Filter by:Growing evidence of Tranexamic Acid (TXA) being used to reduce blood loss and blood transfusions in various guidelines. However, the adverse effects of TXA especially seizure has always been a problem of concern, especially in neurosurgery. Therefore, this study aims to provide a scientific evidence for the safety of TXA in supratentorial meningiomas resection patients.
This Phase 3 open-label single-arm study is designed to investigate the safety, diagnostic performance, and clinical usefulness of Gleolan for the real time detection and visualization of meningiomas during tumor resection surgery. The study is planned to run for 15 months with individual study participation lasting for approximately 2 months.
This research study is studying a drug as a possible treatment for High Grade Meningioma. The drug involved in this study is an immunotherapy drug called pembrolizumab
In this research study the researchers want to learn more about the effects (both good and bad) the study drug selumetinib has on participants with neurofibromatosis type II (NF2) related tumor. The researchers are asking patients with NF2 related tumors to be in the study, because their hearing has decreased and/or their NF2 related tumor has started to grow. The goals of this study are: - Determine if selumetinib will stop NF2 related tumors from growing - Measure the changes in hearing after receiving selumetinib for 6 months. - Determine if selumetinib improves how participants feel (physically and emotionally) and how participants can perform daily activities. - Examine tumor tissue, if available, in a laboratory to see if NF2 related tumors have targets of selumetinib.
This research study is studying a chemotherapy as a possible treatment for Meningiomas (recurrent). The study intervention involved in this study is: --AZD2014 (vistusertib)
This is a prospective observational trial consisting of robotic multisession radiosurgery (CyberKnife ®) for large and medium size and/or located at critical site benign intracranial meningiomas.
In the proposed trial, patients will be administered ribociclib prior to surgical resection of their tumor. Patients will be enrolled in time-intervals sequentially (non-randomized). All patients will be orally-administered 5 doses of LEE011 (900 mg/d) with the final dose occurring at one of 3 intervals before brain tumor resection.
Traditional treatment options for optic nerve sheath meningiomas (ONSM) include observation, surgery and radiotherapy, but to date none of these has become the clear treatment of choice. The role of the radiotherapy remained uncertain because of the concern about radiation related optic neuropathy In the recent past two large series of patients treated with a fractionated stereotactic radiotherapy confirmed these positive experiences in tumour control and greatly reduced the concern about the treatment related toxicity. Under the light of successful meningiomas treatment, radiosurgery, had proposed as a treatment option. Single session, high conformality, frame based radiosurgery systems are seldom if ever proposed as ONSMs treatment due to the known dose tolerance of the optic nerve. The first experience in ONSMs treatment with multisession radiosurgery treatment was quite promising. The aim of the present study is to prospectively evaluate the efficacy and safety of multisession radiosurgery in ONSMs treatment. In order to evaluate multisession radiosurgery 50 patients will be enrolled in the present study. All patients will be treated by using multisession radiosurgery, with 5 fractions of 5 Gy each to a total dose of 25 Gy prescribed to the 75-85% isodose line. Patients were evaluated both for tumor growth control and visual function.
The purpose of this study is to find out what effects, good or bad, the Optune device has on the patient and meningioma. This study is being done because currently there are no proven effective medical treatments for a progressive meningioma that has failed surgery and/or radiation. The study uses an experimental device called Optune. Optune is "experimental" because it has not been approved by the U.S. Food and Drug Administration (FDA) for this type of tumor, although it has been approved for a different type of brain tumor.
Treatment standard for patients with atypical or anaplastic meningioma is neurosurgical resection. With this approach, local control ranges between 50 and 70%, depending on resection status. A series or smaller studies has shown that postoperative radiotherapy in this patient population can increase progression-free survival, which translates into increased overall survival. However, meningiomas are known to be radioresistant tumors, and radiation doses of 60 Gy or higher have been shown to be necessary for tumor control. Carbon ions offer physical and biological characteristics. Due to their inverted dose profile and the high local dose deposition within the Bragg peak precise dose application and sparing of normal tissue is possible. Moreover, in comparison to photons, carbon ions offer an increased relative biological effectiveness (RBE), which can be calculated between 2 and 5 depending on the cell line as well as the endpoint analyzed. First data obtained within the Phase I/II trial performed at GSI in Darmstadt on carbon ion radiotherapy for patients with high-risk meningiomas has shown safety, and treatment results are promising. Therefore, in the current Phase II-MARCIE-Study a carbon ion boost will be applied to the macroscopic tumor (gross tumor volume, GTV) in conjunction with photon radiotherapy to the clinical target volume (CTV) in patients with atypical meningiomas after incomplete resection or biopsy. Primary endpoint is progression-free survival rate, secondary endpoints are overall survival, safety and toxicity.
