Filter by:The purpose of the Dendritic Cell Immunotherapy study for patients with glioblastoma and/or brainstem glioma is to determine whether in patients with malignant brain tumors, dendritic cells injected peripherally can reactivate the immune system against the brain tumor.
This research is being determine whether vaccinations with your own immune cells called " dendritic cells " can activate your immune system to fight your brain tumor.
The purpose of this study is to evaluate the efficacy of temozolomide on a protracted schedule, after standard 5-day temozolomide regimen in patients with recurrent or progressive high grade glioma.
To determine whether a mild ketogenic diet can influences quality of life and survival of patients with recurrent glioblastoma
RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking some of the blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving everolimus together with temozolomide and radiation therapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with temozolomide and radiation therapy in treating patients with newly diagnosed glioblastoma.
The mechanism of action of sorafenib makes it an interesting drug to investigate in the treatment of patients with glioblastoma multiforme. Efficacy of agents with anti-angiogenic activity has already been demonstrated and the PDGF receptor target may also be pertinent in glioblastoma. The combination of temozolomide plus sorafenib has been investigated previously in the treatment of patients with advanced melanoma. The combination was generally well tolerated; in previously untreated patients, a standard dose of sorafenib (400mg PO bid) was administered with temozolomide 150mg/m2 PO daily for 5 days, repeated every 28 days (23). In this multicenter phase II study, patients with newly diagnosed glioblastoma will receive standard treatment, including initial debulking surgical resection (if feasible) followed by high-dose radiation therapy with concurrent temozolomide. After completion of radiation therapy, patients will continue treatment with temozolomide (150mg/m2 days 1-5) and sorafenib (400mg PO bid daily), repeated at 28-day intervals for 6 cycles.
This phase II trial is studying how well gossypol works in treating patients with progressive or recurrent glioblastoma multiforme. Gossypol may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Malignant gliomas, which include Glioblastoma multiforme (GBM), are the most common and most aggressive types of brain cancer, accounting for approximately 60% of primary brain tumors. These tumors are characterized by diverse molecular abnormalities (within the same tumor), which, along with the difficulties of many standard chemotherapies crossing the blood barrier, contribute to the very poor response to therapy and poor survival. We recently showed that Dichloroacetate (DCA, an inhibitor of the mitochondrial pyruvate dehydrogenase kinase) was able to depolarize cancer (but not normal) mitochondria and induce apoptosis in cancer but not normal tissues. We believe that altering the metabolism of cancers like glioblastoma (DCA switches metabolism from the cytoplasmic glycolysis to the mitochondrial glucose oxidation) we inhibit the resistance to apoptosis that characterizes cancer. Because metabolism (i.e. glycolysis) is the end result of many and diverse molecular pathways, the effects of DCA might be positive in cancers with diverse molecular backgrounds. DCA is also a very small molecule that readily crosses the blood brain barrier. Therefore we hypothesize that DCA will be an effective and relative non-toxic potential therapy for malignant gliomas. We are conducting a phase II trial with 2 parallel arms: a) patients with newly diagnosed malignant gliomas and b) patients with recurrent gliomas or gliomas that have failed standard therapy (which includes surgery, radiotherapy and chemotherapy). All patients need to have a histological diagnosis. DCA will be given orally and patients will be followed for a minimum of 6 months. The tumor size will be followed by standard MRI or CT criteria and glucose uptake (a direct effect of DCA on the tumor) will be measured by FDG-PET imaging. Several clinical parameters and quality of life will be followed. Potential toxicity (particularly peripheral neuropathy) will be closely followed and dose-de-escalation protocols are in place in case of toxicity. In addition, escape protocols for the application of standard therapy (when appropriate) are in place in patients with no evidence of response to DCA. In vitro studies will be performed in the tissues obtained at the time of surgery (where appropriate) and correlated prospectively with clinical data. There is limited ability to accept patients outside of Alberta; this is in part because the visit and testing schedule is intense, requiring residence in Edmonton for at least 6 months.
This is a phase II study of Bevacizumab plus Temodar and Tarceva in patients with non-progressive glioblastoma or gliosarcoma. Patients must have stable disease immediately following a standard course of up-front radiotherapy and Temodar. All patients will receive Bevacizumab, Temodar and Tarceva. A total of 60 patients will be enrolled. Our hypothesis is that the combination of Bevacizumab plus Temodar and Tarceva will increase survival over that seen in historical controls who have newly diagnosed, non-progressive glioblastoma or gliosarcoma following radiotherapy plus Temodar and use Temodar alone.
The purpose of the protocol was to induce a novel radiochemotherapy with enzastaurin as first-line treatment regimen in glioblastoma: Participants with active, unmethylated MGMT promoter were treated with enzastaurin before, concomitant, and after radiotherapy to determine safety and PFS at 6 months (PFS-6) in phase II.
