1. Primary Tumor Research And Outcome Network (PTRON) Registry

   Rochester, Minn.

   The purpose of this registry is to collect clinical, diagnostic, and therapeutic data specific for primary spinal column tumor patients, and evaluate it to understand the predictive factors which influence survival, local recurrence, adverse events, perioperative morbidity, and health related quality of life.

2. A Study Of Sonodynamic Therapy With SONALA-001 And Exablate 4000 Type 2.0 In Subjects With Progressive Or Recurrent Glioblastoma Multiforme (RGBM)

   Rochester, Minn.

   The purpose of this study is to characterize the safety, dose limiting toxicities (DLTs), maximum tolerated dose (MTD), maximum administered dose (MAD) and recommended phase 2 dose (RP2D) for future study after treatment with SONALA-001 in combination with MRgFUS in subjects with progressive or rGBM.

3. Cognitive Advancement and Recovery in VNS-Rehabilitation (CARE)

   Rochester, Minn.

   The purpose of this study is to investigate whether VNS therapy leads to any changes in the cognitive functions of individuals who have survived a stroke.

4. Arizona Alzheimer’s Disease Research Center (ADRC-001)

   Scottsdale/Phoenix, Ariz.

   There is evidence that neurodegenerative changes precede clinical symptoms in Alzheimer’s disease by two decades (Villemagne et al, 2013). Early detection is critical for development of interventions to halt, slow, or even reverse these pathological processes. The promise of plasma biomarkers to identify early pathology is growing rapidly (Palmqvist et al, 2020), however it is likely that multiple converging biomarkers will be necessary to identify the earliest pathological changes, as subtle differences from healthy controls may fall within the margin of error for any given single biomarker measure. Here we propose that the evaluation of speech and language for both baseline (cross-sectional) and longitudinal changes (within-participant) may add significant value to early pre-clinical pathological changes in MCI and AD. This is bolstered by emerging evidence of the relationship between language characteristics and amyloid burden (Verfaillie et al, 2019) and the large literature that characterizes language-use differences and deficits across the spectrum of cognitive decline (e.g., Mueller et al, 2018). We propose to add a series of in-clinic language elicitation tasks that allow for automated assessment of relevant speech and language domains and to validate these measures cross-sectionally and longitudinally relevant to neuropsychological, blood, and PET biomarkers.

5. EMU

   Jacksonville, Fla.

   The purpose of this study is to demonstrate haemorrhage detection sensitivity >80% and specificity >80%.

6. Testing the Addition of an Anti-cancer Drug, Selinexor, to the Usual Chemotherapy Treatment (Temozolomide) for Brain Tumors That Have Returned After Previous Treatment

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of phase 1 of this trial is to determine the maximum tolerated dose of temozolomide followed by selinexor in recurrent glioblastoma patients as determined by dose-limiting toxicities [DLTs] and the total toxicity profile.

   The purpose of phase 2 of this trial is to evaluate the effectiveness of sequentially administering temozolomide and selinexor in recurrent glioblastoma as determined by progression-free survival [PFS].

7. Magnetic Resonance Elastography of Dementia

   Rochester, Minn.

   The purpose of this study is to develop and test the effectiveness of an investigational imaging technique called magnetic resonance elastography (MRE) to measure the stiffness (mechanical properties) of tissues.

8. 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.

9. 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).

10. A Study to Evaluate Sex and Gender in Multiple System Atrophy

    Rochester, Minn.

    The primary purpose of this study is to understand the influence of sex and gender on pathophysiologic mechanisms of neurodegeneration in Multiple System Atrophy (MSA) in order to determine sex-specific hormonal factors associated with onset of symptoms in MSA.
