- Prior spontaneous CNS hemorrhage (as determined from clinical history, CT, or MRI)

- Uncontrollable hypertension

- Requiring escalating or chronic supraphysiologic doses of corticosteroids (> 4 mg
dexamethasone daily) for control of disease at the time of registration

- Previous or current treatment with an anti-CTLA-4, anti-PD-1, anti-PD-L1, or anti-PDL2
agent.

- Previous or current treatment with bevacizumab

- Hypersensitivity to nivolumab or bevacizumab or any of its excipients

- Diagnosis of immunodeficiency, including Human Immunodeficiency Virus (HIV) or

Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the
skin that has undergone potentially curative therapy or in situ cervical cancer.

- 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 (e.g., thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
form of systemic treatment.

- Known history of, or any evidence of active, non-infectious pneumonitis.

- Active infection requiring systemic therapy.

- Unable to undergo MRI of the brain (i.e. pacemaker or any other contraindication for
MRIs).
