- Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1.
- Life expectancy > 12 weeks.
- Histological confirmation of chordoma.
- Adequate archival tissue must be available within 6 months prior to signing consent.
If not, an adequate tumor specimen obtained by either excisional biopsy, incisional

cells.

progression by either computed tomography (CT) or magnetic resonance imaging (MRI)
scan, or loss of neurologic function on or after the last cancer therapy within 6
months prior to randomization.
- Measurable tumor lesions according to Response Evaluation Criteria in Solid Tumors
(RECIST) 1.1 criteria.
- Women must not be able to become pregnant (e.g., post-menopausal for at least 1 year,
surgically sterile, or practicing adequate birth control methods) for the duration of
the study. (Adequate contraception includes: oral contraception, implanted
contraception, intrauterine device implanted for at least 3 months, or barrier method
in conjunction with spermicide.)
- Women must not be breastfeeding.
- Males and their female partner(s) of child-bearing potential must use 2 forms of
effective contraception (condom or vasectomy for males) from the last menstrual period
of the female partner during the study treatment and agree to continue use for 6
months after the final dose of study treatment.
- Reproductive status:
- Women of childbearing potential (WOCBP) must have a negative serum or urine
pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human
chorionic gonadotropin [HCG]) at screening.
- Women must not be breastfeeding.
- Women of childbearing potential (WOCBP) must agree to follow instructions for
method(s) of contraception for the duration of treatment with study treatments
plus 24 weeks after the last dose of study treatment.
- Males who are sexually active with WOCBP must agree to follow instructions for
method(s) of contraception for the duration of treatment with study treatments
plus 33 weeks after the last dose of study treatment. Male participants must be
willing to refrain from sperm donation during this time.
- Azoospermic males are exempt from contraceptive requirements. WOCBP who are
continuously not heterosexually active are also exempt from contraceptive
requirements, and still must undergo pregnancy testing as described in this
section.

study and for 5 half-lives of study drug plus 90 days (duration of sperm
turnover) XX days after dosing has been completed.

WOCBP, on the importance of pregnancy prevention and the implications of an
unexpected pregnancy. Investigators shall advise on the use of highly effective
methods of contraception, which have a failure rate of < 1% when used
consistently and correctly.

institutional upper limit of normal (ULN); for subjects with liver metastases, AST or
ALT =< 5 ? ULN.

- Willingness to provide consent for biopsy samples. Tumor biopsies will be required for
all subjects. Tumor lesions used for biopsy should not be lesions used as RECIST
target lesions, unless there are no other lesions suitable for biopsy. If a RECIST
target lesion is used for biopsy the lesion must be >= 2 cm in longest diameter.

randomization; also no steroids are permitted as of 28 days of starting the study.

date of randomization or to any agent for which 5 half lives have not elapsed.
- An inadequate tumor specimen as defined by the central pathologist.
- History of other malignancies except cured basal cell carcinoma, cutaneous squamous
cell carcinoma, melanoma in situ, superficial bladder cancer or carcinoma in situ of
the cervix; for other malignancies, must be documented to be free of cancer for >= 2
years. All other cases can be considered on a case by case basis at the discretion of
the principal investigator.
- Current, serious, clinically significant cardiac arrhythmias or hypertension that is
not adequately controlled, per investigator discretion.
- Concomitant use of medications associated with a high incidence of QT prolongation
will require clearance by medical monitor.
- Active, clinically significant serious infection requiring treatment with antibiotics,
anti-virals or anti-fungals. The Medical Monitor should be contacted for any
uncertainties.
- Any condition that might interfere with the subject?s participation in the study,
safety, or in the evaluation of the study results.
- Concurrent enrollment in another clinical study, unless it is an observational
(non-interventional) clinical study or the follow-up period of an interventional
study.
- Prior exposure to any anti-LAG3 antibodies. (prior PD-1/PD-L1 antibodies are
permitted).
- Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer
treatment. Concurrent use of hormones for non-cancer-related conditions (eg, insulin
for diabetes and hormone replacement therapy) is acceptable.

dose of nivolumab, with the exceptions of intranasal, topical, and inhaled
corticosteroids or systemic corticosteroids at physiologic doses not to exceed 10
mg/day of prednisone or equivalent (use for brain metastases is not permitted 28 days
prior to start of therapy).

months prior to consent.
- Uncontrolled angina within the 3 months prior to consent.
- Any history of clinically significant arrhythmias (such as ventricular
tachycardia, ventricular fibrillation, or torsades de pointes, or poorly

- Cardiovascular disease-related requirement for daily supplemental oxygen.
- History of two or more MIs or two or more coronary revascularization procedures.
- Subjects with history of myocarditis, regardless of etiology.

T-cell co-stimulation or immune checkpoint pathways) except those that are
unlikely to re-occur with standard countermeasures (eg, hormone replacement after
endocrinopathy).
- Troponin T (TnT) or I (TnI) > 2 x institutional ULN. Subjects with TnT or TnI
levels between > 1 to 2 x ULN will be permitted if repeat levels within 24 hours
are 1 x ULN. If TnT or TnI levels are > 1 to 2 x ULN within 24 hours, the subject
may undergo a cardiac evaluation and be considered for treatment, following a
discussion with the BMS medical monitor or designee. When repeat levels within 24
hours are not available, a repeat test should be conducted as soon as possible.
If TnT or TnI repeat levels beyond 24 hours are < 2 x ULN, the subject may
undergo a cardiac evaluation and be considered for treatment, following a
discussion with the BMS Medical Monitor or designee.
