Primary Outcome Measures
NameTimeMethod
Number of Participants Experiencing Significant Fluid Retention or Worsening in NYHA Functional Class (FC) up to End-of-treatmentFrom randomization up to End-of-Study (Week 12 + 30 days follow-up) plus 1 calendar day

The main endpoint is the number of participants who had at least one of the following: A) significant fluid retention, defined as increase in body weight at any time by ≥ 5% or ≥ 5 kg from baseline due to fluid overload and/or parenteral administration of diuretics. B) Worsening of NYHA functional class from baseline.

Secondary Outcome Measures
NameTimeMethod
PVR at Rest at Week 12 Expressed as Percent of Baseline PVR at RestFrom randomization up to end of treatment period (Week 12)

Pulmonary vascular resistance (PVR) was assessed at rest by right heart catheterization (RHC).

Change From Baseline to Week 12 in Mean Right Atrial Pressure (mRAP)From randomization up to end of treatment period (Week 12)
Change From Baseline to Week 12 in Pulmonary Artery Wedge Pressure (PAWP)From randomization up to end of treatment period (Week 12)
NT-proBNP at Week 12 Expressed as Percent of Baseline NT-proBNP at RestFrom randomization up to end of treatment period (Week 12)
Change From Baseline to Week 12 in Mean Pulmonary Arterial Pressure (mPAP)From randomization up to end of treatment period (Week 12)
Change From Baseline to Week 12 in Cardiac Index (CI)From randomization up to end of treatment period (Week 12)
Change From Baseline to Week 12 in Diastolic Pulmonary Vascular Pressure Gradient (DPG)From randomization up to end of treatment period (Week 12)
