Nivolumab and Temozolomide Versus Temozolomide Alone in Newly Diagnosed Elderly Patients With GBM

Study details: Participants will be allocated to either experimental or control group in a 2:1 ratio by chance (randomly). Patients assigned to the experimental group will receive a course of nivolumab via intravenous infusion (240 mg on days 1 and 15 every 28 days for cycles 1-4; then 480 mg day 1 every 28 days for cycles 5-6) in addition to the standard regimen of Temozolomide (TMZ) tablets and radiotherapy. Patients assigned to the control group will receive the standard treatment of adjuvant temozolomide (150-200mg/m2 days 1-5 every 28 days) for 6 cycles and standard radiotherapy treatment (40 Gy administered in 15 fractions).
