Primary Outcome Measures:
  • Time to first adjudicated morbidity or mortality event (up to 7 days after last study-drug intake) [ Time Frame: Baseline (day 1) to over a period of up to 4.3 years ] [ Designated as safety issue: Yes ]

    defined as

    • Death or
    • Hospitalization for worsening of PAH or
    • Worsening of PAH resulting in need for lung transplantation or balloon atrial septostomy or
    • Initiation of parenteral prostanoid therapy or chronic oxygen therapy or
    • Disease progression

Secondary Outcome Measures:
  • Evaluate the effect of ACT-293987 on exercise capacity (6-minute walk distance & Borg dyspnea index) & other secondary & exploratory efficacy endpoints in patients with PAH [ Time Frame: Baseline (day 1) to over a period of up to 4.3 years ] [ Designated as safety issue: Yes ]
