392 Background: In RECORD-1, the oral mTOR inhibitoreverolimus significantly improved PFS compared with placebo in patients with mRCC refractory to 1 or 2 prior VEGFr-TKIs. Here, we provide prospective data from European countries on everolimus use in patients with mRCC after failure of anti-VEGF therapy. Methods: To evaluate the safety and efficacy of everolimus in routine clinical practice, data were pooled from 4 prospective, noninterventional studies conducted in Germany, France, Greece, and Austria. Results: Data from the first 6 months of treatment are available for 534 patients. At baseline, median time since diagnosis of first metastasis from RCC was 1.8 years, and 91% of patients were of favorable or intermediate MSKCC risk prognosis. Predominantly clear cell mRCC was evident in 90% of patients, and most patients had prior nephrectomy (89%). Best overall response by investigator assessment was partial response in 13%, stable disease in 56%, and progressive disease in 32%. Overall, 77% of patients experienced ≥1 adverse event (AE) and 22% experienced ≥1 serious AE. AEs occurring in 〉 5% of patients included stomatitis (25%), anemia (13%), asthenia (9%), fatigue (8%), pneumonitis (8%), rash (8%), diarrhea (7%), decreased appetite (7%), hypertriglyceridemia (6%), dyspnea (6%), nausea (6%), and peripheral edema (5%). Serious AEs occurring in 〉 2% of patients included stomatitis (3.4%), general health deterioration (2.2%), anemia (2.1%), dyspnea (2.1%), and pneumonitis (2.1%). Median everolimus duration was 4.8 months. Treatment was discontinued due to disease progression in 50% of patients and AEs in 24% of patients. A similar proportion of patients had Karnofsky performance status ≥70 at baseline (86%) and at end of analysis (80%). Updated data will be available in February 2012. Conclusions: Preliminary results of this pooled analysis of 4 European studies substantiate the safety of everolimus reported in the pivotal RECORD-1 trial and provide evidence for the effectiveness of everolimus in routine use. The results support the use of everolimus as a standard of care for VEGF-refractory patients with mRCC.
