Brief summary
The purpose of this study is to determine whether aprepitant can be used in the Cisplatin - Etoposide chemotherapeutic regimen.
Detailed description
Aprepitant acts initially as a moderate inhibitor of CYP3A4 followed by a short period of CYP3A4 induction. Etoposide is a substrate of CYP3A4 and may therefore be suvject to a drug interaction with aprepitant. CE can be classified as a highly emetogenic chemotherapeutic regimen and the use of aprepitant may therefore be considered when no clinically relevant drug interaction with etoposide can be determined.
Interventions
125mg on Day 1; 80mg on Day 2-3 during CE cycle. Dexamethasone is added as well.
Standard anti-emetic regimen during CE treatment
