Post menopause is defined as amenorrhea >= 12 consecutive months. Note: women
who have been amenorrheic for 12 or more months are still considered to be of
childbearing potential if the amenorrhea is possibly due to prior chemotherapy,
antiestrogens, ovarian suppression or any other reversible reason

- Pregnant women may not participate in this study because with cabozantinib,
nivolumab, and ipilimumab have potential for teratogenic or abortifacient effects.

secondary to treatment of the mother with cabozantinib, nivolumab, and ipilimumab,
breastfeeding should be discontinued if the mother is treated with these agents

brain metastases previously treated with whole brain radiation or radiosurgery who
are asymptomatic and do not require steroid treatment for at least 2 weeks before

regularly consult medical reference texts such as the Physicians' Desk
Reference may also provide this information. As part of the enrollment/informed

with other agents, and what to do if new medications need to be prescribed or

Detailed Description

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 OBJECTIVE: I. To assess effects of treatment in patients with bone-only disease by bone scan. OUTLINE: Patients receive cabozantinib orally (PO) once daily (QD) on days 1-21 of cycles 1-4 and on days 1-28 of subsequent cycles. Patients also receive nivolumab intravenously (IV) over 30 minutes on day 1 and ipilimumab IV over 90 minutes on day 1 of cycles 1-4. Patients then receive nivolumab IV over 30 minutes on day 1 of subsequent cycles. Treatment repeats every 21 days for cycles 1-4 and every 28 days for subsequent cycles for 2 years in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) or magnetic resonance imaging (MRI), and bone scan throughout the trial and may undergo positron emission tomography (PET)/CT throughout the trial. After completion of study treatment, patients are followed up every 2 months for up to 5 years.
