Summary
1. OBJECTIVES 1.1 Primary Objective 1.1.1 Phase II: To determine if adding ipilimumab and nivolumab to radiotherapy significantly prolongs progression-free survival (PFS) versus adding temozolomide to radiotherapy in patients with newly diagnosed glioblastoma (GBM) without MGMT promoter methylation 1.1.2 Phase III: To determine if adding ipilimumab and nivolumab to radiotherapy significantly prolongs overall survival (OS) versus adding temozolomide to radiotherapy in patients with newly diagnosed GBM without MGMT promoter methylation 1.2 Secondary Objectives 1.2.1 To determine if adding ipilimumab and nivolumab to radiotherapy significantly prolongs PFS versus adding temozolomide to radiotherapy in patients with newly diagnosed GBM without MGMT promoter methylation for the phase III part of the study 1.2.2 To determine if adding ipilimumab and nivolumab to radiotherapy significantly increases the 2-year OS rate versus adding temozolomide to radiotherapy in patients with newly diagnosed GBM without MGMT promoter methylation 1.2.3 To evaluate the safety of adding ipilimumab and nivolumab to radiotherapy via comparative frequency between arms of specific adverse events of interest and frequency summaries for all adverse event types 1.2.4 To evaluate the effect of adding ipilimumab and nivolumab to radiotherapy versus adding temozolomide to radiotherapy on patient reported outcomes (PROs), as measured by the MD Anderson Symptom Inventory - Brain Tumor (MDASI-BT) in patients with newly diagnosed GBM without MGMT promoter methylation 1.2.5 To evaluate the effect of adding ipilimumab and nivolumab to radiotherapy versus adding temozolomide to radiotherapy on selected PRO-CTCAE items in patients with newly diagnosed GBM without MGMT promoter methylation 1.2.6 To evaluate the impact of adding ipilimumab and nivolumab to radiotherapy versus adding temozolomide to radiotherapy on neurocognitive function (NCF) in patients with newly diagnosed GBM without MGMT promoter methylation 1.3 Exploratory Objectives 1.3.1 To explore biomarkers in pre-treatment archival tumor tissue that may predict efficacy of ipilimumab and nivolumab as measured by OS, PFS, and 2-year OS rate, such as but not limited to  PDL1 expression  Mutational burden 1.3.2 To explore (in the two treatment separately) whether the MGMT protein expression correlates with clinical outcomes including OS, PFS, and 2-year OS rate 1.3.3 To evaluate if MGMT protein expression may be predictive of differential treatment effects between the two treatment arms
