Exclusion criteria
Exclusion criteria: - Patients on a PAH-specific monotherapy targeting the nitric oxide pathway (i.e. PDE-5 inhibitor or sGC stimulator). - Patients treated with prostacyclin, prostacyclin analog or selexipag at any time prior to Day 1. - Any hospitalization during the last 30 days prior to screening (Visit 1). - Severe coronary heart disease or unstable angina. - Documented severe hepatic impairment or severe renal insufficiency at screening (Visit 1). - Participation in a cardio-pulmonary rehabilitation program based on exercise training within 8 weeks prior to screening. - Any factor or condition likely to affect full participation in the study or compliance with the protocol (such as adherence to protocol mandated procedures), as judged by the investigator.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the effect of selexipag on daily life physical activity (DLPA) of patients with pulmonary arterial hypertension (PAH) as assessed by a wearable actigraphy device.;Secondary Objective: • To evaluate the effect of selexipag on PAH symptoms and their impacts in patients’ daily life. • To evaluate the effect of selexipag on exercise capacity, and disease severity in patients with PAH. • To evaluate the safety and tolerability of selexipag in patients with PAH.;Primary end point(s): - Change from baseline to Week 24 / EOT in actigraphy-assessed daily life physical activity (DLPA) as measured by: . Daily time spent (minutes) in non-sedentary activity (> 100 activity counts per minute) . Percentage of daily time spent in non-sedentary activity (> 100 activity counts per minute) . Total DLPA in counts/min . Sleep variables: Total sleep time (minutes); wake after sleep onset (minutes); number of awakenings, sleep efficiency (percentage) ;Timepoint(s) of evaluation of this end point: Up to Week 24 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Change from baseline to Week 24 / EOT for following PAH SYMPACT® domain scores: . Cardiovascular symptom domain score . Cardiopulmonary symptom domain score . Physical impact domain score . Cognitive/emotional impact domain score - Change from baseline to Week 24 / EOT for following variables: . WHO FC . 6MWD . Borg dyspnea index at 6MWT . N-terminal pro b-type natriuretic peptide (NT-proBNP);Timepoint(s) of evaluation of this end point: Up to Week 24 | — |
