Active clinical trials for "Glioma"

This study is designed to assess the safety and feasibility of using the ExAblate, Type 2 to temporarily disrupt the blood brain barrier in non-enhancing suspected infiltrating glioma. The ExAblate Model 4000 Type-2 is intended for use as a tool to disrupt the BBB.

This phase I/II trial studies the side effects and how well BGB-290 and temozolomide work in treating patients with gliomas (brain tumors) with IDH1/2 mutations that have come back. BGB-290 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving BGB-290 and temozolomide may work better in treating patients with recurrent gliomas.

This single center, single arm, open-label, phase I study will assess the safety of a laparoscopically harvested omental free flap into the resection cavity of recurrent glioblastoma multiforme (GBM) patients. All participants included in the study will undergo standard surgical resection for diagnosed recurrent GBM. Following the resection, the surgical cavity will be lined with a laparoscopically harvested omental free flap. The participant's dura, bone and scalp will be closed as is customary. The participant will be followed for side effects within 72 hours, 7 days, 30 days, 90 days and 180 days. Risk assessment will include seizure, stroke, infection, tumor progression, and death.

Compare the data obtained from the Raman analyzer and paraffin pathology examination on the same external brain tissue sample. Evaluate the effectiveness and safety of the Raman analyzer for intraoperative diagnosis gliomas of brain resection tissue samples, using paraffin pathological examination results as clinical reference standards.

The goal of this multi-center clinical trial is to evaluate the effectiveness of MRI-based computer-aided diagnosis software (V1) for glioma segmentation, gene prediction, and tumor grading. Machine learning methods such as high-precision tumor segmentation and classification and discrimination modeling can further optimize the non-invasive molecular diagnosis and prognosis prediction. The main question it aims to answer is whether the software can predict the molecular type and the prognosis quickly and correctly. The results will be compared with the real-world clinical data double-blindly. Finally, form a set of user-friendly automatic glioma diagnosis and treatment systems for clinics.

HGG comprises diffuse midline gliomas (DMG), including diffuse infiltrating brainstem glioma (DIPG), characterised by histone gene mutations, as well as non-DM HGGs mainly in non-midline supratentorial areas, with distinct molecular abnormalities. First-line treatment comprises surgery when doable (non-DM HGGs), and radiotherapy in all cases. Chemotherapy or other drugs in clinical trials may be added during and/or after radiotherapy depending on the HGG subtype. The recurrence rate is nevertheless high in all paediatric and adolescent HGGs. If the time interval between the end of first-line radiotherapy and relapse is long enough, re-irradiation often provides good palliation of symptoms, delays disease progression, improves quality of life and has minimal and manageable toxicity. Nevertheless, strategies to increase efficacy without increasing toxicity in the treatment of recurrent paediatric HGG are much needed. AsiDNA™ is a DNA repair inhibitor that increases the vulnerability of tumour cells to irradiation without increasing toxicity in healthy tissues. Its novel mechanism of action, based on perturbation of the DNA damage recognition steps in DNA repair, makes its activity specific to tumour cells. Intravenous administration of AsiDNA is currently being investigated in adults with advanced solid tumours. The MTD was not reached during the escalating dose study on the safety, pharmacokinetics and pharmacodynamics of AsiDNA administered as a 1-hour infusion, however an optimal dose range (400-600 mg) was identified for further development, based on the favourable safety and PK profiles. Preclinical studies on AsiDNA added to radiotherapy have shown increased survival and no increase in short- or long-term toxicity due to the high doses of irradiation. The study will provide paediatric patients who have recurrent HGG with early access to innovation, even during the early drug development stage in adults.

The purpose of this study is to evaluate the safety and effectiveness of using the Exablate Type 2 system using microbubble resonators (Exablate Test Arm) to disrupt the Blood-Brain Barrier for the purpose of temporarily transforming, and thereby 'marking', regions of infiltrating gliomas prior to planned surgical resection, for the purpose of improving tumor visualization during the surgery to achieve a greater proportion of subjects who receive a Gross Total Resection (GTR) per plan compared to those not undergoing a BBBD procedure prior to resection (Control Arm).

Current therapies for diffuse, intrinsic pontine glioma (DIPG) provide very limited benefit to the patient. The rationale for the use of Antineoplaston therapy in this protocol study derives from experience with subjects from prior Phase 2 studies and Compassionate Exemption patients treated with Antineoplaston therapy at the Burzynski Clinic. This study is designed to analyze the efficacy and safety of Antineoplaston therapy in five separate DIPG patient cohorts, which are defined by age and prior therapy. This is a two stage study with 20 patients in each cohort being enrolled in the first stage and an additional 20 patients being enrolled in the second stage, if pre-determined efficacy endpoints in the first stage are realized.

A study is being performed to observe whether a novel type of brain imaging using a technique called PET-MRI may provide useful information in the 'mapping' of adult primary brain tumours. It employs a radiolabelled molecule targeting a particular molecule called PSMA which is hypothesised to be a marker of aggression in primary brain tumours. 'Mapping' of the concentration and distribution of this molecule within brain tumours via PET-MRI may provide vital clinical information regarding the extent and timing of treatment.

The purpose of this study is to see if 18F-Fluciclovine (Axumin®) is useful and safe in the management of children with Low Grade Gliomas (LGG). Imaging with 18F-Fluciclovine PET-MRI will be performed prior to initiation of therapy for LGG, and then 3 months, and 1 year after starting therapy. Changes in 18F-Fluciclovine uptake will be compared to changes in MRI measurements at 3 months and 1 year as compared to baseline.
