1. A Study to Evaluate How Semaglutide Works Compared to Placebo in People with Type 2 Diabetes and Chronic Kidney Disease

   Rochester, Minn.

   The purpose of this study is to evaluate whether or not semaglutide can slow down the growth and worsening of chronic kidney disease in people with type 2 diabetes. Participants will receive semaglutide (active medicine) or placebo ('dummy medicine'). This is known as participants' study medicine - which treatment participants get is decided by chance. Semaglutide is a medicine, doctors can prescribe in some countries for the treatment of type 2 diabetes. Participants will get the study medicine in a pen. Participants will use the pen to inject the medicine in a skin fold once a week. The study will close when there is enough information collected to show clear result of the study. The total time participants will be in this study is about 3 to 5 years, but it could be longer.

2. Obstructive Sleep Apnea Among Somali-Americans

   Rochester, Minn.

   The purpose of this study is to advance the understanding of obstructive sleep apnea as it relates to different ethnic origins as well as sex differences. The investigators will compare Somali patients with known obstructive sleep apnea (OSA) to individuals without OSA, and to individuals of other ethnic/racial origins to determine the risk factors (genetic and/or physiologic) associated with developing cardiovascular diseases. This will help the investigators to understand the unique sleep pathology of individuals of African descent.

3. A Cross-sectional Study Examining Adipose Tissue in Obstructive Sleep Apnea

   Rochester, Minn.

   Studies show that sleep apnea increases the risk of cardiovascular disease and is associated with obesity. However, it is unclear how sleep apnea affects fat tissue. Studies have shown that fat tissue is likely involved in developing cardiovascular disease. The purpose of this study is to see how sleep apnea changes fat tissue.

4. A Study to Evaluate Noninvasive Ultrasound Elastography of Kidney and Lung in Assessment of Volume Status in ICU Patients

   Rochester, Minn.

   The primary purpose of this study is to assess the feasibility of performing lung and kidney and lung ultrasound elastography among patients with critical illness from different etiologies that could be associated with volume overload.

5. A Study of RGLS8429 in Patients With Autosomal Dominant Polycystic Kidney Disease

   Rochester, Minn., Jacksonville, Fla.

   The purpose of ths study is to assess the safety and tolerability of RGLS8429. Addiitionally, to assess the impact of RGLS8429 on ADPKD biomarkers

   Other objectives are o assess the impact of RGLS8429 on height-adjusted total kidney volume (htTKV) and to characterize the pharmacokinetic (PK) properties of RGLS8429 -To assess the impact of RGLS8429 on renal function.

6. In-home Versus In-Clinic Subcutaneous Nivolumab Administration through Connected and Remote Cancer CARE Beyond Walls

   Jacksonville, Fla.

   The purpose of this study is to evaluate the impact of the location of SQ Nivo administration, at the infusion center or in the home, on patient preference and acceptability, safety, patient reported outcomes (PROs), and clinical outcomes.

7. REstrictive versus LIberal Rate of Extracorporeal Volume Removal Evaluation in Acute Kidney Injury (RELIEVE-AKI)

   Rochester, Minn.

   The objective of this study is to evaluate the feasibility of alternative Net Ultrafiltration (UFNET) rate strategies among critically ill adults with acute kidney injury (AKI) and treated with Continuous Kidney Replacement Therapy (CKRT).

    

8. Evaluating Kidney Stones To Determine If They Lead to Kidney Disease

   Rochester, Minn.

   We hypothesize that clinical studies to investigate the role of individual proteins in kidney stone pathogenesis have likely been confounded by an unknown variety of underlying renal pathologies. Therefore, we propose to examine urinary protein crystallization inhibitors in patient populations that have been carefully phenotyped relative to renal stone precursor lesions by direct endoscopic visualization. In collaboration with Project #1, our second major goal is to use these accurately phenotyped patients in order to adapt modern dual-energy CT technology to develop a reliable noninvasive technique to accurately and noninvasively determine stone composition and visualize the earliest kidney stone precursor lesions. Our long-term goal is to improve CT technology so that it can be used to allow large-scale clinical protocols of accurately phenotyped, hence, homogeneous, patient populations.
   
   In a subset we will sample sterile stone, dental plaque, blood and urine samples for detailed microbiome analysis in order to determine the contribution of micro organisms to stone pathogensis.

9. Evaluation of the Total Kidney Volume AI Algorithm

   Rochester, Minn.

   The natural course of autosomal dominant polycystic kidney disease (ADPKD) is highly variable and typically characterized by progressive enlargement of cysts within the kidneys.  ADPKD is a leading cause of end-stage renal disease.  Recently, a new medication called Tolvaptan has been approved by the FDA to slow progression of ADPKD.  Accurate, MR based kidney volume measurements are the best parameter for following the progression of ADPKD, and are suggested be acquired to measure progression and effects of Tolvaptan.  However, making these slice-by-slice volume measurements can be extremely time consuming when done manually.  The purpose of this work is to evaluate an AI algorithm to make the measurements.  The results of the algorithm will be reviewed by a qualified radiologist familiar with the algorithm’s results.  If the radiologist agrees with the results, kidney volumes (left, right and combined) will be recorded for clinical use.  The usage of the algorithm in this setting (with review by radiologist, and manual correction) is a minimal risk to the patients: a failure of the algorithm will have no impact on treatment and errors will be caught and corrected by the QC process. Because the algorithm will not be used solely for diagnosis or inform treatment without the confirmation of the diagnosis by another, medically established diagnostic product or procedure this study constitutes minimal risk to patients. 

10. Study to Evaluate Clinical Complications, Pattern of Kidney Function Decline and Identification of Clinical Variables Related to Progression of Autosomal Dominant Polycystic Kidney Disease

    Rochester, Minn.

    The purpose of this study is to evaluate clinical complications, pattern of kidney function decline and identification of clinical variables related to progression of Autosomal Dominant Polycystic Kidney Disease (ADPKD).
