Filter by:This is a multicenter, randomized, open-label phase 2/3 study of Toca 511 and Toca FC versus standard of care that comprises Investigator's choice of single agent chemotherapy (lomustine or temozolomide) or bevacizumab administered to subjects undergoing resection for first or second recurrence (including this recurrence) of GBM or AA. Subjects meeting all of the inclusion and none of the exclusion criteria will be randomized prior to surgery in a 1:1 ratio to receive either Toca 511 and Toca FC (Experimental arm, Arm T) or control treatment with one option of standard of care (Arm SOC). Stratification will be done by IDH1 mutation status. A second stratification factor is based on the patient's Karnofsky Performance Score (KPS) (70-80 vs 90-100). Further, to account for potential differences in treatment choices for the control arm in regions, the trial will be stratified by geographical region during the randomization process.

The Investigators will examine the disease specificity of 2-hydroxyglutarate in non-glioma brain lesions, and the clinical utility of 2-hydroxyglutarate, glycine and citrate in IDH mutated gliomas and IDH wild type gliomas.
By employing a combination of advanced MRI techniques and correlative serum biomarkers of blood brain barrier (BBB) disruption, the investigators plan to develop a powerful, first of its kind clinical algorithm in pediatrics whereby the investigators can measure and identify the window of maximal BBB disruption post MLA to 1) allow for an alternative to surgery in incompletely resected tumors, 2) allow for optimal chemotherapeutic dosing to achieve the greatest benefits and the least systemic side effects and 3) distinguish subsequent tumor progression from long-term MLA treatment effects. Preliminary data in adult imaging studies have shown that the BBB disruption lasts for several weeks following treatment before returning to a low baseline. This pilot therapeutic study will provide preliminary validation in pediatric patients.
This randomized phase II study will assess the impact of pre-conditioning on migration and survival among newly diagnosed glioblastoma (GBM) patients who have undergone definitive resection and completed standard temozolomide (TMZ) and radiation treatment, as well as the impact of tetanus pre-conditioning and basiliximab together on survival. After completing standard of care radiotherapy with concurrent TMZ, patients will be randomized to 1 of 3 treatment arms: 1). receive cytomegalovirus (CMV)-specific dendritic cell (DC) vaccines with unpulsed (not loaded) DC pre-conditioning prior to the 4th vaccine; 2). receive CMV-specific DC vaccines with Tetanus-Diphtheria Toxoid (Td) pre-conditioning prior to the 4th vaccine; 3). receive basiliximab infusions prior to the 1st and 2nd DC vaccines along with Td pre-conditioning prior to the 4th vaccine. A permuted block randomization algorithm using a 1:1:1 allocation ratio will be used to assign patients to a treatment arm. Randomization will be stratified by CMV status (positive, negative), with the assignment to arms I and II being double-blinded. Effective March 2017, randomization to Group III has been terminated.
This is a phase II study of the drug, pegylated interferon alfa-2b (PEG-Intron), used to treat brain tumors in a pediatric population. Researchers want to see if treatment with PEG-Intron will stop tumor growth for patients with juvenile pilocytic astrocytomas or optic pathway gliomas. The purposes of this study are: - To learn more about the response to pegylated interferon - To learn more about the side effects of pegylated interferon - To learn more about MRI images in patients with Juvenile Pilocytic Astrocytomas or Optic Pathway Gliomas. - To learn more about quality of life in patients treated with pegylated interferon
This phase I trial studies the side effects and best dose of palbociclib isethionate in treating younger patients with central nervous system tumors that have grown, come back, or not responded to treatment. Palbociclib isethionate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to test the effectiveness of a drug called temsirolimus in combination with a drug called perifosine in treating brain tumors that have continued to grow after previous treatment. Temsirolimus is an intravenous drug approved by the FDA for treatment of other cancers (kidney cancer, certain types of lymphoma) but not for brain tumors. Perifosine is a pill that has not been approved by the FDA which blocks a messenger that tells cancer cells to grow. Research suggests that combined treatment with both drugs is better than either alone, and that it is reasonably safe.
Low grade gliomas (LGGs) are the most common primary central nervous system malignancies. Brain surgeries with the most possible extent of resection are endeavored to achieve longer survivals in LGG patients. For patients with tumor located in eloquent areas so that gross total resection is not applicable, National Comprehensive Cancer Network (NCCN) 2013 guidelines assigned both radiotherapy or chemotherapy as adjuvant treatments of low grade glioma following surgeries. Retrospective studies have suggested that temozolomide (an oral chemotherapeutics) chemotherapy have good effects on the control of tumor progression or recurrence in LGG patients after surgeries, especially in those with isocitrate dehydrogenase (IDH) gene mutations. Therefore, our prospective cohort study is to provide a higher level(IIb) of evidence for the correlation between IDH mutation and the responsiveness to up-front adjuvant metronomic temozolomide chemotherapy in young patients with LGG located in eloquent brain areas. And hopefully justify future RCTs with comparison between effects of adjuvant radiotherapy and chemotherapy in these patients.
This pilot clinical trial studies gallium Ga 68-edotreotide (68Ga-DOTATOC) positron emission tomography (PET)/computed tomography (CT) in finding brain tumors in younger patients. Diagnostic procedures, such as gallium Ga 68-edotreotide PET/CT imaging, may help find and diagnose brain tumors.
This phase I trial studies the side effects and best dose of carboxylesterase-expressing allogeneic neural stem cells when given together with irinotecan hydrochloride in treating patients with high-grade gliomas that have come back. Placing genetically modified neural stem cells into brain tumor cells may make the tumor more sensitive to irinotecan hydrochloride. Irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving carboxylesterase-expressing allogeneic neural stem cells and irinotecan hydrochloride may be a better treatment for high-grade gliomas.
