Abstract
Aim: To quantify the effect of food on the systemic exposure of lapatinib at steady state when administered 1 h before and after meals, and to observe the safety and tolerability of lapatinib under these conditions in patients with advanced solid tumours. Methods: This was a three-treatment, randomised, three-sequence cross-over study. Lapatinib was administered 1 h after a low- [B] or a high-fat [C] meal and systemic exposure was compared with that obtained following administration 1 h before a low-fat meal [A]. Results: In total, 25 patients were included, of whom 12 were evaluable for the pharmacokinetic analysis. Both low-fat and high-fat meals affected lapatinib exposure. Lapatinib AUC0-24 increased following lapatinib administration 1 h after a low-fat meal by 1.80-fold (90 % CI: 1.37-2.37) and after a high-fat meal by 2.61-fold (90 % CI: 1.98-3.43). Lapatinib Cmax increased following lapatinib administration 1 h after a low-fat meal by 1.90-fold (90 % CI: 1.49-2.43) and after a high-fat meal by 2.66-fold (90 % CI: 2.08-3.41). The most commonly occurring treatment-related toxicity was diarrhoea (8/25, 32 % CTCAE grade 1 and 2/25, 8 % grade 2) and one treatment-related grade≥3 event occurred (fatigue grade 3, 4 %). Conclusions: Both low-fat and high-fat food consumed 1 h before lapatinib administration increased lapatinib systemic exposure compared with lapatinib administration 1 h before a low-fat meal. In order to administer lapatinib in a fasted state, it is advised to administer the drug 1 h before a meal.
