Phase 1

Recruiting

• Conditions: Metastatic Renal Cell Carcinoma; Brain Metastases
• Interventions: Drug: Cabozantinib; Device: Nivolumab; Radiation: Stereotactic Radiosurgery (SRS)

• Registration Number: NCT06132945
• Lead Sponsor: Memorial Sloan Kettering Cancer Center

Brief Summary

The purpose of this study is to find out whether the combination of cabozantinib, nivolumab, and radiation therapy is a safe and effective treatment that causes few or mild side effects in people with renal cell cancer that has spread to the brain. The researches will also look at how the study treatment affects the quality of life of participants. They will measure the quality of life by having participants complete questionnaires.
