Filter by:The goal of this clinical trial is to assess the safety, toxicity, and antitumor activity of fourth ventricular infusions of nivolumab plus 5-azacytidine for recurrent ependymoma and nivolumab plus methotrexate for recurrent medulloblastoma and other CNS malignancies. Additionally, the study will explore immunologic responses to nivolumab. The hypothesis is that local administration of nivolumab, an immune checkpoint inhibitor, is safe and will lead to even more robust treatment responses when administered following 5-azacytidine in patients with recurrent ependymoma or methotrexate in patients with medulloblastoma or other CNS tumors.
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.
The treatment of adolescents and young adults (AYA, 15 to 39 years) with malignant intra-axial CNS parenchymal tumors such as IDH-mutated gliomas, medulloblastomas and ependymomas is still not curative in all cases. The tumor biology and clinical needs to diagnose and treat these tumors are comparable across all age groups, so an integrated treatment environment overseen by adult and pediatric neuro-oncology specialists seems promising to leverage synergisms and advance diagnostic and therapeutic development in these tumors. A comprehensive, prospective and integrated biomaterial and imaging-based pipeline for the multi-faceted evaluation of AYAs has not yet been established for AYA patients with brain tumors in Germany. Current diagnostic platforms neglect the integrative processing of data from MRI and FET-PET imaging, radiotherapy plans, tumor tissue, liquid biopsies and clinical data as well as prognostic markers. A prospective AYA pipeline can therefore enable a better understanding of the aforementioned high-risk CNS malignancies and promises clinical advances for AYA patients and the clinical and scientific research landscape.
The purpose of this study:(1) Development of a new risk classification model for childhood medulloblastoma. (2) Evaluation and improvement of existing individualized treatment protocols.
This study will address the question of whether targeting CMV antigens with PEP-CMV can serve as a novel immunotherapeutic approach in pediatric patients with newly-diagnosed high-grade glioma (HGG) or diffuse intrinsic pontine glioma (DIPG) as well as recurrent medulloblastoma (MB). PEP-CMV is a vaccine mixture of a peptide referred to as Component A. Component A is a synthetic long peptide (SLP) of 26 amino acid residues from human pp65. The SLPs encode multiple potential class I, class II, and antibody epitopes across several haplotypes. Component A will be administered as a stable water:oil emulsion in Montanide ISA 51.

The purpose of this study is to establish the safety of infusions of panobinostat (MTX110) into the fourth ventricle of the brain or tumor resection cavity in patients with recurrent medulloblastoma and to assess the antitumor activity of simultaneous infusions of panobinostat (MTX110) into the fourth ventricle of the brain or resection cavity in patients with recurrent medulloblastoma based upon MRI scans and lumbar cerebrospinal fluid (CSF) cytology.
