Methods A total of 24 patients with advanced breast cancer n 6 gastric cancer n 6 non-small cell lung cancer n 6 or renal cell carcinoma n 6 who were refractory to unsuitable for standard therapy were randomized 1 1 to oral everolimus 5 or 10 mg day. Primary end points were pharmacokinetic parameters and safety and tolerability. Pharmacokinetic 24-h profiles were measured on day 15 trough level was measured on days 2 8 15 16 and 22. Tolerability was assessed continuously. This final analysis was performed after all patients had received 6 months of study drug or had discontinued. Results Everolimus was absorbed rapidly median Tmax was 3 h range 1-4 and 2 h range in the 5 and 10 mg day groups respectively. Pharmacokinetic parameters increased dose proportionally from the 5 and 10 mg day doses. Steady-state levels were achieved by day 8 or earlier. The most common adverse events suspected to be related to everolimus therapy were increased blood glucose and and fatigue and in the everolimus 5 and 10 mg day dose cohorts respectively. Best tumor response was stable disease in 10 83 and 6 50 patients in the 5 and 10 mg day groups respectively. Conclusions Everolimus 5 or 10 mg day was well tolerated in Chinese patients with advanced solid .
