Active clinical trials for "Central Nervous System Neoplasms"

This phase I trial studies the side effects and best dose of cabozantinib S-malate in treating younger patients with solid tumors that have come back or no longer respond to treatment. Cabozantinib S-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

RATIONALE: In this study a combination of anti-cancer drugs (chemotherapy) is used to treat brain tumors in young children. Using chemotherapy gives the brain more time to develop before radiation is given. The chemotherapy in this study includes the drug methotrexate. This drug was an important part of the two clinical trials which resulted in the best survival results for children less than 3 years of age with medulloblastoma. Most patients treated on this trial will also receive radiation which is carefully targeted to the area of the tumor. This type of radiation (focal conformal or proton beam radiotherapy) may result in fewer problems with thinking and learning than radiation to the whole brain and spinal cord. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with radiation therapy works in treating young patients with newly diagnosed central nervous system tumors.

Drugs used in chemotherapy, such as vincristine, cisplatin, and cyclophosphamide, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with chemotherapy may kill more tumor cells. Autologous stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. It is not yet known which radiation therapy regimen combined with chemotherapy and donor stem cell transplant is more effective in treating medulloblastoma, supratentorial primitive neuroectodermal tumor, or atypical teratoid rhabdoid tumor. This phase III trial is studying two different regimens of radiation therapy when given together with chemotherapy and autologous stem cell transplant to see how well they work in treating patients with newly diagnosed medulloblastoma, supratentorial primitive neuroectodermal tumor, or atypical teratoid rhabdoid tumor. PRIMARY OBJECTIVE: To assess the relationship between ERBB2 protein expression in tumors and progression-free survival probability for patients with medulloblastoma. To estimate the frequency of mutations associated with SHH and WNT tumors (as defined by gene expression profiling) via targeted sequencing performed in an independent cohort of WNT and SHH tumors (also defined by gene expression profiling).

This is a Phase 1 study of central nervous system (CNS) locoregional adoptive therapy with autologous CD4+ and CD8+ T cells that are lentivirally transduced to express an EGFR806 specific chimeric antigen receptor (CAR) and EGFRt. CAR T cells are delivered via an indwelling catheter into the tumor cavity or the ventricular system in children and young adults with recurrent or refractory EGFR-positive CNS tumors. The primary objectives of this protocol are to evaluate the feasibility, safety, and tolerability of CNS-delivered fractionated CAR T cell infusions employing intra-patient dose escalation. Subjects with supratentorial tumors will receive sequential EGFR806-specific CAR T cells delivered into the tumor resection cavity, subjects with infratentorial tumors will receive sequential CAR T cells delivered into the fourth ventricle, and subjects with leptomeningeal disease will receive sequential CAR T cells delivered into the lateral ventricle. The secondary objectives are to assess CAR T cell distribution within the cerebrospinal fluid (CSF), the extent to which CAR T cells egress into the peripheral circulation, and EGFR expression at recurrence of initially EGFR-positive tumors. Additionally, tumor response will be evaluated by magnetic resonance imaging (MRI) and CSF cytology. The exploratory objectives are to analyze CSF specimens for biomarkers of anti-tumor CAR T cell presence and functional activity.

This is a Phase 2, non-randomised, open-label, multicentric study to investigate the efficacy and safety of pembrolizumab monotherapy in 7 cohorts of patients with specific rare cancers who have unresectable locally advanced or metastatic disease, which is resistant or refractory to standard therapy, or for which standard therapy does not exist, or is not considered appropriate, and for which no other experimental treatment options are available, in order to identify subsets of patients that may benefit from treatment

This phase II Pediatric MATCH trial studies how well selumetinib sulfate works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with MAPK pathway activation mutations that have spread to other places in the body and have come back or do not respond to treatment. Selumetinib sulfate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES: To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum. To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE: To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.

The PIRATE study tests the experimental drug RRx-001 in combination with 2 chemotherapy drugs that are commonly used in patients with cancer. RRx-001 has been used alone and with other anti-cancer medicines in adults. However, the investigators do not know what effects it will have in children and young adults.

SJELIOT is a phase 1 trial that aims to explore the combination of prexasertib with established DNA-damaging agents used in medulloblastoma to evaluate tolerance and pharmacokinetics in recurrent or refractory disease. Additionally, a small expansion cohort will be incorporated into the trial at the combination MTD/RP2D (maximum tolerated dose/recommended phase two dose) to detect a preliminary efficacy signal. Stratum A: Prexasertib and Cyclophosphamide Primary Objectives To determine the safety and tolerability and estimate the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of combination treatment with prexasertib and cyclophosphamide in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma and recurrent/refractory sonic hedgehog (SHH) medulloblastoma. To characterize the pharmacokinetics of prexasertib in combination with cyclophosphamide. Secondary Objectives To estimate the rate and duration of objective response and progression free survival (PFS) associated with prexasertib and cyclophosphamide treatment in this patient population. To characterize the pharmacokinetics of cyclophosphamide and metabolites. Stratum B: Prexasertib and Gemcitabine Primary Objectives To determine the safety and tolerability and estimate the MTD/RP2D of combination treatment with prexasertib and gemcitabine in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma. To characterize the pharmacokinetics of prexasertib in combination with gemcitabine. Secondary Objectives To estimate the rate and duration of objective response and PFS associated with prexasertib and gemcitabine treatment in this patient population. To characterize the pharmacokinetics of gemcitabine and gemcitabine triphosphate (only at St. Jude Children's Research Hospital).

This phase I trial studies the side effects and best dose of selinexor in treating younger patients with solid tumors or central nervous system (CNS) tumors that have come back (recurrent) or do not respond to treatment (refractory). Drugs used in chemotherapy, such as selinexor, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
