PQR309 is an oral, dual pan-PI3K (phosphatidylinositol 3-kinase phosphoinositide 3-kinase) and mTOR (mammilian target of rapamycin) inhibitor that penetrates the blood-brain barrier at pharmacodynamically active concentrations. This study plans to evaluate PQR309 in treatment of patients with first progression of glioblastoma.
Chimeric antigen receptor (CAR)-modified T cells can mediate long-term durable remissions in recurrent or refractory CD19+ B cell malignancies, and are a promising therapy to treat glioblastoma, which is the most dangerous and aggressive form of brain cancer. EGFRvIII mutation (epidermal growth factor receptor variant III, EGFRvIII) is the results of tumor specific gene rearrangement naturally happened in about 30% of glioblastoma patients and produces a mutated protein with neo-antigen that is tumor specific and is not expressed in normal human tissues. Therefore, EGFRvIII is an attractive target for CAR T cell therapy. We have constructed a lentiviral vector that contains a chimeric antigen receptor that recognizes the EGFRvIII tumor antigen. A truncated EGFR (tEGFR) which lacks of the ligand binding domain and cytoplasmic kinase domain of wildtype EGFR is incorporated into the CAR vector and is used for in vivo tracking and ablation of CAR T cells in necessary. This pilot study is to determine the safety and efficacy of autologous anti-EGFRvIII CAR T cells in patients with recurrent glioblastoma.
Prospective, open-labeled, multicenter cohort trial for validation of the role of levetiracetam as a sensitizer of temozolomide in the treatment of newly diagnosed glioblastoma patients.
Temozolomide (TMZ) is the chemotherapy drug approved by the FDA to increase survival in glioblastoma (GBM) patients beyond surgical resection and radiation therapy alone. Give its activity in astrocytomas, TMZ is commonly used in grade III anaplastic astrocytoma (AA) as well. Both grade III AA and grade IV GBM are high grade gliomas (HGG). The short half-life of this drug and known oscillations in DNA damage repair make it an ideal candidate for chronotherapy. Chronotherapy is the improvement of treatment outcomes by minimizing treatment toxicity and maximizing efficacy through delivery of a medication according to the timing of biological rhythms within a patient. Chronotherapy has improved outcomes through the reduction of side effects and increase in anti-tumor activity for a variety of cancers, but has never been applied to the treatment of gliomas. Based on the preliminary preclinical data for chronotherapeutic TMZ treatment of intracranial glioma xenografts and the success of chronotherapy in the treatment of other cancers, the invesitgators hypothesize that the timing of TMZ treatment will alter its efficacy and toxicity.
Glioblastoma Multiforme is one of the most common, and unfortunately one of the most aggressive brain tumors in adults with most of the patients recurring and dying of the disease with a median survival of 16 months from diagnosis. Current treatment for patients with newly diagnosed Glioblastoma Multiforme (GBM) is safe maximal surgical resection followed by concomitant conventional Radiotherapy (RT) delivered in 6 weeks + Temozolomide (TMZ) followed by TMZ for 6 to 12 cycles. Recent scientific research has shown that Metformin, a common drug used to treat diabetes mellitus, may improve the results of the treatment in patients with a variety of cancers, such as breast, colon, and prostate cancer. Metformin is an attractive and safe medication to be used in this group of patients because of its very low toxicity. In our center the investigators have been using TMZ for 2 weeks prior to a short course (4 weeks) of RT which equivalent to the standard RT of 6 weeks. Temozolomide is used 2 weeks before RT + TMZ, and this is followed by the 6 to 12 cycles of TMZ. Our results are quiet encouraging with a median survival of 20 months, and acceptable toxicity.
Purposes: The purpose of this phase-II clinical trial is to determine whether or not ADCTA-G, a biologic "vaccine" preparation of patient's own dendritic cell (DC) for glioblastoma multiforme (GBM) treatment, is safe and effective in extending the GBM patient's life. The current conventional multi-modal regimen that may include surgery for tumor resection or biopsy, temozolomide (TMZ) combined chemo-radiotherapy (CCRT) and TMZ adjuvant chemotherapy almost always leaves residual GBM cells to cause fatal recurrence, leading to medium survival period of 8 -15 months and over-all survival rates of about 30% in 2 years and <3% in 5 years after diagnosis/surgery. Thus, in neurosurgical oncology practice, GBM patients in the first 2-year period during and after receiving multi-modal therapy are watched closely for possible GBM tumor recurrence and mortal disease relapse and immediately given palliative treatments and health care, until death. In this phase-II trial, GBM patient participants who receive ADCTA-G "vaccine" adjuvant immunotherapy (added to the conventional multi-modal regimen) will be similarly watched closely by treatments and health care visits at least biweekly from the date of surgery/diagnosis to 24 months, and if alive followed by weekly phone calls and scheduled health care visits at least once every 3 months, up to 72 months after surgery. In the trial protocol, ADCT-G in 10 doses is administered after surgery, over a period of 6 or 8 months, as an adjuvant immunotherapy of the conventional multimodal regimen. Individual ADCTA-G "vaccine" lot of every participant GBM patient is manufactured from patient's own monocyte-derived dendritic cells and the patient's own tumor cell antigens, both of which are prepared by a distinct method of procedures performed within air particle-free barrier good laboratory practice (GLP) facility. Previous phase I/II clinical trial of ADCTA-G "vaccine" immunotherapy administered as an adjuvant to the conventional multimodal regimen, has obtained promising safety and efficacy results for GBM patients in a clinical center. This phase-II clinical trial in China Medical University Hospital-Taichung will employ essentially the same clinical protocols and the same distinct "vaccine" manufacturing method of standard operational procedures (SOP), that is, the conventional multimodal regimen plus adjuvant immunotherapy using personal ADCTA-G "vaccine" lot for every GBM patient participants.
The primary aim of this project is to Compare new msCS and standard DSC-PWI methods in GBM patients undergoing post-operative MRI for monitoring of tumor progression.
Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. Despite intensive research efforts and a multimodal management that actually consists of surgery, radiotherapy and chemotherapy with temozolomide, the prognosis is dismal. The aim of the current observational study is to determine immune phenotypes in individual patients with GBM at the time of diagnosis and to correlate tumor size, location (imaging), tumor properties (isocitrate dehydrogenase - 1 (IDH-1), o6-methylguanine-DNA-methyltransferase (MGMT), epidermal growth factor receptor (EGFR) mutation status, etc.) with clinical data, such as progression free and overall survival, Karnofsky index (progression free survival (PFS),overall survival (OS), Karnofsky score( KFS)), with blood immune phenotypes, biomarkers, and immune histochemical results of tumor infiltrating lymphocytes, macrophages, myeloid derived suppressor cells (MDSC), etc.. The different immunological phenotypes could predict a positive response to specific immunological therapeutic strategies and select the individual therapeutic plan for an individual GBM patient.
The purpose of this study is to determine whether Heat Shock Protein Peptide Complex-96 (HSPPC-96) Vaccine is an feasible and safe treatment for pediatric patients with newly-diagnosed High-Grade Gliomas or recurrent, resectable High-Grade Gliomas and Ependymomas.
