REACT expanded-access program in patients with metastatic renal cell carcinoma: real-world data from a European subanalysis.

AIM

RAD001 Expanded Access Clinical Trial (REACT) provided everolimus to patients with metastatic RCC before its commercial availability. This retrospective subgroup analysis evaluated eventual differences, mainly in safety, between the large European population (n = 906; 66.3%) and the overall population (n = 1367).

PATIENTS & METHODS: REACT enrolled patients from 34 countries who received everolimus 10 mg/day until progression/discontinuation or commercial availability.

RESULTS

Baseline characteristics, except race/ethnicity, were similar. Incidences of grade 3/4 adverse events were 50.7/11.3% in the European population and 48.8/12.8% in the overall population. A similar percentage of the European and overall populations achieved stable disease (∼ 51%) and completed treatment (20.6 and 19.7%).

CONCLUSION

These results do not suggest differences for the European population and support everolimus as a worldwide standard of care for VEGFR-refractory metastatic RCC (NCT00655252).
