Filter by:This phase I study evaluated a Gene Mediated Cytotoxic Immunotherapy approach for malignant gliomas, including glioblastoma multiforme and anaplastic astrocytoma. The purpose of this study was to assess the safety and feasibility of delivering an experimental approach called GliAtak which uses AdV-tk, an adenoviral vector containing the Herpes Simplex thymidine kinase gene, plus an oral anti-herpetic prodrug, valacyclovir, in combination with standard of care radiation.
This is a Phase I study of Nanoliposomal CPT-11 in patients with Recurrent high-grade gliomas. Patients must have a histologically proven intracranial malignant glioma, which includes glioblastoma multiforme (GBM), gliosarcoma (GS), anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), anaplastic mixed oligoastrocytoma (AMO), or malignant astrocytoma NOS (not otherwise specified). Patients who are wild type or heterozygous for the UGT1A1*28 gene will received Nanoliposomal CPT-11. The total anticipated accrual will be approximately 36 patients (depending upon the actual MTD). The investigators hypothesis is that this new formulation of CPT-11 will increase survival over that seen in historical controls who have recurrent gliomas because CPT-11 will be encapsulated in a liposome nanoparticle, which has been seen to reduce toxicities from the drug.
The purpose of this surveillance is to evaluate the postmarketing safety and efficacy of Temodal capsule (temozolomide) under actual conditions of use, and to understand some of the following points that are in question and doubt: - Incidence of adverse events under actual conditions of use (Serious and Nonserious Adverse Events); - Adverse Drug Reactions not shown in the directions for use (will be stated as Unexpected Adverse Reaction); - Adverse Event caused by misuse, abuse, or drug interactions; - Other information concerned with safety or efficacy.
Background: The optimal treatment of anaplastic gliomas is controversial. Standard of care in most centers is still radiotherapy. This phase III study compared the efficacy and safety of radiotherapy vs chemotherapy in patients (pts) with newly-diagnosed, supratentorial gliomas of WHO grade III. Methods: Pts were randomized 2:1:1 between June 1999 and February 2005 in 34 German centers to receive (i) a 6-week course of radiotherapy (1,8-2 Gy fractions, total dose 54-60 Gy) or (ii) four 6-week cycles of CCNU at 110 mg mg/m2 on day 1, vincristine at 2 mg on days 8 and 29 and procarbazine at 60 mg/m2 on days 8-21 or eight 4-week cycles of 200 mg/m2 temozolomide on days 1-5. Treatment was stopped prematurely at disease progression or occurrence of unacceptable toxicity. At this time or at disease progression, treatment in the radiotherapy group was continued with one of the chemotherapies (1:1 randomization) and with radiotherapy in both chemotherapy groups. The primary endpoint was time-to-treatment-failure (TTF) defined as progression after radiotherapy and one chemotherapy in either sequence, or any time before if further therapy could not be employed. Assuming a 50% improvement in TTF of starting with chemotherapy, 318 pts were to be enrolled to provide 80% power to achieve statistical significance at a one-sided level of 0.05.
The purpose of this study is to confirm the safety and efficacy of temozolomide in patients with newly diagnosed malignant glioma (concomitant with radiotherapy and then as monotherapy) and relapsed malignant glioma (as monotherapy) when used in the daily medical practices. Post-marketing surveys are not considered applicable clinical trials and thus the results of this survey will not be posted at its conclusion. The results will be submitted to public health officials as required by applicable national and international laws.
This phase II trial studies how well cilengitide works in treating younger patients with recurrent or progressive high-grade glioma that has not responded to standard therapy. Cilengitide may stop the growth of tumor cells by blocking blood flow to the tumor.
Background: In order to survive, brain tumors must have a network of blood vessels to supply it with oxygen and nutrients. The tumors produce substances that enable new blood vessels to form. Tandutinib and Bevacizumab are experimental drugs that may prevent new blood vessel formation and thereby slow or stop tumor growth in the brain. Objectives: To determine the safety and side effects of Tandutinib in combination with Bevacizumab in patients with brain tumors. To evaluate the response of brain tumors to treatment with Tandutinib and Bevacizumab. Eligibility: Patients 18 years of age and older with a malignant brain tumor for whom standard treatments (surgery, radiation and chemotherapy) are no longer effective. Design: Patients receive treatment in 4-week cycles as follows: Tandutinib by mouth twice a day every day and intravenous (through a vein) infusions of Bevacizumab over 90 minutes (or less if well tolerated) every 2 weeks. Treatment may continue for up to 1 year, and possibly longer, as long as there are no signs of tumor growth or serious treatment side effects. Patients are evaluated with magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET) scans before starting treatment and then periodically to determine the response to treatment. Patients have physical and neurological examinations every 4 weeks and blood tests every 2 weeks. They complete quality of life questionnaires every 4 weeks.
This phase I trial is studying the side effects and best dose of aflibercept when given together with radiation therapy and temozolomide in treating patients with newly diagnosed or recurrent glioblastoma multiforme, gliosarcoma, or other malignant glioma. Aflibercept may stop the growth of tumor cells by blocking blood flow to the tumor. Radiation therapy uses high-energy x-rays to kill tumor cells. 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. Giving aflibercept together with radiation therapy and temozolomide may kill more tumor cells.
18F-Fluorothymidine is a recently developed PET tracer to image tumor cell proliferation. Very few data report an interest of using such a tracer for cerebral malignant tumor management. In our project, we want to compare the tumoral volumes obtained with PET and MRI, with the gold standard histopathological diagnosis according to the WHO grading malignancy scale and the Ki-67 proliferation index, for preoperative evaluation as much as for tumoral postoperative residue evaluation. Furthermore, we want to explore the interest of 18F-FLT-PET volume to better delineate tumoral volume in radiotherapeutic management of gliomas.
