A Phase III Study of Radiation Therapy with Temozolomide or Nivolumab Immunotherapy in Patients Newly Diagnosed with Glioblastoma


Full Title

A Randomized Phase 3 Open Label Study of Nivolumab vs Temozolomide Each in Combination with Radiation Therapy in Newly Diagnosed Adult Subjects with Unmethylated MGMT (tumor O-6-methylguanine DNA methyltransferase) Glioblastoma


Temozolomide plus radiation therapy is a standard treatment for glioblastoma (brain cancer), but the cancer often comes back. In this study, researchers want to see if giving the immunotherapy drug nivolumab with radiation therapy is more effective than the standard treatment.

Nivolumab boosts the body’s immune system by targeting a protein on white blood cells called PD-1. PD-1 normally maintains the balance of the immune system by shutting it down at the right time. Some cancers take advantage of this shut-down mechanism by activating PD-1, enabling them to escape attack by the body’s white blood cells. Nivolumab binds to and inactivates PD-1, enhancing the body’s ability to detect and destroy cancer cells. It is used to treat several types of cancer; its use in this study is considered investigational.

Patients will be randomly assigned to receive temozolomide plus radiation or nivolumab plus radiation. Temozolomide is taken orally (by mouth), and nivolumab is given intravenously (by vein).


To be eligible for this study, patients must meet several criteria, including but not limited to the following:

  • Patients must be newly diagnosed with glioblastoma with unmethylated MGMT. The “unmethylated” MGMT marker means the tumor is less likely to respond to temozolomide.
  • Patients may have had prior surgery for glioblastoma, but no other therapy.
  • This study is for patients age 18 and older.
