Safety and Tolerability of Fb-PMT in Recurrent Glioblastoma
Recruiting
Glioblastoma is a highly aggressive and fatal form of primary malignant brain tumor with limited treatment options. fb-PMT affects a large group of cancer cell signaling pathways and thus may be effective in heterogeneous, treatment-resistant tumors such as Glioblastoma. fb-PMT also is actively transported across the blood-brain barrier into the brain. This study is being conducted to determine the dose level for further clinical development of fb-PMT to treat recurrent Glioblastoma.
