NCT05839379
The goal of this study is to perform genetic sequencing on brain tumors from children, adolescents, and young adult patients who have been newly diagnosed with a high-grade glioma. This molecular profiling will decide if patients are eligible to participate in a subsequent treatment-based clinical trial based on the genetic alterations identified in their tumor.
NCT06962215
The goal of this clinical trial is to demonstrate that simulation training for paramedical staff in neurosurgery departments, in announcing and accompanying patients with a brain tumor, improves patient satisfaction when a (potentially malignant) brain tumor is discovered, compared with usual care. The main question it aims to answer is: \- Are patients more satisfied (as measured by scores on the EORCT IN-PATSAT32 questionnaire) with their neurosurgical hospitalization following the discovery of a brain tumor in centers where paramedics have been trained by simulation? Researchers will compare the results of the EORTC IN-PATSAT32 questionnaire to determine whether paramedic training improves patient satisfaction between simulation-trained and untrained centers. Participants will be asked to complete the EORT IN-PATSAT32 questionnaire at the end of their hospital stay.
NCT03478462
The study evaluates CLR 131 in children, adolescents, and young adults with relapsed or refractory malignant solid tumors and lymphoma and recurrent or refractory malignant brain tumors for which there are no standard treatment options with curative potential.
NCT05588141
Background: Diffuse gliomas are tumors that affect the brain and spinal cord. Gliomas that develop in people with certain gene mutations (IDH1 or IDH2) are especially aggressive. Better treatments are needed. Objective: To see if a study drug (zotiraciclib) is effective in people with recurrent diffuse gliomas who have IDH1 or IDH2 mutations. Eligibility: People aged 15 years and older with diffuse gliomas that returned after treatment. They must also have mutations in the IDH1 or IDH2 genes. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of their heart function. They will have an MRI of their brain. A new biopsy may be needed if previous results are not available. Zotiraciclib is a capsule taken by mouth with a glass of water. Participants will take the drug at home on days 1, 4, 8, 11, 15, and 18 of a 28-day cycle. They may also be given medications to prevent side effects of the study drug. The schedule for taking the study drug may vary for participants who will undergo surgery. Participants will be given a medication diary for each cycle. They will write down the date and time of each dose of the study drug. Participants will visit the clinic about once a month. They will have a physical exam, blood tests, and tests to evaluate their heart function. An MRI of the brain will be repeated every 8 weeks. Participants may remain in the study for up to 18 cycles (1.5 years).
NCT02851706
Background: Brain and spinal cord tumors are uncommon. But they contribute substantially to cancer deaths in the U.S. in children and adults. Little progress has been made in treating brain tumors. Researchers want to learn more about these tumors by studying people who have them. Objectives: To understand brain and spinal cord tumors better and uncover areas for further research. Also, to connect people with these tumors to doctors who can help them manage their illness and give them new treatment options. Design: Participants will have an initial (baseline) visit. They will have their medical history taken and undergo physical and neurological exams. They will have blood tests. They may have scans (imaging studies) of the nervous system. If participants have urine or cerebrospinal fluid collected during their regular care, researchers may save some. Brain tumor tissue from a prior surgery may be studied. Genomic DNA testing will be done on samples. Results will be linked to participants medical and/or family history. The number of study visits at NIH will depend on the wishes of participants and their local doctors. Participants will take a brain tumor survey on a computer. They can take it all at once or in 6 separate sections. Participants will answer questions about their general well-being. They will answer questions to learn if they have symptoms of depression or anxiety. Physicians will discuss test results with participants. They will recommend management and treatment options.
NCT07257419
The purpose of this study is to learn more about newer methods of transplanting blood cells donated by a partially matched family member to children with high-risk CD19 positive leukemia ALL. Primary Objective: \- To assess the safety and feasibility of combining CD19-CAR(Mem) T cells after TCRαβ+/CD19 depleted haploidentical donor transplantation for pediatric patients with relapsed/refractory CD19+ B-cell malignancies. Secondary Objectives: * To estimate 1-year post-transplant overall survival, event-free survival, and GVHD-free relapse-free survival (GRFS). * To estimate cumulative incidence of engraftment, acute and chronic GVHD, and immune-related adverse events, including CRS and ICANS.
NCT05288439
The researchers are doing this study to find out if there are differences in the resting state brain networks of children and young adults (ages 6-25) after treatment with proton beam radiation therapy (PBRT). The researchers will use resting state functional connectivity magnetic resonance imagining (rs-fcMRI) scanning to detect these differences. The researchers will also check for differences in participants' thinking and quality of life through a cognitive assessment and a questionnaire. Both people undergoing PBRT for a brain tumor and healthy people will take part in this study so that the researchers can compare the brain networks (connections in the brain that are involved in certain function, such as memory or attention), thinking patterns, and quality of life of these two groups of participants. The study researchers think that rs-fcMRI scans may be an effective way to look at the brain networks after treatment with PBRT and see if this treatment causes differences in those networks, including damage to the brain (neurotoxicity). rs-fcMRI scans take images when a patient is in a resting state, which means the patient is not performing a task or thinking about anything in particular. This study will provide valuable information about how PBRT affects brain networks, thinking (cognitive) abilities, and quality of life in children and young adults. The study results may have an impact on future treatment approaches for brain cancer and the use of PBRT in children and young adults.
NCT07420543
Glioblastoma (GBM) is the most common and lethal primary brain tumor. Identifying blood biomarkers that reflect the tumor's status is a major unmet need for optimal clinical management. 5-ALA (5-Aminolevulinic Acid) administration leads to the accumulation of fluorescent Protoporphyrin IX (PpIX) in GBM cells, allowing identification during surgery. This project aims to leverage 5-ALA induced fluorescence to maximize the informational power of plasma liquid biopsy as a tool for diagnosis, post-treatment follow-up, and as a prognostic tool in patients with GBM.
NCT07417085
In recent years, there has been growing interest in the human gut microbiota, whose health is characterised by high microbial diversity. Through the gut-brain axis, the microbiota influences the homeostasis of the central nervous system by regulating neurological, immune and epigenetic functions. Intestinal dysbiosis is associated with various neurological and oncological diseases, including paediatric diseases and colorectal cancer. Recent studies highlight a significant link between microbiota and brain tumours: cancer patients show reduced microbial richness and altered bacterial composition. In addition, an intratumoural microbial population has been identified that can influence tumour initiation, progression and response to therapies by modulating tumour cells and the immune system. The aim of this study is to analyse stool samples to study the microbiota in children suspected CNS brain tumor as there are currently no studies of this kind reported in the literature to assess whether microbial changes can be detected at diagnosis, can be found during the course of the disease or are associated with tumour progression.
NCT07418775
Meningiomas are the most common primary brain tumor, and some groups are diagnosed with higher-grade tumors and have clinically worse outcomes. This study investigates social determinants of health and individual risk factors that may be associated with meningioma.
NCT07413796
The purpose of this study is to compare two commonly used methods of closing the skin after surgery for an intracranial tumor. Skin closure is one of the most important steps in neurosurgical procedures, as it has a major influence on how well the wound heals. In patients with brain tumors, proper wound healing is especially important because it may affect how soon additional treatments, such as radiotherapy or chemotherapy, can be started. There are different ways to close the skin after surgery, including running sutures and interrupted sutures. Both methods are widely used and considered safe. However, in oncological neurosurgery, there is limited scientific evidence comparing their effects, and the choice of technique is often based on the surgeon's personal experience. In this study, investigators will compare skin closure using running absorbable sutures with interrupted non-absorbable sutures. Investigators will evaluate how well, depending on used suturing methods, the wound heals and how often wound-related complications occur, such as infection, separation of the wound edges, or leakage of cerebrospinal fluid. Investigators believe that the results of this study will help improve wound care in patients undergoing neurosurgical treatment for brain tumors and, as a result, may contribute to better recovery and overall quality of life.
NCT06158828
This trial represents a single institution phase I/II pilot study with the primary objective of establishing the safety and feasibility of generating and infusing ML NK cells after TCRαβ haplo-HCT.
NCT07042620
The objective of this clinical investigation is to assess the safety and performance of the SonoClear® System. Performance will be assessed by analysis of the contrast-to-noise ratio (CNR) and assessment of image quality by using the Surgeon Image Rating (SIR) Scale. This is a prospective, multi-centre single arm study where the performance of the SonoClear® System relative to routinely used acoustic coupling fluid is investigated by each patient being their own control. Patients with the diagnosis of high-grade glioma (HGG) and low-grade glioma (LGG) at up to 5 sites in Germany will be included. Additionally, safety data are collected at 72 hours, 30 days and 6 months post procedure.
NCT05890781

NCT03938987
Autologous, unselected CD3+ lymphocytes collected from apheresis, transfected with a lentiviral vector containing a 2nd generation chimeric antigen receptor (CAR) consisting of a scFv recognizing CD19 and dual co-stimulatory intracellular signaling domains (4-1BB and CD3ζ).
NCT05733312
This study seeks to determine the impact of focused ultrasound (FUS) on the composition of the tumor extracellular microenvironment. Researchers will evaluate regions that are very abnormal, as well as regions that have less evidence of disease. A sub-portion of each of these areas will be targeted by focused ultrasound. Microdialysis catheters will then be placd into each region that has and has not been exposed to FUS (total of 4 catheters) to determine how FUS impacts the the brain and tumor extracellular metabolome, including concentration of routine drugs systemically administered prior to, and during surgery. Researchers hope that this information will help reveal the relative contribution of blood-derived compounds to the tumor microenvironment. If successful, microdialysis could be leveraged in the future to simultaneously evaluate pharmacokinetic and pharmacodynamic impacts of future candidate therapies, including those delivered with the aid of FUS.
NCT07338526
Children diagnosed with benign or low-grade brain tumors often require radiation therapy to control their disease. While radiation can be effective, traditional techniques using X-rays (photon-based radiotherapy) expose healthy brain tissue to radiation, potentially leading to long-term side effects like memory loss, learning difficulties, hormone imbalances, hearing problems, and a higher risk of secondary cancers. This study, called the IMPORT Trial, aims to compare two types of radiation therapy-Intensity-Modulated Proton Therapy (IMPT) and Intensity-Modulated Radiation Therapy (IMRT)-to determine which is safer and more effective for children. IMPT, a newer technique, uses protons instead of X-rays to deliver radiation, reducing exposure to healthy brain tissue. Researchers believe this could help minimize long-term damage while maintaining effective tumor control. What is the goal of the study? The primary goal is to see if IMPT leads to better survival with fewer side effects compared to IMRT. The study will track how well children function over five years, looking at: * Cognitive abilities (memory, attention, learning) * Hormonal balance (pituitary gland function) * Hearing ability * Overall survival without significant decline in quality of life How will the study work? * Who can join? Children aged 6 to 16 years diagnosed with certain types of benign or low-grade brain tumors. * How are patients treated? Patients will be randomly assigned to receive either IMRT or IMPT. * What is analysed? Doctors will track survival, tumor control, cognitive function, endocrine health, and quality of life over time. * How long will it take? The study will last 10 years (5 years to enroll patients, 5 years to follow up). Proton therapy is more expensive and not widely available, so strong scientific evidence is needed to justify its use in routine treatment. If IMPT significantly improves quality of life and survival, it could become the preferred treatment, shaping future policies and making proton therapy more accessible for children who need it.
NCT06057168
This trial aimed to study the performance of Elucirem (gadopiclenol) in Dynamic Susceptibility Contrast Magnetic Resonance Imaging (DSC-MRI) perfusion of brain gliomas.
NCT07087002
This is a single-site, open-label Phase 1 clinical trial evaluating the feasibility, safety, and preliminary activity of autologous GPC2-targeted chimeric antigen receptor (CAR) T cells administered via intracerebroventricular (ICV) infusion in children and young adults with relapsed or refractory medulloblastoma or other eligible Central Nervous System (CNS) embryonal tumors.
NCT05622682
This observational study aims to assess recovery of the immune system and immunity to vaccine-preventable diseases in children, adolescents, and young adults who recently completed treatment for acute lymphoblastic leukemia (ALL). Several children's hospitals in the United States are participating in the study, which will enroll up to 100 pediatric participants. The study is intended to determine the rate of infection after leukemia treatment and to inform future studies and recommendations about whether children and adolescents who have leukemia should receive additional vaccine doses or boosters after treatment.
