Genentech, Inc. has submitted an application to the U.S. Food and Drug Administration  for its product Avastin® as a therapy for patients of glioblastoma who have received a treatment previously. If the supplemental Biologics License Application (sBLA) is accepted by the FDA, the drug can be considered for a provisional approval for treatment of cancer and other such deadly diseases. Glioblastoma is the most aggressive form of brain cancer. It has no cure. The study found that Avastin, when as evaluated as a single agent, showed that 43 percent of patients experienced no progression of disease.
