Inclusion Criteria

• Male and female patients 18 years of age or older with symptomatic PAH.
• Subjects with PAH belonging to one of the following subgroups of the Updated Clinical Classification Group 1 (Nice, 2013):
• Idiopathic PAH
• familial PAH
• PAH associated with connective tissue disease, congenital heart disease (surgically repaired at least 12 months prior to screening) or drug or toxin induced (for example, anorexigen use).
• Subjects must have persistent symptoms due to PAH despite therapy with at least one of
the following PAH medications: an endothelin receptor antagonist, asoluble guanylate cyclase stimulator or a phosphodiesterase inhibitor. The subjects' PAH medication regimen, with typical medications including calcium channel blockers, endothelin receptor antagonists, soluble guanylate cyclase stimulators and/or phosphodiesterase inhibitors, must have been used at a stable dose and frequency for at least 12 weeks before the screening visit and during the screening period.
• Diagnosis of PAH established according to the standard criteria before the screening visit:
• Resting mean pulmonary arterial pressure = 25 mmHg.
• PVR > 240 dynes s/cm5.
• Pulmonary capillary wedge pressure or left ventricular end diastolic pressure = 15 mmHg
• PVR > 400 dynes s/cm5 at the time of the baseline right heart catheterization (RHC) (if a RHC was completed within one month of the screening visit, that result may be used for inclusion).
• 6-minute walk distance greater than 150 meters at Screening. This distance must be confirmed by a second 6MWT prior to randomization. The value of the second 6MWD should be within ± 15% of the value obtained at Screening.
Other protocol-defined inclusion criteria may apply.

Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 34
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 4

Exclusion Criteria

• Subjects with clinically unstable right heart failure within the last three months (New York Heart Association (NYHA) Class IV).
• Subjects with PAH associated with portal hypertension, Human Immunodeficiency Virus
(HIV) infection or unrepaired congenital systemic to pulmonary shunts or subjects with PAH responsive to high dose calcium channel blockers.
• Subjects who have received or have been scheduled to receive long-term treatment with
epoprostenol or any prostacyclin within the three months prior to the screening visit or during the screening period.
• Hypotensive subjects (systemic systolic blood pressure < 85 mmHg)
• Subjects with left sided heart disease, chronic left sided heart failure, congenital or acquired valvular disease and/or pulmonary venous hypertension, as determined by history or echocardiogram at baseline visit.
• Subjects with obstructive (FEV1/ FVC < 70% predicted and FEV1 < 70% predicted) or restrictive (total lung capacity < 65% predicted and/or clinically significant abnormality on CXR) lung disease at screening.

Other protocol-defined exclusion criterias may apply.
