This is a prospective, open-label single-arm, exploratory, two-stage design trial, aiming to investigate safety and efficacy of AK105 with anlotinib and radiotherapy adjuvant therapy in MGMT unmethylated newly diagnosed glioblastoma.


Glioblastoma is the most common and aggressive primary brain tumor in adults. Treatment usually involves surgery, after which chemotherapy and radiation therapy are used. The Central Brain Tumor Registry of the United States (CBTRUS) Statistical Report primary brain and other central nervous system tumors diagnosed in the United States in 2012-2016, glioblastoma accounted for 48.3% of primary malignant brain tumors.

The Stupp protocol has become standard of care for the treatment of newly diagnosed GBM, however, some MGMT unmethylated glioblastomas are still resistant to temozolomide.

Immunotherapy is being studied as treatment for the cancer, AK105 is a humanized monoclonal antibody that specially binds to PD-1. Anlotinib hydrochloride is a multi-target receptor tyrosine kinase inhibitor. Based on the mechanism study, tumor vascular abnormalities promote tissue hypoxia and increase lactic acid, thereby activating immunosuppression and inhibiting T cell function. Anti-angiogenic drugs enhance the infiltration of effector immune cells by inducing normalization of blood vessels and reducing immunosuppression.
