NRG-GU012, Randomized Phase II Stereotactic Ablative Radiation Therapy (SABR) for Metastatic Unresected Renal Cell Carcinoma (RCC) Receiving Immunotherapy (SAMURAI)

NCT#NCT05327686

clinicaltrials.gov/show/NCTNCT05327686

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 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.

Male and Female – 18 years and older

• Pathologically (histologically or cytologically) proven diagnosis of renal cell carcinoma prior to registration
• Patients must have IMDC intermediate (1-2 factors) or poor risk disease (>= 3 factors)
• Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
• Node-positive unresectable (TxN1Mx) or metastatic (TxNxM1) based on the following diagnostic workup:
• 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 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
• Prior radiotherapy to the kidney that would result in overlap of radiation therapy fields treatment of the primary tumor
• Any systemic therapy for metastatic renal cell carcinoma (RCC) that was initiated >90 days before registration, note that prior chemotherapy for a different cancer is allowed (completed >3 years prior to registration)
