Who can take part

You may be able to join if

  • Documented clinical diagnosis of PAH (Group 1 PH according to the 7th World Symposium on Pulmonary Hypertension (WSPH))
  • WHO functional class II or III (slight to marked limitation of functional status due to PAH)
  • Receiving background Standard Of Care (SOC) therapy for PAH on a stable dose and regimen, as determined by the investigator, as described in the protocol
  • PVR ≥400 dynes∙sec/cm^5 (5 Wood units) based on Right Heart Catheterization (RHC) during the screening period
  • Has 6MWD ≥150 and ≤550 meters repeated twice during screening as described in the protocol
  • Note: Other protocol-defined inclusion criteria apply

You likely can't join if

  • Has Group 2 (PH associated with left heart disease), Group 3 (PH associated with lung diseases and/or hypoxia), Group 4 (PH associated with pulmonary artery obstructions), or Group 5 (PH with unclear and/or multifactorial mechanisms) PH according to the 7th WSPH
  • Note: Other protocol-defined exclusion criteria apply
  • Pulmonary Arterial Wedge Pressure (PAWP) >15 mm Hg by RHC during the screening period
  • History of left-sided heart disease and/or clinically significant cardiac disease, as described in the protocol
  • Obstructive lung disease defined as Forced Expiratory Volume in 1 second (FEV1)/Forced Vital Capacity <0.7 and FEV1 <70% of the predicted value as described in the protocol
  • Evidence of interstitial lung disease as defined in the protocol
