1. Image-based Mapping Of Brain Tumors

   Scottsdale/Phoenix, Ariz., Rochester, Minn.

   The purpose of this study is to combine MRI images with histologic and genetic analysis of cancer (from blood and tissue samples) to improve the overall accuracy of diagnosis and effectiveness of cancer treatment.

    

2. Detection of Vascular and Inflammatory Plasma Biomarkers in Patients Diagnosed with Obstructive Sleep Apnea and MRI-defined Cerebral Small Vessel Disease

   Jacksonville, Fla.

   The purpose of this study is to evaluate plasma biomarkers of vascular function and inflammation in patients with newly-diagnosed Obstructive Sleep Apnea (OSA) and pre-existing imaging evidence of Cerebral Small Vessel Disease (CSVD).

3. A Study Of Clonal Hematopoiesis (CH) And Hematological Toxicity After Cancer Treatment

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

   The overall objective of this project is to combine robust clinical data (e.g. prior chemotherapy or radiation exposure, cumulative radiotheranostic dose) with geneticclonal abnormalities (blood-based CHIP panel) in studying the predisposing risk factors for developing hematological toxicity including t-MN in radiotheranostic treated solid tumor patients.

4. Actinium Therapy For Late-stage Aggressive Sarcomas

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

   The goal of this clinical trial is to learn about the safety of drug [Ac225]RTX-2358 and the diagnostic imaging agent [Cu64]LNTH-1363S. Additionally Ratio Therapeutics will learn if [Ac225]RTX-2358 drug is effective in treating advanced sarcoma.

   The main questions the study aims to answer in Phase/Part 1 of the trial are:

   • Is [Ac225]RTX-2358 tolerable or does it cause toxicities (medical problems) in patients.

   • What is the most tolerable dose of [Ac225]RTX-2358

   • Does the treatment show effectiveness on advanced sarcoma

   Participants will:

   • Take drug [Ac225]RTX-2358 once every 8 weeks (4 cycle target; 6 cycle maximum) over a period of 12 months

   • Visit the clinic three times for the first week of cycle one, then once a week for the remaining 7 weeks of cycle 1 for check-ups and tests.

   • For cycles 2-6: patient will visit the clinic once every 2 weeks for checkups and tests

   • Remain in long term follow-up for a period of four additional years

5. A Study Of Secondary Patellar Resurfacing Following Primary Total Knee Arthroplasty

   Rochester, Minn.

   The purpose of this study is to address these gaps by evaluating the rate, indications, and outcomes of secondary patellar resurfacing in patients who underwent primary TKA without initial patellar resurfacing.

6. A Study Of Change In Imaging Biomarkers Of Dementia With Lewy Bodies (DLB) And Associations With Cognitive And Functional Decline

   Jacksonville, Fla., Rochester, Minn.

   Longitudinal Imaging Biomarkers of Disease Progression in Prodromal and Overt DLB

7. A Study to Evaluate Ultrasound Microvessel Imaging

   Rochester, Minn.

   The purpose of this study is to find out the optimal acquisition parameters for ultrasound microvessel imaging in healthy volunteers. 

8. A Study of Ticagrelor in the Upstream Setting for Non-ST-Segment Elevation Myocardial Infarction

   Jacksonville, Fla.

   The purpose of this study is to establish a registry that will address the data gap regarding the course of NSTEMI (Non-ST-Elevation Myocardial Infarction) between ED (Emergency Department) arrival and diagnostic angiography in detail, by characterizing and following the ED and peri-ED use of advanced OAP (Oral Anti-Platelet) agents. In addition to exploring ED treatment patterns and success of both ischemic and bleeding risk stratification prior to definition of the coronary anatomy, data generated via the UPSTREAM registry will allow plausible attribution of ischemic and bleeding outcomes to pre-catheterization antiplatelet therapy in the management of NSTEMI. This registry further seeks to demonstrate that contemporary use of upstream ticagrelor is associated with an economically-sound utilization of hospital resources, and smooth transition of care into the outpatient, secondary prevention setting for the first 30 days after hospitalization. Finally, it will allow characterization of patient selection factors and processes for ticagrelor vs alternative OAP agents, carrying out that descriptive comparison through discharge. Patients transferred in to an UPSTREAM hospital are eligible for inclusion, but the timing for OAP agent administration and diagnostic catheterization begin with ED care at the first hospital.

9. MR Elastography of Hydrocephalus

   Rochester, Minn.

   We are doing this research study to develop and test the effectiveness of a new imaging technique called magnetic resonance elastography (MRE). This technique measures the stiffness (mechanical properties) of the brain and cerebral spinal fluid.

10. Medical and Resource Facilitation Intervention After Traumatic Brain Injury (MRFI)

    Rochester, Minn.

    The purpose of this study is to determine if there are changes in mild traumatic brain injury (mTBI) and/or repetitive head impacts (RHI) detectible with multiparametric MR Elastography (MRE). The hypothesis is that multiparametric MR Elastography will detect changes in the mechanical properties of human head tissues in patients following head traumas.
