This phase II trial studies how well cabozantinib works in combination with nivolumab and ipilimumab in treating patients with rare genitourinary (GU) tumors that that has spread from where it first started (primary site) to other places in the body. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib, nivolumab, and ipilimumab may work better in treating patients with genitourinary tumors that have no treatment options compared to giving cabozantinib, nivolumab, or ipilimumab alone.

PRIMARY OBJECTIVE:

I. To evaluate the efficacy of cabozantinib s-malate (cabozantinib) combined with nivolumab and ipilimumab in the first or second-line (and beyond) setting for patients within each of the rare genitourinary (GU) variant histology group of interest, as measured by objective response rate (ORR).

SECONDARY OBJECTIVES:

I. To estimate the progression-free survival (PFS) for patients treated with cabozantinib combined with nivolumab and ipilimumab within each rare variant histology.

II. To estimate the overall survival (OS) for patients treated with cabozantinib combined with nivolumab and ipilimumab within each rare variant histology.

III. To estimate the clinical benefit rate (defined as complete response \[CR\] or partial response \[PR\] or stable disease \[SD\]) for patients treated with cabozantinib combined with nivolumab and ipilimumab within each rare variant histology.

IV. To assess the safety of treating patients with rare variant histologies with cabozantinib combined with nivolumab and ipilimumab.

V. To support tissue banking and collection of clinical follow-up data for GU tract rare histological variants.

EXPLORATORY OBJECTIVES:

I. To assess effects of treatment in patients with bone-only disease by bone scan.

OUTLINE:

Patients receive cabozantinib orally (PO), nivolumab intravenously (IV) and ipilimumab IV while on study. Patients undergo computed tomography (CT) scan, magnetic resonance imaging (MRI), positron emission tomography (PET) and bone scans throughout the study.

Testing the Effectiveness of Two Immunotherapy Drugs (Nivolumab and Ipilimumab) With One Anti-cancer Targeted Drug (Cabozantinib) for Rare Genitourinary Tumors

A Phase II Study of Ipilimumab, Cabozantinib, and Nivolumab in Rare Genitourinary Cancers (ICONIC)

NCI is committed to sharing data in accordance with NIH policy. For more details on how clinical trial data is shared, access the link to the NIH data sharing policy page

The bone-only tumor patients will be evaluated in an exploratory fashion (if no RECIST measurements are available). A maximum of 15 patients with bone-only disease will be enrolled and evaluated using PFS for a descriptive analysis of the effect of treatment.

An objective response is defined as a confirmed complete response (CR) or partial response (PR) as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. A confirmed tumor response is defined to be either a CR or PR noted as the objective status on 2 consecutive evaluations at least 4 weeks apart. Will be estimated by the number of confirmed objective responses divided by the total number of evaluable patients. Confidence intervals for the true ORR will be calculated.

Defined for all evaluable patients who have achieved an objective response as the date at which the patient's earliest best objective status is first noted to be either a CR or PR to the earliest date progression is documented.

The median its 95% confidence interval will be determined and will be summarized using the Kaplan-Meier estimator.

A confirmed clinical benefit is defined to be either a CR or PR noted as the objective status on 2 consecutive evaluations at least 4 weeks apart or a confirmed stable disease at two consecutive tumor assessments at least 3 months apart. The CBR will be estimated by the number of patients with confirmed clinical benefit divided by the total number of evaluable patients. Confidence intervals for the true CBR will be calculated using exact binomial confidence intervals.

Will be assessed using Common Terminology Criteria for Adverse Events version 5.0. The maximum of a particular AE will be determined for each patient. Tables will summarize the number and relative frequency of patients observing an AE as well as the number and relative frequency of patients experiencing any AE of grade 3 or greater.
