The combination of nivolumab (Opdivo) plus radiation therapy compared with temozolomide did not improve overall survival (OS) in patients with newly diagnosed O6-methylguanine-DNA methyltransferase (MGMT)-unmethylated glioblastoma multiforme (GBM), missing the coprimary endpoint of the phase III CheckMate-498 trial.1

The ongoing phase III CheckMate-548 trial (NCT02667587) is evaluating nivolumab in combination with radiation therapy and temozolomide in patients with newly diagnosed MGMT-methylated GBM.
