Objective: Many studies have shown the efficacy of everolimus after pretreatment with vascular endothelial growth factor receptor-tyrosine kinase inhibitors. We investigated the efficacy and safety of everolimus as a second-line treatment after the failure of vascular endothelial growth factor receptor-tyrosine kinase inhibitor therapy in Japanese patients with advanced renal cell carcinoma. Methods: This was an open-label, multicenter, phase II trial conducted in Japan through the central registration system. A total of 57 patients were enrolled. Patients were administered 10 mg of everolimus q.d. orally. The primary efficacy endpoint was progression-free survival achieved by administration of everolimus. Results: The median progression-free survival of patients administered everolimus was 5.03 months (95% confidence interval: 3.70-6.20). The median overall survival was not reached. The objective response rate was 9.4% (95% confidence interval: 3.1-20.7). The progression-free survival in the group of >100% relative dose intensity was 6.70 months (95% confidence interval: 4.13-11.60), and that in the group of 100% relative dose intensity was 3.77 months (hazard ratio: 2.79, 95% confidence interval: 2.77-5.63). The commonly observed adverse events and laboratory abnormalities were stomatitis (49.1%), hypertriglyceridemia (26.4%), interstitial lung disease (26.4%), anemia (22.6%) and hypercholesterolemia (22.6%) Conclusion: The median progression-free survival was almost similar to that recorded in the RECORD-1 study, whereas prolongation of overall survival was observed in the present study compared with the RECORD-1 study. The treatment outcomes of first-line vascular endothelial growth factor receptor-tyrosine kinase inhibitor therapy and second-line everolimus treatment in Japanese patients were successfully established in the present study.
