Brain cancers, such as glioblastoma (GBM) and anaplastic astrocytoma (AA), often regrow despite initial treatment. Participation in a clinical trial is one possible option for people who have regrowth of these types of brain cancers. It is recommended that patients talk with their doctor to discuss potential participation in a clinical trial.
Tocagen is developing a cancer-selective virus for the treatment of cancer. The company is conducting a clinical trial, called Toca 5, for patients with recurrent GBM or recurrent AA who are planning to have their tumor removed surgically.
