Study Summary

This phase III trial compares the effect of adding tivozanib to standard therapy pembrolizumab versus pembrolizumab alone for the treatment of patients with high-risk renal cell carcinoma (RCC). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Tivozanib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving pembrolizumab and tivozanib together may work better than pembrolizumab alone in treating patients with RCC.

Primary Outcome

The primary analysis will be a comparison of DFS between the two study arms using a stratified log-rank test. The treatment effect will be estimated with a hazard ratio (HR) and corresponding 95% confidence interval obtained from a stratified Cox model with treatment group (experimental group versus control group) as the explanatory variable. Interim analyses: There will be several futility analyses for the trial. These analyses will employ the linear 20% method proposed by Freidlin, Korn and Gr
