Active clinical trials for "Astrocytoma"

RATIONALE: Immunotoxins can locate tumor cells and kill them without harming normal cells. Immunotoxin therapy may be an effective treatment for glioblastoma multiforme and anaplastic astrocytoma. PURPOSE: Phase I trial to study the effectiveness of immunotoxin therapy in treating children who have progressive or recurrent glioblastoma multiforme or anaplastic astrocytoma

RATIONALE: New imaging procedures such as magnetic resonance imaging may improve the ability to determine the growth rate of progressive astrocytoma. PURPOSE: Phase II trial to study the effectiveness of magnetic resonance imaging in treating children who have progressive low-grade astrocytoma.

RATIONALE: IL-4(38-37)-PE38KDEL immunotoxin may locate tumor cells and kill them without harming normal cells. This may be an effective treatment for recurrent malignant astrocytoma. PURPOSE: Phase I trial to study the effectiveness of IL-4(38-37)-PE38KDEL immunotoxin in treating patients who have recurrent malignant astrocytoma.

The purpose of the study is to confirm the safety of the selected dose and potential toxicity of oncolytic poliovirus (PV) immunotherapy with PVSRIPO for pediatric patients with recurrent WHO grade III or IV malignant glioma, but evidence for efficacy will also be sought. The primary objective is to confirm the safety of the selected dose of PVSRIPO when delivered intracerebrally by convection-enhanced delivery (CED) in children with recurrent WHO Grade III malignant glioma (anaplastic astrocytoma, anaplastic oligoastrocytoma, anaplastic oligodendroglioma, anaplastic pleomorphic xanthoastrocytoma) or WHO Grade IV malignant glioma (glioblastoma, gliosarcoma). A secondary objective is to estimate overall survival (OS) in this population.

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).

The purpose of the current trial is to explore whether the standard treatment with radiotherapy and temozolomide affect the tumor vasculature in patients with high-grade astrocytomas. If vascular effects are identified, future clinical trials can be proposed wherein anti-angiogenic agents are added to increase patient survival.

This study is being conducted to help determine whether the addition of Interferon-alpha(α-IFN),which were determined sensitized the activity of Temozolomide(TMZ) in vivo and vitro, when given along with temozolomide during the monthly cycles that follow radiation, is able to delay tumor growth, shrink tumors, or impact how long people with newly diagnosed high-grade glioma.

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.

This is a phase III, non-blinded, blocked randomized clinical trial. The study is conducted on 62 newly diagnosed patients with brain glioblastoma multiforme and anaplastic astrocytoma referring to the oncology clinics during March 2018 and March 2019. The patients will be randomized to 6-cycle and 12-cycle adjuvant Temozolomide groups using block randomization method (1:1).

This study is being conducted to help determine whether β-elemene as maintain treatment for complete remission patients of newly diagnosed malignant gliomas following standard treatment, is able to delay tumor growth, or impact how long people with newly diagnosed high-grade glioma.
