Inclusion Criteria

absolute neutrophil count >1,500/microliter (mcL)
Patients who have not passed an interval of at least 6 months may still be eligible if they meet the following criteria: convincing histologic evidence of disease recurrence which is not thought to predominantly represent radionecrosis, standard focal external beam radiation therapy (EBRT) treatment with acceptable doses to tumor and normal tissue which suggest re-irradiation is feasible.

platelets >100,000/mcL
serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) < 2.5 times ULN
Women of childbearing potential must have a negative pregnancy test prior to treatment.
Karnofsky performance status ≥60%
Sign written informed consent.
hemoglobin > 9 g/ dL serum bilirubin < 1.5 times the upper limit of normal (ULN); unless due to Gilbert's syndrome (in which <2 times ULN acceptable)
Recovered to Common Toxicity Criteria for Adverse Effects (CTCAE) grade ≤ 2 from prior therapy toxicities
Stable or decreasing corticosteroid regimen (no increase for 7 days) prior to the start of treatment.
serum Creatinine < 1.5 times ULN
>18 years of age
Clinical laboratory:
Prior history of standard dose focal RT to 60 Gy in 30 fractions or 59.4 Gy in 1.8 Gy fractions, or equivalent or lower doses. Patients who have received prior treatment with non-standard RT dose and fractionation schemes are still eligible, provided they have only received a single course of RT. However, subjects treated with interstitial brachytherapy or single-fraction stereotactic radiosurgery are not eligible for this trial.
Histologically proven glioblastoma multiforme (GBM) that is progressive or recurrent following standard radiation therapy (RT) and temozolomide (i.e., at least "biopsy-proven" recurrent disease). Previous salvage therapies after first recurrence are permitted.
30 days since previous treatment of brain tumor with any other agents.
Measurable contrast-enhancing progressive or recurrent GBM (single or multiple lesions) by MRI imaging with an interval of greater than or equal to 6 months between recurrence and completion of prior radiotherapy.
Women of childbearing potential and men must agree to use adequate contraception.

Exclusion Criteria

corrected QT (QTc) interval ≥ 450 milliseconds (mSec) for males or ≥470 mSec for females. PR interval > 250 mSec for males and females
Treatment with unfractionated heparin. Patients taking an anticoagulant must use warfarin or a low molecular weight heparin.
High-grade (second degree or above) atria-ventricular (AV) block or persistent sinus bradycardia of less than 50 beats per minute (BPM).

Pregnant and/or lactating women
Receipt of other investigational agents or anti-cancer agents within 30 days
Treatment with concurrent enzyme-inducing anti-epileptic drugs (EIAEDs).
Known, active hepatitis.
Anti-arrhythmia medication other than beta-blockers or digoxin.
Known HIV-positivity
Treatment with specified drugs that are substrates of cytochrome 3A4 (CYP3A4), cytochrome 2D6 (CYP2D6), cytochrome 1A2 (CYP1A2)
Serious concurrent infection or medical illness, which would jeopardize the ability of the subject to receive treatment safely.
Systolic blood pressure <100 mm Hg, diastolic <60 mm Hg.
Biopsy-confirmed exclusive radionecrosis after initial GBM therapy.
Concurrent malignancy except curatively treated non-melanoma skin cancer or carcinoma in situ of the cervix, breast, or bladder. Subjects with prior malignancies must be disease-free for ≥ five years.
Requirement for calcium channel blocker for blood pressure control that cannot be switched to an antihypertensive with an alternative mechanism of action. Permitted anti-hypertensive medications include: chlorothiazide, hydrochlorothiazide, atenolol, nadolol, enalapril, lisinopril, eprosartan, and irbesartan.

Patients will receive mibefradil dihydrochloride, which will be dose escalated from 150mg/day until the maximum tolerated dose (MTD) is determined, or until a dose of 350 mg/day is reached using a standard 3 + 3 design.

Patients will receive mibefradil dihydrochloride, which will be dose escalated from 150mg/day until the maximum tolerated dose (MTD) is determined, or until a dose of 350 mg/day is reached using a standard 3 + 3 design. Mibefradil dihydrochloride will be dosed orally in 4 divided doses per day for 17 consecutive days to the MTD. The MTD will be determined according to dose-limiting toxicities (DLTs) graded using the Common Terminology Criteria for Adverse Events version 4.0. Radiation therapy (RT) consists of 5 fractions of 600 centigray (cGy) each, delivered over 2 consecutive weeks for a total dose of 3,000 cGy, using stereotactic, intensity-modulated radiation therapy (IMRT). The primary endpoint of the study is to determine the MTD of mibefradil dihydrochloride when given with concurrent hypofractionated RT. Secondary and tertiary endpoints include evaluating the efficacy of mibefradil dihydrochloride and RT in terms of progression-free survival (PFS) and overall survival (OS), and to perform translational research on resected tumor tissue.
