Eligible patients must meet all of the following inclusion criteria:
1. Signed informed consent prior to any study-mandated procedure.
2. Patients with symptomatic Pulmonary Arterial Hypertension (PAH) in modified WHO
functional class II to IV.
3. Patients with the following types of PAH belonging to groups 1.1 to 1.3 of the Venice
classification:
a. Idiopathic (IPAH),
b. Familial (FPAH),
c. Related to:
i. Collagen vascular disease
ii. Simple (atrial septal defect, ventricular septal defect, patent ductus
arterious) congenital systemic to pulmonary shunts at least 1 year
post surgical repair
iii. HIV infection
iv. Drugs and toxins
4. PAH diagnosis confirmed by hemodynamic evaluation performed prior to randomization and
showing all of the following:
a. Mean pulmonary artery pressure (mPAP) > 25 mm Hg
b. Pulmonary capillary wedge pressure (PCWP) or left ventricular end diastolic
pressure (LVEDP) = 15 mmHg
c. Pulmonary vascular resistance (PVR) at rest = 320 dyn*sec/cm5
? For patients who participate in the pharmacokinetic/pharmacodynamic substudy,
hemodynamic evaluation must have been performed within 3 months prior to
randomization.
? For all other patients, hemodynamic evaluation must have been performed within
1 year prior to randomization.
5. 6-minute walk distance (6MWD) = 50 m at screening and randomization
The 6MWT performed at screening and randomization must satisfy the following
requirements:
• 6MWT distance must be > 50 m or patient cannot be included in the study.
• 6MWT #2 (at Randomization) distance should be within 10% of 6MWT #1
distance (at Screening) or a third test is required (6MWT #3).
• 6MWT #3 (at Randomization) distance should be within 10% of 6MWT #2
distance or the patient cannot be included in the study.
6. Men or women = 12 years of age:
Only sites that have adequate pediatric pulmonary experience are allowed to enroll
patients between 12 and 17 year of age.
Women of childbearing potential* with a negative serum pre-treatment pregnancy test and who
consistently and correctly use (from screening and up to 28 days after study treatment
discontinuation) a reliable method of contraception with a Pearl index of < 1% (oral hormonal
contraceptive, implant, vaginal hormone ring, or intrauterine system [IUS]). During the entire
study duration and for at least 1 month after last study drug intake, their partner, if not
vasectomised, must use a condom in addition.
*A woman is considered to have childbearing potential unless she meets at least one of the
following criteria:
• previous bilateral salpingo-oophorectomy or hysterectomy
• premature ovarian failure confirmed by a specialist gynaecologist
• pre-pubescence, XY genotype, Turner syndrome, uterine agenesis
• age > 50 years and not treated with any kind of HRT for at least 2 years prior to
screening, with amenorrhea for at least 24 consecutive months prior to screening, and a
serum FSH level of > 40 IU/L at screening

1.PAH associated with portal hypertension, thyroid disorders, glycogen storage disease, Gaucher’s disease, hereditary hemorrhagic telangiectasia, hemoglobinopathies, myeloproliferative disorders or splenectomy.
2.PAH associated with non corrected simple congenital systemic-to-pulmonary shunts, and combined and complex systemic-to-pulmonary shunts, corrected or non corrected.
3.PAH associated with significant venous or capillary involvement (PCWP > 15 mmHg), known pulmonary veno-occlusive disease, and pulmonary capillary hemangiomatosis.

5.Pulmonary Hypertension belonging to groups 2 to 5 of the Venice classification.
6.Moderate to severe obstructive lung disease: forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) < 70% and FEV1 < 65% of predicted value after bronchodilator administration.
7.Moderate to severe restrictive lung disease: total lung capacity (TLC) < 60% of predicted value.
8.Moderate to severe hepatic impairment, i.e., Child-Pugh Class B or C.
9. Estimated Creatinine clearance <30mL/min
10.Serum aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) > 1.5 times the upper limit of normal.
11.Hemoglobin < 75% of the lower limit of the normal range.
12.Systolic blood pressure < 100 mmHg.
13.Acute or chronic physical impairment (other than dyspnea), limiting the ability to comply with study requirements.
14.Pregnant or breast-feeding.
15.Known concomitant life-threatening disease with a life expectancy < 12 months.
16.Body weight < 40 kg.
17.Any condition that prevents compliance with the protocol or adherence to therapy.
18.Recently started (< 8 weeks prior to randomization) or planned cardio-pulmonary rehabilitation program based on exercise.
19.Treatment with endothelin receptor antagonists (ERAs) within 3 months prior to randomization.
20.Systemic treatment within 4 weeks prior to randomization with cyclosporine A or tacrolimus, everolimus, sirolimus (calcineurin or mTOR inhibitors).

22.Known hypersensitivity to drugs of the same class as the study drug, or any of their excipients.
23.Planned treatment, or treatment, with another investigational drug within 1 month prior to randomization.
