| Eligibility |
Inclusion Criteria:
- Must give written informed consent prior to initiation of therapy, in keeping with the
policies of the institution. Patients with a history of major psychiatric illness must
be judged able to fully understand the investigational nature of the study and the
risks associated with the therapy
- Must have histologically confirmed HCC (documentation of original biopsy for diagnosis
is acceptable if tumor tissue is unavailable) or clinical diagnosis by AASLD (American
Association for the Study for Liver Diseases) criteria in cirrhotic subjects (presence
of non-rim arterial phase hyperenhancement relative to the liver parenchyma with
venous washout for tumors >= 1 cm). For subjects without cirrhosis, histological
confirmation is mandatory. The determination of cirrhosis status will ultimately lie
in the clinical judgment of the surgical oncologist and medical oncologist involved in
the care of the patient
- Must be eligible for liver resection with curative intent; diagnosis must be confirmed
by pathologist review of screening biopsy and the determination of resectability
status will ultimately lie in the clinical judgment of the surgical oncologist and
medical oncologist involved in the care of the patient
- Must have measurable disease defined as a lesion that can be accurately measured in at
least one dimension (longest diameter to be recorded) and measures >= 15 mm with
conventional techniques or >= 10 mm with more sensitive techniques such as magnetic
resonance imaging (MRI) or spiral computed tomography (CT) scan
- Allowed are prior treatments for HCC including prior surgery, radiation therapy,
local-regional therapy (ablation or arterial directed therapies), or systemic therapy
including sorafenib or chemotherapy. (Prior anti-PD-1 or ADI-PEG 20 therapies are not
allowed)

alanine transaminase (ALT) ) (serum glutamate pyruvate transaminase [SGPT]) =< 5 x
institutional ULN (within 14 days of the first dose of study drug)
- Serum uric acid =< 10 mg/dL (595 umol/L) (with or without medication control) (within
14 days of the first dose of study drug)
- Must be >= 18 years of age
- Must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or
equivalent units of human chorionic gonadotropin [HCG]) within 24 hours prior to the
start of study drug and every 4 weeks while taking nivolumab (for women of
childbearing potential [WOCBP])
- Must not be breastfeeding
- Must agree (WOCBP) to follow instructions for method(s) of contraception from the time
of enrollment for the duration of treatment with study drug (s) for a total of 12
months post treatment completion. Men who are sexually active with WOCBP must agree to
follow instructions for method(s) of contraception for the duration of treatment with
study drug(s) plus 5 half-lives of study drug (s) plus 90 days (duration of sperm
turnover) for a total of 7 months post-treatment completion
- NOTE: Azoospermic males and WOCBP who are continuously not heterosexually active
are exempt from contraceptive requirements. However, WOCBP must still undergo
pregnancy testing as described in these sections. Investigators shall counsel
WOCBP and male subjects who are sexually active with WOCBP on the importance of
pregnancy prevention and the implications of an unexpected pregnancy
Investigators shall advise WOCBP and male subjects who are sexually active with
WOCBP on the use of highly effective methods of contraception. Highly effective
methods of contraception have a failure rate of < 1% per year when used
consistently and correctly. At a minimum, subjects must agree to the use of two
methods of contraception, with one method being highly effective and the other
method being either highly effective or less effective as listed below:
HIGHLY EFFECTIVE METHODS OF CONTRACEPTION
- Male condoms with spermicide
- Hormonal methods of contraception including combined oral contraceptive pills, vaginal
ring, injectables, implants, and intrauterine devices (IUDs) such as Mirena by WOCBP
subject or male subject's WOCBP partner.
- Nonhormonal IUDs, such as ParaGard
- Tubal ligation
- Vasectomy
- Complete Abstinence*
- Complete abstinence is defined as complete avoidance of heterosexual intercourse and
is an acceptable form of contraception for all study drugs. Abstinence is only
acceptable when this is in line with the preferred and usual lifestyle of the subject.
Periodic abstinence (eg, calendar, ovulation, symptothermal, profession of abstinence
for entry into a clinical trial, post-ovulation methods) and withdrawal are not
acceptable methods of contraception. Subjects who choose complete abstinence are not
required to use a second method of contraception, but female subjects must continue to
have pregnancy tests. Acceptable alternate methods of highly effective contraception
must be discussed in the event that the subject chooses to forego complete abstinence.
LESS EFFECTIVE METHODS OF CONTRACEPTION
- Diaphragm with spermicide
- Cervical cap with spermicide
- Vaginal sponge
- Male condom without spermicide*
- Progestin only pills by WOCBP subject or male subject's WOCBP partner
- Female condom*
- A male and female condom must not be used together
- Must not have received prior anticancer therapy with ADI-PEG 20 or anti-PD1 for
HCC. Must not be receiving any concomitant systemic therapy for HCC

tachycardia are eligible); significant vascular disease or symptomatic peripheral
vascular disease
- Has a history of other diseases, metabolic dysfunction, physical examination finding,
