Brief Summary

This phase I trial studies the side effects and best doses of cabozantinib s-malate and nivolumab with or without ipilimumab in treating patients with genitourinary (genital and urinary organ) tumors that have spread to other places in the body (metastatic). Cabozantinib s-malate 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. It is not yet known whether giving cabozantinib s-malate and nivolumab alone or with ipilimumab works better in treating patients with genitourinary tumors.

Detailed Description


PRIMARY OBJECTIVES:

I. Determine the dose limiting toxicity (DLT) and recommended phase II dose (RP2D) of the
combination of cabozantinib s-malate (cabozantinib) and nivolumab (cabo-nivo) and separately
the combination of cabozantinib, nivolumab and ipilimumab (cabo-nivo-ipi) in patients with
genitourinary tumors. (Phase I) II. Assess safety and tolerability of cabozantinib, nivolumab
and ipilimumab (cabo-nivo-ipi) in patients with genitourinary tumors at this novel dose.
(Dose Level 8 Cohort)

SECONDARY OBJECTIVES:

I. Preliminarily evaluate the activity, as determined by objective response rate using
Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and the modified Immune-Related
Response Criteria (irRC), derived from RECIST1.1, of Ia. Cabo-nivo and cabo-nivo-ipi in
patients with advanced/refractory metastatic urothelial carcinoma (checkpoint inhibition
therapy naive) and with renal cell carcinoma in the second-line and beyond setting.

Ib. Cabo-nivo in patients with adenocarcinoma and with rare histologies (including squamous
or small cell carcinomas of the bladder, renal medullary carcinoma, sarcomatoid bladder and
renal cell carcinomas, plasmacytoid carcinoma of the bladder and others) in the first line or
beyond setting.

Ic. Cabo-nivo in patients with urothelial carcinoma previously treated with checkpoint
inhibition therapy in the second line or beyond setting.

Id. Cabo-nivo-ipi in patients with squamous cell carcinoma of the penis.

II. To evaluate the activity as determined by progression free survival (PFS) and overall
survival (OS) of:

IIa. Cabo-nivo and cabo-nivo-ipi in patients with advanced/refractory metastatic urothelial
carcinoma (checkpoint inhibition therapy naïve) or with renal cell carcinoma in the
second-line and beyond setting.

IIb. Cabo-nivo in patients with adenocarcinoma and with rare histologies (including squamous,
small cell carcinomas of the bladder, renal medullary carcinoma, sarcomatoid bladder and
renal cell carcinomas, plasmacytoid carcinoma of the bladder and others) in the first line or
beyond setting.

IIc. Cabo-nivo in patients with urothelial carcinoma previously treated with checkpoint
inhibition therapy in the second line or beyond setting.

IId. Cabo-nivo-ipi in patients with squamous cell carcinoma of the penis. III. To obtain
additional data to evaluate the safety of both combinations in patients with clear cell renal
cell carcinoma (ccRCC).

IV. To assess the number of malignant soft tissue and bone lesions on fludeoxyglucose F-18
(18F-FDG) positron emission tomography (PET)/computed tomography (CT) (scan 1) versus
combined fluorine F 18 sodium fluoride (18F-NaF) and 18F-FDG PET/CT (scan 2).

V. To assess response assessment by RECIST 1.1 using CT of the chest, abdomen, and pelvis
with intravenous (IV) contrast versus assessment by combined 18F-NaF and 18F-FDG PET/CT (scan
2) using number of malignant and change (modified PET RECIST [PERCIST]) of soft tissue and
bone lesions.

VI. To test the feasibility of automated density and volume application (ADaVA) as a means of
assessing tumor response.

VII. To assess PDL-1 and MET expression data and in exploratory fashion analyze their
association to response or clinical benefit.

EXPLORATORY OBJECTIVES:

I. To assess overall response rates (ORR) on patients who have been challenged or
re-challenged with ipilimumab therapy post disease progression.

II. To assess effects of treatment in patients with bone-only disease.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 treatment arms.

PART I: Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-28 and
nivolumab intravenously (IV) over 30 minutes on days 1 and 15. Cycles repeat every 28 days in
the absence of disease progression or unacceptable toxicity. After 22 cycles, patients
receive nivolumab IV over 30 minutes every 4 weeks in the absence of disease progression or
unacceptable toxicity. After progression, patients may receive cabozantinib s-malate PO,
nivolumab IV, and ipilimumab IV at the part II RP2D for 4 cycles followed by cabozantinib
s-malate PO QD and nivolumab IV every 2 weeks or 4 weeks if post-cycle 21 in the absence of
disease progression or unacceptable toxicity.

PART II: Patients receive cabozantinib s-malate PO QD on days 1-21, nivolumab IV over 30
minutes on day 1, and ipilimumab IV over 90 minutes on day 1. Treatment repeats every 21 days
for up to 4 cycles in the absence of disease progression or unacceptable toxicity. After
completion of 4 cycles with ipilimumab, patients continue receiving cabozantinib s-malate PO
QD on days 1-28 and nivolumab IV over 30 minutes on days 1 and 15. Treatment repeats every 28
days for up to 21 cycles in the absence of disease progression or unacceptable toxicity.
After 26 cycles, patients receive nivolumab IV over 30 minutes every 4 weeks in the absence
of disease progression or unacceptable toxicity. After progression, patients may receive
cabozantinib s-malate PO, nivolumab IV, and ipilimumab IV at the part II RP2D for 4 cycles
followed by cabozantinib s-malate PO QD and nivolumab IV every 2 weeks or 4 weeks if
post-cycle 21 in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 16 weeks, and then every 3
months thereafter.

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

- The effects of the drugs used in this trial on the developing human fetus are unknown;
however, cabozantinib was embryolethal in rats at exposures below the 140mg dose in
the label, with increased incidences of skeletal variations in rats and visceral
variations and malformations in rabbits; for this reason and because tyrosine kinase
inhibitors agents as well as other therapeutic agents used in this trial are known to
be teratogenic, women of child-bearing potential and men must agree to use adequate
contraception, as defined below, prior to study entry and for the duration of study
participation; should a woman become pregnant or suspect she is pregnant while she is
participating in this study, she should inform her treating physician immediately; men
treated or enrolled on this protocol must also agree to use adequate contraception
prior to the study, for the duration of study participation, and 7 months after
completion of all study medications; women treated or enrolled on this protocol must
also agree to use adequate contraception prior to the study, for the duration of study
participation, and for 5 months after completion of all study medications

- Sexually active subjects (men and women) must agree to use medically accepted barrier
methods of contraception (e.g., male or female condom) during the course of the study
and for 5 or 7 months for women or men respectively, after the last dose of study
drugs, even if oral contraceptives are also used; all subjects of reproductive
potential must agree to use both a barrier method and a second method of birth control
during the course of the study and for 5 or 7 months for women and men respectively
after the last dose of study drugs

- Tissue availability for programmed cell death ligand 1 (PD-L1) expression is mandatory
for enrollment; however if archived tissue is unavailable the patient will be given

be collected pretreatment (prior to the first dose of therapy) and post treatment
(after at least 1 dose, preferably 2 doses of nivolumab)

Because the lists of these agents are constantly changing, it is important to
regularly consult medical reference texts such as the Physicians' Desk Reference may
also provide this information; as part of the enrollment/informed consent procedures,
