Filter by:There is limited knowledge regarding the quality of life and needs of patients with advanced high grade gliomas, especially during the end of life. By doing this research, we are able to assess caregiver and patient symptoms and needs during the end of life phase of patients with brain tumors.
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.
In this research study, we want to learn about the safety of the study drugs, ribociclib and everolimus, when given together at different doses after radiation therapy. We also want to learn about the effects, if any, these drugs have on children and young adults with brain tumors. We are asking people to be in this research study who have been diagnosed with a high grade glioma, their tumor has been screened for the Rb1 protein, and they have recently finished radiation therapy. If a patient has DIPG or a Bi-thalamic high grade glioma, they do not need to have the tumor tissue screened for the Rb1 protein, but do need to have finished radiation therapy. Tumor cells grow and divide quickly. In normal cells, there are proteins that control how fast cells grow but in cancer cells these proteins no longer work correctly making tumor cells grow quickly. Both study drugs work in different ways to slow down the growth of tumor cells. The researchers think that if the study drugs are given together soon after radiation therapy, it may help improve the effect of the radiation in stopping or slowing down tumor growth. The study drugs, ribociclib and everolimus, have been approved by the United States Food and Drug Administration (FDA). Ribociclib is approved to treat adults with breast cancer and everolimus is approved for use in adults and children who have other types of cancers. The combination of ribociclib and everolimus has not been tested in children or in people with brain tumors and is considered investigational. The goals of this study are: - Find the safest dose of ribociclib and everolimus that can be given together after radiation. - Learn the side effects (both good and bad) the study drugs have on the body and tumor. - Measure the levels of study drug in the blood over time. - Study the changes in the endocrine system that may be caused by the tumor, surgery or radiation.
Malignant gliomas have a very poor prognosis with median survival measured in months rather than years. It is a disease in great need of novel therapeutic approaches. Based on the encouraging results of our preclinical studies which demonstrate improved efficacy without added toxicity, the paradigm of delivering a novel oncolytic adenovirus via a neural stem cell line in combination with radiation and chemotherapy is well-suited for evaluation in newly diagnosed malignant gliomas. The standard-of-care allows application of virotherapy as neoadjuvant therapy and assessment of the cooperative effects with radiation/chemotherapy without altering the standard treatment.
The purpose of the study is to confirm the safety of the selected dose and potential toxicity of oncolytic poliovirus (PV) immunotherapy with PVSRIPO for pediatric patients with recurrent WHO grade III or IV malignant glioma, but evidence for efficacy will also be sought. The primary objective is to confirm the safety of the selected dose of PVSRIPO when delivered intracerebrally by convection-enhanced delivery (CED) in children with recurrent WHO Grade III malignant glioma (anaplastic astrocytoma, anaplastic oligoastrocytoma, anaplastic oligodendroglioma, anaplastic pleomorphic xanthoastrocytoma) or WHO Grade IV malignant glioma (glioblastoma, gliosarcoma). A secondary objective is to estimate overall survival (OS) in this population.
The purpose of this study was to investigate the activity of dabrafenib in combination with trametinib in children and adolescent patients with BRAF V600 mutation positive low grade glioma (LGG) or relapsed or refractory high grade glioma (HGG)
This is a safety (Phase 1) trial using mebendazole for recurrent pediatric brain cancers that include medulloblastoma and high grade glioma, that are no longing responding to standard therapies. The drug mebendazole is an oral drug in a chewable 500 mg orange flavored tablet. It is already approved to treat parasitic infections. The purpose of this study is to determine the safety and side effects for increasing doses of mebendazole, followed by the treatment of an additional 12 patients at the best tolerated dose.
A recent prospective multicenter study by Dr. Grossman demonstrated that 40% of patients with high grade glioma undergoing radiation and chemotherapy developed severe and persistent lymphopenia (CD4 counts <200 cells/mm3). This lymphopenia lasted for twelve months following radiation treatment and on multivariate analysis was associated with shorter survival. Our group has data that strongly suggests that this lymphopenia is secondary to the inadvertent radiation of circulating lymphocytes as they pass through the radiation beam. Investigators propose the use of FDA approved for multiple sclerosis, fingolimod to signal lymphocytes to leave the circulation prior to the initiation of radiation. It is a functional antagonist of the sphingosine-1-phosphate receptor (S1PR) pathway and prevents lymphocyte egress from secondary lymphoid organs. Oral fingolimod will be given 1 week prior to the initiation of concurrent radiation and temozolomide and will be discontinued immediately upon completion of the six weeks of therapy. The primary objective is to evaluate if fingolimod can be safely combined with radiation and temozolomide. Secondary endpoint is total lymphocyte counts (TLC) for the proposed study participants. Investigators expect that patients receiving radiation and temozolomide plus fingolimod have a recovery of lymphocyte counts to 80% of baseline within four months, reference to historical control in which sustained lymphopenia lasted for twelve months.
This study is a clinical trial to determine the safety of injecting G207 (a new experimental virus therapy) into a recurrent or progressive brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication and tumor cell killing, will also be tested.
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.
