Maximum Age

Inclusion Criteria:

  • Have Karnofsky Performance Status (KPS) of ≥ 70%.
  • Have expected survival of ≥ 3 months.
  • Have histologically confirmed Grade 2 or Grade 3 astrocytoma (per the 2016 or 2021 World Health Organization [WHO] Classification of Tumors of the central nervous system)
  • Have documented IDH1-R132H gene mutation and for Astrocytomas: Absence of 1p19q co-deletion (i.e., exclusion of combined whole-arm deletions of 1p and 19q) and/or documented loss of nuclear ATRX expression or ATRX mutation by local testing. For Oligodendrogliomas: Presence of 1p19q co-deletion (i.e., combined whole-arm deletions of 1p and 19q) by local testing.
  • Have measurable, magnetic resonance imaging (MRI)-evaluable, unequivocal contrast enhancing disease as determined by institution radiologist/Investigator at Screening on either 2D T1 post-contrast weighted images or 3D T1 post-contrast weighted images. Per mRANO criteria, measurable lesion is defined as at least 1 enhancing lesion measuring ≥ 1 cm x ≥ 1 cm.
  • Have recurrent or progressive disease and received prior treatment with chemotherapy, radiation, or both.
  • Surgical resection is indicated for treatment, but surgery is not urgently indicated (e.g., for whom surgery within the next 6-9 weeks is appropriate). (NOTE: This criterion only applies to participants enrolled in the perioperative phase of the study. Participants in the Safety Lead-In should not require surgery).

Exclusion Criteria:

  • Have received prior systemic anti-cancer therapy within 1 month of the first dose of IMP, radiation within 12 months of the first dose of IMP, or an investigational agent < 14 days prior to the first dose of IMP. In addition, the first dose of IMP should not occur before a period of ≥ 5 half-lives of the investigational agent has elapsed.
  • Have received 2 or more courses of radiation.
  • Have received any prior treatment with an isocitrate dehydrogenase (IDH) inhibitor; anti-programmed cell death 1 (PD1), anti-programmed cell death ligand 1 (PD-L1), or anti-PD-ligand 2 (L2) agent, or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., CTLA-4, OX 40, CD137); any other checkpoint inhibitor; bevacizumab; or any prior vaccine therapy.

Note: Other inclusion and exclusion criteria may apply.
