Brief summary

Pulmonary vascular resistance (PVR) at rest at week 16 expressed as a percentage of the baseline resting PVR.

Detailed description

Change from baseline to week 16 in : - 6-min walk distance (6MWD) - World Health Organisation (WHO) functional class (FC) and Borg dyspnea score - N-terminal pro-brain natriuretic peptide (NT-proBNP) level - Quality of life EQ-5D-3L scale., Change from baseline to week 42 in : - 6MWD - WHO FC and Borg dyspnea score - NT proBNP level - Quality of life EQ-5D-3L scale., Change from baseline to week 42 in PVR., Percentage of subjects reaching PVR<240 dyn.sec.cm-5 at week 42., Frequency and type of BPA procedure-related complications from BPA procedure to end-of-study., Time from randomization to the first PH-related disease progression event up to end-of-study, defined as any of the following : - Death (all causes) - Need for lung transplantation - Hospitalization due to PH - Initiation of parenteral prostanoid therapy due to PH-related disease progression - Clinical worsening defined as a post-baseline decrease in 6MWD by ≥ 15 % combined with WHO FC III or IV)., Change from baseline to week 29 in : - 6MWD - WHO FC and Borg dyspnea score - NT proBNP level - Quality of life EQ-5D-3L scale.
