NCT04870944
This phase I/II trial evaluates the best dose, side effects and possible benefit of CBL0137 in treating patients with solid tumors, including central nervous system (CNS) tumors or lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Drugs, such as CBL0137, block signals passed from one molecule to another inside a cell. Blocking these signals can affect many functions of the cell, including cell division and cell death, and may kill cancer cells.
NCT07238322
This study is designed to prospectively analyze \[18F\]FET PET image data obtained retrospectively in the routine clinical care of glioma patients. The study will analyse the data from participants with grade (1-4) glioma after primary treatment according to local clinical practice and with suspicion of progression/recurrence on magnetic resonance imaging (MRI).
NCT07046481
The project intends to study physical functional capacity and degree of physical activity health related quality of life and fatigue. Also, we aim to study if the Physical Activity on Prescription (PAP) intervention is a useful method among physically inactive childhood cancer survivors to increase level of activity. The questions the study aim to answer: * What is the physical functional capacity, degree of physical activity, health related quality of life and fatigue among childhood cancer survivors 5- 10 yars after dignosis? * Is the Physical Activity on Prescription intervention feasible for physically inactive childhood cancer survivors and what effect do they experience in terms of physical functioning, physical activity, sedentary behavior, fatigue and health-related quality of life? Participants aged 5-17 years who have been treated for leukemia or brain tumor will be invited to participate. Physical functional capacity and degree of physical activity are assessed with standardized assessment instruments by a physiotherapist. Prior to the visit, participants are also asked to complete questionnaires on HRQoL and fatigue. Participants identified as physically inactive are offered to participate in a PAP intervention. Functional ability scores from previous studies are used as a baseline and are supplemented with objective measurements of physical activity and followed up after the intervention.
NCT00308165
This study will evaluate the safety and efficacy of a chemotherapeutic drug (topotecan) as it is given directly into brain tumors by a delivery technique called convection-enhanced delivery. This drug has been used for different types of cancer, but in this study it will be given by an experimental delivery technique designed to maximize the amount of drug delivered to the brain tumor and minimize the side effects in other parts of the body. This study will also evaluate advanced magnetic resonance (MR) imaging techniques. The study will assess quality of life parameters throughout the follow-up period.
NCT05776706
The goal of this clinical trial is to test augmented reality (AR) based neuronavigation system in surgeries for patients of brain neoplasm or cerebral vascular disease. The main questions it aims to answer are: • AR based neuronavigation system can achieve accuracy that is not inferior to conventional intraoperative navigation system. Participants will participate the study after informed consent. When participants undergo surgery for their brain tumor, we will set up 2 types of neuronavigation, conventional navigation system and developed AR based neuronavigation system. Surgeon will plan and conduct surgery based on only conventional navigation system, but 3D errors at several selected points between two types of navigation will be measured and analyzed.

Brain tumors are the leading cause of death from solid tumors in children. Tumor imaging is important in the management of these tumors, but current imaging methods have limitations in providing the necessary information for optimal treatment of these patients. The goal of this study is to evaluate the potential utility of positron emission tomography (PET) with 3'-deoxy-3'-\[F-18\] fluorothymidine (18F-FLT) in the medical management of brain tumors in children. Funding source - FDA Office of Orphan Product Development (OOPD)
NCT01638130
The purpose of this study is to explore the experiences and needs of patients with a high-grade glioma and their caregivers. Semi-structured interviews with patients and caregivers will be conducted and analysed using Grounded-Theory approach.
NCT05776602
This study aims to assess the diagnostic performance of a new fast MRI sequence named Neuromix compared to routine clinical MRI for brain tumor in pediatric patients
NCT05267158
The incidence of brain metastases is expected to increase because of better treatments of primary tumours. Novel diagnostic and therapeutic techniques are continuously being developed, all of which need thorough evaluation before they can be implemented in clinical routine. Randomized Controlled Trials are the gold standard to do so, but they have shown many challenges, especially when applied in a cancer setting. .The 'cohort multiple Randomized Controlled Trial (cmRCT)' design is a promising design for multiple (simultaneous) randomized evaluations of experimental interventions, with potential for increased recruitment, comparability and long-term outcomes as a standard. This design will speed up the process of translating treatment innovations to the daily clinic.
NCT02881957
Vitamin D has been shown to impact prognosis in a variety of retrospective and randomized clinical trials within an intensive care unit (ICU) environment. Despite these findings, there have been no studies examining the impact of hypovitaminosis D in specialized neurocritical care units (NCCU). Given the often significant differences in the management of patients in NCCU and more generalized intensive care units there is a need for further inquiries into the impact of low vitamin D levels in this specific environment. This study proposes a randomized, double-blinded, placebo-controlled, single center evaluation of vitamin D supplementation in the emergent NCCU patient population. The primary outcome will involve length-of-stay for emergent neurocritical care patients. Various secondary outcomes, including in-hospital mortality, ICU length-of-stay, Glasgow Outcome Score on discharge, complications and quality-of-life metrics. Patients will be followed for 6 months post-discharge.
NCT01599052
There is ample evidence that children treated for a brain tumour (BT) often develop deficits in social and emotional functioning. The investigators wish to examine the cause of these deficits, i.e. the underlying neuropsychological deficit(s). The aim is to study impairment and developmental delay in social cognition (and related cognitive functions) caused by brain damage in patients treated for a BT in childhood as compared to a reference group of chronically ill children. If we can identify the specific deficits these patients experience, neuropsychological treatment and guidance can be developed to give patients the most optimal chances to live as normal as possible, to improve their quality of life (QoL) and to prevent them from developing depression and anxiety. Eventually, an intervention programme could be developed based on our results, to improve social, vocational and emotional QoL.
NCT00592865
Study Objective: Brain tumors are poorly understood. The purpose of this research is to examine whether factors in lifestyle play a role in brain tumor development. The study will also investigate the contribution of inherited susceptibility to the risk of brain cancer. By gaining a better understanding of these influences, the investigators hope to learn how to prevent brain tumors in future generations, and to develop more effective strategies for treatment. Study Protocol: This is a case-control investigation. Persons affected with a brain tumor are compared to unaffected persons on previous medical history, diet and other factors. Those enrolled in the study will participate in an interview on general background, diet, medical history and lifestyle, and will provide a sample of DNA, clippings of your toenails, and a tap water sample from your home. All procedures are performed in the clinic or through the mail. 'Cases': Cases eligible for the study are persons with a recent diagnosis of a primary brain tumor (glioma or meningioma), at least 18 years of age. 'Controls': Controls in the study are non-family members of patients, similar in age and of the same gender. Suitable controls include in-laws, friends, neighbors and co-workers.
NCT02692898
Background: The number of people who get tumors of the brain or central nervous system (CNS) is lower than other cancers. But these tumors cause a higher rate of serious effects and even death. Researchers want to test existing samples of tissue from these tumors to learn more about them. This may lead to better treatment. Objective: To study stored samples of CNS tumors to learn more about the tumors and explore new ways to diagnose them. Eligibility: The study will use tissue samples already collected at NIH from people with brain or CNS tumors. Design: The participants will have given their consent in a previous study. Researchers will review the tissue samples and any data collected about them. Researchers will do lab tests and scans on the samples. All data will be kept secure.

HS-1000 device, a proprietary new non-invasive brain monitor, is expected to safely and accurately monitor physiological signs of the brain with minimal discomfort to patients, providing information about normal or abnormal brain-related conditions and providing decision-making support for physicians. Investigators hypothesis that the HS-1000 is capable of detecting and monitoring various neuropathologies, using the acoustic raw data derived from the noninvasive procedure.
NCT03910556
This study is a prospective cohort study to find the incidence of re-craniotomy and predictive factors. The secondary outcomes are to find the incidence of major non-neurological complications and predictive factors.
NCT03402425
To investigate the diagnostic value of 18F-FET PET/MRI instead of MRI alone, children and adolescents with tumor in brain or spinal cord are included and scanned primarily at our hybrid PET/MRI using the amino acid analog 18F-FET. The scans are performed at primary diagnosis, before radiation therapy, before and after operation, when relapse is suspected and three or six months after initiation of chemotherapy.
NCT00769093
The purpose of this study is to learn more about imaging changes induced by a new therapeutic agent, bevacizumab with the standard steroid, dexamethasone in patients with high grade glioma. Magnetic resonance imaging (MRI) will be used to evaluate the difference between the 2 treatments. The usual contrast agent (gadolinium) and an iron containing contrast agent called "ferumoxytol" may help us to evaluate the differences between bevacizumab and dexamethasone effects on imaging of a brain tumor called high grade glioma. For this purpose, after intravenous contrast agent injection, special MR scans (called: dynamic perfusion, blood-brain barrier (BBB) permeability measurement) will be performed to see the microvascular changes in the brain and tumor.
NCT00555984
If the anesthetic regimen can influence the serum level of inflammatory cytokines and if the levels of cytokines are related to the incidence of post operative complications, these complications may be a function of the anesthetic method. In an effort to find the best anesthetic regimen for patients undergoing craniotomy for intracranial tumors, the researchers will compare the effect of volatile anesthetic with that of total intravenous anesthesia (TIVA) on cytokine levels. The researchers will also compare the composite incidence of some common major post-operative complications after craniotomy for intracranial malignancy.
NCT02343081
The purpose of this crossover, single-dose, bioequivalence study is to compare the rate and extent of absorption of Temozolomide after the administration of the study product (Dralitem®, Monte Verde S.A.) and the reference product (Temodal®, Schering Plough) in primary Central Nervous System patients.
NCT00297024
Brain tumours often have low oxygen levels, and that makes them more resistant to radiation therapy. If patients breathe the right mixture of oxygen during treatment, radiation may work better. In this study, patients with brain tumour will undergo a special MRI test while they breathe different mixtures of oxygen and carbon dioxide to find out whether oxygen levels improve in the tumor. Patients will also be asked to repeat this MRI test during the second week of radiation therapy, as well as 3 months, 6 months and 1 year after RT. The MRI test after RT will help us understand how the blood vessels in the normal brain are affected by radiation.
