Active clinical trials for "Glioma"

RATIONALE: Studying samples of blood in the laboratory from patients receiving temozolomide may help doctors learn how temozolomide works in the body. It may also help doctors learn more about how a patient's genes may affect the risk of developing thrombocytopenia. PURPOSE: This clinical trial is studying the pharmacokinetics in patients with newly diagnosed high-grade glioma receiving temozolomide and radiation therapy.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I/II trial to study the effectiveness of carmustine followed by surgery in treating patients who have recurrent supratentorial malignant glioma or metastatic brain neoplasm.

Glioma is the most common primary malignant Brain Tumor. Although the traditional treatment (surgery, radiotherapy and chemotherapy) has been actively carried out, the curative effect of High grade glioma (HGG) is still poor.On the basis of a lot of exploration, the union medication has become a hot spot. Malignant glioma has obvious neovascularization and inhibiting angiogenesis can inhibit tumor proliferation and invasion.Studies have found that inhibiting VEGFR-2 can can reduce neovascularization and inhibit tumor growth. NCCN clinical practice guidelines recommend bevacizumab(BEV) for the treatment of recurrent malignant gliomas. AVAglio＆RTOG 0825 subgroup analysis showed that TMZ combined with antiangiogenic drugs may have advantages in the first-line treatment of patients with IDH1 wild-type high grade glioma.However, some studies have shown that bevacizumab can lead to rapid deterioration due to hypoxia or phenotypic changes. So it is urgent to find new antiangiogenic drugs. Apatinib is an oral small molecule antiangiogenic targeted drug. Apatinib plus temozolomide has been shown to be effective and tolerable in recurrent glioma. So the investigators aimed to evaluate the efficacy and safety of temozolomide combined with apatinib in the new diagnosis of high-grade glioma，and to explore the new first-line treatment of HGG, especially to TMZ insensitivity patients(MGMT gene promoter unmethylated) and poor prognosis (IDH1 wild type) population. And Find out the benefit groups of the two drugs.

The aim of the study was to explore the dose-limiting toxicity (DLT) and the maximum tolerable dose (MTD) of oral administration of TG02 capsules twice a week for 4 weeks.

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.

This trial is aimed at evaluating the safety and effectiveness of PCV chemotherapy in patients with recurrent high-grade glioma with IDH1/2 mutation.

The purpose of this study is to look at how a chemotherapy treatment (Temozolomide, also called Temodar) affects the process of ovarian aging which is measured by a decline in ovarian follicle count, in patients with Low Grade Glioma (LGG). It is important to know if different patient factors and Temozolomide influence the rate of ovarian aging in women with LGG who have good long-term survival rates. This will allow better counseling about the effects of this particular chemotherapy agent on fertility in women.

Gliomas are the most common primary brain tumor, yet remain a challenge to effectively treat. Mounting evidence suggests that survival improves with greater tumor removal, yet being able do a complete removal can be difficult due to the tumor's infiltrating nature. 5-aminolevulinic acid (5-ALA) is a natural compound that, when patients take it by mouth 3 hours before surgery, is selectively taken up by glioma cells and causes a red/pink fluorescence (glow) under a blue light that allows tumor margins to be seen during the course of surgery. While this compound is used as a standard-of-care agent in Europe, it remains under testing by the Food and Drug Administration (FDA). A recent clinical trial in Germany, however, has demonstrated a significant improvement in the rate of complete resection for certain brain tumors (65% vs. 34%). The Barrow 5-ALA Intraoperative Confocal (BALANCE) Trial will measure the effect of 5-ALA on the amount of glioma tumor removal. To improve the usefulness of 5-ALA, a new special microscope fitted with a blue light, will be used to magnify microscopic fluorescence at the tumor margins. The investigators' hypothesis is that 5-ALA fluorescence with the use of the special microscope during surgery will greatly lower the amount of tumor left behind.

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).

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Tamoxifen may kill tumor cells by blocking the enzymes necessary for cell growth. Combining radiation therapy with tamoxifen may be effective in treating newly diagnosed brain stem glioma. PURPOSE: Phase II trial to study the effectiveness of combining radiation therapy and tamoxifen in treating children who have newly diagnosed brain stem glioma.
