Exclusion Criteria

Subjects with resolving hemorrhage changes punctuate hemorrhage, or hemosiderin are eligible - Unable to undergo MRI scan (e.g., pacemaker) - Received enzyme-inducing anti-epileptic agents within 14 days of study drug (e.g., carbamazepine, phenytoin, phenobarbital, primidone) - Not recovered to a NCI CTCAE v.4.03 Grade ≤ 1 from AEs (except alopecia and lymphopenia) due to surgery, antineoplastic agents, investigational drugs, or other medications that were administered prior to study drug - Evidence of wound dehiscence - Pregnant or breast-feeding - Clinically significant Dry Eye or necessary contact lens use - Serious intercurrent illness such as: Hypertension (two or more blood pressure readings performed at screening of > 150 mmHg systolic or > 100 mmHg diastolic) despite optimal treatment, Non-healing wound or ulcer, Uncontrolled life threatening cardiac arrhythmias, Untreated hypothyroidism, Uncontrolled active infection, Symptomatic congestive heart failure or unstable angina pectoris within 3 months prior to study drug, Gastrointestinal perforation, abdominal fistula, intra-abdominal abscess within 1 year - Inherited bleeding diathesis or coagulopathy with the risk of bleeding - HIV , Hepatitis B or C documented infections - Received any of the following prior anticancer therapy: Non-standard radiation therapy such as brachytherapy, systemic radioisotope therapy (RIT), or intra-operative radiotherapy (IORT). Note: stereotactic radiosurgery (SRS) is allowed, Non-antiangiogenic therapy (including investigational agents and small molecular kinase inhibitors) within 7 days or 5 half-lives, whichever is shorter, prior to the first dose of study drug, Biologic agents (antibodies, immune modulators, vaccines, cytokines) within 21 days prior to first dose of study drug, Nitrosoureas or mitomycin C within 42 days or metronomic/protracted

ArmDescriptionAssigned Intervention
Experimental
Bevacizumab and TVB-2640 		Bevacizumab every 2 weeks in combination with TVB-2640 dosed at 100mg/m2 daily (rounded to 50mg tab dose), from day 1 until day 28 of the first cycle.
  • Drug: Bevacizumab
    Bevacizumab is FDA approved as a treatment for recurrent Glioblastoma following failure of radiation therapy and temozolomide.
    Other names:
    • Avastin
  • Drug: TVB-2640
    TVB-2640 is a potent and reversible inhibitor of the FASN enzyme. TVB-2640 inhibits the β-ketoacyl reductase (KR) enzymatic activity of the FASN enzyme.
Experimental
Bevacizumab for Cycle 1, then Bevacizumab and TVB-2640 		Bevacizumab alone every 2 weeks, on days 1 and 15 until day 28 of the first cycle, and then receive both Bevacizumab and TVB-2640 for the remainder of their participation in this study.

Detailed Description

Eligible patients will be randomized into 2 separate arms: - Arm number one will receive Bevacizumab every 2 weeks in combination with TVB-2640 from day 1 until day 28 of the first cycle. - Arm number two will receive Bevacizumab alone every 2 weeks, from on days 1 and 15 of the first until day 28 of the first cycle. - MR-Spectroscopy will be obtained on all patients (both arms) at day 28 of first cycle. - Starting on cycle 2 day 1, all patients will converge to a single arm and will continue to receive bevacizumab every 2 weeks in combination with TVB-2640. Every cycle will last 28 days.
