What the trial is, and whether it could suit you
Almost all gliomas relapse. After temozolomide rechallenge or combination with irinotecan, the progression-free survival rate at 6 months (PFS-6%) of recurrent glioblastoma was about 21%. After treatment with irinotecan-based chemotherapy regimen, the PFS-6% of recurrent lower-grade gliomas was 40%. The optimal chemotherapeutics of recurrent gliomas has yet to be determined.
Anti-angiogenesis is a promising therapeutic strategy. Vascular endothelial growth factor-A (VEGF) is the primary driver of angiogenesis in tumors. Bevacizumab, a humanized monoclonal antibody directed against VEGF, is the prototypical anti-angiogenic drug and received accelerated approval of the United States Food and Drug Administration (FDA) for the treatment of recurrent glioblastoma. Bevacizumab inproved the PFS-6% (36%), but had no effect on the overall survival (OS) (9.2 months). Moreover, the effects of beva
