Background: Everolimus is approved for treatment of anti-vascular endothelial growth factor (VEGF)-refractory patients with metastatic renal cell carcinoma (mRCC). Clinical trials rarely mirror treatment reality. Thus, a broader evaluation of everolimus is valuable for routine use. Patients and Methods: A German multicenter non-interventional study documented mRCC patients starting everolimus after failure of initial VEGF-targeted therapy. Primary endpoint was effectiveness, defined as time to progression (TIP) according to investigator assessment (time from first dose to progression). Results: Of 382 documented patients, 196 were included in this interim analysis. In the efficacy population (n = 165), median TIP was 7.0 months (95% confidence interval (Cl) 5.1-9.0). Among patients with < or >= 6 months of previous VEGF-targeted therapy, median TIP was 6.6 months (95% Cl 3.8-not estimable) and 7.4 months (95% CI 4.6-9.6), respectively. Most common adverse events were anemia (13%) and dyspnea (14%). Physicians assessed high tolerance and documented high adherence to everolimus therapy (approximately 97%). Conclusion: In routine clinical practice, everolimus is effective, as measured by median TIP (longer than median progression-free survival in RECORD-1 trial), and well tolerated. Our results support everolimus use in anti-VEGF-refractory patients with mRCC.
