Cabozantinib S-Malate, Crizotinib, Savolitinib, or Sunitinib Malate in Treating Patients With Locally Advanced or Metastatic Kidney Cancer

PRIMARY OBJECTIVES:

I. To compare progression-free survival (PFS) in patients with metastatic papillary renal
cell carcinoma (mPRCC) treated with sunitinib malate (sunitinib) to PFS in patients with
mPRCC treated with MET kinase inhibitors.

SECONDARY OBJECTIVES:

I. To compare Response Evaluation Criteria in Solid Tumors (RECIST) response rate (RR;
defined as the combined rate of confirmed and unconfirmed partial response [PR] and complete
response [CR]) in patients with mPRCC treated with sunitinib to RR in patients treated with
putative MET inhibitors.

II. To compare overall survival (OS) in patients with mPRCC treated with sunitinib to OS in
patients with mPRCC treated with putative MET inhibitors.

III. To compare the safety profile of sunitinib and putative MET inhibitors in patients with
mPRCC.

TRANSLATIONAL OBJECTIVES:

I. To evaluate the prognostic and predictive value of MET mutations, MET copy number or other
markers of MET signaling in patients with mPRCC treated with putative MET inhibitors.

OUTLINE: Patients are randomized to 1 of 4 treatment arms. As of 12/5/18, patients will only
be randomized to Arm I or Arm II.

ARM I: Patients receive sunitinib malate orally (PO) on days 1-28.

ARM II: Patients receive cabozantinib s-malate PO on days 1-42.

ARM III (CLOSED TO ACCRUAL 12/5/18): Patients receive crizotinib PO twice daily (BID) on days
1-42.

ARM IV (CLOSED TO ACCRUAL 12/5/18): Patients receive savolitinib PO on days 1-42.

In all arms, courses repeat every 42 days in the absence of disease progression or
unacceptable toxicity.

After completion of study treatment, patients are followed up for 3 years.

Inclusion Criteria:

- Patients must have histologically or cytologically confirmed papillary histology renal
cell carcinoma which is metastatic or locally advanced disease not amenable to
surgical resection; (NOTE: a designation of type I or type II should be made by the
local pathologist if possible); mixed histologies containing type I or type II will be
allowed provided that they contain >= 50% of the papillary component

- Patients must also have measurable disease, defined as at least one lesion that can be
accurately measured in at least one dimension; disease X-rays, scans or physical
examinations used for tumor measurement must have been completed within 28 days prior
to registration; if there is clinical suspicion for bone metastases at the time of
enrollment (at the discretion of the investigator), bone scan should be performed at
baseline (within 42 days prior to registration); all disease must be assessed and
documented on the Baseline Tumor Assessment form

- Patients with a history of treated brain metastases who are asymptomatic and have not
received steroid therapy in the 14 days prior to registration are eligible;
anti-seizure medications are allowed provided they are non-enzyme inducing (e.g.
topiramate, levetiracetam, gabapentin)

- Patients may have received up to one prior systemic therapy for advanced or metastatic
renal cell carcinoma with the exception of another VEGF inhibitor Food and Drug
Administration (FDA)-approved for advanced RCC (i.e., pazopanib, bevacizumab,
sorafenib or axitinib); if a patient develops metastatic disease within six months of
discontinuation of adjuvant therapy, this will constitute one prior systemic therapy
for advanced or metastatic renal cell carcinoma (RCC); if a patient develops
metastatic disease and more than six months has elapsed since discontinuation of
adjuvant therapy, this will not constitute prior systemic therapy for advanced or
metastatic RCC; patients may have also received prior immunotherapy; patients must not

CYP3A4 inhibitors (e.g. boceprevir, cobicistat, danoprevir, elvitegravir/RIT,
fluvoxamine, indinavir, itraconazole, ketoconazole, lopinavir/RIT, nefazodone,
nelfinavir, posaconazole, ritonavir, telaprevir, telithromycin, tipravavir/RIT, or
voriconazole); strong CYP3A4 inducers (e.g. avasimibe, phenytoin, rifampin,
rifabutin); potent inhibitors of CYP1A2 (e.g. ciprofloxacin); and/or drugs known to be
CYP3A4 substrates with a narrow therapeutic range (e.g., diergotamine, ergotamine)

registration must demonstrate an ejection fraction (EF) >= 50%; patients must have
corrected QT (QTc) interval < 500 msec on prestudy electrocardiogram (EKG) and no
known history of congenital long QT syndrome; patients must not have experienced
unstable angina pectoris, clinically significant cardiac arrhythmias, or stroke
(transient ischemic attack [TIA] or other ischemic event) within 3 months prior to
registration and not have experienced myocardial infarction or thromboembolic event

must not have gastrointestinal tract disease resulting in an inability to take oral
medication or a requirement for intravenous (IV) alimentation, prior surgical
procedures that could in the opinion of the treating investigator affect absorption,
or active peptic ulcer disease; patients with intractable nausea or vomiting are not
eligible

- Patients must not have had any clinically-significant GI bleeding within 6 months
prior to registration and patients must not have a GI disorder which (at the
discretion of the investigator) bears a high risk of perforation or fistula; examples
of this include (but are not limited to) Crohn's disease or tumor with transmural
extension through the gastrointestinal lining

- Patients must not have had hemoptysis of >= 0.5 teaspoon (2.5 ml) of red blood within
3 months prior registration

- Patients must not demonstrate any other signs indicative of pulmonary hemorrhage
within 3 months prior to registration

phosphorus, and total protein must be assessed within 28 days of registration

- No other prior malignancy is allowed except for the following: adequately treated
basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated
stage I or II cancer from which the patient is currently in complete remission, or any
other cancer from which the patient has been disease free for 3 years; men receiving
active surveillance for prostate cancer may also be enrolled

- Due to the unknown effects of the study drugs, patients must not be pregnant or
nursing; women/men of reproductive potential must have agreed to use an effective
contraceptive method while receiving study drug and for three months after last dose
of study drug; a woman is considered to be of "reproductive potential" if she has had
menses at any time in the preceding 12 consecutive months; in addition to routine
contraceptive methods, "effective contraception" also includes heterosexual celibacy
and surgery intended to prevent pregnancy (or with a side-effect of pregnancy
prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal
ligation; however, if at any point a previously celibate patient chooses to become
heterosexually active during the time period for use of contraceptive measures
outlined in the protocol, he/she is responsible for beginning contraceptive measures

- Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral
therapy are ineligible because of the potential for pharmacokinetic interactions with
cabozantinib, crizotinib, savolitinib or sunitinib; in addition these patients are at
increased risk of lethal infections when treated with marrow suppressive therapy;
appropriate studies will be undertaken in patients receiving combination
antiretroviral therapy when indicated

- Patients must have tissue available and be willing to submit for independent
pathologic review in order to classify type I versus type II papillary disease

- Patients must be offered the opportunity to participate in specimen banking for future
translational medicine studies

- Patients must be informed of the investigational nature of this study and must sign
and give written informed consent in accordance with institutional and federal
guidelines

- As a part of the OPEN registration process the treating institution's identity is
provided in order to ensure that the current (within 365 days) date of institutional
review board approval for this study has been entered in the system.
