12. Women of childbearing potential must have a negative serum pregnancy test within 24
hours prior to the first dose of study treatment and agree to use appropriate highly
effective methods of contraception, during the study and for 5 months following
completion of study treatment; A "Woman of childbearing potential" is defined as any
female who has experienced menarche and who has not undergone surgical sterilization
(hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is
defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of
other biological or physiological causes. In addition, women under the age of 62 must
have a documented serum follicle stimulating hormone (FSH) level less than 40
milli-international units per milliliter (mIU/mL).
Female Subjects:
Women of child bearing potential are expected to use one of the highly effective
methods of contraception listed in the protocol.
Male Subjects:
Male subjects must inform their female partners who are women of child bearing
potential of the contraceptive requirements and are expected to adhere to using
contraception with their partner. Female partners of male subjects, who are women of
child bearing potential, are expected to use one of the highly effective methods of
contraception listed in the protocol. In addition, male subjects are expected to use a
condom as noted in the protocol.
13. Men with a female partner of childbearing potential must agree to use highly effective
methods of contraception or any contraceptive method with a failure rate of less than
1% per year during the study and for 7 months following completion of study treatment.
14. Ability to sign informed consent.
Exclusion Criteria:
1. Active second malignancy, i.e. patient known to have potentially fatal hematologic
malignancy or another solid primary tumor present for which he/she may be (but not
necessarily) currently receiving treatment. Patients with a prior or concurrent
malignancy whose natural history or treatment does not have the potential to interfere
with the safety or efficacy assessment of the investigational regimen are allowed to
enroll in this trial. For example, patients with early-stage skin cancers, prostate
cancer under surveillance with non-rising prostate-specific antigen (PSA), or
meningioma or thyroid papillary cancers which are under surveillance are eligible. For
determinations of a specific clinical condition, please consult with the Principal
Investigator.
2. Active, untreated central nervous system (CNS) metastases;
3. Prior treatment with any other anti-programmed cell death protein-1 (anti-PD-1), or PD
Ligand-1 (PD-L1) or PD Ligand-2 (PD-L2), anti-cytotoxic T-lymphocyte-associated
protein-4 (CTLA-4) antibody, or any other antibody or drug specifically targeting
T-cell costimulation or immune checkpoint pathways, or cancer vaccine;
4. Prior systemic cytotoxic therapy, antineoplastic biologic therapy, or major surgery
within 28 days of first dose of study medication;
5. Severe hypersensitivity reaction to treatment during prior administration of a
monoclonal antibody (mAb) or history of allergy to any study drug component;
6. Has received a live-virus vaccination within 30 days of planned treatment start;
7. Condition requiring systemic treatment with either corticosteroids (> 10 mg daily
prednisone equivalents) or other immunosuppressive medications within 14 days of study
drug administration; Inhaled or topical steroids and adrenal replacement doses > 10 mg
daily prednisone equivalents are permitted in the absence of active autoimmune
disease.
8. Any evidence of current interstitial lung disease (ILD) or pneumonitis or a prior
history of ILD or pneumonitis requiring oral or IV glucocorticoids;
9. Active, known, or suspected autoimmune disease or any autoimmune condition that has
required systemic treatment in the past 2 years (replacement therapies for hormone
deficiencies are allowed); Subjects are permitted to enroll if they have vitiligo,
type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only
requiring hormone replacement, psoriasis not requiring systemic treatment, or
conditions not expected to recur in the absence of an external trigger.
10. Clinically active diverticulitis, intra-abdominal abscess, gastrointestinal (GI)
obstruction, or abdominal carcinomatosis (known risks factors for bowel perforation);
11. Signs or symptoms of infection within 2 weeks prior to first day of study treatment.

13. Received therapeutic oral or IV antibiotics within 2 weeks prior to first day of study
treatment: Patients receiving prophylactic antibiotics (eg, to prevent a urinary tract
infection or chronic obstructive pulmonary disease exacerbation) are eligible.
14. Known positive test for human immunodeficiency virus (HIV);
15. Known active hepatitis B or hepatitis C virus (HBV or HCV): Patients with past or
resolved HBV infection (defined by a negative hepatitis B surface antigen (HBsAg) test
and a positive anti-hepatitis B core antigen (HBc) (anti-HBc)antibody test) are
eligible. HBV DNA must be obtained in these patients prior to first day of study
treatment. Patients who have been recently discovered to have HBV with positive HBsAg
test and positive anti-HBc antibody test but who have been started on antiretroviral
treatment with nondetectable HBV DNA are eligible. HBV DNA must be obtained in these
patients prior to first day of study treatment
16. Patients with known active hepatitis C virus ribonucleic acid (HCV antibody)
indicating acute or chronic infection: Patients positive for HCV antibody are eligible
only if Polymerase chain reaction (PCR) test is negative for HCV RNA.
17. Prior radiation therapy of any type within 7 days of first dose of study medication;
18. Prior radiation therapy to head and neck region that would overlap with intended
radiation treatment for nasopharyngeal carcinoma;
