Active clinical trials for "Glioblastoma"

This is an open-label, single-arm, non-randomized, intermediate-sized expanded access study evaluating the safety, efficacy, and tolerability of PVSRIPO delivered via intratumoral infusion, in subjects with glioblastoma (GBM) who are ineligible to participate in clinical study with PVSRIPO that is currently open to enrollment.

Radiological Markers of vascularity as wash-in rate, washout rate, and capillary time to peak in different single tumour regions were extracted for all glioblastoma patients before being surgically resected from preoperative DCE-MRI. Tissue samples were obtained from different intratumoral regions and peritumoral oedema and evaluated for the vascular endothelial growth factor (VEGF)

Measuring the bioavailability of orally administered curcumin in the tumors of glioblastoma patients.

The study is an open-label expanded access study for patients for whom vaccine was manufactured during the Northwest Biotherapeutics' 020221 DCVax-L for GBM screening process, but who subsequently failed to meet specific enrollment criteria. Patients will receive therapy per investigator discretion (standard of care) as well as active vaccine per the 020221 protocol administration schedule. It is estimated that approximately 99 patients will enroll in this study.

Glioblastoma face an increased risk of venous or arterial thromboembolism. Furthermore, the most frequent immune cells in glioblastoma are tumor associated macrophages, which find theirself in an anti-inflammatory (M2) phenotype. Increased conjugates between circulating platelets and monocytes reflect an pro-inflammatory status.

This is a pilot study to determine uptake of PET tracer 18F-PSMA-1007 in primary glioblastoma.

The goal of this study is to create a comprehensive database of Magnetic Resonance Imaging (MRI) and of pathology for patients with brain tumors. Both standard, advanced, and research MRI components may be included, these will be analyzed in comparison with pathology results if/when a biopsy is obtained, and also used to predict/evaluate responses to therapy. This study will create a database of de-identified MRI images which include these techniques so that brain tumors can be studied over time (longitudinally) in an organized manner.

This study offers evaluation of patients with brain and spinal cord tumors. Its purpose is threefold: 1) to allow physicians in NIH s Neuro-Oncology Branch to increase their knowledge of the course of central nervous system tumors and identify areas that need further research; 2) to inform participants of new studies at the National Cancer Institute and other centers as they are developed; and 3) to provide patients consultation on possible treatment options. Children (at least 1 year old) and adults with primary malignant brain and spinal cord tumors may be eligible for this study. Participants will have a medical history, physical and neurological examinations and routine blood tests. They may also undergo one or more of the following procedures: Magnetic resonance imaging (MRI) MRI is a diagnostic tool that uses a strong magnetic field and radio waves instead of X-rays to show detailed changes in brain structure and chemistry. For the procedure, the patient lies on a table in a narrow cylinder containing a magnetic field. A contrast material called gadolinium may be used (injected into a vein) to enhance the images. The procedure takes about an hour, and the patient can speak with a staff member via an intercom system at all times. Computed axial tomography (CAT or CT) CT is a specialized form of X-ray imaging that produces 3-dimensional images of the brain in sections. The scanner is a ring device that surrounds the patient and contains a moveable X-ray source. The scan takes about 30 minutes and may be done with or without the use of a contrast dye. Positron emission tomography (PET) PET is a diagnostic test that is based on differences in how cells take up and use glucose (sugar), one of the body s main fuels. The patient is given an injection of radioactive glucose. A special camera surrounding the patient detects the radiation emitted by the radioactive material and produces images that show how much glucose is being used by various tissues. Fast-growing cells, such as tumors, take up and use more glucose than normal cells do, and therefore, the scan might indicate the overall activity or aggressiveness of the tumor. The procedure takes about an hour. When all the tests are completed, the physician will discuss the results and potential treatment options with the patient. Follow-up will vary according to the individual. Some patients may end the study with just one visit to NIH, while others may be followed at NIH regularly, in conjunction with their local physicians. Patients with aggressive tumors may be seen every 3 or 4 months, while those with less active tumors may be seen every 6 to 12 months. Permission may be requested for telephone follow-up (with the patient or physician) of patients not seen regularly at NIH. ...

Glioblastomas, the most frequent malignant brain tumor in adults, are widespread in the brain, despite their discrete appearance on computed tomography (CT) or magnetic resonance imaging (MRI). While this tumor tends to spread widely in the brain, unlike other tumors of the body, it rarely metastasizes, or spreads, to other organs. Approximately 10 percent of patients with glioblastoma develop metastatic disease after radiation or brain surgery. In the absence of radiation or brain surgery, few patients have developed disease spread outside the brain. During surgery to remove tumors of other organs of the body, such as the lung, prostate, kidney, or ovary, cells from these tumors are routinely found in the bloodstream. These cells are believed to be the reason for the spread of these tumors. In the case of malignant brain tumors, this process of glioma (tumor) cells shedding into circulation has not yet been investigated. This study will determine whether glioma cells can be detected in the bloodstream of patients undergoing surgery. If glioma cells are absent, it may mean they are unable to penetrate the blood-brain barrier. If they are present, they presumably can penetrate into blood vessels but they may be recognized and eliminated by the immune system, or they may escape detection yet not be able to take hold in the new microenvironment. The results of the study will add to the knowledge of the biology of these highly malignant tumors. Study participants will be admitted to the hospital for 8 to 10 days. They will undergo a complete physical and neurological exam and blood and urine tests. An electrocardiogram will be performed, and x-rays may be taken. On the morning of surgery, the patient will receive sedation intravenously. A tiny plastic tube called a catheter will be introduced into a vein in the groin through needles. The catheter will be passed through to the jugular bulb, right above the jugular vein, on the same side as the tumor. The patient will then be taken to the operating room for surgery. During surgery, not more than one quarter of a unit of blood will be removed through the catheter. The catheter will be removed before the patient enters the intensive care unit. Another MRI will be taken after surgery. The study will enroll participants for 2 years. Patients will be followed at 3 months and 6 months after the surgery to make sure the postoperative period is uneventful.

Glioblastoma(GBM) is the most common malignant primary brain tumor and has unfortunately bad prognosis .PDL(Programmed death lignad 1)1 is alignad for a protein receptor PD1(Programmed death 1) that upon their engagement, an immunoinhibitory signal is generated thus allowing the tumor cells to evade the immune regulation and cytotoxic T lymphocytes(CTL). Also there have been many actions generated upon PDL1 binding with its receptor, among them is activation of autophagy that also serves for promoting tumor development and progression.Our study aims to detect PDL1 and LC3B levels in GBM , their relation with each other and the relation between their levels and overall survival of GBM cases.
