Eligibility:

PHASE1
PHASE2
Brief Summary
Under placebo control, the investigators intend to evaluate the effectiveness and safety of anti-inflammatory therapy and/or targeted drug therapy for early treatment of patients with pulmonary arteri...
Detailed Description
Pulmonary arterial hypertension is characterized by decompensated increase of pulmonary artery pressure owing to continuous progression of pulmonary vascular resistance and can ultimately cause right ...
Eligibility Criteria
Inclusion
- Pulmonary artery systolic pressure estimated in the most recent echocardiography examination before screening ≧40mmHg.
- Before the study, subjects received the best traditional pulmonary arterial hypertension(PAH) treatment (such as oral Ca2+ antagonists, oxygen therapy, digoxin, diuretics, and anticoagulants), and no increase, discontinuation, or dose change at least one month before randomization. But it is allowed to stop or adjust anticoagulants, and adjust the therapeutic dose of diuretics.
- The results of echocardiography showed that the systolic and diastolic functions of the left ventricle were normal, and there was no clinically significant left heart disease (such as mitral valve disease).
Exclusion
- Patients who have received endothelin receptor antagonists and anti-inflammatory drugs within 30 days before randomization.
- Patients with changes in the basic PAH treatment within one month before randomization (such as addition/removal of therapeutic drugs or dose adjustment; including but not limited to oxygen, diuretics, digoxin, anticoagulants, immunosuppressants, or Ca2+ antagonists ). But we allows the discontinuation of anticoagulants or change the dose and the change of diuretic dose.
- Patients who diagnosed with other etiology of PAH, such as portal hypertension, pulmonary vein occlusive disease, etc.
- Patients who have a history of left heart disease including ischemic heart disease, myocardial infarction, symptomatic coronary artery disease; or trans-channel radionuclide angiography, angiography, or echocardiography as assessed by mean pulmonary capillary wedge pressure (or left ventricular end diastolic volume) ≥ 15 mmHg or left ventricular ejection fraction ≤ 40%; or systemic hypertension that cannot be effectively controlled, systolic blood pressure\> 160 mmHg or diastolic blood pressure\> 100 mmHg.
- Patients who have a history of lung diseases, including chronic obstructive pulmonary disease, interstitial lung disease, etc.
- Patients who have a history of blood diseases, including a history of coagulation disorders within 6 months before screening.
- Patients who are allergic to two or more drugs or food; or are known to be allergic to one anti-inflammatory drug (steroidal or non-steroidal anti-inflammatory drug).
- Liver function test exceeds or equals 3 times the upper limit of normal or suffering from known Child-Pugh Class C liver disease.
- Patients with chronic renal insufficiency, and the screening creatinine value is greater than 2.5mg/dL (221μmol/L) or need dialysis.
- Patients with other diseases or conditions that can affect the results of the research.
- Patients who participated in other study drugs or medical devices within 30 days before screening.
