Objective: To retrospectively analyze the effects of treatment duration on outcomes of everolimus treatment of patients in the RAD001 Expanded-Access Clinical Trial in RCC (REACT) program. Methods: Patients with metastatic renal cell carcinoma refractory to vascular endothelial growth factor receptor-tyrosine kinase inhibitor received everolimus (10 mg once daily), with dosing interruption or modifications allowed for toxicity. All serious and grade 3/4 adverse events and grade 1/2 adverse events leading to a change in drug administration were reported. Tumor response was evaluated using Response Evaluation Criteria In Solid Tumors. Results: The study stratified 1367 evaluable patients into treatment duration groups of <3 months, ≥3 and <6 months, ≥6 months and <1 year, and ≥1 year. Pneumonia, noninfectious pneumonitis, and hyperglycemia occurred more frequently in patients receiving everolimus for ≥1 year but did not result in treatment discontinuations. First occurrence of adverse events presented early in the treatment course for most patients. Treatment duration of ≥6 months was associated with improved disease control rates. Conclusion: Everolimus is well tolerated in patients with metastatic renal cell carcinoma for treatment durations ≥1 year and not associated with cumulative toxicity.
