Patients who were treated with prior bevacizumab but did not progress or experienced significant toxicity, are not eligible 1.9 Previous first line therapy with at least radiotherapy utilizing standard dosing of CNS radiation - for either high-grade or low-grade glial neoplasm 1.10 The following time periods must have elapsed from projected Day 1 dose:
• At least 3 weeks from prior surgical resection

• 13 Negative urine or serum pregnancy within 72 hours prior to registration from any woman of child-bearing potential (WOCBP), defined as any woman physiologically capable of becoming pregnant. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• 14 WOCBP (defined above) must agree to use a highly effective method of contraception (detailed in protocol eligibility) consistently and correctly as described below during study treatment and for 120 days after study discontinuation.
• 15 Male participants must agree to use at least one of the methods of contraception detailed in protocol eligibility starting with the first dose of study therapy through 120 days after the last dose of therapy.

You may not qualify if…

• 1 Recurrent tumor greater than 6 cm in maximum diameter 2.2 Currently participating or plans to participate in another study of an investigational agent or using an investigational device.
• 3 Tumor primarily localized to the brainstem or spinal cord. 2.4 Presence of multifocal tumor, diffuse leptomeningeal or extracranial disease.
• NOTE: Not all instances of multifocal disease will exclude a potential patient; only patients with multifocal sites of active disease will be excluded. (e.g. A patient with a previously treated lesion that remains stable would not be excluded.)

• 24 Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 or with an agent directed to another stimulatory or co-stimulatory T-cell receptor (eg CTLA-4, OX-40, CD137). (These therapies target checkpoint proteins on immune cells called T-Cells.PD-1 = Programmed cell death protein 1. CTLA-4 = cytotoxic T-lymphocyte-associated protein 4. OX-40 - AKA CD134 \& TNFRSF4 = Tumor necrosis factor receptor superfamily, member 4) 2.25 Has received prior Vascular endothelial growth factor (VEGF) or VEGFR inhibitor therapy such as bevacizumab, cediranib, aflibercept, vandetanib, XL-184 (Cabozantinib), sunitinib, etc. (Cohort A only)
