Filter by:To distinguish various molecular subtypes of gliomas by spectra data obtained from Raman analyzer, including IDH mutant, 1p/19q-codeleted, ATRX deletion, TERT promoter mutation, MGMT promoter methylation, EGFR amplification, H3 K27-altered, TP53 mutant, PTEN deficiency, ki 67, AQP4, VEGF, and so on, comparing with the results of Immunohistochemistry or genetic test on the same brain tissue samples.
This is an open label, Phase 1b safety, dose-finding, brain tumor delivery, and pharmacokinetics study of intranasal NEO100 in patients with pediatric-type diffuse high grade gliomas. Patients will receive IN NEO100 that will follow a dose titration design, followed by a standard dose escalation design to establish safety. Brain tumor delivery of NEO100 will be confirmed in each disease sub-type by surgical resection/needle biopsy only if clinically indicated and scheduled for clinical purposes and testing with residual tissue for NEO100 and the major metabolite of NEO100 (Perillic Acid).
This is a dose exploration clinical trial to assess the safety and feasibility of the IL13Ra2-targeted CAR-T in glioma.
Tumors of the central nervous system affect 21 people per 100,000 every year, a figure that refers to countries with advanced economies, with an increase in incidence over time. Experimental evidence suggests that cancer stem cells (CSCs) may play a key role in the malignancy of these tumors. In fact, due to the hypoxic tumor microenvironment, these cells are able to create compensatory pathways that confer stem-like, angiogenic and pro-tumoral functions. Furthermore, it has been demonstrated that brain tumor stem cells are radio- and chemo-resistant and therefore not treatable with the therapeutic protocols currently in use. To date, in fact, there are no definitive treatments for the eradication of brain tumors. In this scenario, sphingolips, a class of lipid deputized to several physiological functions, are also involved in tumor onset, progression, drug resistance, and aggressiveness. In hypoxic tumor microenvironment, CSCs present a modified rheostat in the metabolism of sphingolipid, in favor of Sphingosine-1-phosphate (S1P). S1P is an intermediate of sphingolipid metabolism, formed from sphingosine through the action of sphingosine kinases (SK). Increasing evidence suggests that S1P acts as a tumor-promoting signal, predominantly in the extracellular environment, regulating important cellular properties correlated with tumor potential. The project aims to identify new molecular and metabolic targets involved in the survival and chemo-resistance of tumor stem cells in relation to the tumor microenvironment.
Background: Glioblastoma (GBM) is a cancer of the brain. Current survival rates for people with GBM are poor; survival ranges from 5.2 months to 39 months. Most tumors come back within months or years after treatment, and when they do, they are worse: Overall survival drops to less than 10 months. No standard treatment exists for people whose GBM has returned after radiation therapy. Objective: To find a safe schedule for using radiation to treat GBM tumors that returned after initial radiation treatment. Eligibility: People aged 18 years and older with grade 4 GBM that returned after initial radiation treatment. Design: Participants will be screened. They will have a physical exam with blood tests. A sample of tumor tissue may be collected. Participants will undergo re-irradiation planning: They will wear a plastic mask over their head during imaging scans. These scans will pinpoint the exact location of the tumor. This spot will be the target of the radiation treatments. Participants will undergo radiation treatment 4 times per week. Some people will have this treatment for 3 weeks, some for 2 weeks, and some for 1 week. Blood tests and other exams will be repeated at each visit. Participants will complete questionnaires about their physical and mental health. They will answer these questions before starting radiation treatment; once a week during treatment; and at intervals for up to 3 years after treatment ends. Participants will have follow-up visits 1 month after treatment and then every 2 months for 6 months. Follow-up clinic visits will continue up to 3 years. Follow-ups by phone or email will continue an additional 2 years....
This phase I trial tests the safety and side effects, and best dose of a vaccine (neoantigen-target ppDC) in treating patients with H3 G34-mutant diffuse hemispheric glioma. Vaccines made from the patient's own white blood cells and peptide-pulsed dendritic cells may help the body build an effective immune response to kill tumor cells. Giving neoantigen-targeted ppDC may be safe, tolerable and/or effective in treating patients with diffuse hemispheric glioma with a H3 G34 mutation.
The goal of this study is to determine the response of the study drug loratinib in treating children who are newly diagnosed high-grade glioma with a fusion in ALK or ROS1. It will also evaluate the safety of lorlatinib when given with chemotherapy or after radiation therapy.
Gliomas are the most common type of primary brain tumors, with surgery followed by radiotherapy and chemotherapy as the main treatment modalities. However, they are highly prone to recurrence, presenting significant treatment challenges, especially for high-grade gliomas, which have a 5-year survival rate of only 5.5%. Paclitaxel, a common chemotherapeutic agent, exhibits antitumor effects in vitro that are 1400 times stronger than those of temozolomide (the first-line chemotherapy drug for gliomas). However, due to its large molecular weight (approximately 893 Da), it cannot cross the blood-brain barrier, precluding its use as a first-line treatment for gliomas. Preliminary research by our team has demonstrated that Specific Mode Electroacupuncture Stimulation (SMES) can open the blood-brain barrier, enhancing the concentration of albumin-bound paclitaxel (ABX) in tumor tissues, peritumoral tissues, and surrounding invasive tissues, thereby exerting antitumor effects. Consequently, this study aims to observe the safety and efficacy of SMES combined with ABX in treating patients with recurrent high-grade gliomas postoperatively, to explore its mechanisms of action, extend survival, improve quality of life, and forge new theories and methods for the integrative treatment of brain tumors combining traditional Chinese and Western medicine.
This will be a prospective, open-label, single-arm pilot study to investigate the safety and efficacy of Bevacizumab (BEV) in combination with microbubble (MB)-mediated FUS in patients with recurrent GBM. BEV represents the physician's best choice for the standard of care (SoC) in rGBM after previous treatment with surgery (if appropriate), standard radiotherapy with temozolomide chemotherapy, and with adjuvant temozolomide.
The purpose of this study is to form an interdisciplinary team to dynamically evaluate patient cognitive outcomes and develop an individualized cognitive training program for Chinese brain tumor patients
