E.5 End points |
E.5.1 | Primary end point(s) |
The primary aim is to show a difference in everolimus exposure (AUC0-24hr) of at least 25% in elderly patients (≥70 years) and obese patients (BMI ≥ 30 kg/m2) compared to the control group ( ≤ 70 years ; BMI ≤ 30 kg/m2), after reaching steady state everolimus pharmacokinetics (day 14, but at least after 7 days of everolimus therapy). |
De primaire uitkomstmaat is het vinden van een verschil in everolimus blootstelling (AUC0-24hr) van minimaal 25% in ouderen (≥70 jaar oud) en/of obese patienten (BMI ≥ 30 kg/m2) ten opzichte van controle patienten( ≤ 70 jaar EN BMI ≤ 30 kg/m2). Dit wordt gemeten na het bereiken van steady state everolimus farmacokinetiek op dag 14. |
