Active clinical trials for "Medulloblastoma"

Recent lab-based discoveries suggest that IDO (indoleamine 2,3-dioxygenase) and BTK (Bruton's tyrosine Kinase) form a closely linked metabolic checkpoint in tumor-associated antigen-presenting cells. The central clinical hypothesis for the GCC2020 study is that combining ibrutinib (BTK-inhibitor) with indoximod (IDO-inhibitor) during chemotherapy will synergistically enhance anti-tumor immune responses, leading to improvement in clinical response with manageable overlapping toxicity. GCC2020 is a prospective open-label phase 1 trial to determine the best safe dose of ibrutinib to use in combination with a previously studied chemo-immunotherapy regimen, comprised of the IDO-inhibitor indoximod plus oral metronomic cyclophosphamide and etoposide (4-drug combination) for participants, age 12 to 25 years, with relapsed or refractory primary brain cancer. Those previously treated with indoximod plus temozolomide may be eligible, including prior treatment via the phase 2 indoximod study (GCC1949, NCT04049669), the now closed phase 1 study (NLG2105, NCT02502708), or any expanded access (compassionate use) protocols. A dose-escalation cohort will determine the best safe dose of ibrutinib for the 4-drug combination. This will be followed by an expansion cohort, using ibrutinib at the best safe dose in the 4-drug combination, to allow assessment of preliminary evidence of efficacy.

The primary objective of this phase 1 trial is to determine the maximum tolerated dose (MTD), food effect, safety and tolerability of oral ONC206 in patients with recurrent, primary CNS neoplasms.

Loc3CAR is a Phase I clinical trial evaluating the use of autologous B7-H3-CAR T cells for participants ≤ 21 years old with primary CNS neoplasms. B7-H3-CAR T cells will be locoregionally administered via a CNS reservoir catheter. Study participants will be divided into two cohorts: cohort A with B7-H3-positive relapsed/refractory non-brainstem primary CNS tumors, and cohort B with brainstem high-grade neoplasms. Participants will receive six (6) B7-H3-CAR T cell infusions over an 8 week period. The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give patients with primary brain tumors.

This is a prospective randomized clinical trial, to determine whether dose-intensive tandem Consolidation, in a randomized comparison with single cycle Consolidation, provides an event-free survival (EFS) and overall survival (OS). The study population will be high-risk patients (non-Wnt and non-Shh sub-groups) with medulloblastoma, and for all patients with central nervous system (CNS) embryonal tumors completing "Head Start 4" Induction. This study will further determine whether the additional labor intensity (duration of hospitalizations and short-term and long-term morbidities) associated with the tandem treatment is justified by the improvement in outcome. It is expected that the tandem (3 cycles) Consolidation regimen will produce a superior outcome compared to the single cycle Consolidation, given the substantially higher dose intensity of the tandem regimen, without significant addition of either short-term or long-term morbidities.

This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

The current study will use a new treatment approach based on the molecular characteristics of each participant's tumor. The study will test the feasibility of performing real-time drug screening on tissue taken during surgery, and of having a specialized tumor board assign a treatment plan based on the results of this screening and genomic sequencing. The aim of this trial is to allow every child and young adult with medulloblastoma to receive the most effective and least toxic therapies currently available, and will pave the way for improved understanding and treatment of these tumors in the future.

Medulloblastoma is a rare brain malignancy, mainly affecting children. Treatment of this rapidly growing tumor begins with maximal surgical removal plus radiation and chemotherapy. Treatment toxicity is high. Post-pubertal and pediatric medulloblastomas are biologically and prognostically different, which mandates age-adapted treatment strategies. Patients after puberty bear an intermediate to high prognostic risk. This means that a large number of these patients, are faced with death and/or disability (mainly neurocognitive). Therefore, the scientific and medical need is high. One of the genetic subgroups of medulloblastoma, the SHH-subgroup (Sonic HedgeHog- subgroup), is highly overrepresented in medulloblastoma patients after puberty. This subgroup can be treated with a targeted therapy. The investigators will therefore randomize patients and treat SHH-subgroup patients with sonidegib and a reduction of radiotherapy dose in the experimental arm of the trial. The hypothesis that this personalized risk-adapted therapy will improve outcomes in view of increased efficacy and decreased toxicity.

On average, each year in the former region, 60 new patients under the age of 18 are treated for a brain tumor, with an active post-treatment follow-up file of 350 patients. Because of the significant sequelae induced by the disease or the treatments, these patients will very often require rehabilitative care. The interest of involving the horse in the population of patients cured of a medulloblastoma but with important physical and psychological after-effects is to be able to combine a therapy using animal mediation (equitherapy) and a rehabilitation therapy based on the three-dimensional movement of the horse (hippotherapy).

The efficacy of treatment with metformin for promoting cognitive recovery and brain growth in children/adolescents treated for medulloblastoma will be investigated in a multi-site Phase III randomized double-blind placebo-controlled parallel arm superiority trial. Specifically, in children/adolescents aged 7 years to 17 years and 11 months who have completed treatment for medulloblastoma, is oral administration of metformin for 16 weeks associated with greater improvement of cognitive function and brain growth compared to placebo administered for 16 weeks?

The study PNET 5 MB has been designed for children with medulloblastoma of standard risk (according to the risk-group definitions which have been used so far; e.g. in PNET 4). With the advent of biological parameters for stratification into clinical medulloblastoma trials, the ß-catenin status will be the only criterion according to which study patients will be assigned to either treatment arm PNET 5 MB - LR or to PNET 5 MB - SR, respectively. The initial diagnostic assessments (imaging, staging, histology, and tumor biology) required for study entry are the same for both treatment arms. With the amendment for version 12 of the protocol, patients who have a WNT-activated medulloblastoma with clinically high-risk features can be included in the PNET 5 MB WNT-HR study, and patients with a high-risk SHH medulloblastoma with TP53 mutation (both somatic or germline including mosaicism) can be included in the PNET5 MB SHH-TP53 study. Data on patients with pathogenic germline alteration or cancer predisposition syndrome, who cannot be included in any prospective trial due to unavailability or due to physician or family decision, can be documented within the observational PNET 5 MB registry.
