Inclusion criteria

Inclusion criteria: Safety Lead-in Period -Be at least 18 years of age. -Have a histologically proven Grade 2 or 3 IDH mutant glioma. -Subjects must have disease that has recurred or progressed following radiation and/or chemotherapy or that has not responded to this therapy. -Have a documented IDH1 or IDH2 gene-mutation based on local assessment. -MRI-evaluable disease as assessed by the site radiologist. -Have a KPS >=70. -Have expected survival of at least 3 months. Randomization Period -Be at least 18 years of age. -Have Grade 2 oligodendroglioma or astrocytoma per WHO 2016 criteria -Have had at least 1 prior surgery for glioma (biopsy, sub-total resection, gross-total resection), with the most recent surgery having occurred at least 1 year (-1 month) and not more than 5 years (+3 months) before the date of randomization, and no other prior anticancer therapy, including chemotherapy and radiotherapy and not be in need of immediate chemotherapy or radiotherapy in the opinion of the Investigator. -Have confirmed IDH1 (IDH1 R132H/C/G/S/L mutation variants tested) or IDH2 (IDH2 R172K/M/W/S/G mutation variants tested) gene mutation status disease by central laboratory testing during the Prescreening period and available 1p19q status by local testing (eg, fluorescence in situ hybridization [FISH], comparative genomic hybridization [CGH] array, sequencing) using an accredited laboratory. -Have MRI-evaluable, measurable, non-enhancing disease, as confirmed by the BIRC. -Have a Karnofsky Performance Scale (KPS) score of >=80%.

Exclusion criteria

Exclusion criteria: Safety Lead-in Period -Subjects who received systemic anticancer therapy or radiotherapy =5 half-lives of the investigational agent has elapsed. -Have had prior treatment with bevacizumab (Avastin). Randomization Period -Have had any prior anticancer therapy other than surgery (biopsy, sub-total resection, gross-total resection) for treatment of glioma including systemic chemotherapy, radiotherapy, vaccines, small-molecules, IDH inhibitors, investigational agents, laser ablation, etc. -Have features assessed as high-risk by the Investigator, including brainstem involvement either as primary location or by tumor extension, clinically relevant functional or neurocognitive deficits due to the tumor in the opinion of the Investigator (deficits resulting from surgery are allowed), or uncontrolled seizures (defined as persistent seizures interfering with activities of daily life AND failed 3 lines of antiepileptic drug regimens including at least 1 combination regimen).
