Eligibility

Inclusion Criteria

1. Must be 18 years or older at the screening visit.

2. Histologically proven GBM (as defined in 2021 WHO Classification of Tumors of the Central Nervous System; Louis, Perry, et al. 2021) that has recurred or progressed, and for which resection is not indicated.

3. Tumor must be located in the supratentorial or cerebellar region. Tumors with infratentorial locations require consultation with the Sponsor/Medical Monitor to confirm suitability for treatment.

4. Previous treatment with standard of care radiotherapy (RT) and temozolomide (temozolomide required only if tumor has at least partial methylation of the O6-methylguanine-DNA methyltransferase promoter). Temozolomide should be administered concurrent with RT and adjuvantly for newly diagnosed disease unless intolerant or ineligible for treatment.

5. No recurrence within 4 weeks of completion of RT, defined from the imaging assessment immediately after completion of RT.

6. Up to two prior systemic treatments for recurrent or progressing disease.

7. If receiving corticosteroids, must be maintained on a stable or decreasing dosage of steroids for at least 7 days prior to C1D1.

8. Karnofsky Performance Score (KPS) = 70 assessed within 14 days of C1D1.

9. Must have adequate organ and marrow function as defined below:

• Absolute neutrophil count = 1.5 ×10?/L (1,500/µL), without the use of myeloid growth factors (e.g., granulocyte-colony stimulating factor) within 7 days prior to C1D1 for short acting growth factors and 14 days for long-acting growth factors to meet eligibility.

• Platelets = 75 × 10?/L (100,000/µL), unsupported, defined as no platelet transfusion within 7 days prior to C1D1.

• Hemoglobin = 9 g/dL maintained without the need for erythropoietin stimulating agents; subjects that require transfusion or growth factors need to demonstrate stable hemoglobin of = 9 g/dL over at least a 7-day period immediately prior to C1D1.

• Total bilirubin = 1.5 times institutional upper limit of normal (ULN), in subjects with Gilbert syndrome, total bilirubin >1.5 ULN as long as direct bilirubin is normal.

• ALT (SGPT) < 3 x institutional ULN.

• AST (SGOT) < 3 x institutional ULN.

• Albumin = 3 g/dl.

• Potassium = lower limit of normal (LLN).

• Serum total calcium (correct for serum albumin) or ionized calcium = LLN.

• Estimated creatinine clearance (CrCl) by the Cockcroft-Gault (C-G) equation or measured = 60 mL/min. Actual body weight will be used for calculation of the C-G equation. If estimated CrCl is abnormal, accurate measurement should be obtained by 24-hour urine collection to measure CrCl.

10. All colony-forming growth factor(s) (i.e., filgrastim, sargramostim or erythropoietin) must have been discontinued for at least 7 days prior to C1D1 or 14 days if pegylated (PEG) formulations were received.

11. Have a life expectancy of at least 12 weeks.

12. An understanding, ability, and willingness to fully comply with study procedures and restrictions.

13. Ability to provide written, signed, and dated (personally or via a legally authorized representative) informed consent at screening as applicable to participate in the study.

14. Females of childbearing potential (FOCP) must have a negative serum pregnancy test at screening. Subjects of childbearing or child-fathering potential must be willing to use highly effective birth control during the entire study. Acceptable forms of birth control include hormonal contraceptives (oral, depot, injectable, transdermal, or intravaginal) or intrauterine device (IUD) for at least one week prior to study treatment, condom and spermicidal or diaphragm and spermicidal. Other acceptable forms of birth control include a) abstinence for subjects who are not sexually active or b) if the subject is in a monogamous relationship with a partner who is sterile (e.g., vasectomy performed at least 6 months prior to subject's first study treatment). Subjects who become sexually active or begin to have relations with a partner who is not sterile during the trial must agree to use an effective form of birth control for the duration of the study. FOCP taking hormonal therapy must be on treatment for at least 12 weeks prior to C1D1 and must not change their dosing regimen during the study.

7. Use of fish oil supplements within 24 hours of C1D1 is allowed if the subject's clotting parameters fall within normal limits.

8. Use of blood thinning agents within 7 days prior to C1D1. Subjects whose medical condition does not permit discontinuation of this therapy are excluded.
