| Eligibility |
Inclusion Criteria:
- Patients with histologically proven World Health Organization (WHO) grade IV gliomas.
Patients will be eligible if the original histology was a grade II or grade III glioma
as long as a subsequent histological diagnosis of a grade IV glioma is confirmed.
- Patients must have undergone upfront therapy that included a combination of
radiotherapy and concurrent and adjuvant temozolomide.
- Patients must have shown unequivocal radiographic evidence for tumor progression by
MRI scan. A scan should be performed within 10 days prior to registration and on a
steroid dose that has been stable for at least five days. If the steroid dose is
increased between the date of imaging and registration a new baseline MRI is required.
- Patients must have tissue confirmation of histology at the University of Rochester
- Patients with prior therapy that included interstitial brachytherapy or stereotactic
radiosurgery (including gamma-knife or cyber-knife) must have confirmation of true
progressive disease rather than radiation necrosis based upon either PET or Thallium
scanning, MR spectroscopy, MR Perfusion, or surgical documentation of disease. The
decision of which modality to use to make this confirmation will be at the discretion
of the investigator.
- Patients who have undergone re-resection for recurrent disease are eligible but must
have an interval of 7 days prior to starting therapy.
- All patients must sign an informed consent indicating that they are aware of the
investigational nature of this study. Patients must have signed an authorization for
the release of their protected health information.
- Age > 18 years old, and with a life expectancy > eight weeks.
- Karnofsky Performance Status = 70
- Patients must have an interval of at least 28 days from any investigational agent or
from prior cytotoxic therapy, six weeks from prior nitrosureas, three weeks from
procarbazine and two weeks from vincristine.
- Patients must have failed prior radiotherapy and must have an interval of greater than
90 days from completion of initial radiation therapy to study entry.
- WBC > 3,000/µl, ANC > 1,500/mm3, platelet count of > 100,000/mm3, and hemoglobin > 8
gm/dl). Patients must have adequate liver function (SGOT and bilirubin < 1.5 times
ULN), and adequate renal function (creatinine clearance >30ml/min as measured by
Cockroft-Gault formula) <before starting therapy. These tests must be performed within
2 weeks prior to treatment initiation. Eligibility level for hemoglobin may be reached
by transfusion.
- Patients with any number of recurrences are eligible.
- Patients taking tamoxifen for other indications are eligible for the study
Exclusion Criteria:
- Patients who are within 3 months of treatment with radiation and concurrent
temozolomide will not be eligible unless there are new enhancing abnormalities outside
the high dose radiation fields (i.e. beyond the 80% isodose line) or surgical
demonstration of active tumor.
- Patients must not be pregnant and must agree to practice adequate contraception. Women
of childbearing potential must have a negative B-HCG pregnancy test documented within
7 days prior to registration. Women must not be breastfeeding.
- Patients with a history of other cancer (except non-melanoma skin cancer or cancer of
the cervix), unless in complete remission for at least three years are ineligible.
- Concomitant use of enzyme inducing anti-epileptic drugs will be prohibited. These
include phenytoin, phenobarbital, carbamazepine and oxacarbazepine. If patients are on
these at time of study enrollment, drugs can be transitioned to a non-enzyme inducing
anti-epileptic drug at the discretion of the investigator.
- Patients must not have any significant medical illnesses or other history that in the
investigator's opinion cannot be adequately controlled with appropriate therapy or
would compromise the patient's ability to tolerate this therapy.
- Patients must not have any disease that will obscure toxicity or dangerously alter
drug metabolism.
- Patients must not have concurrent use of other tricyclic antidepressants or MAO
inhibitors.
- Patients with lower urinary tract symptoms secondary to benign prostatic hypertrophy
that are refractory to medications
- Active drug or alcohol use or dependence that, in the opinion of the investigator,
would interfere with adherence to study requirements.
- Inability or unwillingness of subject or legal guardian/representative to give written
informed consent.
- Patients with history of myocardial infarction within the past year.
- Patients with prior history of status epilepticus
- Patients with evidence of QTc prolongation greater than 450ms
- Patients receiving strong CYP2D6 inhibitors (bupropion, fluoxetine, paroxetine,
quinidine, terbinafine) will be excluded.
- Patients receiving strong CYP3A4 inhibitors (Clarithromycin, telithromycin,
nefazodone, itraconazole, ketoconazole, atazanavir, darunavir, indinavir, lopinavir,
nelfinavir, ritonavir, saquinavir, tipranavir) will be excluded.
- Patients with history of hypersensitivity to maprotiline.
- Patient meets the cut-off score of = 12 in the PHQ-9 or selects a positive response of
'1, 2, or 3' to question number 9 regarding potential for suicidal thoughts ideation
in the PHQ-9 (independent of the total score of the PHQ-9)
