1. Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial - Hemodynamics (CREST-H)

   Rochester, Minn., Jacksonville, Fla.

   We aim to determine whether cognitive impairment attributable to cerebral hemodynamic impairment in patients with high-grade asymptomatic carotid artery stenosis is reversible with restoration of flow. To accomplish this aim CREST-H will add on to the NINDS-sponsored CREST-2 trial (parallel, outcome-blinded Phase 3 clinical trials for patients with asymptomatic high-grade carotid artery stenosis which will compare carotid endarterectomy plus intensive medical management (IMM) versus IMM alone (n=1,240), and carotid artery stenting plus IMM versus IMM alone (n=1,240) to prevent stroke and death). CREST-H addresses the intriguing question of whether cognitive impairment can be reversed when it arises from abnormal cerebral hemodynamic perfusion in a hemodynamically impaired subset of the CREST-2 -randomized patients. We will enroll 500 patients from CREST-2, all of whom receive cognitive assessments at baseline and yearly thereafter. We anticipate identifying 100 patients with hemodynamic impairment as measured by an inter-hemispheral MRI perfusion "time to peak" (TTP) delay on the side of stenosis. Among those who are found to be hemodynamically impaired and have baseline cognitive impairment, the cognitive batteries at baseline and at 1 year will determine if those with flow failure who are randomized to a revascularization arm in CREST-2 will have better cognitive outcomes than those in the medical-only arm compared with this treatment difference for those who have no flow failure. We hypothesize that hemodynamically significant "asymptomatic" carotid disease may represent one of the few examples of treatable causes of cognitive impairment. If cognitive decline can be reversed in these patients, then we will have established a new indication for carotid revascularization independent of the risk of recurrent stroke.

2. A Study of Nervous System Involvement of Coccidioidomycosis at Mayo Clinic Hospital in Arizona

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to gain a better understanding of the presentation, diagnostics, disease course and treatment variations, as well as the factors that may influence features of neuro-invasive Coccidioidomycosis. 

3. A Study of Pyridostigmine in Postural Tachycardia Syndrome

   Rochester, Minn.

   This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure.

4. A Study of Factors That Predispose, Promote, and Perpetuate Post-Traumatic Dizziness

   Rochester, Minn.

   The purpose of this study is to investigate whether recent, groundbreaking discoveries about key pathophysiologic processes that drive chronic dizziness in patients without traumatic brain injury (TBI9,10) are applicable to patients with post-mTBI vestibular disability. We expect the results of this project to have practical clinical and research applications, providing novel data for two future steps:

5. Immune Phenotyping in Amyotrophic Lateral Sclerosis

   Rochester, Minn.

   The goals of this study are to identify biomarkers that allow improved staging or prognosis of the disease, and through the discovery of previously unrecognized immune abnormalities in ALS we aim to eventually identify immune therapies that may provide benefit in ALS.

6. Synucleinopathies

   Rochester, Minn.

   The goals of the study are to prospectively evaluate clinical and laboratory biomarkers of multiple system atrophy and Parkinson’s disease at early clinical disease, at a premotor stage (PAF), and even at a prodromal stage (RBD).

7. A Study to Analyze NMS-03305293 and Temozolomide in Adult Patients with Recurrent Glioblastoma

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

   The objectives of this study are to determine the Maximum Tolerated Dose (MTD) and the Recommended Phase 2 Dose (RP2D) of NMS-03305293 in combination with temozolomide (TMZ) in patients with diffuse gliomas at first relapse (Phase I),  and to determine the antitumor effectiveness of the combination of NMS-03305293 and TMZ in patients with isocitrate dehydrogenase (IDH) wild type glioblastoma at first relapse as measured by the 6-month Progression Free Survival (PFS) rate (Phase II).

8. A Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Anti-tumor Activity of WSD0922-FU

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

   The purpose of this study is to determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of WSD0922-FU in subjects with recurrent glioblastoma, IDH wildtype (GBM), anaplastic astrocytoma, IDH wildtype (AA) and CNS metastases of non-small cell lung cancer (NSCLC).

9. A Study to Evaluate Pluripotent Stem Cell Models for Spinal Muscular Atrophy (SMA) Patients

   Rochester, Minn., La Crosse, Wis., Jacksonville, Fla.

   The purpose of this study is to perform RNA sequencing on induced pluripotent stem cells (iPSC).  By comparing the gene expression of motor neurons derived from iPSC cells of phenotypically discordant Spinal Muscular Atrophy (SMA) sibling pairs and individual cases of SMA, we hope to identify potential protective gene modifiers of SMA.   Identifying protective gene modifiers will increase our understanding of the molecular pathogenesis of SMA.

10. A Long Term Study of Molecular and Structural Imaging in Atypical Alzheimer's Disease

    Rochester, Minn.

    The purpose of this study is to learn more about amyloid and tau burden in the brain of patients with Atypical Alzheimer's Disease and how that burden may change over a two-year period.
