Filter by: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.
The purpose of this study is to determine if the investigational products, DB107-RRV and DB107-FC, as a combination treatment will shrink high-grade glioma (HGG) in patients with recurrent/progressive, resectable or unresectable disease and increase the time that disease is controlled.
As a part of molecular imaging, many PET tracers have been investigated in this regard. Those include 18F-FDG being glucose analogue, 18F-FLT representing nucleoside metabolism, and 18F-FDOPA, 18F-FET, 11C-MET as amino acids analogues. Among these, 18F-FDG is the most commonly used tracer due to its broader use and easy availability. However, high physiological uptake in the brain is a significant limitation. The main limitation of other tracers is the need for onsite cyclotrons for their production, making their availability difficult. So, the search for an ideal modality is still ongoing, and the latest addition to this search is a radio ligand labeled Prostate Specific Membrane Antigen (PSMA). It is a new but potentially promising radiotracer, currently showing its utility in different malignancies. Investigators, therefore, aim to identify whether Ga-68 PSMA PET-CT has better diagnostic accuracy in the detection of recurrent gliomas than conventional imaging modalities.
The purpose of this study is to find out if performing additional Magnetic Resonance Image (MRI) scans of the subjects' brain during each week of the radiation treatment of their high-grade glioma will help improve the radiation treatment.
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.
Recent advances in technology have allowed for the detection of cell-free DNA (cfDNA). cfDNA is tumor DNA that can be found in the fluid that surrounds the brain and spinal cord (called cerebrospinal fluid or CSF) and in the blood of patients with brain tumors. The detection of cfDNA in blood and CSF is known as a "liquid biopsy" and is non-invasive, meaning it does not require a surgery or biopsy of tumor tissue. Multiple studies in other cancer types have shown that cfDNA can be used for diagnosis, to monitor disease response to treatment, and to understand the genetic changes that occur in brain tumors over time. Study doctors hope that by studying these tests in pediatric brain tumor patients, they will be able to use liquid biopsy in place of tests that have more risks for patients, like surgery. There is no treatment provided on this study. Patients who have CSF samples taken as part of regular care will be asked to provide extra samples for this study. The study doctor will collect a minimum of one extra tube of CSF (about 1 teaspoon or 5 mL) for this study. If the patients doctor thinks it is safe, up to 2 tubes of CSF (about 4 teaspoons or up to 20 mL) may be collected. CSF will be collected through the indwelling catheter device or through a needle inserted into the lower part of the patient's spine (known as a spinal tap or lumbar puncture). A required blood sample (about ½ a teaspoon or 2 3 mL) will be collected once at the start of the study. This sample will be used to help determine changes found in the CSF. Blood will be collected from the patient's central line or arm as a part of regular care. An optional tumor tissue if obtained within 8 weeks of CSF collection will be collected if available. Similarities between changes in the DNA of the tissue that has caused the tumor to form and grow with the cfDNA from CSF will be compared. This will help understand if CSF can be used instead of tumor tissue for diagnosis. Up to 300 people will take part in this study. This study will use genetic tests that may identify changes in the genes in the CSF. The report of the somatic mutations (the mutations that are found in the tumor only) will become part of the medical record. The results of the cfDNA sequencing will be shared with the patient. The study doctor will discuss what the results mean for the patient and patient's diagnosis and treatment. There will not be any germline sequencing results reported and these will not be disclosed to the patient, patient's clinician or be recorded in patient medical record. Patient may be monitored on this study for up to 5 years.
The goal of this study is to determine the efficacy of the study drugs ribociclib and everolimus to treat pediatric and young adult patients newly diagnosed with a high-grade glioma (HGG), including DIPG, that have genetic changes in pathways (cell cycle, PI3K/mTOR) that these drugs target. The main question the study aims to answer is whether the combination of ribociclib and everolimus can prolong the life of patients diagnosed with HGG, including DIPG.
The goal of this study is to perform genetic sequencing on brain tumors from children, adolescents, and young adult patients who have been newly diagnosed with a high-grade glioma. This molecular profiling will decide if patients are eligible to participate in a subsequent treatment-based clinical trial based on the genetic alterations identified in their tumor.
The goal of this clinical trial is to learn about treatment for a type of brain cancer called glioma. This clinical trial is for people with glioma who have been cancer-free for a period of time but their cancer has come back. The primary goals of this clinical trial are the following: - To determine the recommended dose of PCI-24781/Abexinostat with metronomic temozolomide - To evaluate side effects associated with using PCI-24781/Abexinostat with metronomic temozolomide
This phase I/II trial tests the safety, side effects, and best dose of selinexor given in combination with standard radiation therapy in treating children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) with a genetic change called H3 K27M mutation. It also tests whether combination of selinexor and standard radiation therapy works to shrink tumors in this patient population. Glioma is a type of cancer that occurs in the brain or spine. Glioma is considered high risk (or high-grade) when it is growing and spreading quickly. The term, risk, refers to the chance of the cancer coming back after treatment. DIPG is a subtype of HGG that grows in the pons (a part of the brainstem that controls functions like breathing, swallowing, speaking, and eye movements). This trial has two parts. The only difference in treatment between the two parts is that some subjects treated in Part 1 may receive a different dose of selinexor than the subjects treated in Part 2. In Part 1 (also called the Dose-Finding Phase), investigators want to determine the dose of selinexor that can be given without causing side effects that are too severe. This dose is called the maximum tolerated dose (MTD). In Part 2 (also called the Efficacy Phase), investigators want to find out how effective the MTD of selinexor is against HGG or DIPG. Selinexor blocks a protein called CRM1, which may help keep cancer cells from growing and may kill them. It is a type of small molecule inhibitor called selective inhibitors of nuclear export (SINE). Radiation therapy uses high energy to kill tumor cells and shrink tumors. The combination of selinexor and radiation therapy may be effective in treating patients with newly-diagnosed DIPG and H3 K27M-Mutant HGG.
