Active clinical trials for "Glioblastoma"

This phase II/III trial studies how well vocimagene amiretrorepvec (Toca 511) and extended release flucytosine (Toca FC) work when added to the usual treatment (temozolomide and radiation therapy) in treating patients with newly diagnosed glioblastoma. Toca 511 is a live virus that has been built to carry a gene into tumor cells. This gene carries instructions that cause the tumor cells to turn Toca FC, typically used to treat fungal infections, into a drug that may kill the tumor cells. Drugs used in chemotherapy, 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving Toca 511 and Toca FC in addition to the usual treatment (temozolomide and radiation therapy) may help shrink or stabilize cancer or extend the life of patients with newly diagnosed glioblastoma.

Despite the success of anti-angiogenic therapy in multiple treatment settings, a fraction of patients are refractory to vascular endothelial growth factor (VEGF) inhibitor treatment while the majority of patients will eventually develop evasive resistance and exhibit disease progression while on therapy. It is proposed that mesenchymal-epithelial transition factor (c-MET) and its ligand hepatocyte growth factor (HGF or scatter factor) contribute significantly to VEGF inhibitor resistance such that combining a c-MET inhibitor with a VEGF inhibitor will provide additional clinical activity compared to VEGF inhibitor alone. This hypothesis will be tested using the cMET/ALK inhibitor, crizotinib, in combination with individual VEGF inhibitors. Three combinations will be prioritized, namely crizotinib plus axitinib, crizotinib plus sunitinib and crizotinib plus bevacizumab, with a fourth combination, crizotinib plus sorafenib to be tested only if crizotinib does not combine with either axitinib and/or sunitinib.

Patients with specific metastatic cancers who failed prior therapeutic regimes will be treated with NDV for at least a year or until disease progression. The study will measure progression-free disease and posits that it will be extended.

The primary objective of this study is to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of dasatinib when combined with protracted, daily temozolomide (TMZ). Secondary objectives are: To further evaluate the safety and tolerability of dasatinib plus protracted, daily TMZ; 2. To evaluate the pharmacokinetics of dasatinib when administered with protracted, daily TMZ among recurrent malignant glioma patients who are on and not on CYP-3A enzyme inducing anti-epileptic drugs (EIAEDs); 3. To evaluate for anti-tumor activity with this regimen in this patient population.

This research study is studying a combination therapy as a possible treatment for recurrent glioblastoma (GBM), a brain tumor that is growing or progressing despite earlier treatment. This study will involve participants with recurrent glioblastoma at their first relapse enrolled in two arms including patients who require reoperation and patients not requiring surgery. This research study involves a combination of two drugs: Pembrolizumab (MK3475) Abemaciclib (LY2835219)

The main purpose of this study is to find out the highest possible dose of maprotiline that can be given safely in combination with temozolomide and tamoxifen.

PROPHETIC GBM - Predicting response patterns to treatment in Glioblastoma (GBM) oncology patients based on host response evaluation during anti-cancer treatments

Purpose and Objective: To compare the effects of either an abbreviated or protracted taper of dexamethasone on functional capacity in newly diagnosed glioblastoma multiforme (GBM) patients. To compare neurocognitive function in newly diagnosed GBM patients receiving either an abbreviated or protracted taper of dexamethasone. To compare skeletal muscle strength in newly diagnosed GBM patients receiving either an abbreviated or protracted taper of dexamethasone. To examine the association between functional capacity and neurocognitive function and patient-reported measures (i.e. quality of life, fatigue, etc.) in newly diagnosed GBM patient on either an abbreviated or protracted taper of dexamethasone. To examine the association between functional capacity and neurocognitive function and body composition measures (body-mass index, etc.) in newly diagnosed GBM patient on either an abbreviated or protracted taper of dexamethasone. To examine the association between functional capacity and neurocognitive function and biochemical metabolic measurements in newly diagnosed GBM patient on either an abbreviated or protracted taper of dexamethasone. All study endpoints will be assessed at three timepoints as follows: (1) initial assessment after surgery in the hospital, (2) second assessment at initial clinical visit at the Preston Robert Tisch Brain Tumor Center (PRT-BTC) at Duke, approximately 1 week post-operatively, and (3) third assessment at second clinical visit in the PRT-BTC at Duke, approximately 10 weeks post-operatively and after completion of radiotherapy. An additional fourth assessment will be obtained at 4 weeks post-operatively if the subject is undergoing radiotherapy here at Duke.

Hypothesis: The central hypothesis underlying the proposed research study is that FET-PET will predict durable benefit in patients receiving anti-angiogenic benefit for presumed recurrent GBM (i.e. progression-free survival and overall survival). We have defined one primary specific aim, for which we expect to obtain definitive results, and two secondary aims, under which we plan to generate preliminary data to support a future, larger project.

18F-FDOPA PET is expensive. It is mandatory therefore to assess its impact on the management of patients with high-grade gliomas in order to provide medico-economic justification for its use. The article by the UCLA group showed that 18F-FDOPA modified 41% of management decisions for patients with brain tumors (Walter JNM 2012). However, this study comprised 58 patients, combined primary and recurring tumors, and was based on questionnaires sent out to referring physicians. A targeted study is needed, therefore, to make a prospective multicenter assessment of the contribution of this technique in the context of high-grade glial tumors and neurooncology MCCs.
