This is a phase II study to assess the safety and efficacy of the combination of nivolumab with ipilimumab and cabozantinib in patients with untreated brain metastases from RCC until disease progression or intolerable toxicities or patient withdrawal. We will accrue a total of 40 patients. Patients will be treated with nivolumab (3mg/kg) and ipilimumab (1mg/kg) IV every 3 weeks for 4 doses and cabozantinib 40mg daily. Then patients will be treated with nivolumab 480mg IV Q 4 weeks and cabozantinib 40mg daily until progression or intolerable toxicities or patient's withdrawal. A lead-in group of 6 patients will be closely monitored for DLT. If stopping criteria (>3 patients develop DLTs) is met then, treatment will be switched to Nivolumab plus Cabozantinib omitting ipilimumab.
