To learn if the study drug, ulixertinib, can cross over the blood-brain barrier in patients with recurrent brain tumors
NCT03154996
The primary goal of this study is to establish, for the first time, safety of prolonged intracerebral convection enhanced delivery of chemotherapy in patients with recurrent high grade glioma (HGG). Secondary objectives will include determination of topotecan (TPT) distribution and radiographic tumor response with prolonged continuous intracerebral convection-enhanced delivery (CED).
NCT07439172
Better treatments are needed for high-grade gliomas (HGG), and new ways of treating this disease should be tested. The investigators want to see if giving medicine before radiation works well. After radiation, MRI scans can be harder to understand because radiation changes how the brain looks on the scan. If new medicines are given before radiation, the scans are easier to read. First, the investigators need to find out if giving chemotherapy early works using a drug we already know can treat gliomas. The investigators will start with temozolomide, which is the only chemotherapy approved by the FDA for HGG. If this approach is successful, the investigators can then test new drugs using this screening method.
NCT03389802
This phase I trial studies the side effects and best dose of APX005M in treating younger patients with primary malignant central nervous system tumor that is growing, spreading, or getting worse (progressive), or newly diagnosed diffuse intrinsic pontine glioma. APX005M can trigger activation of B cells, monocytes, and dendritic cells and stimulate cytokine release from lymphocytes and monocytes. APX005M can mediate a direct cytotoxic effect on CD40+ tumor cells.
NCT07391215
The purpose of this clinical trial is to evaluate the safety and tolerability of paxalisib in combination with temozolomide and to determine the preliminary antitumour activity of the combination therapy. In the Phase 1b of this study parallel biomarker defined arms will be opened in the front-line unmethylated MGMT setting, enrolling 10 patients onto each arm. These patients will be treated with paxalisib in combination with temozolomide (TMZ). The starting dose of paxalisib will be 45mg once a day (OD) with the option of increasing to 60 mg (30 mg BD) in Cycle 2. TMZ will be administered once daily by mouth on days 1 to 5 in a 28-day cycle, with a starting dose of 150mg/m2 during cycles 1 and 2, and subsequent dose escalation to 200mg/m2 at the start of cycle 3 if cycles 1 and 2 have been well tolerated with no significant toxicity.
NCT07342699
The goal of this observational study is to learn if refined anatomical location-combined with molecular biomarkers-can predict surgical success and long-term survival in 450 adults and children with cerebellar gliomas who underwent microsurgical resection at a single center between 2014 and 2024. The main questions it aims to answer are: 1. Does tumor location (cerebellar hemisphere, vermis, fourth ventricle, or pontocerebellar-angle region) independently influence extent of resection and overall survival after adjustment for WHO grade and molecular profile? 2. Among IDH-wild-type low-grade gliomas, does gross-total resection plus early adjuvant radiotherapy improve 5-year overall and progression-free survival compared with lesser resection or radiotherapy omission? Researchers compared four anatomical subgroups and multiple molecular subtypes (IDH, 1p/19q, MGMT, TERT, BRAF V600E) to quantify location-specific resection rates, complication rates, and survival outcomes. Participants underwent standardized pre-operative imaging, microsurgical resection with intra-operative monitoring when indicated, post-operative MRI within 48 h to quantify residual tumor, and longitudinal clinical and radiographic follow-up every 3-12 months for up to 10 years.

This study consists of 2 cohorts, Cohorts A, and B, and will enroll approximately 82 participants into each cohort. Participants will receive pemigatinib 13.5 mg QD on a 2-week on-therapy and 1-week off-therapy schedule as long as they are receiving benefit and have not met any criteria for study withdrawal.
NCT06910306
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for the treatment of recurrent Glioblastoma
NCT07198256
This study aims to establish a large-scale, multi-center MRI database for malignant brain tumors. It will develop an artificial intelligence system for the segmentation and classification of multiple subtypes of brain tumors (including glioma, metastatic tumor and lymphoma et al.) using deep learning technology. This will address the issues of small sample sizes and limited classification performance in existing methods, thereby improving the accuracy of non-invasive preoperative diagnosis, reducing the need for biopsies, and having significant clinical translational value.
NCT01107522
The purpose of this study is to determine the safety, tolerability, and the maximum tolerated dose/recommended phase II dose of carboxyamidotriazole orotate (CTO) as a single agent in patients with advanced or metastatic solid tumors; in combination with oral Temodar® in patients with glioblastoma or other recurrent malignant gliomas; or in combination with oral Temodar® and radiation therapy in patients with newly diagnosed glioblastoma or other malignant gliomas.
NCT01734512
This is an open label study of everolimus in children with recurrent or progressive low-grade glioma.
NCT01748149
This is a multicenter, safety and pharmacokinetic trial to determine the MTD and/or select a recommended phase 2 dose (RP2D) of vemurafenib in children with recurrent or refractory gliomas containing the BRAFV600E or BRAF Ins T mutation.
NCT07020052
This study is a phase II single center exploratory clinical trial aimed at evaluating the efficacy and safety of temozolomide combined with anlotinib synchronous radiotherapy sequential triple therapy (temozolomide/anlotinib/PD-L1 inhibitor) for the maintenance treatment of diffuse midline gliomas (DMG) in children. The research plan includes 33 children with DMG aged 3-18 years, who have been pathologically diagnosed and have not received systematic treatment. The implementation will be divided into two stages: synchronous radiotherapy and chemotherapy stage (54Gy radiotherapy+oral temozolomide 75mg/m ²+sequential oral anlotinib) and maintenance treatment stage (increasing temozolomide dose+continuous use of anlotinib+intravenous injection of PD-L1 inhibitor according to body weight). Through multi mechanism synergy (radiotherapy sensitization, anti angiogenesis, and immune activation), the limitations of traditional treatment will be overcome. The primary endpoint is progression free survival (PFS), while secondary endpoints include objective response rate (ORR), 2-year overall survival rate (2y OS), quality of life, and safety (CTCAE 4.0 criteria). The innovation of the research lies in the first proposal of a "synchronous maintenance" staged mode, targeting the molecular characteristics of DMG (H3K27M mutation), combined with previous evidence at home and abroad (such as the median PFS of 10.2 months for anlotinib combined with synchronous radiotherapy), aiming to provide a new comprehensive treatment plan for this highly invasive tumor.
NCT07017816
This clinical trial is studying a drug called SGT-53 along with radiation and another drug called Nivolumab. It's for children with brain tumors that have come back, gotten worse, or didn't get better with earlier treatments. The main questions it aims to answer are: What is the right dose of SGT-53 that children can safely receive when it is used with radiation and Nivolumab? This dose will be used in the second phase of the trial. What side effects are there of SGT-53 when it is used with radiation and Nivolumab? How does SGT-53 move through the body when given with radiation and Nivolumab? How much of the SGT-53 drug is found in the tumor tissue? This will be tested in a small group of patients? Participants will: For the first treatment cycle: Get SGT-53 twice per week Get Nivolumab every 2 weeks Receive radiation therapy during week 2 For Cycles 2-6: Get SGT-53 once per week during even cycles and twice per week during odd cycles Get Nivolumab every 2 weeks For Cycles 7+ Get both SGT-53 and Nivolumab every 2 weeks In the phase 0 part of the study, 4 participants will have genetic testing performed on their tumor tissue after receiving SGT-53. These samples will be compared to another sample taken from the skin.

Objective of the study is to determine whether intraoperative ultrasound guided resection of gliomas with contrast enhancement in magnetic resonance imaging and brain metastases can achieve as high rate of gross total resection as fluorescence-guided surgery with 5-aminolevulinic acid
NCT06632236
The purpose of this clinical trial is to evaluate the safety and tolerability of amivantamab and to determine the preliminary antitumour activity of amivantamab administered at the recommended Phase 2 dose (RP2D). In the Phase 1b of this study a biomarker defined arm will be opened, initially in the relapsed GMB setting, enrolling 12 patients. These patients will be treated with amivantamab monotherapy. Amivantamab will be administered intravenously (IV) weekly for the first 4 weeks, then every 2 weeks thereafter until disease progression or unacceptable toxicity. The first dose will be given as a split infusion, 350 mg IV over 4 hours on cycle 1 day 1 and 1400 mg IV over 6 hours on cycle 1 day 2. Subsequent infusions are given at a dose of 1750 mg IV over 2-5 hours in cycle 1 and between 2-3 hours from cycle 2 onwards if the first dose was well-tolerated with no significant toxicity. Progression to Phase 2 is dependent on emergent data and funding.

A Phase I Study Evaluating the Safety, Tolerability, Biodistribution and Shedding of the Virus, Pharmacodynamics, Immunogenicity, and Antitumor Activity of GC001 Oncolytic Vaccinia Virus Injection in Patient With Recurrent or Progressive Gliomas .
NCT06736470
Gliomas are tumors that occur in all ages; they include the most common malign primary central nervous system tumors in developed countries. Gliomas are often aggressive, and their recommended treatment is surgical resection and chemoradiation. Complete tumor removal is challenging because of diffuse cell growth and the proximity of functionally critical tissues. Surgeons use 5-aminolevulinic acid (5-ALA) drug-induced fluorescence to visually detect tumor cells, which improves resection rates and delays tumor progression. Tumor cells are often left unnoticed because of visual obstacles or weak fluorescence, which may lead to local recurrence and reoperations. Surgical suction devices are used to remove cancerous tissues, but so far the suction aspirate tissues have not been routinely used in tissue detection. This single-center observational study compares experts' visual detection of 5-ALA-induced fluorescence and fluorescence detected from the surgical suction waste. The fluorescence from the suction waste will not be reported back to the surgeon.
