Phase III Randomized Trial of Stereotactic Ablative Radiotherapy (SAbR) for Oligometastatic Advanced Renal Carcinoma (SOAR)
This phase III trial compares the effect of stero-ablative radiotherapy (SAbR) followed by standard of care systemic therapy, to standard of care systemic therapy alone, in patients with kidney cancer that has spread from where it first started (primary site) to a limited (2-5) number of places in the body (metastatic). Study doctors want to find out if this approach is better or worse than the usual approach for metastatic kidney cancer. The usual approach is defined as the care most people get for metastatic kidney cancer which includes systemic therapy such as immunotherapy (given through the veins) and/or small molecular inhibitor (tablets taken by mouth). Radiotherapy uses high energy x-rays to kill cancer cells and shrink tumors. SAbR uses special equipment to position a patient and deliver radiation to tumors with high precision. Giving SAbR prior to systemic therapy may kill more tumor cells than the usual approach, which is systemic therapy alone.
• Patient must be \>= 18 years of age
• Patient must have a pathologically (histologically or cytologically) proven diagnosis of renal cell carcinoma (RCC) prior to randomization
• Patient may have any RCC histology except a histology that has a sarcomatoid component
• Patient must have primary site addressed by local therapy. If the primary RCC is intact, the patient must undergo local treatment to the primary before randomization
• Patient must have favorable or intermediate International Metastatic RCC Database Consortium (IMDC) risk (0-2) at the time of randomization
• Patient must have a total of between 2 and 5 metastatic lesions, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria with imaging obtained within 45 days prior to randomization
• Patient must have a documentation from a radiation oncologist confirming that all sites are amenable to SAbR
• Patient may have received prior therapy in the adjuvant setting as long as potential trial participants have recovered from clinically significant adverse events of their most recent therapy/intervention prior to enrollment
• 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
• Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
• All patients of childbearing potential must have a blood test or urine study within 14 days prior to randomization to rule out pregnancy
⁃ A patient of childbearing potential is defined as anyone, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:
∙ Has achieved menarche at some point
‣ Has not undergone a hysterectomy or bilateral oophorectomy
‣ Has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
• Patient must have the ability to understand and the willingness to sign a written informed consent document. Patients with impaired decision-making capacity (IDMC) who have a legally authorized representative (LAR) or caregiver and/or family member available will also be considered eligible
• Patient must have a Eastern Cooperative Oncology Group (ECOG) Performance Status 0-2
• Patients must have adequate organ and bone marrow function as per the recommended guidelines and the respective Food and Drug Administration \[FDA\] package insert required for the systemic therapy chosen by the treating oncologist. We recognize that patients may have varying levels of renal and liver function that will impact which systemic therapy is appropriate for the patient. We do not require all patients to have specific baseline laboratory thresholds but do ask the treating oncologist to attest that the patient has adequate organ and bone marrow function to safely receive one of the first line systemic therapies listed in the protocol as a standard of care treatment option
• Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of randomization are eligible for this trial. Testing for HIV is not required for entry onto the study
• For patients with history of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated. If no previous history, testing for HBV is not required for entry onto the study
• Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load. If no previous history, testing for HCV is not required for entry onto the study
• In order to participate in the QOL portion of the protocol, the patient must speak one of the languages in which the NFKSI-19 and EQ-5D-5L is available
⁃ NOTE: Sites cannot translate the associated QOL forms
