Nivolumab and Yttrium-90 in Treating Patients With Liver Cancer Undergoing Surgical Resection

PRIMARY OBJECTIVES:

I. To assess the hepatocellular carcinoma (HCC) recurrence rate post-resection in patients
intended to undergo resection post yttrium Y 90 glass microspheres (yttrium-90 [Y-90]) +
nivolumab.

SECONDARY OBJECTIVES:

I. To investigate the safety and feasibility of radioembolization and nivolumab in patients
with HCC with intent for resection.

II. To assess the pattern of recurrence post-resection (time frame and location of
recurrence).

III. To evaluate efficacy in patients with HCC treated with Y90 + nivolumab using overall
survival.

IV. To evaluate the drop-out rate and incremental changes in future liver remnant (FLR).

EXPLORATORY OBJECTIVES:

I. To assess immune-related biomarkers from original tumor biopsy if available. II. To
identify differences in immunological profiles among patients who go undergo resection versus
those who do not undergo resection due to progression or failure to grow FLR to sufficient
level. III. In patients with hepatitis C virus (HCV), will explore changes in immunological
profile associated with direct acting anti-viral agents.

OUTLINE:

Patients receive standard of care yttrium Y 90 glass microspheres intravenously (IV). Within
1-2 weeks of completing of yttrium-90 treatment, patients receive nivolumab IV over 30
minutes on day 1. Treatment repeats every 2 weeks for up to 4 doses in the absence of disease
progression or unacceptable toxicity. If imaging shows adequate FLR and at least stable
disease, patients will undergo resection within 2 weeks after the last dose of nivolumab.
Patients who do not complete resection due to feasibility and have progressed or have
evidence of high-risk explant may continue to receive nivolumab IV every 2 weeks for up to 1
year.

After completion of study treatment, patients are followed up at 30 days and then
periodically for up to 3 years.

mg/dL
