View clinical trials related to Glioblastoma.
Filter by:Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. The treatment comprises maximal safe resection followed by radiotherapy and chemotherapy. Despite appropriate management, 90% of the patients will develop relapse or progression. After progression, the median survival is 5.2 months (Stupp, 2009). The treatment of GBM relapse remains investigational. Reirradiation is an option in selected cases. The objective of this study is to compare 2 schemes of stereotactic hypofractionated radiotherapy in the management of recurrent GBM.
This phase I trial studies the side effects and best dose of combination chemotherapy in treating patients with glioblastoma multiforme after radiation therapy. Drugs used in chemotherapy, such as temozolomide, memantine hydrochloride, and metformin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing them or stopping them from dividing. Mefloquine may help temozolomide, memantine hydrochloride, and metformin hydrochloride kill more cancer cells by making tumor cells more sensitive to the drug. Giving more than one drug (combination chemotherapy) may kill more tumor cells.
The purpose of this access protocol is to allow patients with brain tumors who had previously received 125I-MAB 425 to receive additional course(s) of 125I-MAB 425 until their brain tumor begins to grow, they develop side effects to the treatment, or their medical condition changes (e.g., you become pregnant, become infected with human immunodeficiency virus (HIV) or develop another cancer).
Indication: Subjects with glioblastoma at first relapse after surgery, radiotherapy and first-line temozolomide (TMZ). Objectives: 1. Phase I endpoint: - To determine the maximum tolerated dose (MTD) of CPT-11 administered on days 8 and 22 in combination with a fixed, continuous, and metronomic regimen of TMZ, given in 28-day cycles. 2. Phase II endpoints: Primary endpoint: Progression-free survival at 6 months. Secondary endpoints: Response rate, toxicity profile, overall survival. Complementary studies: To assess the effect of treatment on plasma concentration of thrombospondin-1 (TSP1), soluble VEGF receptor 1 (sVEGF-1) and VEGF-A, and their correlation with clinical outcome. - To assess the correlation between immunohistochemical expression of PTEN and MGMT proteins, and clinical outcomes.
Primary Objectives Cohort A ‐‐ monotherapy: To determine the efficacy of AMG 386 in participants with recurrent glioblastoma (GBM) as measured by 6‐month progression‐free survival (PFS6) Cohort B - combination therapy: Phase I To determine the maximum tolerated dose of AMG 386 in combination with bevacizumab given at 10mg/kg every 2 weeks in participants with recurrent glioblastoma. Phase II To determine the efficacy of AMG 386 plus bevacizumab in participants with recurrent glioblastoma (GBM) as measured by 6‐month progression‐free survival (PFS6). Secondary Objectives: To evaluate radiographic response in both cohort populations. To evaluate overall survival in both cohort populations. To assess time‐to‐progression in both cohort populations. To investigate the safety profile in both cohort populations. Exploratory Objectives: To evaluate expression of factors associated with tumor angiogenesis using a multiples cytokine assay among participants undergoing therapy with AMG 386 with response to therapy and development of resistance. This is an open‐label Phase I/II study of AMG 386 monotherapy and AMG 386 in combination with bevacizumab. Two cohorts will accrue and will be assessed sequentially. Each cohort will enroll participants with recurrent GBM. Cohort A will assess recurrent GBM participants who receive AMG 386 monotherapy at 30 g/kg every week. (Cohort A initially accrued at a dose of 15mg/kg, but this was increased to 30 mg/kg every week following an amendment). Cohort B will assess recurrent GBM participants who receive weekly AMG 386 plus bi‐weekly bevacizumab (10mg/kg). Cohort B will start with a Phase I component to determine the MTD of AMG 386 that is safe when used in combination with bevacizumab. AMG 386 is administered intravenously, and, when used in combination with intravenous bevacizumab, will be administered first. Patients will be required to come to the clinic weekly for study drug administration. For study purposes, a cycle of therapy will be 4 weeks. Treatment will continue until either evidence of progressive disease, unacceptable toxicity, non‐compliance with study follow‐up, or withdrawal of consent. The estimated rate of accrual is 60 participants per year. The estimated date of accrual completion is 1.5 years from study initiation. The estimated date of study completion will be approximately 12 months from enrollment of the last study participant.
The main purpose of this study is to evaluate the most effective immunotherapy vaccine components in patients with malignant glioma. Teh investigators previous phase I study (IRB #03-04-053) already confirmed that this vaccine procedure is safe in patients with malignant brain tumors, and with an indication of extended survival in several patients. However, the previous trial design did not allow us to test which formulation of the vaccine was the most effective. This phase II study will attempt to dissect out which components are most effective together. Dendritic cells (DC) (cells which "present" or "show" cell identifiers to the immune system) isolated from the subject's own blood will be treated with tumor-cell lysate isolated from tumor tissue taken from the same subject during surgery. This pulsing (combining) of antigen-presenting and tumor lysate will be done to try to stimulate the immune system to recognize and destroy the patient's intracranial brain tumor. These pulsed DCs will then be injected back into the patient intradermally as a vaccine. The investigators will also utilize adjuvant imiquimod or poly ICLC (interstitial Cajal-like cell) in some treatment cohorts. It is thought that the host immune system might be taught to "recognize" the malignant brain tumor cells as "foreign" to the body by effectively presenting unique tumor antigens to the host immune cells (T-cells) in vivo.
RATIONALE: New imaging procedures, such as fluorine F 18 fluorodopa-labeled PET scan, may help in guiding surgery and radiation therapy and allow doctors to plan better treatment. PURPOSE: This clinical trial studies fluorine F 18 fluorodopa-labeled PET scan in planning surgery and radiation therapy in treating patients with newly diagnosed high- or low-grade malignant glioma
The primary objective of this study is to determine the 6-month Progression free survival (PFS) when intravenous (IV) AR-67 is administered in adults with confirmed recurrence of GBM who have not recently (> 90 days) recurred after treatment bevacizumab (including patients who've received temazolamide, but no bevacizumab). The primary objective in the rapid bevacizumab failure group (< 90 days) is to determine the 2-month PFS.
This phase II trial is studying how well gamma-secretase/Notch signalling pathway inhibitor RO4929097 works in treating patients with recurrent or progressive glioblastoma. Gamma-secretase/Notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to determine the safety, tolerability, and the maximum tolerated dose/recommended phase II dose of carboxyamidotriazole orotate (CTO) as a single agent in patients with advanced or metastatic solid tumors; in combination with oral Temodar® in patients with glioblastoma or other recurrent malignant gliomas; or in combination with oral Temodar® and radiation therapy in patients with newly diagnosed glioblastoma or other malignant gliomas.
