E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Effect of the highly potent CYP3A4 inhibitor ritonavir on the pharmacokinetics (PK) of erlotinib, measured as AUC0-24h, AUCmean, Cmax and Cmin |
Vergelijken farmacokinetiek van erlotinib 150mg en erlotinib 75mg+ ritonavir |
|
E.2.2 | Secondary objectives of the trial |
1. Safety of the CYP3A4 moderator ritonavir in combination with erlotinib, which will be measured as the incidence and severity of adverse events with and without ritonavir, according to CTC-AE v4.03. 2. The correlation between the pharmacokinetics, measured as AUC0-24h, AUCmean, Cmax and Cmin of ritonavir and toxicity according to CTC-AE v4.03 3. Study the effect of the highly potent CYP3A4 inhibitor ritonavir on the pharmacokinetics (PK) of the active metabolite of erlotinib, OSI-420 , measured as AUC0-24h, AUCmean, Cmax and Cmin. 4. Quantification of ctDNA, determined with Droplet digital PCR (ddPCR)
