Testing the Addition of an Anti-cancer Viral Gene Therapy, Toca 511/Toca FC, to the Usual Treatment (Temozolomide and Radiation Therapy) for Newly Diagnosed Glioblastoma

Resumen breve

This phase II/III trial studies how well vocimagene amiretrorepvec (Toca 511) and extended release flucytosine (Toca FC) work when added to the usual treatment (temozolomide and radiation therapy) in treating patients with newly diagnosed glioblastoma. Toca 511 is a live virus that has been built to carry a gene into tumor cells. This gene carries instructions that cause the tumor cells to turn Toca FC, typically used to treat fungal infections, into a drug that may kill the tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving Toca 511 and Toca FC in addition to the usual treatment (temozolomide and radiation therapy) may help shrink or stabilize cancer or extend the life of patients with newly diagnosed glioblastoma.
