Gene therapy has been explored as a method to treat glioblastoma and while animal models and early phase clinical trials have been successful, as ofall gene therapy drugs that had been tested in phase III clinical trials for glioblastoma had failed.

Another drug product known as Gliadel wafers has been approved by the FDA for the treatment of individuals with GBM as an adjunct to surgery and radiation.

However, metastasis of GBM beyond the central nervous system is extremely unusual. This means that the more intense beams, or the beams giving more radiation, can be directed only at the tumor.
