Filter by:This phase 1b trial studies the side effects and best dose of telaglenastat in combination with radiation therapy and temozolomide in treating patients with IDH-mutated diffuse or anaplastic astrocytoma. Telaglenastat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as temozolomide, 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. Giving telaglenastat with radiation therapy and temozolomide may work better than surgery, radiation therapy, and temozolomide in treating patients with IDH-mutated diffuse astrocytoma or anaplastic astrocytoma.
This is a Phase 2 study in subjects with WHO Grade III Anaplastic Astrocytoma (G3 astrocytoma) who had progressive disease during first or second line treatment and who have not previously received any BEV or any experimental agents.
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.
This phase I trial studies the side effects and best dose of APX005M in treating younger patients with primary malignant central nervous system tumor that is growing, spreading, or getting worse (progressive), or newly diagnosed diffuse intrinsic pontine glioma. APX005M can trigger activation of B cells, monocytes, and dendritic cells and stimulat cytokine release from lymphocytes and monocytes. APX005M can mediate a direct cytotoxic effect on CD40+ tumor cells.
Glioblastoma is the most common malignant brain tumor in adults. The primary treatment consists of maximal tumor removal followed by radiotherapy (RT) with concomitant and adjuvant temozolomide. Tumor recurrence after chemoradiotherapy has previously been shown to be predominantly within or at the margin of the irradiated volume, but distant failure are not rare, especially in patients with MGMT methylation.Traditionally, RT has been planned based on on planning CT with co-registered postoperative MRI, with the addition of a clinical target volume margin of 2-3 cm to account for infiltrative odema. To better characterize the disease, more specific physiological and/or metabolical markers of tumor cells, vascularization and hypoxia measured on multiparametric MRI as perfusion, diffusion and spectroscopy alongside with PET tracer like Fluoroéthyl-L-tyrosine ([18F]-FET) are now available and suggest that aggressive areas, like uptake of PET tracer and vascularity are present outside areas of contrast enhancement usually irradiated. These informations could be incorporated to optimize the treatment of radiotherapy.
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.
The primary objectives of this study are to determine the maximal tolerated dose (MTD) of PAC-1 in combination with temozolomide in patients with high grade glioma: glioblastoma multiforme (GBM) or anaplastic astrocytoma after progression following standard first line therapy (Component 2), by evaluation of toxicity and tolerability.
The HIT-HGG-2013 trial offers an innovative high-quality diagnostics and science program for children and adolescents >3 years, suffering from one of the following types of high grade gliomas: 1. glioblastoma WHO grade IV (GBM) 2. diffuse midlineglioma histone 3 K27M mutated WHO grade IV (DMG) 3. anaplastic astrocytoma WHO grade III (AA) 4. diffuse intrinsic pontine glioma (DIPG) 5. gliomatosis cerebri (GC) For 1.-3. diagnosis has to be confirmed by neuropathological survey, for 4. and 5. diagnosis has to be confirmed by neuroradiological survey. In addition to standard treatment (radiotherapy and temozolomide chemotherapy) the effect of valproic acid which is traditionally used for treatment of seizure disorder, will be investigated. The aim of the trial will be to investigate whether this drug may increase the effects of radio- and chemotherapy, resulting in a better survival of the treated patients. Scientific studies provided evidence for anti-tumoral effects of valproic acid: the drug seems to be a so-called histondeacetylase inhibitor (HDAC inhibitor), controlling important genetic processes of tumor growth. Studies in cell culture, animals and first clinical trials in adults as well provided evidence for efficacy of valproic acid in the treatment of glioblastoma. Due to this we hope children and adolescents suffering from GBM, DMG, AA, DIPG und GC will benefit from the treatment, too. The aim of the HIT-HGG-2013 trial will be to compare the effects of Valproic acid with data of the HIT-HGG-2007 trial (children and adolescents with same diseases, only treated with simultaneous temozolomide radiochemotherapy). In the present study, it was originally planned to investigate the therapeutic efficiency and safety of valproic acid and the autophagy inhibitor chloroquine, both in addition to temozolomide therapy. Since distribution of Resochin junior (chloroquine phosphate) was terminated, recruitment of new patients was stopped on August 8, 2019. For continuation of the trial, the chloroquine arm was closed but the patients already recruited in this arm will be followed up.
This is a three parallel cohort, open-labeled, non-randomized, multicenter study. All three cohorts will enroll independently.
This randomized phase II clinical trial studies the side effects and how well proton beam or intensity-modulated radiation therapy works in preserving brain function in patients with IDH mutant grade II or III glioma. Proton beam radiation therapy uses tiny charged particles to deliver radiation directly to the tumor and may cause less damage to normal tissue. Intensity-modulated or photon beam radiation therapy uses high-energy x-ray beams shaped to treat the tumor and may also cause less damage to normal tissue. Patients will be more likely to be randomized to proton beam radiation therapy. It is not yet known if proton beam radiation therapy is more effective than photon-based beam intensity-modulated radiation therapy in treating patients with glioma.
