A Phase 2 Study of NanO2(TM) Combined With Radiation and Temozolomide in Patients With Newly Diagnosed GBM

Open to people ages 18 years and up

1. Histologically confirmed, newly diagnosed primary or secondary glioblastoma multiforme.
2. Treatment plan includes 60 Gy of focal radiation administered in 30 fractions, concurrently with temozolomide chemotherapy.
3. Manageable risks associated with potential radiation necrosis in the radiation field, based on size of the field and proximity to eloquent brain regions (as assessed by the investigator).
4. Aged 18 years and older.
5. Karnofsky Performance Status ≥ 70
6. Life expectancy of at least 3 months.
7. Able to undergo gadolinium-enhanced MRI (Gd-MRI) scans.
8. Baseline MRI performed within 7 days before starting study treatment while on a stable or decreasing glucocorticoid dose for at least 7 days before and during the imaging study.
9. Adequate hematologic, renal and hepatic function, as defined by:
   1. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
   2. Platelet count ≥ 75 x 109/L
   3. Hemoglobin ≥ 10.0 g/dl
   4. Serum creatinine < 1.5 x ULN
   5. Total bilirubin within normal limits (≤ 2.5 x ULN if Gilbert's syndrome)
   6. Aspartate transaminase (AST) and Alanine transaminase (ALT) < 2.5 x ULN
10. Women of childbearing potential or men with child-bearing potential partners (unless vasectomized) must agree to use a highly-effective method of birth control from study entry until 4 months after completing study therapy.
11. Ability to understand and the willingness to sign a written informed consent document.

1. Recurrent Glioblastoma
2. Prior treatment for glioblastoma apart from surgical resection.
3. Presence of multi-focal glioblastoma disease that cannot be encompassed into a radiation treatment field that would be safely treated to the prescribed radiation dose.
4. Presence of leptomeningeal disease that cannot be encompassed within a feasible and safe radiation field.
5. Intracranial bleeding, except for stable grade 1 hemorrhage or a post-operative bleed that is clearing.
6. Has not recovered from the adverse effects of surgical resection or biopsy, except for neurological deficits.
7. Subjects who have received any other investigational agent within 4 weeks before enrollment
8. Stroke or transient ischemic attack requiring hospitalization within 6 months before enrollment.
9. Myocardial infarction (MI) within 6 months before enrolment, unstable angina, New York Heart Association (NYHA) class II or greater congestive heart failure, or uncontrolled hypertension (systolic BP > 160 mmHg and/or diastolic BP > 100 mmHg).
10. Known History of Congenital long QT syndrome (12-lead EKG is not required).
11. Clinically significant chronic obstructive pulmonary disease or asthma.
12. Active major infection requiring treatment.
13. A history of other malignancies, except adequately treated non-melanoma skin cancer, curatively treated in-situ cancers or other solid tumors curatively treated with no evidence of disease for ≥ 2 years.
14. Known infection with human immunodeficiency virus or hepatitis B or C virus (testing is not required).
15. Current anticoagulant or antiplatelet therapy, except for prophylactic doses of low molecular weight heparins, low-dose aspirin, rivaroxaban (Xarelto®), apixaban (Eliquis®), or dabigatran (Pradaxa®).
16. History of allergic reactions attributed to compounds of similar chemical composition to NanO2.
17. Women who are pregnant or breast feeding.
18. Inability to comply with study procedures.
19. History or evidence of any other clinically significant condition that, in the opinion of the investigator, would pose a risk to subject safety or interfere with study procedures, evaluation or completion.
20. Known hypersensitivity to any temozolomide component or to dacarbazine (DTIC).
