Is this trial a fit for you?

Likely a good fit

Adults (18+) with advanced or metastatic clear cell renal cell carcinoma (AJCC v8 Stage IV) with measurable disease and good performance status (ECOG 0-2).

Probably not a fit

Patients with non-measurable disease, prior extensive liver-directed therapies to target lesions, or disease in irradiated regions may not see benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a phase 2 interventional study evaluating the combination of VSV-IFNβ-NIS with the immune checkpoint inhibitors ipilimumab and nivolumab in adults with advanced or metastatic clear cell renal cell carcinoma. The approach uses a replication-competent virus engineered to target tumor cells and stimulate immune responses, alongside antibodies that boost anti-tumor immunity. Participants will undergo conventional cancer assessments and imaging, with procedures including biopsy, biospecimen collection, and routine imaging. Eligible patients have measurable disease, good performance status, and sufficient hemoglobin, and the study is conducted at Mayo Clinic in Rochester, MN.

Why it matters

Potential benefit: If successful, patients could experience tumor reduction or disease control from a potentially synergistic virus-based therapy combined with immunotherapy.

How similar studies have gone: Other studies combining oncolytic or virus-based therapy with immune checkpoint inhibitors have shown signals of activity, but this exact regimen is investigational for RCC.

* Measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

  * NOTE: Liver lesions that have been previously embolized (bland embolization, chemo- or radio-embolization) or have undergone percutaneous thermoablation are not eligible as target lesions. Tumor lesions in a previously irradiated area are not considered measurable disease; disease that is measurable by physical examination only is not eligible

* Total bilirubin ≤ 1.5 x upper limit of normal (ULN) (obtained ≤ 15 days prior to registration)
* Alanine aminotransferase (ALT) and aspartate transaminase (AST) ≤ 3 x ULN (≤ 5 x ULN for patients with liver involvement) (obtained ≤ 15 days prior to registration)
* Prothrombin time (PT)/international normalization ratio (INR)/activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN OR if patient is receiving anticoagulant therapy and INR or aPTT is within target range of therapy (≤ 5 x ULN for patients with liver involvement) (obtained ≤ 15 days prior to registration)
* Serum creatinine ≤ 1.5 x upper limit of normal (ULN) OR creatinine clearance ≥ 50 ml/min using the chronic kidney disease epidemiology (CKD-EPI) creatinine equation (per National Kidney Foundation) (obtained ≤ 15 days prior to registration)

  * NOTE: See calculator at National Kidney Foundation website here: https://www.kidney.org/professionals/kdoqi/gfr\_calculator
* Negative pregnancy test done ≤ 8 days prior to registration, for persons of childbearing potential only
* Provide written informed consent
* Willingness to provide mandatory blood specimens for correlative research
* Willingness to provide mandatory tissue specimens for correlative research
* Willing to return to Mayo Clinic for follow-up (during the active monitoring phase of the study)

Exclusion Criteria:

* Any of the following because this study involves an investigational agent, the genotoxic, mutagenic and teratogenic effects of which on the developing fetus and newborn are unknown:

  * Pregnant persons
  * Nursing persons
  * Persons of childbearing potential and persons able to father a child who are unwilling to employ adequate contraception
* Prior treatment for advanced or metastatic RCC \[American Joint Committee on Cancer (AJCC) Stage IV\]
* History of portal vein thrombosis involving more than intrahepatic portal vein branches: thrombosis of the right or left portal vein branch or the bifurcation, partial or complete obstruction of the portal vein trunk

  * NOTE: Level 0 or 1 tumor thrombus remain eligible; Level 2, 3, of 4 tumor thrombus related to the primary kidney tumor are ineligible
* Has received a live vaccine ≤ 30 days prior to registration

  * NOTE: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines and are NOT allowed

* New York Heart Association classification III or IV, known symptomatic coronary artery disease, or symptoms of coronary artery disease on systems review, or known cardiac arrhythmias \[atrial fibrillation or supraventricular tachycardia (SVT)\]
* Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
* Uncontrolled intercurrent illness including, but not limited to:

  * ongoing or active infection
  * symptomatic congestive heart failure
  * unstable angina pectoris
