| Eligibility |
Inclusion Criteria:
- Capable of giving written informed consent, which includes compliance with the
requirements and restrictions listed in the consent form
- Patients must have histologically or cytologically confirmed stage IIIB/C or stage IV
oligometastatic melanoma; oligometastatic melanoma is defined as three or fewer areas
of resectable disease excluding central nervous system and bone involvement; patients
with cutaneous, mucosal, acral, ocular or unknown primary melanomas are eligible for
enrollment; for patients with stage IV disease with distant lymph nodes (stage M1a), a
maximum of three separate lymph node sites fit the definition of oligometastatic
disease; resectable tumors are defined as having no significant vascular, neural or
bony involvement; only cases where a complete surgical resection with tumor-free
margins can safely be achieved are defined as resectable
- Patients will have at least one melanoma deposit that can undergo serial biopsy (at
least 2 time points) during the neoadjuvant phase of the protocol; patients must be
willing to provide tumor samples at the time points specified in the Study Procedure
Tables
- All patients must undergo a baseline tumor biopsy; in Arms A and B, tumor biopsy for
PD-L1 testing (PD-L1 positivity is determined by greater than or equal to 1% of cells
staining in the membrane by immunohistochemistry) is required for stratification;
PD-L1 status is not required for enrollment on Arm C; the 28-8 clone for PD-L1 testing
is required for assessment of PD-L1 status; for patients with stage IV disease, site
of tumor biopsy will preferably be from non-lymph node disease site; for PD-L1
testing, the biopsy should contain sufficient tumor content (> 100 tumor
cells/4-micron tissue section); if a sample contains insufficient tumor content, a
re-biopsy will be required to obtain a sample with sufficient tumor content prior to
treatment
- Patients must be medically fit enough to undergo surgery as determined by the treating
medical and surgical oncology team
- Patients who have been previously treated in the adjuvant setting for melanoma will be
eligible for treatment after a 28 day wash-out period

treatment)

normal direct bilirubin) [3 mg/dL for HCC] (within 28 days of first study treatment)
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3.0 x upper
limit of normal (ULN) (=< 5 x ULN for HCC) (within 28 days of first study treatment)
- Albumin >= 2.5 g/dL (within 28 days of first study treatment)
- Creatinine =< 1.5 x ULN OR calculated creatinine clearance >= 40 mL/min OR 24-hour
urine creatinine clearance >= 50 mL/min (within 28 days of first study treatment)

(TTE) (preferred) or multigated acquisition (MUGA) within 6 months from first study
drug administration
- Women are eligible to participate if: non-childbearing potential defined as
pre-menopausal females with a documented tubal ligation or hysterectomy; or
postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a
blood sample with simultaneous follicle stimulating hormone [FSH] > 40 MlU/mL and
estradiol < 40 pg/mL [< 140 pmol/L] is confirmatory); females on hormone replacement
therapy (HRT) and whose menopausal status is in doubt will be required to use one of
the contraception methods if they wish to continue their HRT during the study;
otherwise, they must discontinue HRT to allow confirmation of post-menopausal status
prior to study enrollment; for most forms of HRT, at least 2-4 weeks will elapse
between the cessation of therapy and the blood draw; this interval depends on the type
and dosage of HRT; following confirmation of their post-menopausal status, they can
resume use of HRT during the study without use of a contraceptive method
- A woman of childbearing potential (WOCBP) agrees to use method(s) of contraception;
for a teratogenic study drug and/or when there is insufficient information to assess
teratogenicity, a highly effective method(s) of contraception (failure rate of < 1%
per year) is required; the individual methods of contraception and duration should be
determined in consultation with the investigator; WOCBP must follow instructions for
birth control when the half-life of the study drug is > 24 hours; contraception should
be continued for a period of 30 days plus the time required for the study drug to
undergo 5 half-lives; WOCBP should use an adequate method to avoid pregnancy for 24
weeks (30 days plus the time required for study drug to undergo 5 half-lives) after
the last dose of study drug; WOCBP 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 investigational product
- Women must not be breastfeeding
- Men who are sexually active with WOCBP must use any contraceptive method with a
failure rate of < 1% per year; the investigator shall review contraception methods and
the time period that contraception must be followed; men who are sexually active with
WOCBP must follow instructions for birth control when the half-life of the study drug
is > 24 hours, contraception should be continued for 90 days plus the time required
for the study drug to undergo 5 half-lives; therefore, men who are sexually active
with WOCBP must continue contraception for 33 weeks (90 days plus the time required
for nivolumab and/or relatlimab to undergo 5 half-lives) after the last dose of study
drug; in addition, male participants must be willing to refrain from sperm donation
during this time; men who are sexually active with women who are not of childbearing
potential (i.e., who are postmenopausal or surgically sterile and azoospermic men) do
not require contraception
