About
This phase I trial studies the side effects and best dose of ascorbic acid when given together with bevacizumab in treating patients with high grade glioma that has come back (recurrent). Monoclonal antibodies, such as bevacizumab may interfere with the ability of tumor cells to grow and spread. Ascorbic acid contains ingredients that may prevent or slow the growth of high grade glioma. Giving bevacizumab and ascorbic acid together may work better in treating patients with high grade glioma.
Full description
PRIMARY OBJECTIVES:
I. To evaluate the toxicities and determine the recommended dose of intravenous ascorbic acid given three times weekly in combination with intravenous bevacizumab every two weeks in patients with recurrent high grade glioma.
SECONDARY OBJECTIVES:
I. To evaluate changes in the levels of serum ascorbic acid (using high performance liquid chromatography [HPLC] with coulometric electrochemical detection) during therapy with ascorbic acid and bevacizumab.
II. Radiographic assessment of disease status after 2 cycles of therapy with ascorbic acid and bevacizumab.
III. To evaluate progression-free and overall survival of patients with recurrent high grade glioma treated with therapy with ascorbic acid and bevacizumab. Patients with stable or responsive disease after every 2 cycles will continue on therapy with ascorbic acid and bevacizumab until intolerance or progressive disease.
IV. To descriptively examine quality of life (QOL) using European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire QLQ-C30 during treatment.
OUTLINE: This is a dose-escalation study of ascorbic acid.
Patients receive ascorbic acid intravenously (IV) over 90-120 minutes three times per week (at least 24 hours apart) and bevacizumab IV over 30-90 minutes on days 1 and 15. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 2 months for 1 year.

Clinically significant cardiovascular disease defined as follows:
Evidence or history of bleeding diathesis (greater than normal risk of bleeding, i.e., Hereditary Hemorrhagic Telangiectasia type I or HHT-1) or coagulopathy in the absence of therapeutic anti-coagulation or any hemorrhage/bleeding event > grade 3 within 4 weeks prior to registration; note: patients with full-dose anticoagulants are eligible provided the patient has been on a stable dose for at least 2 weeks of low molecular weight heparin; therapeutic Coumadin and aspirin doses > 325 mg daily are not allowed

Any other clinically significant medical disease or condition laboratory abnormality or psychiatric illness that, in the Investigator's opinion, may interfere with protocol adherence or a subject's ability to give informed consent
Patients who are on the following drugs and cannot have a drug substitution: flecainide, methadone, amphetamines, quinidine, and chlorpropamide; Note: high dose ascorbic acid may affect urine acidification and, as a result, may affect clearance rates of these drugs
Simultaneous participation in other therapeutic clinical trials will not be allowed
