Phase III trial of everolimus in metastatic renal cell carcinoma: subgroup analysis of Japanese patients from RECORD-1.

Abstract

OBJECTIVE:

To assess the efficacy and safety of everolimus in Japanese patients with metastatic renal cell carcinoma.

METHODS:

A subgroup analysis of the pivotal Phase III, randomized, double-blind, placebo-controlled trial of everolimus 10 mg/day in patients with disease progression after treatment with sorafenib, sunitinib or both assessed outcomes in Japanese participants. Results were compared with those for the overall study population.

RESULTS:

The final trial analysis included 24 Japanese patients (everolimus, n= 15; placebo, n = 9). Median progression-free survival in the Japanese subpopulation was 5.75 months (95% confidence interval, 4.90 months to not reached) with everolimus and 3.61 months (95% confidence interval, 1.91-9.03 months) with placebo (hazard ratio, 0.19; 95% confidence interval, 0.05-0.83). Median overall survival was not reached with everolimus and was 14.9 months (95% confidence interval, 11.0-16.8 months) with placebo (hazard ratio, 0.30; 95% confidence interval, 0.07-1.27). Overall, efficacy and safety were similar when comparing the Japanese and overall populations. In the Japanese subpopulation, the most common adverse events with everolimus were stomatitis, infections and rash. Four Japanese subjects (27%) developed Grade 1 (n = 2) or 2 (n = 2) pneumonitis (all reversible and allowing for continuation of therapy, after interruption, steroids and dose reduction for both Grade 2 cases), with a lower pneumonitis incidence of 14% in the overall population (albeit associated with a Grade 3 incidence of 4%).

CONCLUSIONS:

These findings suggest that the demonstrated benefits of everolimus in the overall trial population are similar in Japanese patients with metastatic renal cell carcinoma.
