Clinical Trial Summary

Randomized phase 2 study TVB-2640 in combination with Bevacizumab versus Bevacizumab alone.

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.

Exclusion Criteria:

• Receiving warfarin (or other coumarin derivatives) and is unable to switch to low molecular weight heparin (LMWH) before the first dose of study drug

• Evidence of acute intracranial or intratumoral hemorrhage either by MRI or CT scan. 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

Related Conditions & MeSH terms

• Astrocytoma

Intervention

Drug:
• Bevacizumab
Bevacizumab is FDA approved as a treatment for recurrent Glioblastoma following failure of radiation therapy and temozolomide.
• TVB-2640
TVB-2640 is a potent and reversible inhibitor of the FASN enzyme. TVB-2640 inhibits the ß-ketoacyl reductase (KR) enzymatic activity of the FASN enzyme.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Metabolic Change Analysis of Tumor Tissue by MRS (Magnetic Resonance Spectroscopy)	The MRI was performed during cycle 2. This procedure was intended to be outsourced, and MRIs performed locally produced inadequate resolution, so no data analysis was obtained from this measure.	Cycle 2: approximately 56 days
Primary	Progression Free Survival at 6 Months (PFS6)	Survival of participants at 6 months after the start of treatment without their condition becoming any worse. Brain magnetic resonance imaging (MRI) was performed after every even cycle (e.g., C2, C4) during treatment, with tumor response assessed by the investigator for complete response (CR), partial response (PR) and PD according to the Response Assessment in Neuro-oncology (RANO) criteria.	6 months
Secondary	Incidence, Nature and Severity of Adverse Events and Serious Adverse Events, Graded According to NCI - Common Toxicity Criteria for Adverse Events Version (4.03)	Number of adverse of any nature are reported as well as the number of adverse events that were classed as grade 3-5 on the NCI - Common Toxicity Criteria for Adverse Events	Up to 6 28-day cycles
