About this trial

This phase II trial tests whether the addition of radiation to the primary tumor, typically given with stereotactic ablative radiation therapy (SABR), in combination with standard of care immunotherapy improves outcomes in patients with renal cell cancer that is not recommended for surgery and has spread from where it first started (primary site) to other places in the body (metastatic). Radiation therapy uses high energy photons to kill tumor cells and shrink tumors. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses of radiation over a shorter period and cause less damage to normal tissue. Immunotherapy with monoclonal antibodies, such as nivolumab, ipilimumab, avelumab, and pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Axitinib, cabozantinib, and lenvatinib are in a class of medications called antiangiogenic agents. They work by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Giving SABR in combination with standard of care immunotherapy may help shrink or stabilize the cancer in patients with renal cell cancer.

Eligibility criteria

Qualifiers

Pathologically (histologically or cytologically) proven diagnosis of renal cell carcinoma prior to registration

History/physical examination within 45 days prior to registration

CT/magnetic resonance imaging (MRI) of the chest/abdomen/pelvis within 45 days prior to registration

Patients must have IMDC intermediate (1-2 factors) or poor risk disease (>= 3 factors)

Disqualifiers

Patients with planned treatment of all metastatic disease with definitive therapy including either surgery, ablative (non-palliative) doses of radiation, or intervention of some type (definitive interventional radiology techniques) to ALL metastatic sites rendering the patient without extra-renal measurable disease. Patients NOT planned for definitive treatment of all metastatic sites are eligible. Lesions radiated palliatively are not eligible for response assessment

Patients with untreated or unstable brain metastases or cranial epidural disease

Note: Patients who have been adequately treated with radiotherapy, radiosurgery, or surgery and stable for at least 4 weeks prior to registration as documented by MRI or CT imaging or deemed stable by clinical investigator are eligible. Treated brain metastases are defined as having no ongoing requirement for steroids and no evidence of progression or hemorrhage after treatment for at least 4 weeks prior to registration as documented by MRI or CT imaging or deemed stable by clinical investigator

Prior radiotherapy to the kidney that would result in overlap of radiation therapy fields treatment of the primary tumor
