1. A Study to Collect Blood DNA Samples from Patients with Clinically Diagnosed Alzheimers Disease, Lewy Body Disease, and Frontotemporal Degeneration

   Rochester, Minn.

   The purpose of this study is to collect blood samples for DNA analysis from patients clinically diagnosed with Alzheimers disease, Lewy Body disease, and Frontotemporal degeneration.

2. Investigating the Genetic and Phenotypic Presentation of Ataxia and Nucleotide Repeat Diseases

   Jacksonville, Fla.

   The purpose of this study is to create a repository for cerebellar ataxia and nucleotide repeat diseases in order to fully investigate the genetic and phenotypic presentations of both.

3. ALSENLITE: Senolytics for Alzheimer's Disease

   Rochester, Minn.

   The purpose of this study is to measure target engagement in cerebrospinal fluid (CSF) and blood, and to establish the feasibility and safety of Dasatinib plus Quercetin treatment in adults with early stage but symptomatic Alzheimer's Disease (AD) to inform and select the best blood, CSF, urine, and other analyses to conduct in banked samples from a larger Phase 2b clinical trial.

4. A Study to Establish a Parkinson’s Disease (PD) Cohort using the Parkinson’s Progression Markers Initiative (PPMI)

   Scottsdale/Phoenix, Ariz.

   The Parkinson Progression Marker Initiative (PPMI) is a study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson’s disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability.

5. 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.

6. A Study to Evaluate Droperidol Use in the Emergency Department and the Effect on QTc

   Rochester, Minn.

   The purpose of this study is to study the length of the QTc interval in patients receiving the standard of care dose of intravenous droperidol for headache or migraine, nausea, pain, and indications other than agitation over 30 minutes.

7. A Study to Assess Medtronic Deep Brain Stimulation (DBS) Therapy for Epilepsy Post-Approval (EPAS)

   Rochester, Minn.

   The purpose of this post-approval study is to further evaluate the long-term safety and effectiveness of Medtronic DBS therapy for epilepsy on seizure reduction in newly implanted participants through 3 years of follow-up in different geographic populations.

8. 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.

9. 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].

10. 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.
