NCT02202993 : TAU-2014-1: Mibefradil and Hypofractionated Re-Irradiation Therapy in Recurrent GBM
PhasePhase 1
AgesMin: 18 Years Max: 80 Years
Inclusion Criteria:

- Sign written informed consent.

- 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.

- 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.

- 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.

- 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

- Karnofsky performance status ?60%

- Clinical laboratory:

- absolute neutrophil count >1,500/microliter (mcL)

- platelets >100,000/mcL

- 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)

- serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) < 2.5 times

- serum Creatinine < 1.5 times ULN

- Women of childbearing potential and men must agree to use adequate contraception.

- Women of childbearing potential must have a negative pregnancy test prior to

- Recovered to Common Toxicity Criteria for Adverse Effects (CTCAE) grade ? 2 from
prior therapy toxicities

- 30 days since previous treatment of brain tumor with any other agents.

- Stable or decreasing corticosteroid regimen (no increase for 7 days) prior to the
start of treatment.

- >18 years of age

Exclusion Criteria:

- 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.

- Biopsy-confirmed exclusive radionecrosis after initial GBM therapy.

- Receipt of other investigational agents or anti-cancer agents within 30 days

- 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.

- 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.

- Known, active hepatitis.

- corrected QT (QTc) interval ? 450 milliseconds (mSec) for males or ?470 mSec for
females. PR interval > 250 mSec for males and females

- High-grade (second degree or above) atria-ventricular (AV) block or persistent sinus
bradycardia of less than 50 beats per minute (BPM).

- Known HIV-positivity

- Pregnant and/or lactating women

- Anti-arrhythmia medication other than beta-blockers or digoxin.

- Treatment with concurrent enzyme-inducing anti-epileptic drugs (EIAEDs).

- Treatment with unfractionated heparin. Patients taking an anticoagulant must use
warfarin or a low molecular weight heparin.

- Treatment with specified drugs that are substrates of cytochrome 3A4 (CYP3A4),
cytochrome 2D6 (CYP2D6), cytochrome 1A2 (CYP1A2)
