Arms of the Study
Arm 1
Experimental
Optune+Pulsed Bevacizumab
The subjects will undergo 12 months of planned continuous treatment with Optune. The treatment will begin at week 0 and will be continuous throughout the study. Pulsed bevacizumab dosing is defined by at least one cycle on and at least one cycle off. A cycle is defined as 8 weeks in length. If after one cycle on, there is no evidence of a repeat response; bevacizumab will be continued for one more cycle. If after two cycles on, there is no repeat response; bevacizumab will be continued with or without other standard chemotherapy until death. If after at least one cycle on, there is evidence of repeat response, bevacizumab will be discontinued for at least one cycle. In addition, the following will be performed: Bevacizumab will be given, physical examination and quality of life questionnaires will be performed and brain MRI.
