • Proportion of patients who experienced either disease worsening or death at End-of-Period 1. • Transition dyspnea index (TDI) at End-of-Period 1 and EOS. • Proportion of patients who improve in TDI with at least 1 unit at End-of-Period 1 and EOS. • Change from baseline to 4 months, 8 months, End-of-Period 1, EOT and EOS in PFTs (FEV1, FVC, DLCO). • Change from Baseline to Month 4, End-of-Period 1, EOT and EOS in Quality of Life assessed by the SF-36 questionnaire (individual domains and summary component scores). • Change from Baseline to Month 4, End-of-Period 1, EOT and EOS in the Composite Physiologic Index (CPI) |
