Kidney Cancer Clinical Trial
Testing Cabozantinib With or Without Atezolizumab in Patients With Advanced Papillary Kidney Cancer, PAPMET2 Trial
This phase II trial compares the effect of atezolizumab in combination with usual treatment with cabozantinib to cabozantinib alone in patients with papillary renal cell carcinoma that has spread to other places in the body (metastatic). Papillary renal cell carcinoma (PRCC) is a type of kidney cancer that forms in the lining of the tiny tubes in the kidney that return filtered substances that the body needs back to the blood and remove extra fluid and waste as urine. Most papillary tumors look like long, thin finger-like growths under a microscope. It is also called papillary kidney cancer or PRCC. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply and may also prevent the growth of new blood vessels that tumors need to grow. By these actions it may help slow or stop the spread of cancer cells. Combination therapy with atezolizumab and cabozantinib may shrink the cancer and allow a longer survival time in patients with metastatic renal cell carcinoma.
I. To compare progression-free survival in participants with metastatic papillary renal cell carcinoma (mPRCC) randomized to cabozantinib S-malate (cabozantinib) with atezolizumab versus cabozantinib alone.
I. To compare overall survival in participants with mPRCC randomized to cabozantinib with atezolizumab versus cabozantinib alone.
II. To compare Response Evaluation Criteria in Solid Tumors (RECIST) objective response rate (confirmed and unconfirmed, complete and partial response) in participants with mPRCC randomized to cabozantinib with atezolizumab versus cabozantinib alone.
III. To evaluate the quantitative and qualitive adverse events observed in each treatment arm.
I. To bank biospecimens for future correlative studies.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive cabozantinib S-malate orally (PO) once daily (QD) on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) and bone scans throughout the trial. Patients may also undergo collection of blood samples throughout the trial.
ARM II: Patients receive cabozantinib S-malate PO QD on days 1-21 and atezolizumab intravenously (IV) over 30-60 minutes on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and bone scans throughout the trial. Patients may also undergo collection of blood samples throughout the trial.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for up to 5 years.
Participants must have a histologically confirmed diagnosis of metastatic papillary renal cell carcinoma (PRCC), either type 1 or type 2. (NOTE: A designation of type 1 or type 2 should be made by the local pathologist if possible but is not required). Mixed histologies which contain type 1 or type 2 along with any other RCC histology/histologies will be allowed provided that they contain a papillary component

The CT from a combined positron emission tomography (PET)/CT may be used to document only non-measurable disease unless it is of diagnostic quality. If there is clinical suspicion for bone metastases at the time of enrollment (at the discretion of the investigator), bone scan must be performed at baseline (within 42 days prior to registration)
