SBRT (Stereotactic Body Radiation Therapy) in Combination With Nivolumab/Ipilimumab in Renal Cell Carcinoma (RCC) / Kidney Cancer Patients — RADVAX  

Kidney Cancer Clinical Trial

Official title: Phase II Trial of Stereotactic Body Radiation Therapy in Combination With Nivolumab Plus Ipilimumab in Patients With Metastatic Renal Cell Cancer

Status Completed

Clinical Trial Summary

This is a multi-institution, single-arm phase II study to determine the safety and efficacy of SBRT (up to 2 metastatic sites preferentially lung, mediastinum or bone in combination of nivolumab and ipilimumab in patients with metastatic renal cell carcinoma(with a clear-cell component and at least 1 measurable metastatic lesion that is not being irradiated).

Clinical Trial Description

The study is planned based on a two-stage design that allows early termination for lack of efficacy. A safety run-in phase will be included comprising the first 6 patients at minimum to ensure that the combination of nivolumab plus ipilimumab and SBRT is safe. Then, the investigators will determine whether the combination of nivolumab plus ipilimumab and SBRT yields a clinically compelling antitumor activity measured as objective response rate (ORR), and evaluate other endpoints including Thrombotic thrombocytopenic purpura (TTP), duration of response (DOR), progression free survival (PFS), overall survival (OS) and local control of irradiated sites.

There is no previous experience with SBRT used concurrently with nivolumab and ipilimumab in this study population. Therefore, to ensure that the combination is safe, the first six patients will be treated and observed for toxicity for 6 weeks after radiation before continuing with further accrual. Therefore, six patients will be enrolled at the proposed dose of nivolumab and ipilimumab in combination with SBRT. If 4 out of the first 6 patients experience Grade 3/4 toxicity or a lower grade toxicity requiring immune suppressive therapy during the safety run-in observation period (defined as the first 4-cycles, 12 weeks), enrollment will cease and the study will be halted until further safety analysis of the combination regimen can be performed. If less than 4 out of the first 6 patients experience Grade 3/4 toxicities or require steroids, the investigators will proceed with additional accrual with this regimen. ;
