1. Human Blood and Tissues Repository for Neuroscience Research

   Jacksonville, Fla.

   The purpose of this study is to collect adult human blood, cerebrospinal fluid, brain, and spine tissues/fluids at time of surgery in order to conduct future studies of the cellular mechanisms of tissue invasion utilized by brain and spine tumors of the central nervous system (CNS).

2. A Study of the Drugs Selumetinib Versus Carboplatin/Vincristine in Patients With Neurofibromatosis and Low-Grade Glioma

   Rochester, Minn.

   The pupose of this study is to evaluate whether or not selumetinib works just as well as the standard treatment with carboplatine/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, 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. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.

3. A Study to Evaluate Advanced Development of Desorption Electrospray Ionization Mass Spectrometry for Intraoperative Molecular Diagnosis of Brain Cancer

   Jacksonville, Fla.

   The purpose of this study is to explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to identify cancerous versus noncancerous tissue and estimate the percentage of tumor infiltration in tissue biopsies, by monitoring depletion of N-acetylaspartate (NAA) and aberrations of the phospholipid signature of neurological tissue; and to identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and, therefore, differentiate between IDH-mutant and wild-type gliomas.

4. Treatment of Brain AVMs (TOBAS) Study

   Jacksonville, Fla.

   The purpose of this study is to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty.

5. A Study of the Possible Use of a New Imaging Method with Glioma Tumors

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to see if Magnetic Resonance Elastography (MRE) a recently developed imaging technique can be used to characterize and help stage glioma tumors and evaluate response to therapy.

6. Memantine Hydrochloride and Whole-Brain Radiotherapy With or Without Hippocampal Avoidance in Reducing Neurocognitive Decline in Patients With Brain Metastases

   Mankato, Minn., La Crosse, Wis., Eau Claire, Wis., Rochester, Minn., Albert Lea, Minn.

   This randomized phase III trial compares memantine hydrochloride and whole-brain radiotherapy with or without hippocampal avoidance in reducing neurocognitive decline in patients with cancer that has spread from the primary site (place where it started) to the brain. Whole brain radiotherapy (WBRT) is the most common treatment for brain metastasis. Unfortunately, the majority of patients with brain metastases experience cognitive (such as learning and memory) deterioration after WBRT. Memantine hydrochloride may enhance cognitive function by binding to and inhibiting channels of receptors located in the central nervous system. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Using radiation techniques, such as intensity modulated radiotherapy to avoid the hippocampal region during WBRT, may reduce the radiation dose to the hippocampus and help limit the radiation-induced cognitive decline. It is not yet known whether giving memantine hydrochloride and WBRT with or without hippocampal avoidance works better in reducing neurocognitive decline in patients with brain metastases.

7. A Study to Explore if it is Possible to Successfully Obtain Optical Coherence Tomography (OCT) Imaging and Data While Patients Undergo Brain Surgery

   Jacksonville, Fla.

   The goal of this study is to investigate the feasibility of successfully obtaining intra-operative OCT imaging and data during standard brain surgery.

8. A Study to Evaluate Biomarker Target Stimulation

   Rochester, Minn.

   The purpose of this study is to understand how electrical stimulation of the brain can modulate and suppress interictal epileptiform activity as a step on the path to developing new therapies for epilepsy.

9. A Study to Assess Sinus Stenting to Manage Cerebrospinal Fluid Leak

   Rochester, Minn.

   The purpose of this study is to determine whether transverse/sigmoid sinus junction stenting reduces the risk of recurrent cerebrospinal fluid (CSF) leak in patients with idiopathic intracranial hypertension presenting with CSF leak.

    

10. A Study to Evaluate the Feasibility of Intraoperative Microdialysis (tissue sampling) during Neurosurgery for Central Nervous System Malignancies

    Rochester, Minn.
