Below are current clinical trials.

Filter this list of studies by location, status and more.

1. Sponge and Eosinophil Peroxidase (EPO) Staining

   Rochester, Minn.

   Are we able to use the EPO staining technique using the sponge ?

2. Fecal Microbiome Transplant National Registry

   Rochester, Minn.

   The overarching goal of the FMT registry is to expand knowledge and optimize practice in the transplantation of fecal microbiota or other gut-related-microbiota products.

3. Whole Exome Sequencing and Other Emerging Technologies of Endoscopic Ultrasound Cytopathology

   Rochester, Minn.

   The purpose of this research study is to gather information on the feasibility of performing novel molecular analysis on Endoscopic Ultrasound acquired cytologic material and to assess molecular changes in cytology samples to see if that may aid treatment decision planning for future patients.

4. A Study to Evaluate the Progression of Gastrointestinal and Fatigue Symptoms in the Scleroderma Population Seen at Mayo Clinic Arizona

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate the progression of gastrointestinal and fatigue symptoms over time (approximately 5 years) in the scleroderma population seen at Mayo Clinic Arizona.

5. A Study to Assess Gastric Functions

   Rochester, Minn.

   The purposes of this study are to assess gastric motility and emptying with scintigraphy in patients with upper gastrointestinal symptoms, to evaluate the relationship between daily symptoms and GE, motility, and symptoms during a GE study, to assess fasting and postprandial gastric volumes and motility with MRI in patients with upper gastrointestinal symptoms, and to compare gastric motility measured with scintigraphy and MRI.

    

6. Cystic Kidney and Liver Disease Biobank

   Rochester, Minn.

    

   This research study is being done to create a collection of biospecimens (blood, urine, cyst fluid, bile, kidney or liver tissue, etc.) that can be used to facilitate the conduction of research on polycystic kidney and/or liver disease.

7. A Study Establishing a Registry for Endoscopic Suturing (ES)

   Jacksonville, Fla.

   The purpose of this study is to determine patient outcomes (survival, additional endoscopic or surgical procedures) with an endoscopic suturing technique at predetermined intervals compared to historical controls when applicable. To evaluate the effectiveness, safety, and durability of trans-orifice endoscopic suturing therapy for revision of bariatric procedures as well as study the safety, efficacy, and durability of preventative fixation of GI endoprosthetics.

8. Trial of Specific Carbohydrate and Mediterranean Diets to Induce Remission of Crohn's Disease

   Rochester, Minn.

   This protocol is designed to compare the effectiveness of two dietary interventions for patients with Crohn's disease (CD): the Specific Carbohydrate Diet (SCD) and a Mediterranean style diet (MSD) that has been demonstrated to have numerous other health benefits. The two diets will be compared in terms of their ability to resolve both the symptoms and bowel inflammation that characterize this debilitating disease.

9. Transforming Non-Invasive Liver Disease Detection by Magnetic Resonance Elastography

   Rochester, Minn.

   A variety of liver insults lead to pathological changes in liver architecture that culminate in cirrhosis. While invasive liver biopsy was required to detect cirrhosis, the development of magnetic resonance elastography (MRE) has revolutionized our ability to detect liver fibrosis through non-invasive means that involve measurement of liver stiffness. However, a number of pathological findings occur in liver in response to various insults that precede cirrhosis and are clinically important to identify such as steatosis associated with NASH, inflammation associated with viral hepatitis, and congestion associated with cardiac hepatopathy. Detection of such entities provides essential diagnostic, prognostic, and treatment information but yet is not available non-invasively. Recent murine studies from this group of investigators has identified that MRE technology can be adapted to non-invasively detect these conditions. Implementing this into the practice will transform it by obviating the need for invasive liver biopsies in patients suspected of having such forms of suspected liver disease. This will differentiate Mayo from other institutions where such technology is not available.

   An additional aim of this study is to examine the impact of obstructive sleep apnea (OSA) on the pathogenesis of nonalcoholic fatty liver disease (NAFLD), both common comorbidities of obesity. Recent evidence indicates a potential link between OSA and severity of NASH and fibrosis, but the mechanisms of OSA- associated hypoxia on liver disease progression in NAFLD is unclear. This study offers the unique opportunity to analyze this association, as the study population will undergo routine evaluation for OSA, as part as the preoperative work-up prior to bariatric surgery.

10. REFINE: Regorafenib Observational Study in Hepatocellular Carcinoma

    Rochester, Minn.

    The purpose of this observational study is to describe the safety and effectiveness of regorafenib in patients with uHCC under real world practice conditions.
