- Relative Change From Baseline to Week 12 in Pulmonary Vascular Resistance (PVR). [ Time Frame: From enrollment/baseline to Week 12 in the Double Blind (DB) treatment period ]The relative change from baseline to Week 12 in PVR is expressed as a ratio of Week 12 to baseline PVR.
- Change From Baseline to Week 12 in 6-minute Walk Distance (6MWD) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]The purpose of the six minute walk is to test exercise tolerance and capacity. The test measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes.
- Change From Baseline to Week 12 in WHO Functional Class (FC) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]Changes from baseline to Week 12 in WHO FC were dichotomized as worsening (i.e., change > 0) versus no change or improvement (i.e., change ≤ 0). Class I: no symptoms with exercise or at rest. No limitation of activity. Class II: No symptoms at rest but slight limitation with ordinary activities causing symptoms (e.g. short of breath with climbing a flight of stairs, grocery shopping, or making the bed). Class III: may not have symptoms at rest but activities greatly limited by shortness of breath, fatigue, or near fainting. Class IV: symptoms at rest (e.g. dyspnea and/or fatigue) and inability to carry out any physical activity without symptoms. Patients in class IV manifest signs of right heart failure.
- Change From Baseline to Week 12 in the Biomarker N-terminal Pro B-type Natriuretic Peptide (NT-proBNP) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]NT-proBNP functions as a strong indicator of prognosis in patients with pulmonary hypertension (PH). The relative change from baseline to Week 12 in NT-proBNP is expressed as a ratio of Week 12 to baseline NT-proBNP.
- Change From Baseline to Week 12 in Mean Right Atrial Pressure (mRAP) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]mRAP is the mean blood pressure in the right atrium of the heart.
- Change From Baseline to Week 12 in Mean Pulmonary Artery Pressure (mPAP) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]mPAP is the mean blood pressure inside the pulmonary artery which moves the blood from the heart to the lungs. Monitoring of mPAP can detect small changes in the function of the heart.
- Change From Baseline to Week 12 in Cardiac Index [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]The cardiac index is an assessment of the function of the heart and relates the cardiac output to the patient's body size (the patient's body surface area).
- Change From Baseline to Week 12 in Total Pulmonary Resistance (TPR) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]TPR is the resistance the pulmonary circulation that must be overcome in order for the blood flow to occur. It takes into account the blood pressure in the pulmonary arteries and the cardiac output. It is an important measurement to monitor the function of the pulmonary circulation and detect disease progression or improvement.
- Change From Baseline to Week 12 in Mixed Venous Oxygen Saturation (SVO2) [ Time Frame: From enrollment/baseline to Week 12 in the DB treatment period ]SVO2 help assess tissue oxygen delivery. It describes the percentage of oxygen bound to hemoglobin in the blood which returns to the heart. This reflects the amount of residual oxygen in the blood after oxygen extraction by the tissues throughout the body.
