Key inclusion & exclusion criteria
|
Inclusion Criteria :

2. Male or female = 18 and = 75 years of age at screening.
3. Initial PAH diagnosis < 6 months prior to Day 1.
4. Right heart catheterization (RHC) performed between Day -28 and Day 1 (RHC data
obtained at the study site within this time frame, but before the study, i.e., before
signed informed consent, are acceptable), meeting all the following criteria:
- Resting mean pulmonary arterial pressure (mPAP) = 25 mmHg.
- Pulmonary capillary wedge pressure (PCWP) or left ventricular end diastolic
pressure (LVEDP) = 15 mmHg.
- PVR = 400 dyn·sec/cm5 (= 5 Wood units) if PCWP < 12 mmHg OR PVR = 500 dyn·sec/cm5
(= 6.25 Wood units) if PCWP in [12-15] mmHg.
- Negative vasoreactivity test mandatory in idiopathic PAH (at this or a previous
RHC).
5. World Health Organization (WHO) Functional Class (FC) II to III.
6. PAH etiology belonging to one of the following groups:
- Idiopathic.
- Heritable.
- Anorexigens induced.
- Associated with one of the following:
- Connective tissue disease
- Congenital heart disease with simple systemic-to-pulmonary shunt (atrial
septal defect, ventricular septal defect, patent ductus arteriosus) =1 year
after surgical repair
- HIV infection
7. 6MWD = 50 m at screening.
8. Woman of childbearing potential [see definition in Section 4.5.1] must:
- Have a negative serum pregnancy test at the screening visit and a negative urine
pregnancy test at the D1 visit, and
- Agree to perform monthly pregnancy tests up to 30 days after EOT2, and
- Agree to use reliable contraception [defined in Section 4.5.2] from screening up
to 30 days after EOT2. Reliable contraception must be started at least 11 days
prior to Day 1.
Exclusion Criteria:

phosphodiesterase-5 inhibitors (PDE-5i), soluble guanylate cyclase stimulator,
prostacyclin, prostacyclin analog, or prostacyclin receptor agonist] at any time prior
to Day 1 (single-dose administration for vasoreactivity testing is permitted; previous
iloprost used intermittently for the treatment of digital ulcers or Raynaud's
phenomenon is permitted if stopped > 6 months prior to Day 1).
2. Subjects who changed the dose or discontinued calcium channel blockers within 1 week
prior to Day 1.
3. Initiation of diuretics within 1 week prior to RCH.
4. Subjects on oral diuretics in whom the dose has not been stable for at least 1 week
prior to RHC.
5. Treatment with other PDE-5i for erectile dysfunction.
6. Treatment with strong inducers of CYP3A4 (e.g., carbamazepine, rifampin, rifampicin,
rifabutin, rifapentin, phenobarbital, phenytoin, and St. John's wort) = 28 days prior
to Day 1.
7. Treatment with strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole,
voriconazole, clarithromycin, telithromycin, nefazodone, ritonavir, boceprevir,
telaprevir, saquinavir, lopinavir, fosamprenavir, darunavir, tipranavir, atazanavir,
nelfinavir, amprenavir, indinavir) = 28 days prior to Day 1.
8. History of priapism.
9. Significant aortic and mitral valve disease requiring a specific treatment.
10. Pericardial constriction.
11. Life-threatening arrhythmia.
12. Uncontrolled hypertension.
13. Symptomatic coronary artery disease.
14. Cardio-pulmonary rehabilitation program based on exercise (planned, or started = 12
weeks prior to Day 1).
15. Body mass index (BMI) > 40 kg/m2 at screening.
16. Acute myocardial infarction = 12 weeks prior to Day 1.

19. Ongoing or planned treatment with nitrates and/or doxazosin.
20. DLCO < 40% of predicted value (eligible only if no sign of veno-occlusive disease
according to adjudication committee);
21. Presence of = 1 of the following signs of relevant lung disease at any time prior to
Day 1:

> 3 x ULN accompanied by AST > ULN (assessed by central laboratory at screening)
and/or Child-Pugh Class C.
26. Serum AST and/or ALT > 3 x ULN (assessed by central laboratory at screening).
27. Porto-pulmonary hypertension.
28. Hemoglobin < 100 g/L assessed by central laboratory at screening.
29. Hypersensitivity to any active substance or excipient of macitentan or tadalafil
formulation.
