Testing the Use of the Immunotherapy Drugs Ipilimumab and Nivolumab Plus Radiation Therapy Compared to the Usual Treatment (Temozolomide and Radiation Therapy) for Newly Diagnosed MGMT Unmethylated Glioblastoma

Study Overview
=================
Brief Summary
-----------------
This phase II/III trial compares the usual treatment with radiation therapy and temozolomide to radiation therapy in combination with immunotherapy with ipilimumab and nivolumab in treating patients with newly diagnosed MGMT unmethylated glioblastoma. Radiation therapy uses high energy photons to kill tumor and shrink tumors. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Temozolomide, may not work as well for the treatment of tumors that have the unmethylated MGMT. Immunotherapy with monoclonal antibodies called immune checkpoint inhibitors, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is possible that immune checkpoint inhibitors may work better at time of first diagnosis as opposed to when tumor comes back. Giving radiation therapy with ipilimumab and nivolumab may lengthen the time without brain tumor returning or growing and may extend patients' life compared to usual treatment with radiation therapy and temozolomide.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. 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. (Phase II) II. 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. (Phase III) SECONDARY OBJECTIVES: I. 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. II. 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. III. 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. IV. 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. V. To evaluate the effect of adding ipilimumab and nivolumab to radiotherapy versus adding temozolomide to radiotherapy on selected Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE) items in patients with newly diagnosed GBM without MGMT promoter methylation. VI. 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. EXPLORATORY OBJECTIVES: I. 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: Ia. PDL1 expression; Ib. Mutational burden. II. To explore (in the two treatment separately) whether the MGMT protein expression correlates with clinical outcomes including OS, PFS, and 2-year OS rate. III. To evaluate if MGMT protein expression may be predictive of differential treatment effects between the two treatment arms. OUTLINE: Patients are randomized to 1 of 2 arms. ARM 1: Patients undergo radiation therapy for 5 days per week (Monday-Friday) for a total of 30 fractions over 6 weeks and simultaneously receive temozolomide orally (PO) daily for 6 weeks. After radiation, patients may wear the Optune device at the discretion of the patient and their treating physician. Beginning 1 month after radiation therapy, patients receive temozolomide on days 1-5. Treatment repeats every 28 days for up to 12 cycles at the discretion of the treating investigator in the absence of disease progression or unacceptable toxicity. Patients also undergo contrast-enhanced brain magnetic resonance imaging (MRI) throughout the trial. ARM 2: Patients undergo radiation therapy for 5 days per week (Monday-Friday) for a total of 30 fractions over 6 weeks. Starting on the first day of radiation, patients also receive ipilimumab intravenously (IV) over 90 minutes once every 4 weeks (Q4W) for 4 doses and nivolumab IV over 30 minutes every 2 weeks until disease progression. Patients also undergo contrast-enhanced brain MRI throughout the trial. After completion of study treatment, patients are followed up every 3 months for year 1, then every 4 months for year 2, and then every 6 months thereafter.

Eligibility Criteria
-----------------
Inclusion Criteria: PRIOR TO STEP 1 REGISTRATION: No known IDH mutation.

Note that tissue for central pathology review and central MGMT assessment must be received by the New York University (NYU) Center for Biospecimen Research and Development (CBRD) on or before postoperative calendar day 23. If tissue cannot be received by postoperative calendar day 23, then patients may NOT enroll on this trial as central pathology review will not be complete in time for the patient to start treatment no later than 6 weeks following surgery. Results of central pathology review and central MGMT analysis will generally be conveyed to NRG Oncology within 10 business days of receipt of tissue. Note: In the event of an additional tumor resection(s), tissue must be received within 23 days of the most recent resection and the latest resection must have been performed within 30 days after the initial resection. Surgical resection (partial or complete) is required; a limited biopsy is not allowed because it will not provide sufficient tissue for MGMT analysis Note: The central pathology review and central MGMT results determine eligibility. Therefore, patients may be offered the opportunity to consent REGARDLESS of local pathology and MGMT results, and consent can occur BEFORE local pathology interpretation is finalized and BEFORE local MGMT testing is conducted Contrast-enhanced brain MRI within 3 days after surgery MRI with Axial T2 weighted FLAIR {preferred} or T2 turbo spin echo (TSE)/fast spin echo (FSE) and 3-dimensional (3D) contrast-enhanced T1 sequences are required 3D pre contrast-enhanced T1 sequences are strongly suggested Women of childbearing potential (WOCBP) and men who are sexually active with WOCBP must be willing to use an adequate method of contraception hormonal or barrier method of birth control; or abstinence during and after treatment The patient or a legally authorized representative must provide study-specific informed consent prior to study entry PRIOR TO STEP 2 REGISTRATION: Histopathologically proven diagnosis of glioblastoma (or gliosarcoma as a subtype of glioblastoma) confirmed by central pathology review Note: diagnoses of Molecular glioblastoma per the Consortium to Inform Molecular and Practical Approaches to Central Nervous System (CNS) Tumor Taxonomy (c-IMPACT-NOW) criteria or CNS grade 4 per the World Health Organization (WHO) 2021 criteria are NOT relevant MGMT promoter without methylation confirmed by central pathology review. Note: Patients with tissue that is insufficient or inadequate for analysis, fails MGMT testing, or has indeterminate or methylated MGMT promoter are excluded. Note: central pathology review and central MGMT results determine eligibility; local pathology or MGMT results cannot be used for eligibility/randomization Note: patients with methylated MGMT may be considered for enrollment on NRG-BN011 IDH mutation testing by at least one method (such as immunohistochemistry for IDH1 R132H) must be performed as part of standard of care and no mutation must be found (i.e IDH wildtype).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-free survival (PFS) (Phase II) | Analysis will be performed on the intent-to-treat basis. PFS distributions for each treatment group will be estimated via the Kaplan-Meier survival function. Will utilize the PFS resolution guidance provided in the ALLIANCE A071102 (NCT02152982) study, the updated Response Assessment in Neuro-Oncology Criteria (RANO) criteria. | From randomization to disease progress or death, assessed up to 4 years | 
| Overall survival (OS) (Phase III) | Analysis will be performed on the intent-to-treat basis. Overall survival distributions for each treatment group will be estimated via the Kaplan-Meier survival function. | From randomization to death from any cause, assessed up to 4 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| PFS for the entire cohort (Phase II/III) | PFS curves will be estimated via the Kaplan-Meier method and a stratified log-rank test. | Up to 4 years | 
| OS proportion | 2-year OS will be compared between treatment arms, to determine whether the proportion surviving to this landmark is increased in the experimental (ipilimumab [ipi] + nivolumab [nivo]) arm. Estimates will be obtained from the Kaplan Meier curves, and a test comparing the proportion surviving with an appropriate variance term that accounts for censoring (Greenwood's formula) will be used. | At 2 years | 
| Comparative frequency of specific adverse events of interest | Adverse events (AEs) will be graded according to Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 and Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE). | Up to 4 years | 
| Frequency summaries for all adverse event types | Adverse events will be graded according to CTCAE v5.0 and PRO-CTCAE. Comprehensive summaries of all AEs by treatment arm will be generated and examined. Counts and frequencies of worst (highest score) AE per patient will be presented overall and by AE type category, separately by assigned treatment group. Complementing physician-assessed AEs will be selected PRO-CTCAE symptom items that have demonstrated sensitivity to immunotherapy-related toxicities but do not overlap with MDASI-BT. The following PRO-CTCAE symptom items will be monitored: rash, itching, muscle pain, joint pain, headache, chills, mouth/throat sores, skin dryness, hair loss, cough, taste changes, dizziness, swelling, hot flashes. | Up to 4 years | 
| Patient reported symptom burden | Will be assessed using the MD Anderson Symptom Inventory - Brain Tumor (MDASI-BT)-modified. The MDASI-BT consists of 23 symptoms rated on an 11-point ordinal scale (0 to 10) to indicate the presence and severity of the symptom in the last 24 hours, with 0 being not present and 10 being as bad as you can imagine. These interference items include: general activity, mood, work (includes both work outside the home and housework), relations with other people, walking, and enjoyment of life. Complementing MDASI-BT will be selected PRO-CTCAE symptom items that have demonstrated sensitivity to immunotherapy-related toxicities but do not overlap with MDASI-BT. | Up to 4 years | 
| Neurocognitive function (NCF) |  | Up to 4 years | 
| Patient-reported toxicity outcomes | Will utilize the PRO-CTCAE to assess the following items: abdominal pain, rash, itching, muscle pain, joint pain, pain and swelling at injection site, headache, chills, mouth/throat sores, skin dryness, hair loss, cough, taste changes, dizziness, swelling, and hot flashes. | Up to 4 years |
