Filter by:This phase I/II trial tests the safety, side effects, and best dose of selinexor given in combination with standard radiation therapy in treating children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG) with a genetic change called H3 K27M mutation. It also tests whether combination of selinexor and standard radiation therapy works to shrink tumors in this patient population. Glioma is a type of cancer that occurs in the brain or spine. Glioma is considered high risk (or high-grade) when it is growing and spreading quickly. The term, risk, refers to the chance of the cancer coming back after treatment. DIPG is a subtype of HGG that grows in the pons (a part of the brainstem that controls functions like breathing, swallowing, speaking, and eye movements). This trial has two parts. The only difference in treatment between the two parts is that some subjects treated in Part 1 may receive a different dose of selinexor than the subjects treated in Part 2. In Part 1 (also called the Dose-Finding Phase), investigators want to determine the dose of selinexor that can be given without causing side effects that are too severe. This dose is called the maximum tolerated dose (MTD). In Part 2 (also called the Efficacy Phase), investigators want to find out how effective the MTD of selinexor is against HGG or DIPG. Selinexor blocks a protein called CRM1, which may help keep cancer cells from growing and may kill them. It is a type of small molecule inhibitor called selective inhibitors of nuclear export (SINE). Radiation therapy uses high energy to kill tumor cells and shrink tumors. The combination of selinexor and radiation therapy may be effective in treating patients with newly-diagnosed DIPG and H3 K27M-Mutant HGG.
This phase II trial studies the effect of immunotherapy drugs (ipilimumab and nivolumab) in treating patients with glioma that has come back (recurrent) and carries a high number of mutations (mutational burden). Cancer is caused by changes (mutations) to genes that control the way cells function. Tumors with high number of mutations may respond well to immunotherapy. Immunotherapy with monoclonal antibodies such as ipilimumab and nivolumab may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Giving ipilimumab and nivolumab may lower the chance of recurrent glioblastoma with high number of mutations from growing or spreading compared to usual care (surgery or chemotherapy).
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). The investigators have shown in a previous phase I trial that a single Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (up to 15mg/kg) is safe and effective in the treatment of recurrent GBM. Therefore, this phase I/II clinical research trial is an extension of that trial in that the investigators seek to test the hypothesis that repeated dosing of intra-arterial Bevacizumab is safe and effective in the treatment of recurrent malignant glioma. Additionally the investigators will analyze if a combination with IA Carboplatin will further improve the treatment response. By achieving the aims of this study the investigators will also determine if IV therapy with Bevacizumab with IV Carboplatin should be combined with repeated selected intra-arterial Bevacizumab plus Carboplatin to improve progression free and overall survival. The investigators expect that this project will provide important information regarding the utility of repeated SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to the investigators patients in the near future.
