Active clinical trials for "Brain Neoplasms"

The investigators hypothesize that the rate of radiologically complete resections of contrast-enhancing brain tumors following surgeries aided by use of 5-ALA induced fluorescence guidance and use of an intraoperative ultra-low field MRI is higher compared to surgeries aided by 5-ALA induced fluorescene alone.

Trial Hypothesis: Acute, progressing lethal neurooncological process can be transferred into chronic and non-lethal, the survival rates and life quality can be improved by of control of tumor cells (TCs) quantity and targeted regulation of effector functions of tumor stem cells (TSCs). Brief Description: The first line therapy of brain metastases of breast cancer (BMBC) involves allogeneic haploidentical hematopoietic stem cells (HSCs), dendritic vaccine (DV) and cytotoxic lymphocytes (CTLs). TCs and TSCs are isolated from BMBC sample. Dendritic cells are isolated from peripheral blood mononuclear cells and cultured. Tumor sample provides tumor specific antigens to prepare DV. CTLs are obtained from peripheral blood after DV administrations. HSCs are harvested from closely related donor after granulocyte-colony-stimulating factor (G-CSF) administration. Allogeneic HSCs are administered intrathecally 5 times every 2 weeks, at day 1, 14, 28, 42, 56. DV is given 3 times every 2 weeks (day 14, 28, 42) subcutaneously in four points. CTLs are administered every 2 weeks for 3 months, then 3 times every 1 month intrathecally. Six months after the therapy completion, the efficiency is evaluated and the cohort demonstrating efficiency continues the therapy, while cohort demonstrating no efficiency is transferred to active comparator arm. Second line therapy involves DV with recombinant proteins, CTLs and autologous HSC with modified proteome. Autologous HSCs are mobilized by G-CSF. Carcinogenesis-free intracellular pathways of signal transduction able to respond to targeted regulation of therapeutic cell systems with specific properties, are detected in TSCs using complete transcriptome profiling of gene expression, proteome mapping and profiling of proteins, bioinformation and mathematical analysis and mathematical modeling of protein profiles. To find key oncospecific proteins in TSCs and TCs, the targets for TSCs regulation are detected, as well as protein ligands able to regulate reproductive and proliferative properties of TSCs. Using these data of TCs and TSCs proteins, the cell preparations to initiate adoptive immune response are prepared: DV loaded with recombinant proteins analogous to key tumor antigens, CTLs and autologous proteome-based HSCs. Autologous HSCs, DV and CTLs are administered as in the first line therapy.

This study evaluates hippocampus-sparing whole-brain radiotherapy with simultaneous integrated boost for patients with multiple brain metastases from non-small cell lung cancer. The primary endpoint is intracranial progression free survival, and secondary endpoints are verbal neurocognitive function, overall survival, adverse events according to CTCAE v4.03, and quality of life.

The purpose of this study is to evaluate the effects on neurocognitive function of whole-brain radiotherapy (WBRT) with/without TMZ concurrent chemotherapy or avoidance of hippocampus for patients of brain metastases, as well as the feasibility and risk of avoidance of hippocampus during whole-brain radiotherapy.

Patients undergoing intracranial procedures may experience severe hypertension and tachycardia due to intracranial hypertension and to increased release of adrenaline. Preventing perioperative sympathetic activity is of great importance. A common technique is using b-blockers like esmolol, which effectively block perioperative hemodynamic changes during intracranial surgery. A2 agonists, like Dexmedetomidine-Dex are now being used as a component of a balanced anesthesia during neurosurgical procedures. This study aimed to evaluate whether esmolol or dex attenuates perioperative changes in patients undergoing elective craniotomy with fast track neuroanesthesia.

This Phase 3, open-label, triple arm study aims to evaluate the overall survival (OS) of fotemustine versus the combination of ipilimumab and fotemustine or the combination of Ipilimumab and nivolumab in patients with metastatic melanoma with brain metastasis.

The investigators propose a new treatment strategy of fractionated stereotactic radiosurgery with concurrent bevacizumab for brain metastases. This phase I dose-escalation study is to establish the feasibility of this strategy and find the recommended doses.

The purpose of this pilot study is to test new magnetic resonance imaging (MRI) acquisition and processing techniques on primary brain tumor patients. The objectives are to improve image-guided radiation therapy (IGRT) planning (first part of the study) and treatment monitoring (second part).

RATIONALE: Radiation therapy uses high-energy x-rays to kill 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 or by stopping them from dividing. It is not yet known whether radiation therapy is more effective when given alone or together with temozolomide in treating brain metastases secondary to breast cancer. PURPOSE: This randomized phase II trial is studying how well radiation therapy given together with temozolomide works compared with radiation therapy given alone in treating women with brain metastases and breast cancer.

Bradmer Pharmaceuticals, Inc. (Bradmer) is requesting approval to study the safety of Neuradiab® when combined with Bevacizumab (Avastin) therapy given at a minimum of 30 days after Neuradiab administration in patients with a first or second recurrence of glioblastoma multiforme (GBM), in an attempt to manage life threatening recurrence of Grade IV malignant glioma.
