Summary: QARIN 1 is a study of [18F]DPA-714 Translocation Protein (TSPO) Positron Emission Tomography (PET) for longitudinal, quantitative assessment of brain neuroinflammation following whole brain radiation therapy. This TSPO PET, uses a radioactive tracer. An optional MRI (magnetic resonance imaging) will also be performed to monitor brain microstructure damages induced by neuroinflammation.~Primary Obj...

Summary: A pilot pharmacokinetic trial to determine the safety and efficacy of a flavored, orally administered irinotecan VAL-413 (Orotecan®) given with temozolomide for treatment of recurrent pediatric solid tumors including but not limited to neuroblastoma, rhabdomyosarcoma, Ewing sarcoma, hepatoblastoma and medulloblastoma

Summary: The purpose of this study is to examine the use of tozuleristide and the Canvas imaging system during surgical resection of primary central nervous system tumors, to identify which tumor types demonstrate detectable fluorescence following administration of 24 mg tozuleristide and imaged with the Canvas imaging system during surgical resection, and, among tumors that demonstrate fluorescence, to es...

Summary: Children and adolescents diagnosed with medullablastoma and with recurrent or refractory to frontline therapy will be treated with 177Lu-DTPA-omburtamab, which is a radioactive labelling of a murine monoclonal antibody targeting B7-H3.

Summary: The aim of this study is to assess the safety and efficacy of AloCELYVIR, which consist in bone marrow-derived allogenic mesenchymal stem cells infected with an oncolytic Adenovirus, ICOVIR-5. It has recently been proven that this type of cells are able of transporting oncolytic substances to tumor targets that are difficult to reach, such as medulloblastomas and gliomas, youth cancers located in ...

Summary: Difluoromethylornithine (DFMO) will be used in an open label, multicenter, study as Maintenance Therapy for Molecular High Risk/Very High Risk and Relapsed/Refractory Medulloblastoma.

Summary: Medulloblastoma is a rapidly-growing tumor of the cerebellum, this area controls balance, posture and sophisticated motor functions like finer hand movements, speech, and swallowing. With the goal of, complete resection, major complications during tumor removal are usually caused by damage to the brain stem and injury to the lower cranial nerves.It has been reported that those children present Ata...

Summary: This phase I trial investigates the side effects of brain tumor-specific immune cells (IL13Ralpha2-CAR T cells) in treating patients with leptomeningeal disease from glioblastoma, ependymoma, or medulloblastoma. Immune cells are part of the immune system and help the body fight infections and other diseases. Immune cells can be engineered to destroy brain tumor cells in the laboratory. IL13Ralpha2...

Summary: This phase I trial investigates the side effects and effectiveness of chemotherapy followed by a donor (allogeneic) stem cell transplant when given to patients with high grade brain cancer. Chemotherapy drugs, such as fludarabine, thiotepa, etoposide, melphalan, and rabbit anti-thymocyte globulin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping th...

Summary: One of the major complications of posterior fossa surgery is Posterior Fossa Syndrome (PFS). This syndrome is due to a possible complication of surgical excision of a tumor of the cerebellum (4th ventricle) and is characterized by transient postoperative mutism, dysarthria, behavioral, and affective disorders, as well as motor disorders. PFS is thought to be related to axonal lesions. The long-ter...

Summary: The study's purpose is to see if the drug abemaciclib is safe and effective in combination with temozolomide and irinotecan (Part A) and abemaciclib in combination with temozolomide (Part B) in pediatric and young adult participants with relapsed/refractory solid tumors.

Summary: This study is a prospective single-center clinical study, which aims to observe and evaluate the efficacy and safety of apatinib combined with temozolomide and oral etoposide in the treatment of recurrent medulloblastoma in children.
