4. Have recovered from the effects of surgery, post-operative infection, and other complications before study registration;
5. Have a diagnostic contrast-enhanced MRI or CT scan of the brain performed preoperatively and postoperatively prior to the initiation of radiotherapy, within 28 days prior to MBM-02 administration;
6. If female and of child bearing potential, must be using an effective birth-control method as described in section 3.5;
7. If a male with a female partner of child bearing potential, adequate methods of contraception must be employed as described in section 3.5.

Hepatic:

Total bilirubin ≤ 2 x ULN Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) ≤2 x ULN

Renal:

creatinine clearance (CrCl) ≥ 60 ml/min within 2 weeks prior to registration determined by 24-hour collection or estimated by Cockcroft-Gault formula: CrCl male = \[(140 - age) x (wt in kg)\] \[(Serum Cr mg/dl) x (72)\] CrCl female = 0.85 x (CrCl male)

Exclusion Criteria:

1. Evidence of recurrent GBM or metastases detected outside of the cranial vault;
2. Patients with histone H3 K27M mutation or gliosarcoma;
3. Patients using the Optune device during study drug administration;

8. Diagnosis of midline diffuse glioma (glioblastoma);
9. Insufficient biopsy tissue for full molecular profiling of the tumor;
10. Prior radiation or chemotherapy for glioblastoma or glioma;
11. Prior radiation for cancer of the head and neck that would result in an overlap of radiation fields;
12. Evidence of a significant medical illness, or a psychiatric illness/social situation that would, in the investigator's judgment, make the patient inappropriate for this study;
13. Refractory nausea and vomiting, malabsorption, biliary shunt, or significant bowel resection that would preclude adequate absorption of the study drug;
14. Have had a recent, serious, non-malignant medical complication that, in the opinion of the investigator, makes the individual unsuitable for study participation;
15. Have used an investigational drug within 28 days of the initiation of study treatment;
16. Have a history of a positive blood test for HIV;
17. At the time of screening, have a significant active medical illness which, in the opinion of the investigator, would preclude completion of the study; and
