Active clinical trials for "Brain Neoplasms"

This pilot study will assess the safety and feasibility of using an implantable microdevice to measure local intratumor response to chemotherapy and other clinically relevant drugs in malignant brain tumors. The device involved in this study is called a microdevice. The drugs used in this study will only include drugs already used systemically for the treatment of gliomas.

PPROSPERITIT is a prospective clinical study assessing the use of comprehensive molecular profiling to define the best matching targeted and immune treatment for relapsed, refractory or very high risk pediatric CNS tumors.

Introduction: Scalp incision is a powerful nociceptive stimulus that can exacerbate rapid changes in hemodynamic and sympathetic activity. Management of hemodynamic stability is essential in neuro-anesthesia and can be challenging among neurosurgery anesthesiologists. Neurosurgery operations include steps with a lot of painful stimuli such as intubation, insertion of a head-pinning, and craniotomy. A good anesthetic technique can improve hemodynamic responses by reducing the incidence of complications such as intracranial hypertension, bleeding, and longer recovery time. Routine analgesic approach in the intraoperative and postoperative period of supratentorial craniotomy includes the routine use of paracetamol, opioids, scalp nerve block with proven effectiveness, and intravenous ibuprofen, which gives good results by reducing opioid doses in moderate-to-severe pain. Supratentorial craniotomy surgery, which requires tight hemodynamic control, needs effective analgesic methods. Trial design: It is a prospective, randomized controlled, consisting of factorial groups, double-blind study. Participants: This study will be carried out at Ankara University Faculty of Medicine İbni Sina Hospital (Altındağ, Ankara, Turkey) between November 2022 and February 2023. One hundred and two ASA I-III patients with a body mass index (BMI) below 30, aged between 18 and 65, who will undergo elective supratentorial craniotomy due to a brain tumor, are planned to be included in the study. Interventions: The group in which IV ipurofen was administered was named Ibuprofen Group (Group I), the group in which scalp nerve block was applied Block Group (Group), and the group in which IV ibuprofen and scalp nerve block were applied together was named Ibuprofen+Block Group (IB Group). In the premedication unit, 800 mg of ibuprofen in 100 ml of normal saline will be administered to Group I and Group IB, and 100 ml of normal saline without ibuprofen will be administered to Group B as a 30-minute IV infusion. After intubation, a scalp nerve block with 20 ml of 0.5% bupivacaine will be applied to Group B and Group IB, and 20 ml of normal saline will be injected into the block sites in Group I. Objective: The investigators aimed to show the effect of scalp nerve block and IV ibuprofen applications, which are routinely applied, on the optimization of the patient's process from induction to the early postoperative period. In addition, the investigators will examine the comparison of hemodynamic and analgesic effects of scalp nerve block and IV ibuprofen applications under the guidance of pain monitor, and their contribution to reducing opioid consumption, which has side effects such as postoperative nausea/vomiting, slowing of GI motility, respiratory depression. Outcome: The primary endpoint of the study was the differences between the groups in the changes in the patients' nociception level (NoL) index, heart rate, and blood pressure parameters at the time of head-pinning and the first surgical skin incision. Randomization: Randomization of the patients into 3 groups will be carried out using the closed envelope method. Blinding: The patients included in the study and the practicing anesthesiologist do not know which patient is included in which group.

The research aims to develop a novel pathological technology, including rapid whole-mount tissue H&E & IHC staining protocol and high-resolution nonlinear optical microscopy imaging system, to intraoperatively assess brain tumor grade, types and other biological parameters.

This clinical trial evaluates the feasibility of performing oxygen-enhanced magnetic resonance imaging (MRI) to generate hypoxia maps in patients with intracranial tumors. Decreased levels of oxygen (hypoxia) is a hallmark of malignant brain tumors. Chronic hypoxia is a stimulator of blood vessel formation, which is required for tumor growth and spread. Hypoxia also limits the effectiveness of radiation and chemotherapy. MRI is an imaging technique that uses radiofrequency waves and a strong magnetic field rather than x-rays to provide detailed pictures of internal organs and tissues. The administration of inhaled oxygen allows for an increased MRI signal effect size. Oxygen-enhanced MRI may be a non-invasive method that can physiologically estimate tissue hypoxia. With a better understanding of the extent of tumor hypoxia, more effective and patient-specific therapies could be devised to halt malignant tumor growth.

The purpose of the study is to investigate the use of the investigational agent Axumin (fluciclovine-F18) with PET/CT imaging in combination with standard MR imaging to detect remaining or recurrent brain tumor.

The hypothesis of this exploratory clinical trial in patients with high-grade a primary brain tumor who receive chemoradiation is that the PET imaging agents [18F]Fluciclovine and/or [18F]FLT will be a better predictor of tumor response than standard MRI based brain tumor response criteria. When used in conjunction, the two PET agents may be better able to predict tumor aggressiveness and thus overall survival than the use of individual-tracer PET biomarkers. This may eventually lead to improved assessment of response (including time to progression and overall survival) and differentiation of tumor recurrence/progression from treatment effect (pseudoprogression).

An open-label, single institutional phase II trial of losartan in patients with primary and metastatic brain tumors with an individual stepped-wedge, randomized, assessor-blinded, dose-finding design on three indications.

This research study is for Glioblastoma (GBM) patients who will be beginning Optune as part of their clinical care, which is a novel treatment that utilizes - tumor treating fields (TTFields), (aka, electrical therapy), which has shown to improve overall survival in large multi-center trials. As a part of this study, participants will either receive Optune with "standard array mapping" (based on regular contrast enhanced MRI) or an "alternative (more precise) array mapping" based on sophisticated state of the art MRI techniques including "whole brain spectroscopy". Whole brain MRI spectroscopy provides additional metabolic information to map out the full extent of tumor spreading within the brain (far beyond from what is seen on regular MRI), by identifying certain metabolites that are present in cancer cells versus healthy tissue. This study is being performed to show whether alternative array mapping improves treatment outcomes, as opposed to the standard array mapping, by maximizing delivery of TTFields dose, thereby achieving more effective tumor cell killing, decreasing the rate of local recurrence, and improving the overall survival as well as quality of life measures.

This work aims to evaluate neurocognitive performance, daily activity and quality of life and local control among patients with brain metastasis (MBM) ≥ 5 due to solid tumors treated with Stereotactic RadioSurgery (SRS) or Whole Brain RadioTherapy (WBRT). This multicentric randomised controlled trial will be conducted at the Fondazione IOM (Viagrande) in collaboration with REM (Viagrande), Hospital G. Martino (Messina) and Hospital Civico ARNAS (Palermo). It will involve, within 5 years starting from 15 September 2020, the enrollment of 100 patients (50 for each arm) with MBM ≥ 5, age ≥ 18 years, Karnofsky Performance Status (KPS) ≥ 70, life expectancy > 3 months, histological confirmation of primary tumor, with controlled or controllable extracranial disease, baseline Montreal Cognitive Assessment (MoCA) of 20/30, Barthel Activities of Daily Living score 90/100, to be subjected to SRS on each brain lesion by LINAC with monoisocentric technique and non-coplanar arcs (experimental arm) or to WBRT (control arm). The primary endpoints are neurocognitive performance, quality of life and autonomy in daily-life activities variations, the first one assessed by Moca Score and Hopkins Verbal Learning Test - Revised, the second one through the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 Palliative Care (EORTC QLQ-C15-PAL) and Brain Neoplasm (BN-20) questionnaires, the third one through the Barthel Index, respectively. The secondary endpoints are time to intracranial failure, overall survival, retreatments frequency, acute and late toxicities, KPS decrease. It will be considered significant a statistical difference of at least 29% between the two arms (statistical power of 80% with a significance level of 95%). This trial has been approved by the local ethics committee on July 7th 2020 (record 70). Several studies debate what is the predominant factor accountable for the development of neurocognitive decay among patients undergoing brain irradiation for MBM: radiotherapy, especially if extended to the entire brain, or intracranial disease progression? Answer to this question may come from current opportunity, thanks to recent technological advancement, to treat, with significant time savings, improved patient comfort and at the same time minimizing the dose to healthy brain tissue, Multiple Brain Metastasis simultaneously, otherwise attackable only by panencephalic irradiation. The pursuit of a local control rate comparable to that obtainable with WBRT remains the fundamental prerequisite for the aforementioned related assessments.
