Serum creatinine =< 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine clearance >= 40 mL/min creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl]) (within 16 days of treatment initiation).

Creatinine clearance should be calculated per institutional standard.

Female subject of childbearing potential should have a negative serum pregnancy at screening.
Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 5 months following the last dose of nivolumab. Subjects should agree to ongoing pregnancy testing during the course of the study and after the end of study therapy. Female subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 7 months following the last dose of nivolumab. Males must refrain from donating sperm during study participation and for 7 months after the last dose of nivolumab.

During study participation, subjects may receive systemic or enteric corticosteroids as needed for treatment-emergent comorbid conditions.

Richter?s transformation from chronic lymphocytic leukemia (CLL).
Major surgery within 3 weeks prior to start of study treatment.
Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Conditions expected to not recur in the absence of an external trigger.
Has an active infection requiring intravenous systemic therapy or uncontrolled systemic infection including viral, bacterial, or fungal.

Double-barrier method (condom + diaphragm or cervical cup with spermicidal contraceptive sponge, jellies, or cream)
Non-vasectomized male patients must comply with at least one of the following methods of birth control throughout the duration of study participation and for at least 3 months after study treatment:
