This conversion to full approval was based on the totality of evidence of Avastin in glioblastoma, including data from the phase III EORTC 26101 study. Avastin is now approved in the United States for nine distinct uses across six different types of cancer.

EORTC 26101 is an independent phase III, multicenter, randomized, open-label trial, conducted by the European Organization for Research and Treatment of Cancer, that evaluated the addition of Avastin to lomustine chemotherapy in 432 patients with previously treated glioblastoma. The primary endpoint of the study was overall survival, and progression-free survival as assessed by investigator and overall response rate were key secondary endpoints.

Results showed the following:
