Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. To determine the influence of the fatty beverage Cow’s milk, concomitantly taken with erlotinib alone, on erlotinib plasma pharmacokinetics (AUC) compared to erlotinib alone concomitantly taken with water in NSCLC patients. 2. To determine the influence of the fatty beverage Cow’s milk, concomitantly taken with erlotinib and a PPI, on erlotinib plasma pharmacokinetics (AUC) compared to erlotinib and a PPI concomitantly taken with water in cancer patients. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Other pharmacokinetic outcomes (i.e. clearance, maximum concentration (Cmax) and time to Cmax (tmax)). 2. To evaluate the incidence and severity of side-effects of treatment with erlotinib in absence and presence of esomeprazole | — |
