Testing Cabozantinib With or Without Atezolizumab in Patients With Advanced Papillary Kidney Cancer, PAPMET2 Trial

United States200 participantsStarted 2023-03-24

Plain-language summary

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 from where it first started (primary site) 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 the body's immune system attack the tumor 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 tumor 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 tumor cells. Combination therapy with atezolizumab and cabozantinib may shrink the tumor and allow a longer survival time in patients with metastatic renal cell carcinoma.

Inclusion Criteria: * 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 * Participants must have measurable disease per RECIST 1.1 criteria. All measurable lesions must be assessed by CT or MRI within 28 days prior to registration. All non-measurable lesions must be assessed by CT or MRI, or nuclear medicine bone scan within 42 days prior to registration. 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) * Participants with new or progressive brain metastases (active brain metastases) must not require immediate central nervous system (CNS) specific treatment at the time of study registration or anticipated during the first cycle of therapy. Patients with leptomeningeal disease are excluded from enrolling * Participants with measurable disease, per RECIST version (v)1.1, must be present outside the CNS * Participants must have n…
