Phase II Randomized Study of High Dose Interleukin-2 Versus Stereotactic Body Radiation (SBRT) and High Dose Interleukin-2 (IL-2) in Patients With Metastatic Renal Cancer
All patients will receive IL-2 (14 planned doses with an additional cycle 14 days after the first). Responding patients with regressing disease are eligible for up to 6 IL-2 cycles. Patients assigned to SBRT arm will receive two doses of SBRT on the Wednesday and Friday before the Monday on which IL-2 starts.
• Histological confirmation of predominant conventional (clear cell) renal cancer
• Patients must be ≥ 18 years of age
• Tumors amenable to SBRT in lungs (central locations preferred), mediastinum, chest wall, bones with a soft tissue component (other than long bones), or liver, liver hilum and associated lymph nodes (inclusive of immediately adjacent masses), 1 - 3 foci; no minimum size, but none greater than 7 cm. Patients may have other metastases but only a maximum of 3 will be treated
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
• Women of childbearing potential must have a negative serum or urine pregnancy test within 72 hours prior to the start of protocol treatment. In addition, women of childbearing potential as well as male patients must agree to take appropriate precautions to avoid pregnancy
• Patients must agree to participate in the Prometheus IL-2 patient registry (PROCLAIM registry)
• Patients must sign a study-specific consent form
