Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: • Histological or cytological proof of cancer for which palbociclib is considered standard care; • Age >= 18 years; • WHO performance status of 0, 1 or 2; • Adequate organ function per judgement of the treating physician; • Able and willing to undergo blood sampling for PK analysis.

Exclusion criteria

Exclusion criteria: • Concomitant use of medication(s) which could influence the pharmacokinetics of palbociclib within 14 days or five half-lives of the drug (whichever is shorter) before start of the study, consisting of (but not limited to) CYP3A4-inhibitors/inductors • Women who are pregnant or breast feeding; • Patients with known alcoholism, drug addiction and/or psychiatric of physiological condition which in the opinion of the investigator would impair study compliance; • Palbociclib related side effects that would require a dose reduction per judgement of the treating physician; • QT duration corrected for heart rate > 450 ms or > 480 ms for subjects with bundle branch block.

Design outcomes

Primary

MeasureTime frame
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

MeasureTime frame
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.
