Dietary Methionine Restriction Plus Temozolomide for Recurrent GBM
Objectives: 1. To determine the safety, tolerability and efficacy of dietary methionine restriction for 7 days alternating with Temodar® (Temozolomide) given once a day for seven days and this repeated for up to one year in the treatment of patients with recurrent and/or progressive glioblastoma. 2. To determine the short- and long-term toxicity of dietary methionine restriction combined with Temodar® in glioblastoma patients. 3. To measure and correlate patients' tumor responses and progression-free survival with: serum methionine and peripheral blood lymphocyte methylation levels. In any patient undergoing surgery, to measure tumor...

Discerning Pseudoprogression vs True Tumor Growth in GBMs
One-third of all primary brain tumors are astrocytomas, the most common type of glioma. Grade 4 astrocytomas, more commonly known as glioblastomas (GBMs), represent about 50% of all gliomas (annual incidence of over 3 per 100,000) and are associated with high mortality rates and median patient survival of just 12-15 months post-diagnosis. Treatment response is assessed by measuring post-treatment tumor size on contrast-enhanced magnetic resonance images (MRI). However, radiation and chemotherapy cause inflammatory and necrotic changes which, like actual tumor progression itself, demonstrate contrast enhancement on the first post-treatment MRI scan. This enhancement eventually...

Disulfiram and Copper Gluconate With Temozolomide in Unmethylated Glioblastoma Multiforme
One of Disulfiram antitumor effects suggested in preclinical studies is MGMT (methyl-guanine-methyl-transferase) inhibition. Disulfiram MGMT inhibitory effect is enhanced by addition of Copper. This study evaluates the impact of Disulfiram (DSF) + Copper (Cu) combination when added to standard Temozolomide in the treatment of unmethylated Glioblastoma Multiforme (GBM) patients.

Dose Escalated MRSI Guided Radiation Therapy in Glioblastoma
In summary, the overall prognosis of glioblastoma (GBM) patients remains poor. Although clinical gains have been achieved in the past, these have been modest, with a majority of patients succumbing to local disease progression within 2 years. New strategies for treatment need to be identified which enhance local control above the current treatment regimen in order to achieve further clinical gains in this disease. Favorable early experience with magnetic resonance spectroscopy imaging (MRSI) demonstrates that metabolic imaging can identify active tumor beyond standard MRI as well as high risk regions at risk for local failure. There is also clinical evidence that limited...

Early Detection of Glioblastoma Multiforme (GBM) Treatment Responses Using Multiple Magnetic Resonance Modalities
The purpose of this study is to determine whether dynamic contrast enhanced MRI (DCE MRI) and high diffusion weighting MRI may be used to distinguish between favorable and unfavorable responses to therapy of glioblastoma multiforme. Imaging data will be correlated with histopathologic findings and clinical responses to radiation therapy with or without chemotherapy.

Effect of Radiation Therapy Plus Temozolomide Combined With Cilengitide or Cetuximab on the 1-year Overall Survival of Patients With Newly Diagnosed MGMT-promoter Unmethylated Glioblastoma
The investigators propose to conduct a multicenter, open-label, randomized, phase II study in patients with newly diagnosed glioblastoma (CeCil). Patients should meet all eligibility criteria for the CENTRIC phase III trial at the exception that no MGMT-promoter methylation could be demonstrated. The treatment backbone in both study arms will consist of postoperative radiation therapy with concomitant daily temozolomide, followed by 6 cycles of temozolomide according to a 21 out of 28 days regimen (as in the experimental arm of the RTOG 0525 / EORTC 26052-22053 phase III study). In study arm (A) Cilengitide (at a dose of 2000 mg by iv administration, 2x/week) will be added to...

Efficacy and Safety of AP 12009 in Patients With Recurrent or Refractory Anaplastic Astrocytoma or Secondary Glioblastoma
In this multinational Phase III study the efficacy and safety of 10 µM AP 12009 is compared to standard chemotherapy (temozolomide or BCNU or CCNU) in adult patients with confirmed recurrent or refractory anaplastic astrocytoma (WHO grade III) or secondary glioblastoma (WHO grade IV).

Efficacy and Safety of Imatinib Mesylate Plus Hydroxyurea (HU) in Patients With Recurrent Glioblastoma Multiforme (GBM)
This was an investigational study to assess the objective overall response (OOR) rate (complete response [CR] + partial response [PR]) of imatinib mesylate and hydroxyurea (hydroxycarbamide) combination therapy in patients with recurrent glioblastoma multiforme (brain tumors). This study also evaluated the duration of tumor response (as per MacDonald criteria), clinical benefit, progression-free survival rate at 6 and 12 months, and the survival rate at 12 and 24 months.

Efficacy of Hypofractionated XRT w/Bev. + Temozolomide for Recurrent Gliomas
This phase II trial studies how well giving hypofractionated radiation therapy together with temozolomide and bevacizumab works in treating patients with high-grade glioblastoma multiforme or anaplastic glioma. Specialized radiation therapy, such as hypofractionated radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the...
