Design outcomes

Primary

MeasureTime frame
Main Objective: Period 1 primary objectives: For the EU regulatory assessment, the primary objective of Period 1 is to evaluate the efficacy of tadalafil compared with placebo, as measured by time to clinical worsening (CW) in pediatric PAH patients through Week 24. For the United States (US) regulatory assessment, the primary objective of Period 1 is to evaluate the efficacy of tadalafil compared with placebo in improving 6-minute walk distance from bBaseline to Week-24 as assessed in a subset of patients =6 to <18 years of age who are developmentally capable of performing a 6MW test. Period 2 Primary Objective: The primary objective of Period 2 is to evaluate long-term safety of tadalafil while providing continued access to tadalafil for pediatric patients with PAH who participated in Period 1;Secondary Objective: Period 1 secondary objectives: • Assess the efficacy of tadalafil compared with placebo on time to CW (for the US regulatory assessment) and the incidence of CW. • Assess the efficacy of tadalafil compared with placebo on 6-minute walk (6MW) distance in a subset of patients =6 to <18 years of age who are developmentally capable of performing a 6MW test (for the EU regulatory assessment). • Characterize the population PK of tadalafil in pediatric PAH patients. • Assess the safety of tadalafil compared with placebo. Period 2 secondary objectives: • The secondary objective of Period 2 is to evaluate the incidence of, and time to CW;Primary end point(s): For the EU regulatory assessment, the primary endpoint for this study is time to first occurrence of clinical worsening. For the US regulatory assessment, the primary endpoint for this study is 6 minute-walk distance in meters assessed in a subset of patients =6 to <18 years of age who are developmentally capable of performing a 6MW test.;Timepoint(s) of evaluation of this end point: For time to first occurrence of clinical worsening -throughout the duration of the study. For 6 minute-walk distance in

Secondary end point(s): Period 1 •Time to clinical worsening (for the US regulatory assessment) and the incidence of clinical worsening •6 minute walk (MW) distance in meters measured in subset of patients who are =6 to <18 years of age and who are developmentally capable of performing a 6MW test (for the EU regulatory assessment). •Population PK assessment of plasma tadalafil concentrations at steady-state. Period 2 •Incidence of and time to clinical worsening •6MW distance in meters measured in subset of patients who are =6 to <18 years of age and who are developmentally capable of performing a 6MW test. ;Timepoint(s) of evaluation of this end point: For clinical worsening -throughout the duration of the study. For 6 minute-walk distance in meters day 1, weeks 4, 8,12,16, 20, 24,1 year and 2 year. For PK assessment - at weeks 2, 4, 16 and 24.
