Nivolumab and Yttrium Y 90 Glass Microspheres in Treating Patients With Advanced Liver Cancer

PRIMARY OBJECTIVES:

I. To identify MTD of nivolumab for combination treatment of nivolumab and Y-90 in this
population.

SECONDARY OBJECTIVES:

I. To evaluate the proportion of patients with objective response rate (ORR) (according to
Response Evaluation Criteria in Solid Tumors [RECIST] criteria) to the combination treatment
of nivolumab with Y-90.

II. To evaluate the proportion of patients alive and progression free at 24 weeks in the
described population.

III. To evaluate the toxicities (according to the National Comprehensive Cancer Network
[NCCN] Common Terminology Criteria for Adverse Events [CTCAE] version (v)4.03) and
tolerability of nivolumab and Y-90 in patients with advanced hepatocellular carcinoma IV. To
determine the disease control rate (DCR) to the combination of nivolumab and Y-90 at 24
months from the start of nivolumab treatment.

TERTIARY OBJECTIVES:

I. Programmed cell death 1 ligand 1 (PD-L1) protein on tumor cells and the expression levels
of other markers of inflammatory/immune signature that may include but not be limited to
programmed cell death protein 1 (PD-1), tumor necrosis factor receptor superfamily, member 4
(OX40), cluster of differentiation (CD) 73, CD39, T cell immunoglobulin and T-cell
immunoglobulin and mucin-domain containing-3 (TIM3), glucocorticoid-induced tumour necrosis
factor receptor (GITRL), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), CD3, CD4, CD8,
CD45RO, forkhead box P3 (FOXP3), and granzyme by immunohistochemistry (IHC) and/or flow
cytometry will be evaluated.

II. Whole exome sequencing and computational analyses will be performed to assess mutanome
and immunome (subpopulations of immune cells).

III. Change in clonal burden landscape of various mutanome and immunome will be analyzed to
investigate its correlation with treatment response or development of resistance to
treatment.

OUTLINE: This is a phase I, dose-escalation study of nivolumab followed by a phase Ib study.

Patients receive yttrium Y 90 glass microspheres intraarterially (IA). Approximately 4 weeks
after yttrium Y 90 glass microspheres treatment, nivolumab will be administered intravenously
(IV) over approximately 60 minutes every 2 weeks until disease progression, unacceptable
toxicity, or withdrawal of consent.

After completion of study treatment, patients are followed up 30 days after the last dose of
nivolumab and again at 100 days after discontinuing study drug.

Inclusion Criteria:

- Patients must have a diagnosis of hepatocellular carcinoma (HCC) confirmed by American
Association for Study of Liver Diseases (AASLD) guidelines with a Childs-Pugh score of
A or B (but, =< Childs score B8)

- NOTE: If the patient does not have histological confirmation of disease by
biopsy, diagnosis of HCC must be documented with approval by a tumor board or
other multidisciplinary conference

- Patients must have at least 1 lesion that is measurable using RECIST guidelines.

NOTE: A previously irradiated lesion can be considered a target lesion if the lesion is
well defined, measurable per RECIST, and has clearly progressed.

NOTE: For patients with infiltrative disease, evaluable disease needs to be confirmed by
pathology if RECIST measurements cannot be made.

- Patients must have advanced disease that is not amenable to transplant or resection

- Patients may be treatment naive or have received any number of prior therapies

- NOTE: Prior immunotherapy is contraindicated and not permitted

- Patients with chronic hepatitis B are eligible as long as they have evidence of
ongoing viral replication (detectable hepatitis B surface antigen [HBsAg], hepatitis B
envelope antigen [HBeAg], or hepatitis B virus [HBV] deoxyribonucleic acid [DNA]);
they must have HBV DNA viral load < 100 IU/mL at screening; in addition, they must be
on antiviral therapy per regional standard of care guidelines prior to initiation of
study therapy; if not on antiviral therapy at screening, then the subject must
initiate treatment per regional standard of care guidelines at the time of consent;
both HBeAg positive and negative patients will be included
