Key inclusion & exclusion criteria
|
Inclusion Criteria:
1. Signed and dated informed consent document
2. Able to comply with study procedures
3. Diagnosis of PAH as classified by:
1. Idiopathic (IPAH) or heritable(HPAH); or
2. PAH associated with CTD; Systemic Sclerosis, Limited Scleroderma, Mixed, SLE, or
overlap syndrome;
3. PAH associated with HIV ii. Simple, congenital shunts at least one year post
repair. iii. Exposure to legal drugs, chemicals and toxins
4. Cardiac catheterization prior to Screening with:
1. mPAP = 25 mmHg (at rest);
2. PCWP = 15 mmHg; and
3. PVR > 3 mmHg/L/min or 240 dyn.sec/cm5
5. A qualification cardiac catheterization, to confirm the persistence and severity of
PAH, if the diagnostic catheterization was performed more than 30 days prior to
Baseline
1. Confirms diagnosis;
2. PVR above 300 dyn.sec/cm5 to demonstrate the persistence and severity of PAH;
and
3. No change in disease-specific PAH therapy since the qualification
catheterization used
6. Newly diagnosed PAH on no disease-specific PAH therapy or previously diagnosed on
oral disease-specific PAH therapy for 90 days prior with either an ETRA and/or PDE-5i
7. Has PFTs within 180 days prior to Baseline with no evidence of significant
parenchymal lung disease defined as:
- FEV1 = 70% (predicted) (pre-bronchodilators);
- FEV1/FVC = 70% (pre-bronchodilators); or
- Total lung capacity < 70% (predicted).
8. Has WHO/NYHA FC II- IV.
9. = 18 and = 75 years.
10. Weight = 40 kg.
11. Has 6MWT distance at least 50 meters.
12. Had a V/Q scan or pulmonary angiogram prior to Screening that shows no evidence of
thromboembolic disease
13. If on the following: vasodilators (including calcium channel blockers), digoxin,
spironolactone, or L-Arginine; must be on a stable dose 30 days prior to Baseline and
maintained throughout the study
14. If on corticosteroids, has been receiving a stable dose of = 20 mg/day of prednisone
(or equivalent dose, if other corticosteroid) for at least 30 days
15. Women of childbearing potential must be using at least one form of medically
acceptable contraception. Women who are surgically sterile or those who are
post-menopausal for at least 2 years are not considered to be of childbearing
potential. Men who are not sterile must also agree to use contraception
