Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical trial is testing the safety and efficacy of NanO2TM administered via intravenous infusion in combination with standard radiation and chemotherapy.

NanO2TM is being developed to increase the amount of oxygen delivered to tumors which is hoped to increase the effectiveness of radiation therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All study participants will receive standard care for GBM including Temozolomide and radiation therapy. Subjects will be randomized on a 2 to 1 basis to receive either NanO2 infusions or saline infusions immediately prior to standard radiation therapy. Radiation therapy is performed 5 days a week for 6 weeks.

Radiation therapy is followed 28 days of recovery, and then six cycles of maintenance Temozolomide therapy on days 1 to 5 of six 28 day cycles.

Follow up will be every 3 months for 3 years, and then every 6 months for another 2 years.

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

Exclusion Criteria

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).

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).
