This is an interventional treatment trial for Glioblastoma Read More

Inclusion Criteria:

1. The subject has histologically confirmed diagnosis of primary GB for which the subject has received prior treatment, including radiation and/or chemotherapy, and will be undergoing a second surgical resection.
2. The subject has available archival tumor tissue from the time of initial diagnosis of GB that is designated for central laboratory analysis.
3. The subject is ≥ 18 years old.
4. The subject has a Karnofsky performance status (KPS) ≥ 60%.
5. The subject has adequate organ and marrow function.
6. The subject has adequate fasting plasma glucose levels and glycosylated hemoglobin levels.
7. The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document.
8. Sexually active subjects (men and women) must agree to use medically-accepted barrier methods of contraception during the course of the study and for 3 months after the last dose of study drug, even if oral contraceptives are also used. All subjects of reproductive potential must agree to use both a barrier method and a second method of birth control.
9. Women of childbearing potential must have a negative pregnancy test at screening.

Exclusion Criteria:

1. The subject has confirmed secondary GB (ie, had a pathology-confirmed lower-grade glioma that subsequently recurred as a higher grade glioma).
2. The subject's tumor has a predominance of WHO Grade IV oligoastrocytoma.
3. The subject has received radiation therapy for GB within 12 weeks (≤ 84 days) before their first dose of study drug treatment.
4. The subject has received specific types of anticancer therapy (should be discussed with the treating physician)
5. The subject has not recovered to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 Grade ≤ 1 from AEs due to surgery, radiation, antineoplastic agents, investigational drugs, or other medications that were administered before screening (except Grade 2 alopecia and Grade 2 lymphocytopenia).
6. The subject is receiving > 1 mg/day warfarin (or equivalent of other coumarin derivatives) and is unable to switch to low molecular weight heparin within 14 days before the first dose of study drug.
7. The subject is receiving enzyme-inducing anti-epileptic agents (EIAED; eg, carbamazepine, phenytoin, phenobarbital, or primidone) or valproic acid and is unable to convert to EIAED anti-seizure agents within 14 days before the first dose of study drug.

8. The subject has uncontrolled intercurrent illness including, but not limited to:

   • Ongoing or active infection
   • Hypertension (consistent blood pressure readings of > 140 mmHg systolic or > 100 mmHg diastolic) despite optimal treatment
   • Significant cardiac arrhythmias, or a recent history of serious disease, such as either symptomatic congestive heart failure or unstable angina pectoris within 3 months, or the following events within 6 months: myocardial infarction, stroke, or transient ischemic attack.
   • Inherited or acquired bleeding diathesis
9. The subject has a baseline corrected QT interval (QTc) > 460 ms.
10. The subject is unable to undergo repeated magnetic resonance imaging (MRI) scans for any reason (eg, cardiac pacemaker or ferromagnetic metal implants).
11. The subject is known to be positive for the human immunodeficiency virus (HIV). Note: HIV testing is not required for eligibility.
12. The subject has impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of study treatment (eg, ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).
13. The subject is pregnant or breastfeeding.
14. The subject has a previously identified allergy or hypersensitivity to components of the study treatment formulation.
