defined as those that can be accurately measured in at least one dimension (longest
diameter to be recorded) as >= 10 mm with CT scan, MRI, or calipers by clinical exam.
All tumor measurements must be recorded in millimeters (or decimal fractions of
centimeters)).

[SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) =<
2.5 x institutional upper limit of normal
- Creatinine within normal institutional limits OR according to Johns Hopkins magnetic
resonance imaging (MRI) policy
- Women of child bearing potential (WOCBP) should use an adequate method to avoid
pregnancy for 5 months plus the time required for nivolumab to undergo approximately
five half-lives) after the last dose of investigational drug; in order for a woman to
be determined not of child-bearing potential, she must have >= 12 months of
non-therapy induced amenorrhea or be surgically sterile
- Men receiving nivolumab and who are sexually active with WOCBP will be instructed to
adhere to contraception for a period of 7 months after the last dose of
investigational product
- Ability to understand and the willingness to sign written informed consent document(s)
Exclusion Criteria:
- Prior chemotherapy within 21 days or 5 half-lives (whichever is shorter) days of
starting treatment
- Prior therapy with investigational drugs within 21 days or at least 5 half-lives
(whichever is shorter) before study administration
- Prior therapy with an anti-PD-1, anti-PD-L1, or anti-PDL-2 antibody

adverse events

- Known history of human immunodeficiency virus
- Active infection requiring therapy, including positive tests for hepatitis B surface
antigen or hepatitis C ribonucleic acid (RNA)
- Active autoimmune disease, history of autoimmune disease or history of syndrome that
required systemic steroids or immunosuppressive medications, e.g. organ, tissue, or
allogenic hematopoietic stem cell transplant (HSCT) recipients. Exceptions include
those with resolved childhood asthma/atopy. Subjects with asthma who require
intermittent use of bronchodilators (such as albuterol) will not be excluded from this
study. Subjects are also 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
- Patients should be excluded if they have a 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
- Use of any vaccines against infectious diseases (e.g. varicella, influenza, etc.) up
to 4 weeks (28 days) before receiving nivolumab
- Prisoners or subjects who are compulsorily detained for treatment of either a
psychiatric or physical (e.g. infectious disease) illness
- Prior radiation doses equivalent to, or greater than, 8000 cGy in 200 cGy fractions
- Any radiation to the target lesions within 6 months of enrollment
- Unable to meet radiation treatment plan parameters
- Unavailable for follow up visits after treatment
- Prior malignancy unless disease free for = 2 years. Curatively treated basal or
squamous cell carcinoma of the skin, totally excised melanoma of stage IIA or lower,
low- or intermediate-grade localized prostate cancer (Gleason sum =7), and
curatively-treated carcinoma in situ of the cervix, breast, or bladder are allowed
regardless.
