Accepts Healthy Volunteers:   No

Selected Inclusion Criteria:

  • Diagnosis of IPF based on modified American Thoracic Society-European respiratory Society (ATS-ERS) guidelines
  • Diagnosis of PH based on the following hemodynamic requirements: mean pulmonary artery pressure (mPAP_ ≥25 mmHg; pulmonary vascular resistance (PVR) >240 dyne.sec/cm5; pulmonary capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure (LVEDP) ≤15 mmHg
  • Forced vital capacity (FVC) ≥40%
  • Able to walk at least 50 meters during two 6 minute walk tests
  • If receiving calcium channel blockers, low dose oral corticosteroids, immunosuppressive, cytoxic, or antifibrotic drugs dose must be stable.

Selected Exclusion Criteria:

  • Surgical lung biopsy diagnosis other than Usual Interstitial Pneumonia
  • Other known cause of interstitial lung disease
  • Evidence of significant obstructive lung disease
  • Recent hospitalization for an acute exacerbation of IPF
  • Recent active pulmonary or upper respiratory tract infection
  • Left ventricular ejection fraction (LVEF) <40%
  • Serum creatinine ≥2.5 mg/dL
  • Requires hemodialysis, peritoneal dialysis or hemofiltration
  • Female subject who is pregnant or breastfeeding
  • Recent treatment for PH with an ERA, phosphodiesterase type 5 (PDE-5) inhibitor, or prostacyclin derivative
  • Recent treatment with high dose oral corticosteroids
  • Recent treatment (within 4 weeks prior to screening)with imatinib mesylate (Gleevec)
  • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) lab value that is greater than 1.5x the upper limit of the normal range (ULN)
  • Discontinued other ERA treatment for any adverse reaction other than those associated with liver function test abnormalities
