INTRODUCTION: Antiangiogenic approaches are currently the dominating experimental therapeutic strategy in glioblastoma. First enthusiasm was provoked by promising radiological response rates and an apparent clinical benefit with some of these agents. Major limitations include the modest number of durable responses, the lack of cytotoxic antitumor activity, of synergy when combined with chemotherapy and of an overall survival benefit. AREAS COVERED: We review the rationale as well as preclinical and clinical evidence for the future development of antiangiogenic agents in glioblastoma. The most prominent approach targets VEGF and includes agents such as the VEGF antibody bevacizumab, the VEGF receptor fusion protein aflibercept or the tyrosine kinase inhibitors cediranib and XL-184. Inhibition of angiogenic pathways by small molecules, for example, enzastaurin, or anti-integrin-based approaches, for example, cilengitide, represent alternative strategies. EXPERT OPINION: Enzastaurin and cediranib failed in randomized Phase III trials in recurrent glioblastoma, aflibercept in Phase II. By contrast, bevacizumab was conditionally approved in many countries. Recently completed Phase III trials for bevacizumab and cilengitide in the first-line setting will define the future role of these agents. This intense clinical trial activity reflects the hope that antiangiogenic agents will become part of the limited therapeutic options for glioblastoma.
