Active clinical trials for "Glioblastoma"

RATIONALE: New imaging procedures, such as fluorine F 18 fluorodopa-labeled PET scan, may help in guiding surgery and radiation therapy and allow doctors to plan better treatment. PURPOSE: This clinical trial studies fluorine F 18 fluorodopa-labeled PET scan in planning surgery and radiation therapy in treating patients with newly diagnosed high- or low-grade malignant glioma

This phase I trial studies how well [18F]DASA-23 and positron emission tomography (PET) scan work in evaluating pyruvate kinase M2 (PKM2) expression in patients with intracranial tumors or recurrent glioblastoma and healthy volunteers. PKM2 regulates brain tumor metabolism, a key factor in glioblastoma growth. [18F]DASA-23 is a radioactive substance with the ability to monitor PKM2 activity. A PET scan is a procedure in which a small amount of a radioactive substance, such as [18F]DASA-23, is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the substance is used. Tumor cells usually pick up more of these radioactive substances, allowing them to be found. Giving [18F]DASA-23 with a PET scan may help doctors evaluate PKM2 expression in healthy volunteers and in participants with intracranial tumors or recurrent glioblastoma.

Rationale: This project elaborates on a novel finding of the investigators that has not yet been reported in literature, namely the presence of elevated levels of atypical B cells in participants with glioblastoma. ln the period 2015 2018 the investigators analysed the blood immune subset composition of a cohort of 180 participants undergoing neurosurgery. The most relevant finding was the presence of an abnormally elevated level of B cells in the blood of the great majority of participants with glioblastoma. These B cells may be involved in the immunosuppression associated with glioblastoma that makes this tumor refractory to immunotherapy. Multiple regression analysis indicated that the increase in the frequency of atypical B cells in participants' peripheral blood was related with the administration of dexamethasone prior to surgery. However, this study design did not allow the investigators to address the causality of the relationship between dexamethasone and atypic B cell dysregulation. Alternative treatments to dexamethasone exist. Objective: To investigate the effect of dexamethasone in the dysregulation of atypic B cells in participants with glioblastoma. Study design: Observational case control pilot study with 20 participants (10 per group). Study population: Newly diagnosed participants with glioblastoma. Intervention (if applicable): Observational study. Main study parameters/endpoints: Changes in the immune subset composition and functionality in the peripheral blood of participants with glioblastoma upon administration of dexamethasone for neurological signs of peritumoral edema (oral dexamethasone). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The investigators will collect blood (28 ml) during the first visit and again (28 ml) at the time of surgery (2 weeks ± 3 days). There will not be additional site visits, physical examinations or any other tests, questionnaires. Blood collection is only a minor discomfort and it does not represent any additional risk.

The purpose of this study is to test WSD0628 in combination with radiation therapy for recurrent brain tumors.

Diffuse gliomas are common tumors involving the brain. They are usually treated by surgery followed by radiation and chemotherapy. Radiotherapy is used for the treatment of brain tumors which causes damage to the tumor cells. However, radiotherapy can also affect the surrounding healthy cells in the brain, causing inflammation and swelling in the region, which is known as radio necrosis (RN). This is considered a late side effect of radiation and is seen in 10-25% of patients treated with radiation for brain tumors. Sometimes, radionecrosis can be detected on routine imaging during follow-up without new symptoms (asymptomaticRN). At the same time, in some patients, it can give rise to new symptoms like headaches, weakness, seizures,etc (symptomatic RN). The standard treatment of RN includes steroid medicines called dexamethasone, which is helpful in a proportion of patients. This is a prospective phase 2 study. This study is being conducted to investigate the ability of the drug Chlorophyllin in the treatment of radionecrosis. Chlorophyllin is a water-soluble compound obtained from the green plant pigment called chlorophyll. It has been shown to have anti-cancer, anti-bacterial, anti-viral, anti-inflammatory, and antioxidant properties. It is also used as an oral formulation and is an over-the-counter drug in various countries, and also as a food colouring agent. This is the first time chlorophyllin will be used in the setting of brain radionecrosis. Our primary aim of the study is to assess whether CHL will improve the clinical-radiological response rates. This study will be conducted on a population of 118 patients for a duration of 3 months. The total study duration is 2 years. The study is funded by Bhabha Atomic Research Centre (BARC).

This clinical study to evaluate sonobiopsy is significant because sonobiopsy will fundamentally enhance the clinician's insight into the molecular features of an intracranial lesion to tailor treatment approaches and optimize outcomes. In addition to the standard diagnostics of anatomic imaging and surgical histology, sonobiopsy has the potential to become the third pillar for brain tumor management by radically advancing the ability to easily and regularly acquire tumor genetic and molecular signatures. This enhanced capability will have a dramatic impact on patient survival and quality of life.

EVIDENT's aim is to test if ex vivo drug screening can predict whether patients with solid cancers will respond, or not respond, to standard care treatments. Patients undergoing standard care surgery to excise their tumour, those undergoing a biopsy, or those having a fluid aspirate of a solid tumour with surplus tissue available after diagnostic use will be eligible for this study. The specimen will then be assessed with ex vivo drug screening utilising all standard therapies and therapies that are more novel and in early stages of development. The results of the ex vivo drug screen will be compared to the cancer's actual response to standard care treatments for those that undergo therapy to determine how effective the test is at predicting treatment response.

Predicting the survival of patients diagnosed with glioblastoma (GBM) is essential to guide surgical strategy and subsequent adjuvant therapies. Intraoperative ultrasound (ioUS) is a low-cost, versatile technique available in most neurosurgical departments. The images from ioUS contain biological information possibly correlated to the tumor's behavior, aggressiveness, and oncological outcomes. Today's advanced image processing techniques require a large amount of data. Therefore, the investigators propose creating an international database aimed to share intraoperative ultrasound images of brain tumors. The acquired data must be processed to extract radiomic or texture characteristics from ioUS images. The rationale is that ultrasound images contain much more information than the human eye can process. Our main objective is to find a relationship between these imaging characteristics and overall survival (OS) in GBM. The predictive models elaborated from this imaging technique will complement those already based on other sources such as magnetic resonance imaging (MRI), genetic and molecular analysis, etc. Predicting survival using an intraoperative imaging technique affordable for most hospitals would greatly benefit the patients' management.

This is an open-label, two arm study. The trial will enroll a total of up to 36 patients. Arm A will enroll up to a total of 6 evaluable patients and Arm B will enroll up to a total of 30 evaluable patients. Arm A will explore the intra-tumoral ONC201 concentrations and pharmacodynamic activity in adult EGFR-low glioblastoma patients. Arm B will determine the radiographic efficacy of ONC201 in adult recurrent EGFR-low glioblastoma patients. All patients will be treated with oral ONC201 (625 mg) twice weekly, 2 consecutive days on and 5 days off per week schedule.

Patient education plays an essential role in patient-centered care as it enhances patient satisfaction and information comprehension. However, about 40-80% of the information patients receive from healthcare professionals is forgotten and about half of the information patients remember is incorrect. To give informed consent, patients must be able to understand and recall the discussed information correctly. This is especially important in brain tumor patients, in which different treatment options determine outcome and risks. The goal of treatment in brain tumors is resection as completely as possible, without damaging healthy brain tissue. To this end, patients must understand the complex relation of the tumor to healthy brain tissue. This relation is different in each patient and three-dimensional (3D) in nature. Current two-dimensional visual tools lack the ability to properly display these complex 3D relations. In this study, we will investigate the effect of the use of 3D models in patient education, taking into account patient specific factors that might act as confounders. We will conduct a case control, multi-center study in the Radboud University Medical Center (Radboudumc) Maastricht University Medical Center (MUMC). Patients will be enrolled in the control group until inclusion for the control group is completed (n=30), after which patients will be enrolled in the intervention group (n=30). Patients will be cognitively tested using the Amsterdam Cognition Scale (ACS). After the consultation with their neurosurgeon, patients will be asked to fill out two questionnaires, consisting of two parts (patient experiences and information recall), one week apart.
