简要总结
This phase III trial compares the effect of adding surgery to a standard of care immunotherapy-based drug combination versus a standard of care immunotherapy-based drug combination alone in treating patients with kidney cancer that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as nivolumab, ipilimumab, pembrolizumab, and avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Surgery to remove the kidney, called a nephrectomy, is also considered standard of care; however, doctors who treat kidney cancer do not agree on its benefits. It is not yet known if the addition of surgery to an immunotherapy-based drug combination works better than an immunotherapy-based drug combination alone in treating patients with kidney cancer.
详细描述
PRIMARY OBJECTIVE:
I. To compare overall survival in participants with newly diagnosed metastatic renal cell carcinoma who are randomized to receive immune checkpoint inhibitor-based combination treatment plus cytoreductive nephrectomy versus immune checkpoint inhibitor-based combination treatment alone.
SECONDARY OBJECTIVES:
I. To compare overall survival between arms in the subset who received their assigned protocol treatment.
II. To assess complications of nephrectomy and post-randomization drug toxicities.

结局指标
主要结局
Overall survival
时间窗: From date of randomization to date of death due to any cause, assessed up to 7 years.
Analysis will be intent-to-treat. Evidence suggesting early termination of the trial and a conclusion that the cytoreductive nephrectomy (CN) approach is superior to treatment alone would be if the null hypothesis is rejected at the one-sided 0.005 level. For the second and third interim analyses, the null and alternative hypotheses with respect to survival will be tested, with superiority tested at the one-sided 0.005 level, and futility determined to be met if the (CN versus no CN) hazard ratio is greater than or equal to 1. A proportional hazards model will be fit to estimate the hazard ratio adjusting for the stratification factors as covariates in the model. Will evaluate whether each of the stratification factors are predictive factors of cytoreductive nephrectomy by placing an interaction term corresponding to each stratification factor and treatment arm in the proportional hazards survival model.
