Eflornithine (DFMO) and AMXT 1501 for Neuroblastoma, CNS Tumors, and Sarcomas

The purpose of this study is to evaluate the investigational oral drug AMXT 1501 in combination with oral eflornithine (DFMO). An investigational drug is one that has not been approved by the U.S. Food \& Drug Administration (FDA), or any other regulatory authorities around the world for use alone or in combination with any drug, for the condition or illness it is being used to treat. The goals of this part of the study are: * Establish a recommended dose of AMXT 1501 in combination with DFMO * Test the safety and tolerability of AMXT 1501 in combination with DFMO * To determine the activity of study treatments chosen based on: * How each subject responds to the study treatment * How long a subject lives without their disease returning/progressing

Treatment of Relapsed/Refractory Intracranial Glioma in Patients Under 22 Years of Age

This study assesses the safety and efficacy of repeat monthly dosing of super-selective intra-arterial cerebral infusion (SIACI) of cetuximab and bevacizumab in patients \< 22 years of age.

Safety and Efficacy of Loco-regional B7H3 IL-7Ra CAR T Cell in DIPG

A Phase 1 clinical trial to evaluate the safety and early efficacy of CAR T-cell with IL-7Ra signal targeting B7H3 in children with diffuse intrinsic pontine glioma (DIPG) patients after complete standard treatments.

Clinical Study of Allogeneic Vγ9Vδ2 T Cells in the Treatment of Brain Malignant Glioma

Primary brain malignant tumor has become the first lethal tumor in children and young adults, and the treatment is limited, and the prognosis of patients is poor. According to the classification of the World Health Organization, glioblastoma is divided into grade II, III and IV gliomas; The higher the degree of malignancy, the worse the clinical outcome. Among them, the most malignant, most lethal, and most common types of tumors include supratentorial glioblastoma, diffuse endopontine glioma (DIPG), medulloblastoma, and ependymoma. Its high malignancy is mainly manifested in three aspects: extremely rapid growth and obvious invasion; The operation is not easy to remove all; The tumor has a tendency of recurrence and disseminated implantation. It can occur with children and adults of all ages. At present, surgery combined with chemoradiotherapy is the main treatment, but the therapeutic effect is not good. Studies have shown that glioblastoma, as the most common primary brain malignant tumor in adults, after standard surgery, radiotherapy and chemotherapy, the median survival time is less than 15 months, and the overall five-year survival rate is only 5.4%. Even after receiving new and expensive Tumor-treating fields, the median survival time is less than 21 months. The median survival time of DIPG patients is generally less than 1 year, and the 5-year survival rate is less than 5%. The average 5-year survival rate of medulloblastoma and anaplastic ependymoma is 40%\~60%. Innovative treatments are urgently needed. Immunotherapy based on Vγ9Vδ2 T cells has become a promising research direction in recent years. Its unique phosphine antigen recognition does not depend on major histocompatibility complex (MHC), easy to allograft and other advantages. Making it one of the most promising cell therapies. Brain glioma has abnormal cholesterol metabolism and phosphine antigen accumulation, which is easily sensed by Vγ9Vδ2 T cells. Therefore, the clinical exploration of Vγ9Vδ2 T cells for glioma is of great significance to both the scientific and clinical communities.
