Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: to investigate the pharmacokinetics (PK) of the pediatric formulation of bosentan at doses of 2 mg/kg b.i.d. and 2 mg/kg t.i.d. in children with pulmonary arterial hypertension (PAH) from = 3 months to < 12 years of age.;Secondary Objective: to evaluate efficacy, tolerability, and safety of bosentan in children with PAH from = 3 months to < 12 years of age.;Primary end point(s): The main PK endpoint is defined as the daily exposure to bosentan, i.e., AUC over a period of 24 h (AUC(0-24h)), and calculated as a multiple of the exposure over a dosing interval (AUCt), 3×AUCt and 2xAUCt for three times and two times daily dosing, respectively. ;Timepoint(s) of evaluation of this end point: Not applicable | — |
