Active clinical trials for "Glioma"

The purpose of this study is to investigate the correlation of SV2A expression in surgically removed tumour and tumour-surrounding tissue of glioma patients suffering from epilepsy with their clinical response to levetiracetam.

A Prospective Exploratory Clinical Study to explore the efficacy of Hospital Traditional Chinese Medicine Preparation Kangliuwan for Recurrent Grade IV Glioma.

establishment of glioma microenvironment cell dynamic evolution database reveal the mechanism of GIM promoting malignant transformation of glioma cells reveal the dynamic regulation process of immune cells in the process of glioma evolution

Targeted therapy with bevacizumab is the main method to prolong the progression-free survival of patients with recurrent malignant gliomas in recent years. Using noninvasive imaging methods to predict which RMG may respond to bevacizumab regimen therapy is a clinical problem ; on the other hand, repeated gadolinium enhancement may increase the risk of gadolinium ion deposition of brain tissue. Furthermore,there may be a false response phenomenon and cause assessment bias.in the evaluation of treatment efficacy,owing to bevacizumab is only anti-tumor angiogenesis. Amide Proton Transfer (APT) is a new molecular imaging technique. Our previous studies have shown that imaging features and signal changes of APT can fully reflect the therapeutic effect of malignant glioma,without the injection of contrast agent and avoid the side effects. RMG patients will be recruited in this study . This project will be designed multi-center, prospective, observational clinical research. The changes of APT signal intensity before and after treatment will be compared with those of different types of RMG line. The relationship between APT imaging characteristics and clinical end point events will be investigated and compared with conventional MR imaging technique. The sensitivity, specificity and accuracy of the progression-free survival and median overall survival will be measured after treatment with bevacizumab.

RATIONALE: Studying samples of tumor tissue and blood in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors understand why low-grade gliomas develop in young patients and predict how they will respond to treatment. PURPOSE: This clinical trial is studying tumor tissue, blood samples, and family history in predicting tumor development and response to treatment in young patients with low-grade glioma.

Tectal plate gliomas are relatively rare tumors of childhood with a reported incidence of 10%. Their typical clinical presentation is symptoms and signs of hydrocephalus and are often incidentally diagnosed in the imaging work-up of children with hydrocephalus. Tectal tumors in children comprise a subcategory of brainstem tumors with unique clinical, imaging, and spectroscopic features. There is debate whether they truly represent brainstem tumors or whether they are a site of benign cellular overgrowth. The majority of these tumors are pathologically benign and show no or minimal growth. Not all tectal plate tumors, however, have this typically benign course. Some can manifest a more aggressive behavior. There have been reports in the past attempting to analyze the histology and behavior of these tumors. None of the prior series looking at these tumors have included Magnetic Resonance Spectroscopy (MRS) analysis. It is interesting that according to where tumors occur in the brainstem usually indicates what their histology and behavior is. Although not absolute, we know that tumors can have a very poor prognosis versus an extremely good prognosis depending on their location in the brainstem. Yet there are always the cases that do not act in the typical fashion and this is where MRS can prove helpful. This study is being done to look at a region of the brain, called the tectal plate, in children. This part of the brain can be involved by tumors. Because of the location of the tectal plate, it is usually very difficult and risky to get a biopsy (tissue sample) from this area. Magnetic Resonance Spectroscopy (MRS) is a non-invasive imaging technique that can look at the chemical make up of the brain. MRS may allow us to better understand the nature and behavior of these tumors. However, in order to understand disease in this area, we need to look at the normal chemical make up of the brain in children without tectal plate tumors. Healthy patients are being asked to participate as a normal volunteer. We anticipate having a total of 10 to 12 normal volunteers in the MRS study.

This is an intermediate-size expanded access protocol to provide ONC201 to patients with diffuse intrinsic pontine gliomas who cannot access ONC201 through clinical trials.

This is an expanded access program (EAP) for patient with Melanoma and Glioblastoma who have progressed after prior Protocol therapy including Bevacizumab, Temozolomide ( TMZ ), Ipilimumab, BRAF and MEK inhibitors. The patients whose tumors are EGFR, MET or ALK positive should first receive an EFGR or ALK inhibitor, respectively, prior to treatment with pembrolizumab.

The objective of this expanded access program is to provide ONC201 to eligible patients with previously-treated glioma that exhibits the H3 K27M mutation and/or that is located in the midline region of the brain.

The treatment of patients with World Health Organization (WHO) grade 4 malignant glioma has not seen any significant breakthrough the past years. Following surgery and radio / chemotherapy patients still experience a very high recurrence risk and the prognosis is dismal. The investigators observed patients with grade IV malignant glioma receiving individualized treatment based on their molecular profile including fully personalized vaccines.
