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
