Filter by:This phase I trial studies the side effects and best dose of ascorbic acid when given together with temozolomide in treating patients with high-grade glioma that has come back. 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. Ascorbic acid contains ingredients that may prevent or slow the growth of high-grade gliomas. Giving temozolomide with ascorbic acid may kill more tumor cells.
This partially randomized pilot phase I trial studies how much sapanisertib reaches the brain tumor and how well it works when given before and after surgery in treating patients with glioblastoma that has grown or come back and requires surgery. Sapanisertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This phase I trial studies the side effects and the safety of injecting HSV1716 (a new experimental therapy) into or near the tumor resection cavity. The injection will be done at the time of surgery. HSV1716 is a virus that has a gene which has been changed or removed (mutated) in such a way that lets the virus multiply in dividing cells of the tumor and kills the tumor cells.
This pilot clinical trial studies advanced magnetic resonance imaging (MRI) techniques in measuring treatment response in patients with high-grade glioma. New diagnostic procedures, such as advanced MRI techniques at 3 Tesla, may be more effective than standard MRI in measuring treatment response in patients receiving treatment for high-grade gliomas.
This molecular biology and phase II trial studies how well imetelstat sodium works in treating younger patients with recurrent or refractory brain tumors. Imetelstat sodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
In the current proposed trial the role of the low-dose WBRT (0.15 Gy) would be to safely treat the microscopic distant GBM cells outside of the high dose RT region and sensitize the gross tumor, while the focal radiation dose (1.85 Gy) to the gross tumor will bring the total tumor dose of 2 Gy per fraction which is the standard of care. Radiotherapy (RT) has been integral in the treatment of GBM since the 1970s when Walker et al. showed that post-operative whole brain radiotherapy (WBRT) offered significant improvements in median survival time, and even more so when given with concomitant BCNU chemotherapy. Ensuing dose escalation studies found the optimal dose to be 60 Gy. Patients could not tolerate escalation to higher doses than 60 Gy with WBRT due to unacceptable toxicity. Even with WBRT of 60 Gy, a huge volume of healthy brain tissue was unnecessarily treated with high-dose radiation; recurrences with WBRT remained overwhelmingly local. Hochberg and Pruitt (1980) found that after WBRT only 3% of recurrences were outside 2 cm of the margins of the primary tumor. With the rise of the CT scan in the 1980s and the MRI in the 1990s, along with subsequent improvements in three-dimensional conformal radiation, partial brain RT (PBRT) became practical since tumor margins could be visualized and irradiated more accurately. - Subsequently, WBRT was shown to provide no survival benefit over PBRT at the same dosage; - thus, the latter took over as the standard of care.
This randomized phase II trial studies how well giving vaccine therapy with or without bevacizumab works in treating patients with recurrent glioblastoma multiforme that can be removed by surgery. Vaccines consisting of heat shock protein-peptide complexes made from a person's own tumor tissue may help the body build an effective immune response to kill tumor cells that may remain after surgery. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them. It is not yet known whether giving vaccine therapy is more effective with or without bevacizumab in treating glioblastoma multiforme.
This is a single-center, open-label, non-randomized, Phase I/IIa study to investigate the safety, tolerability, and antitumor efficacy of AXL1717 (picropodophyllin as active agent formulated in an oral suspension; PPP) in patients with recurrent malignant astrocytomas (glioblastoma, gliosarcoma, anaplastic astrocytoma, anaplastic oligodendroglioma, anaplastic oligoastrocytoma, and anaplastic ependymoma). Patients will be treated for up to 5 cycles. A treatment cycle is defined as 28 days+7 days rest (28+7 days during cycle 1 to 4, and 28 days during cycle 5). The following cycle will not be started until the treatment continuation criteria are fulfilled. Concomitant supportive therapies will be allowed.
The purpose of this study is to investigate the safety and performance of an investigational agent, known as 5-ALA or Gliolan (aminolevulinic acid), that many be useful to a surgeon for visualizing a tumor during surgery. It is also being studied to determine if there are differences in what Gliolan shows a surgeon compared to intraoperative magnetic resonance imaging (MRI)
This study is being done to determine if an investigational cancer treatment called vorinostat combined with fractionated stereotactic radiation therapy (FSRT) is effective in treating recurrent high grade gliomas. The main goal of this research study is to determine the highest dose of vorinostat that can be given to patients with recurrent tumors. The study will also determine the potential side effects and safety of these treatment combinations. Vorinostat is a small molecule inhibitor of histone deacetylase (HDAC). HDAC inhibitors help unravel the deoxyribonucleic acid (DNA) of the cancer cells and make them more susceptible to the treatment with radiation.
