Summary: The goal of this clinical trial is to learn about a type of brain cancer called high-grade glioma. This clinical trial is for people who have previously received treatment for their brain cancer, but their cancer has come back or gotten worse after treatment. The main question this trial aims to answer is: - Is it safe for participants to take bicalutamide while receiving brain radiation treatment? Participants will: - Take bicalutamide every day for 6 months - Receive radiation treatment to the brain - Keep a diary of the when they take the bicalutamide and any side effects they may be experiencing - Visit the clinic once every 8 weeks for checkups and tests

Detailed description: Patients will be enrolled according to a standard cohort 3+3 dose-escalation/de-escalation clinical trial design at a starting dose of 150 mg of bicalutamide. Up to six (6) subjects will be enrolled to a given dose level until the Maximum Tolerated Dose (MTD) is reached, or until a maximum dose of 600 mg is reached. The MTD is defined as the dose below which two (2) or more of six (6) subjects experience a dose limiting toxicity (DLT). If the starting dose exceeds the MTD, the dose will be decreased until a minimum dose of 25 mg is reached. Primary Objective: 1. To evaluate the safety when combining partial brain re-irradiation with bicalutamide. Side effects of the study drug combined with RT will be assessed per CTCAE 5.0. Secondary Objectives: 1. To estimate the rate of objective response (ORR) in subjects with treatment. Response Assessment in Neuro-Oncology (RANO) criteria will be used to estimate ORR. 2. To estimate the 6-month progression-free survival rate. 3. To evaluate the impact of combining bicalutamide with brain re-irradiation on quality of survival, as measured by changes to scores on the Montreal Cognitive Assessment (MoCA) and Karnofsky performance status.

Criteria for eligibility:
Criteria:
Inclusion Criteria: - Histopathologically proven diagnosis of high-grade glioma (HGG) including glioblastoma or variants (gliosarcoma, giant cell glioblastoma etc), World Health Organization (WHO) grade IV, or anaplastic astrocytoma, or anaplastic oligodendroglioma, WHO grade III. Participants will be eligible if the original histology was lower-grade glioma and a subsequent diagnosis of HGG (secondary HGG) is made. - Participants who did not have surgery for their HGG within 5 weeks prior to enrollment must have shown unequivocal radiographic evidence for tumor progression by contrast-enhanced magnetic resonance imaging (MRI) scan (or CT scan for subjects with non-compatible devices). Imaging completed prior to enrollment will be acceptable for eligibility purposes if completed within 4 weeks prior to enrollment. If imaging was not completed within 4 weeks prior to enrollment then imaging must be completed within 14 days after enrollment and prior to the start of RT. Participants unable to undergo magnetic resonance (MR) imaging because of non-compatible devices can be enrolled provided CT scans are obtained and are of sufficient quality. Participants without non-compatible devices may not use CT scans performed to meet this requirement. - Participants must have passed an interval of 6 months or greater between completion of prior radiotherapy and registration. If participants have not passed an interval of at least 6 months, they may still be eligible if they meet one or more of the following criteria: 1. New areas of tumor outside the original radiotherapy fields as determined by the investigator, or 2. Histologic confirmation of tumor through biopsy or resection, or 3. Nuclear medicine imaging, MR spectroscopy, or MR perfusion imaging consistent with true progressive disease, rather than radiation necrosis obtained within 28 days of registration AND an interval of at least 90 days between completion of previous radiotherapy and registration. - Prior history of standard dose central nervous system (CNS) radiation of 60 Gy in 30 fractions or 59.4 Gy in 1.8 Gy fractions, or equivalent or lower doses. - Participants must have recovered from the toxic effects of prior chemotherapy, and there must be a minimum time of 14 days prior to registration from the administration of any investigational agent or prior cytotoxic therapy with the following exceptions: - 14 days from administration of vincristine - 42 days from administration of nitrosoureas - 21 days from administration of procarbazine - Participants having undergone recent resection of their glioblastoma (within 5 weeks prior to enrollment) must have recovered from the effects of surgery. For CNS related core or needle biopsies, a minimum of 7 days must have elapsed prior to enrollment. Residual disease following resection of recurrent glioblastoma is not mandated for eligibility into the study. - o History/physical examination, including neurologic examination, within 14 days prior to enrollment - Eastern Cooperative Oncology Group (ECOG) ≤ 2 within 14 days prior to enrollment - Age ≥ 19 (Age of adults in Nebraska) - Complete blood count (CBC)/differential obtained within 14 days of enrollment, with adequate bone marrow function. Adequate bone marrow reserve as follows: - Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3 Platelets ≥ 75,000 cells/mm3 Hemoglobin ≥ 9.0 g/dl (Note: The use of transfusion or other intervention to achieve Hgb ≥ 9.0 g/dl is acceptable.) Note: If a CBC w/differential was not obtained prior to enrollment it must be completed within 14 days of enrollment and prior to the start of bicalutamide. - Acceptable liver (total bilirubin < 2.0 mg/dL, and glutamic-oxaloacetic transaminase (SGOT) or Aspartate Transferase (AST) < 2.5 times the upper limit of normal) and renal function [serum creatinine < 1.8 mg/dL and calculated creatinine clearance > 30 ml/min (Cockroft-Gault)] within 14 days of enrollment. Note: If labs were not completed prior to enrollment they must be completed within 14 days of enrollment and prior to the start of bicalutamide. • Urine protein: creatinine (UPC) ratio < 1.0 OR urine dipstick for proteinuria ≤ 2+ completed within 14 days of enrollment. If not completed prior to enrollment it must be completed within 14 days and prior to the start of bicalutamide. Note: Participants discovered to have > 2+ proteinuria on dipstick urinalysis at baseline must have a UPC ratio done that is <1.0 to be eligible. If the UPC ratio is ≥ 1.0 then the Participants will undergo a 24-hour urine collection and must demonstrate ≤ 1g of protein in 24 hours to be eligible. If a 24-hour urine collection is necessary it must be completed within 14 days of enrollment and prior to the start of bicalutamide. Note: UPC ratio of spot urine is an estimation of the 24-hour urine protein excretion; a UPC ratio of 1 is roughly equivalent to a 24-hour urine protein of 1 gm. UPC ratio is calculated using one of the following formulas: - [urine protein]/[urine creatinine]: if both protein and creatinine are reported in mg/dL - [(urine protein) x0.088]/[urine creatinine]: if urine creatinine is reported in mmol/L - Participants must not be pregnant (positive pregnancy test) or breast feeding; pregnancy test must be done within 7 days of enrollment and prior to the start of RT. Effective contraception (men and women), i.e., oral contraceptives and/or physical barriers, must be used in Participants of child-bearing potential while on study treatment and for 6 months after. - Participants on full-dose anticoagulants [e.g., warfarin or Low molecular weight heparin (LMW) heparin] must meet both of the following criteria: - No active bleeding or pathological condition that carries a high risk of bleeding (e.g., tumor involving major vessels or known varices) - In-range international normalised ratio (INR) (usually between 2 and 3) on a stable dose of oral anticoagulant or on a stable dose of low molecular weight heparin, within 14 days of enrollment and prior to the start of bicalutamide - Participants must be able to provide study-specific informed consent prior to study entry. Exclusion Criteria: - Infratentorial, or diffuse leptomeningeal evidence of recurrent disease.
