Bevacizumab for the treatment of high-grade glioma: an update after phase III trials

Gliomas are highly vascular and rich in VEGF, which promotes angiogenesis. Bevacizumab is a monoclonal antibody against VEGF, inhibiting angiogenesis by preventing receptor activation. Early Phase II clinical trials using bevacizumab in both newly diagnosed and recurrent high-grade gliomas (HGG) showed promising results, but these have not been confirmed in recent Phase III trials. This review is an update including recently reported Phase II and III study results.
