The primary objective of this study is to determine the 6-month Progression free survival (PFS) when intravenous (IV) AR-67 is administered in adults with confirmed recurrence of GBM who have not recently (> 90 days) recurred after treatment bevacizumab (including patients who've received temazolamide, but no bevacizumab). The primary objective in the rapid bevacizumab failure group (< 90 days) is to determine the 2-month PFS.

|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Male or female age 18 years or older.
- Patient, or legal representative, able to provide study-specific informed consent after risks and benefits of treatment have been explained prior to screening.
- Confined histopathology of World Health Organization (WHO) Grade IV GBM or Gliosarcoma at primary diagnosis or recurrence by local pathology review.
- Unequivocal radiographic evidence of recurrence of tumor by MRI within 14 days prior to enrollment.
- Patients who have progressed, had surgery, and have no measurable disease are eligible as long as they have adequately recovered from the surgery.
- Received prior radiotherapy and temozolomide treatment.
- Received last chemotherapy or biologic therapy treatment ≥14 days before first dose of study drug (≥42 days if nitrosourea or ≥90 days if bevacizumab for the non-bevacizumab failure cohort or therapeutic antibody was administered) or, for daily type regimens, ≥7 days or 5 half-lives of the drugs' pharmacokinetics/dynamics or biologic activities, whichever is longer, before the first dose of study drug. For subjects that have received prior chemotherapy, all toxicities need to have resolved ≤ Grade 1 prior to the administration of study drug. For the patients in the bevacizumab failure cohort, failure must have occurred within the prior 90 days of receiving the last bevacizumab dose.
- Completed radiotherapy ≥90 days before study starts.
- Completed the administration of any investigational agent ≥14 days or 5 half-lives of the drugs' PK/dynamics or biologic activities, whichever is longer, before study starts.
- Karnofsky performance status of ≥60%.
- Recovered to Grade 1 or less from the toxic effects of any earlier intervention.
- Patients receiving EIADs must be switched to non-EIADs at least 14 days prior to study start.
Adequate renal, liver, and bone marrow function according to the following criteria:
- Absolute neutrophil count ≥1500/mcL
- Platelets ≥150,000/mcL
- Total bilirubin within upper limit of normal (ULN)
- Aspartate aminotransferase (AST) ≤ 2.5 X institutional ULN
- Creatinine within normal limits or creatinine clearance ≥ 50 mL/min for patients with creatinine levels above normal limits.
- Demonstrated, in the opinion of the investigator, the ability to follow directions necessary to participate in the clinical trial.
Women of childbearing potential must agree to use acceptable contraceptive methods as follows:
- An intrauterine device with a documented failure rate of less than 1% per year.
- Vasectomized partner who is sterile prior to the female patient's entry and is the sole sexual partner for that female.
- Complete abstinence from sexual intercourse for 14 days before exposure to investigational product, through the dosing period, and for at least 21 days after the last dose of investigational product.
- Double-barrier contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide, or male condom and diaphragm with spermicide).
Note: These methods are to be used consistently and in accordance with both the product label and the instructions of the treating physician. Oral contraceptives are not reliable due to potential drug-drug interactions and should be used with caution if the patient insists on their use as a contraceptive.
- A life expectancy of greater than 2 months.
- Patients on therapeutic Coumadin; however, patients on therapeutic Coumadin that can switch to low molecular weight heparin (LMWH) at least 7 days prior to first dosing will be eligible for study participation.
- Female patients who are pregnant or breastfeeding.
- Prior malignancy other than curatively treated basal cell or cervical carcinoma in situ or adequately treated Stage I or II cancer from which the patient is currently in complete remission and from which the patient has been disease-free for three years.
- Uncontrolled concurrent illness including active infection requiring intravenous antibiotics, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- Known HIV infection.
- Any other condition that would compromise treatment and/or evaluation with reasonable safety.
- Completed intracranial surgery ≤ 14 days before the study starts.
