Filter by:Exploratory study to evaluate the effect and safety of the use of Ocoxin® oral solution on the quality of life of paediatric patients with advanced stage solid tumours.
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).
The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy
This phase I trial studies the impact of taking drugs (agents) that target altered brain metabolism following standard of care brain radiotherapy. Radiotherapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. However, radiotherapy can also cause harmful effects to normal brain functioning. One drug, called anhydrous enol-oxaloacetate (AEO), has previously been studied in ischemic stroke, Alzheimer's disease, Parkinson's disease, and glioma. Drugs such as AEO may help preserve or restore healthy brain function after brain radiotherapy compared to the standard practice which consists of no drugs.
This is a multi-center, prospective, self-controlled, diagnostic accuracy comparative study of Artificial Intelligence Diagnostic System for Surgical Neuropathology. The investigators will compare the diagnostic efficiency of Artificial Intelligence with that of practicing pathologists, and suppose that the diagnostic efficiency of artificial intelligence in prospective clinical data is no less than that of pathologists.
An early phase 1 for pediatric patients with recurrent or progressive CNS malignancies
Surgery is the cornerstone treatment of most pediatric CNS tumors, including astrocytomas, ependymomas, medulloblastomas, and many other pathologies. In most pediatric CNS tumors, the aim of surgery is maximal tumor resection, while preserving neurological function. Extent of tumor residual has been shown to be a major prognostic factor for progression free survival (PFS), and survival in several malignant and low-grade tumors such as medulloblastomas, ependymomas, and astrocytic tumors. 5-aminolevulinic acid (5-ALA) has been shown to be valuable in intraoperative marking of various cancers. Following oral admission, during surgery, the tumor tissue is illuminated by blue light. Tumor cells tend to metabolize 5-ALA to a porphyrin named protoporhyrin IX (PpIX). PpIX reacts with the blue light and emits a pinky color (- fluorescence). This enables the surgeon to better identify tumor cells and perform a more extensive resection. Over recent years, many studies have proven the efficacy using 5-ALA for resecting various intracranial and spinal tumors, thus achieving a better tumor control. In the suggested study, we propose using the same technique for various pediatric central nervous system tumors. We will focus on the correlation between various pathologies and the fluorescence, trying to deduce the role of 5-ALA in resection of specific pathologies. Also, we will study the safety of 5-ALA use in the pediatric population.
