Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the study is to confirm the selexipag starting dose(s), selected based on pharmacokinetic (PK) extrapolation from adults, which leads to similar exposures as adult doses in children from = 2 to < 18 years of age, with pulmonary arterial hypertension (PAH), by investigating the PK of selexipag and its active metabolite ACT-333679 in this population.;Secondary Objective: To evaluate the safety and tolerability of selexipag in children from = 2 to < 18 years of age with PAH.;Primary end point(s): Primary pharmacokinetic (PK) endpoint: - Model-based exposure (AUCt,ss, combined) of selexipag and ACT-333679 corrected for their potency, determined during the 12 weeks up-titration period.;Timepoint(s) of evaluation of this end point: - PK sampling at Weeks 1, 2, 4, 6 and 12 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary PK endpoints: - Area under the plasma concentration-time curve over a dose interval at steady state (AUCt,ss), maximum concentration at steady state (Cmax,ss), time to reach Cmax,ss (tmax,ss) for selexipag and ACT-333679, based on non-compartmental analysis (NCA). -Ttrough concentration at steady state (Ctrough, ss) for selexipag and ACT-333679. Safety endpoints • Treatment-emergent AEs (TEAEs), treatment-emergent serious adverse events (TESAEs) and treatment-emergent deaths (all causes), AEs leading to permanent discontinuation of study drug. • Treatment-emergent marked laboratory abnormalities and ECG abnormalities up to EOT+ 3 days. • Change from baseline up to EOT + 3 days in: - selected hematology and blood chemistry laboratory variables. - TSH - Vital signs (blood pressure, heart rate) - Height and body mass index - Sexual maturation (Tanner stage) ;Timepoint(s) of evaluation of this end point: - AUCt,ss, cmax,ss, tmax,ss: PK sampling at Weeks 1, 2, 4, 6 and 12 - Ctrough: PK sampling at Weeks 2, 4,and 6 - TEAEs, TESAEs,treatment emergent deaths and AEs leading to permanent discontinuation: continuously from Day 1 up to 3 days after the end of treatment - Tanner stage: at screening (baseline), Week 16 and every 6 months after the first 12 months - Other safety endpoints: on Day 1 (baseline), Week 12 and Week 16, then every 3 months during the first 12 months and every 6 months thereafter up to the end of treatment visit, with additional timepoints for vital signs (Week 4), ECG (Weeks 1 & 4), laboratory tests (Week 4), TSH (Weeks 4 & 8) | — |
