Filter by:This is a pilot or feasibility study to test the study plan and to find out whether enough participants will join a larger study and accept the study procedures. Eligible participants (adults with newly diagnosed glioblastoma multiforme [GBM] and had a good tumour resection [>= 70% of initial tumour volume] and plan to receive 6 weeks of chemoradiation followed by up to 6 months of chemotherapy) are asked to donate their own stool samples at 4 different time points during their treatment course. Participants will also complete a 7-day diet diary and two questionnaires about their health-related quality of life. Glioblastoma multiforme (GBM) is the most common and aggressive form of primary brain cancer in adults. The current best evidence-proven treatment for GBM includes maximum safe tumour resection, brain radiation over a 6-week period given with chemotherapy pills called temozolomide (Brand name: Temodal or Temodar), followed by approximately 6 months / cycles of temozolomide. Despite these treatments, the average life expectancy is generally less than 2 years. Researchers are recognizing that the immune system has an important role in directing the effectiveness of chemotherapy, radiation, and newer therapies such as immunotherapies. Some immunotherapies have been quite successful in improving cancer control and survival in other cancers like melanoma (an aggressive skin cancer), but when these drugs were given to patients with GBM, there appeared to only be a small effect. Therefore, finding ways to make existing and new treatments work better should be a priority. Recent scientific studies have shown that the bacteria that make up our stool, often referred to as the gut microbiome, play a major role in regulating the immune system. For example, researchers were able to make patients with melanoma who previously did not respond to immunotherapy become responsive to the treatment after receiving a stool transplant from responders to immunotherapy. This provides proof of concept that we could modify the body's immune environment to favour cancer killing by changing a person's gut bacteria environment. The role of the gut bacteria in patients with brain cancer is poorly understood as very few studies have been published about it in this population. We believe that understanding the composition of the gut microbiome and how it relates to the effectiveness and side effects of treatments in GBM patients will be an important first step to understanding how we can modify the gut microbiome to improve outcomes for patients living with GBM.
Primary brain cancer kills up to 10,000 Americans a year. These brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months. Glioma is the most common form of primary brain cancer, afflicting approximately 7,000 patients in the United States each year. These highly malignant cancers remain a significant unmet clinical need in oncology. The investigators have completed a Phase I clinical trial that has shown that Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (BV) is safe up to a dose of 15mg/kg in patients with recurrent malignant glioma. Additionally, the investigators have shown in a recently completed Phase I/II clinical trial, that SIACI BV improves the median progression free survival (PFS) from 4-6 months to 11.5 months and overall survival (OS) from 12-15 months to 23 months in patients with newly diagnosed GBM. Therefore, this two-arm, randomized trial (2:1) is a follow up study to these trials and will ask simple questions: Will this repeated SIACI treatment regimen increase progression free survival (PFS-primary endpoint) and overall survival (OS-secondary endpoint) when compared with standard of care in patients with newly diagnosed GBM? Exploratory endpoints will include adverse events and safety analysis as well as quality of life (QOL) assessments. The investigators expect that this project will provide important information regarding the utility of repeated SIACI BV therapy for newly diagnosed GBM and may alter the way these drugs are delivered to our patients in the near future.
This phase I/Ib trial tests the safety, side effects, and best dose of mycophenolate mofetil in combination with temozolomide and/or radiation therapy (standard of care) in treating patients with glioblastoma. Mycophenolate mofetil is an immunosuppressant drug that is typically used to prevent organ rejection in transplant recipients. However, mycophenolate mofetil may also help chemotherapy with temozolomide work better by making tumor cells more sensitive to the drug. The purpose of this trial is to determine if mycophenolate mofetil combined with temozolomide can stop glioblastoma.
Tailored approaches targeting crucial oncogenes and pathways have shown successful results in a number of cancer types and offer exciting perspective in neuro-oncology. IDH (Isocitrate dehydrogenase) wild-type (IDHwt) glioblastoma (GBM) (10%) present a unique and homogenous energetic metabolism which is specifically dependent on the oxidative phosphorylation (OXPHOS) rather than on the aerobic glycolysis. OXPHOS+ IDHwt GBMs overexpress mitochondrial markers and can be specifically inhibited by mitochondrial inhibitors in vitro and in vivo. Metformin is an oral inhibitor of mitochondrial complex I and is a widely used drug in diabetic and non-diabetic patients, safe and well tolerated in association with radiotherapy and chemotherapy. Basing on drastic effect, the investigators have observed in vivo (reduction of >50% of tumor growth) and hypothesize that metformin could be specifically efficient to treat up-front patients affected by OXPHOS+ GBM, in association with the standard first-line treatment with radiotherapy and temozolomide (RT-TMZ). The investigators set up a dedicated molecular analysis including RNA assay and expression of OXPHOS markers for formalin-fixed paraffin-embedded tumors (FFPE), which allows to detect OXPHOS+ GBM at diagnosis. Here a phase II, open label, non-randomized multicenter trial including five French neurooncology centers (H. Foch-Suresnes, Pitié-Salpêtrière-Paris, Saint Louis-Paris, Lyon, Marseille) and one in Italy (Istituto Besta, Milan) is proposed. Newly diagnosed IDH wild-type GBM patients with the OXPHOS+ signature will be eligible for inclusion in this trial. The investigators expect to screen 640 patients and to include 64 patients over a period of 24 months with 24 months of follow-up.
Paclitaxel is among the most active agents against glioblastoma in preclinical models. However, its clinical use has been hampered by the blood-brain barrier (BBB). In this trial we will implant a novel device with 9 ultrasound emitters allowing to temporarily and reversibly open the BBB immediately prior to chemotherapy infusion with albumin-bound paclitaxel. In the phase 1 component, increasing doses of chemotherapy will be delivered as long deemed safe based on the prior patient not experiencing severe toxicity. Once the the recommended dosing has been established, carboplatin will be added to the regimen and additional patients will be treated in order to better evaluate the antitumor efficacy of this novel treatment. The device will be implanted at the time of surgical resection of the recurrent tumor. During that procedure and when feasible, a first test dose of the chemotherapy will be administered in the operating room after sonication (procedure of activating ultrasound and opening the BBB) and tissue concentrations in different parts of the resected tumor will be measured. In select patients, the sonication procedure may occur immediately after the test dose of chemotherapy is administered. The objectives of this trial are to establish a safe and effective dose of albumin-bound paclitaxel, to demonstrate that the opening of the BBB increases chemotherapy concentration in the tumor, and to estimate how effective this treatment is in reducing the tumor burden and prolonging life.
This phase I trial studies the side effects and best dose of WSD0922-FU for the treatment of glioblastoma, anaplastic astrocytoma, or non-small cell lung cancer that has spread to the central nervous system (central nervous system metastases). WSD0922-FU is a targeted treatment which blocks the EGFR protein - a strategy that has led to a lot of benefit in patients with many different cancers. WSD0922-FU may also be able to get into cancers in the brain and spinal cord and help patients with brain and spinal cord cancers. Funding Source - FDA OOPD
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).
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.
