Brief Title
Testing the Combination of the Anti-cancer Drugs XL184 (Cabozantinib) and Nivolumab in Patients With Advanced Cancer and HIV
Official Title
Pilot Trial of Nivolumab Plus Cabozantinib for Advanced Solid Tumors in Patients With HIV Infection
Brief Summary
This phase I trial investigates the side effects of cabozantinib and nivolumab in treating
patients with cancer that may have spread from where it first started to nearby tissue, lymph
nodes, or distant parts of the body (advanced) and who are undergoing treatment for human
immunodeficiency virus (HIV). 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, 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 and nivolumab may shrink or
stabilize cancer in patients undergoing treatment for HIV.
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the safety of combined nivolumab and cabozantinib s-malate (XL184
[cabozantinib]) in human immunodeficiency virus (HIV) patients with advanced solid tumors.
II. To determine the feasibility to deliver the combined nivolumab and XL184 (cabozantinib)
for a minimum of 4 cycles in at least 75% of the subjects in the expanded cohort with Kaposi
sarcoma (KS) or to achieve a confirmed objective response.
SECONDARY OBJECTIVES:
I. To observe and record anti-tumor activity in subjects with Kaposi sarcoma (KS).
II. To assess the effect of treatment on participants' immune status (CD4 and CD8 cell
counts) and HIV viral loads.
III. To preliminarily evaluate the objective response rate (ORR) to the combination treatment
in subjects with KS.
EXPLORATORY OBJECTIVES:
I. To assess duration of response (DOR), progression-free survival (PFS), and overall
survival (OS) in subjects with KS.
II. To assess the PD-L1 immunohistochemistry (IHC) status in tumors and tumor
microenvironment and its association with clinical outcome.
III. To assess the expression characteristics and cellular distribution of immune checkpoints
(PD-L1, B7x, HHLA2, B7H3), infiltrating immune cells (CD4 T cells, CD8 T cells, regulatory
T-cells [Treg], myeloid-derived suppressor cell [MDSC]), and other tumor microenvironment
biomarkers (VEGF, VEGFR, MET, and AXL) in the tissue by multiplex quantitative
immunofluorescence (MQIF).
IV. To correlate markers of immune activation and expansion of immune cell subsets and
cytokines with clinical outcomes.
V. To assess the treatment effects on latent HIV reservoir. VI. To investigate the dynamic
changes of immune checkpoints, angiogenesis markers, and infiltrating immune cells among
subjects with available pre- and post-treatment biopsy samples (including subjects with
Kaposi sarcoma [KS]).
OUTLINE:
Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-28 of each cycle
and nivolumab intravenously (IV) over 30 minutes on day 1 of each cycle. Cycles repeat every
28 days for up to 1 year or 1 year after a partial response is achieved, or 6 months after a
complete response is achieved in the absence of disease progression or unacceptable toxicity.
Patients also undergo a computed tomography (CT) scan and/or magnetic resonance imaging (MRI)
as well as blood sample collection throughout the trial.
After completion of study treatment, patients are followed up for 16 weeks.

future pediatric trials
- For the six-patient safety cohort, subjects must have histologically or cytologically
confirmed advanced solid tumors that are metastatic or recurrent, and require
palliative systemic treatment, for which there are either Food and Drug Administration
(FDA) approved indications for XL184 (cabozantinib) or nivolumab or have at least
phase 2 data clearly indicating activity (such as renal cell carcinoma [RCC],
hepatocellular carcinoma [HCC], medullary thyroid carcinoma [MTC], melanoma, non-small
cell lung cancer [NSCLC], head and neck cancer, urothelial carcinoma, small cell lung
cancer [SCLC], radioiodine-refractory differentiated thyroid cancer, ovarian cancer,
castration-resistant prostate carcinoma [CRPC], and triple-negative breast cancer
[TNBC]). Subjects must have progressed, or are intolerant, or decline systemic therapy
associated with clinically significant survival benefit if checkpoint blockade is not
an approved or accepted treatment. The expansion cohort is limited to subjects with
KS. Histologic, cytologic, and pathologic confirmation of KS is required
- Any number of prior cancer therapies will be permitted, including treatment naive
subjects. (Note: For KS, treatment naive asymptomatic subjects will be permitted. But
treatment naive KS subjects with visceral symptomatic disease or complicated KS HHV 8
disease including Castleman's disease will be excluded and should receive front-line
standard of care)

- Platelets >= 75,000/mcL
- Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (If, however, the
participant has Gilbert's disease or unconjugated hyperbilirubinemia that is
considered to be secondary to antiretroviral therapy, then the total bilirubin must be
=< 3 x ULN)
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase
[SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT])

infection at any time prior to study entry, as evidenced by positive enzyme-linked
immunosorbent assay (ELISA), positive Western blot, or any other federally approved
licensed HIV test. Alternatively, this documentation may include a record that another
physician has documented that the participant has HIV infection based on prior ELISA
and Western blot, or other approved diagnostic tests. Subjects must receive
appropriate care and treatment for HIV infection. An eligible patient should be on
anti-retroviral therapy (ART) that is not strongly CYP3A4 inhibiting or otherwise
prohibited by the protocol (e.g. drug-drug interactions) or the patient must be
converted to one of these regimens before starting investigational therapy in order to
avoid dose modulation of cabozantinib
- Life expectancy of >= 12 weeks
- For subjects with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral
load must be undetectable on suppressive therapy, if indicated
- Subjects with a history of hepatitis C virus (HCV) infection must have been treated
and cured including self-cured cases. For subjects with HCV infection who are
currently on treatment, they are eligible if they have an undetectable HCV viral load
- Subjects with a prior or concurrent malignancy whose natural history or treatment does
not have the potential to interfere with the safety or efficacy assessment of the
investigational regimen are eligible for this trial
- The effects of nivolumab and XL184 (cabozantinib) on the developing human fetus are
unknown. For this reason, women of child-bearing potential (WOCBP) and men must agree
to use adequate contraception (hormonal or barrier method of birth control;
abstinence) prior to study entry and for the duration of study participation. WOCBP
should use an adequate method to avoid pregnancy for 5 months after the last dose of
investigational drug. WOCBP must have a negative serum or urine pregnancy test within
72 hours prior to the start of receiving the first dose of the study medication. Men
who are sexually active with WOCBP must use any contraceptive method with a failure
rate of less than 1% per year. Men receiving nivolumab and who are sexually active
with WOCBP will be instructed to adhere to contraception for a period of 7 months
after the last dose of investigational product. Women who are not of childbearing
potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic
men) do not require contraception
- Women of childbearing potential (WOCBP) is defined as any female who has
experienced menarche and who has not undergone surgical sterilization
(hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause
is defined clinically as 12 months of amenorrhea in a woman over 45 in the
absence of other biological or physiological causes. In addition, women under the
age of 55 must have a documented serum follicle stimulating hormone (FSH) level
less than 40 mIU/mL

obstruction and abdominal carcinomatosis which are known risk factors for
bowel perforation should be evaluated for the potential need for additional
treatment before coming on study
- Any of following within 6 months before the first dose of study treatment:
- Abdominal fistula
- Gastrointestinal perforation
- Bowel obstruction or gastric outlet obstruction intra-abdominal abscess.
Note: Complete resolution of an intra-abdominal abscess must be confirmed
prior to initiating treatment with cabozantinib even if the abscess occurred
more than 6 months before
- Other disorders associated with a high risk of fistula formation including
percutaneous endoscopic gastrostomy (PEG) tube placement within 3 months before
the first dose of study therapy
- Subjects with active autoimmune disease or history of autoimmune disease that might
recur, which may affect vital organ function or require immune suppressive treatment
including systemic corticosteroids, should be excluded. These include but are not
limited to subjects with a history of immune related neurologic disease, multiple
sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia
gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE),
connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's,
ulcerative colitis, hepatitis; and subjects with a history of toxic epidermal
necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be
excluded because of the risk of recurrence or exacerbation of disease. Subjects with
vitiligo, endocrine deficiencies including thyroiditis managed with replacement
hormones including physiologic corticosteroids are eligible. Subjects with rheumatoid
arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with
topical medication and subjects with positive serology, such as antinuclear antibodies
(ANA), anti-thyroid antibodies should be evaluated for the presence of target organ
involvement and potential need for systemic treatment but should otherwise be
eligible. Subjects are permitted to enroll if they have vitiligo, type I diabetes
mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone
replacement, psoriasis not requiring systemic treatment, or conditions not expected to
recur in the absence of an external trigger (precipitating event)
- Major surgery (e.g., laparoscopic nephrectomy, GI surgery, removal or biopsy of brain
metastasis) within 2 weeks before first dose of study treatment. Minor surgeries
within 10 days before first dose of study treatment. Subjects must have complete wound
healing from major surgery or minor surgery before first dose of study treatment.
Subjects with clinically relevant ongoing complications from prior surgery are not
eligible
- The subject is unable to swallow tablets
- History of organ transplant or stem cell transplant
- Subjects with uncontrolled intercurrent illness
- Subjects with psychiatric illness/social situations that would limit compliance with
study requirements
- Pregnant women are excluded from this study because XL184 (cabozantinib) has the
potential for teratogenic or abortifacient effects, and the effects of nivolumab on
the developing fetus are not well known. Because there is an unknown but potential
risk for AEs in nursing infants secondary to treatment of the mother, breastfeeding
must be discontinued if the mother is treated with XL184 (cabozantinib) or nivolumab
