Primary Outcome Measures
NameTimeMethod
Main Objective: The primary objective of this trial is to study the effect of the moderate CYP3A4 inhibitor erythromycin on the pharmacokinetics of palbociclib, measured as AUC0-24h, Cmax and Cmin.;Secondary Objective: The secondary objective of this trial is to compare the incidence and severity of adverse events with (a week) and without co-administration of the moderate CYP3A4 inhibitor erythromycin, according to CTC-AE v5.0;Primary end point(s): The effect of the moderate CYP3A4 inhibitor erythromycin on the pharmacokinetics of palbociclib, measured as AUC0-24h, Cmax and Cmin.;Timepoint(s) of evaluation of this end point: At Day 7 and Day 21 of the trial
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): The incidence and severity of adverse events with (a week) and without co-administration of the moderate CYP3A4 inhibitor erythromycin, according to CTC-AE v5.0;Timepoint(s) of evaluation of this end point: At Day 7 and Day 21 of the trial
