This study tests the effect of the immunotherapy drugs Ipilimumab and Nivolumab in patients with recurrent glioma, a brain tumor, that has a high mutational burden. It enrolled patients aged 18 and over with histologically confirmed glioblastoma at first or second recurrence whose tumor mutational burden was above a set threshold. The study is in Phase 2 and is currently not recruiting but is still ongoing (active, not recruiting).
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.

Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria:
* PRE-REGISTRATION ELIGIBILITY CRITERIA:
* Histologically confirmed glioblastoma (World Health Organization \[WHO\] grade IV) presenting at first or second recurrence including secondary glioblastoma
* Glioblastoma IDH-wildtype central nervous system (CNS) WHO grade 4
* Diffuse, astrocytic glioma IDH-wildtype with one or more of the following histological or genetic features: microvascular proliferation, necrosis, TERT promoter mutation, EGFR gene amplification, +7/-10 chromosome copy-number changes
* Astrocytoma, IDH-mutant CNS WHO grade 4
* Diffuse astrocytic glioma IDH-mutant (with frequent ATRX and/or TP53 mutation and absence of 1p/19q codeletion), with necrosis and/or microvascular proliferation or one with lower grade histological features displaying homozygous deletion of CDKN2A and/or CDKN2B
* NOTE: The eligibility criteria were changed to include the new diagnostic language from the WHO 2021 pathology classification change. The above diagnoses therefore reflect the change and include the entities that were previously eligible but now carry updated pathologic classification
* Presence of measurable disease, as defined by a bidimensionally measurable lesion on magnetic resonance imaging (MRI) with a minimum diameter of 10 mm in both dimensions, prior to resection or biopsy of recurrent tumor
* Tissue available from surgical resection or biopsy of recurrent tumor =\< 28 days prior to pre-registration, or planned surgery or biopsy of recurrent tumor =\< 28 days after pre-registration
* Does not require \> 4 mg dexamethasone beyond the perioperative period defined as the time =\< 2 weeks after surgical procedure
* No active autoimmune disease or history of autoimmune disease
* These include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded because of the risk of recurrence or exacerbation of disease
* Patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible
* No prior treatment with checkpoint blockade therapies (anti-CTLA4, anti-PD1/PD-L1) or bevacizumab
* No prior treatment with laser ablation at the time of recurrent tumor tissue sampling. Patients who have previously undergone laser ablation \>= 4 months prior to recurrent tumor tissue sampling can be included
* Age \>= 18 years
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 2
* Able to undergo brain MRI with contrast
* Absolute neutrophil count \>= 1500/mm\^3
* Platelet count \>= 100,000/mm\^3
* Total bilirubin =\< 1.5 x upper limit of normal (ULN)
* If Gilbert syndrome, then total bilirubin =\< 3 x ULN
* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =\< 2.0 x ULN
* Creatinine =\< 1.5 x ULN OR creatinine clearance (CrCl) \>= 50 mL/min (if using the Cockcroft-Gault formula)
* History of active malignancy (outside of the patient's glioblastoma) that has required treatment within the previous 2 years. Participant with prior history of in situ cancer or basal or squamous cell skin cancer are eligible
* REGISTRATION ELIGIBILITY CRITERIA: Tissue obtained from biopsy or resection at first or second recurrence exhibits TMB \>= 10 on FoundationOne CDx testing
