Below are current clinical trials.

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

1. Achalasia Patient Reported Outcomes

   Rochester, Minn.

   Patients that are either scheduled to undergo or have undergone an achalasia procedure at the Mayo Clinic Rochester are asked to participate. The purpose of this study is to gather information and determine if one of these procedures is superior to the other.

2. Prostaglandin Levels in Pancreatic Cyst Fluid, Pancreatic Juice, and Resected Pancreatic Cysts

   Rochester, Minn.

   The purpose of this study is to determine whether COX-2 enzyme activity in pancreatic cystic neoplasms is sufficient to justify a chemoprevention study.

3. MRI to Assess Fibrosis in Eosinophilic Esophagitis Patients

   Rochester, Minn.

   Can an MRI detect and monitor the inflammatory and fibrotic possess in patients with Eosinophilic Esophagitis

4. Transforming Non-Invasive Liver Disease Detection by MRE: The Hepatogram

   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.

5. Circulating Tumor Cells in Patients with Cholangiocarcinoma

   Rochester, Minn.

   The overall goal of this research is to measure the circulating tumor cell in the peripheral blood and investigate the association between circulating tumor cell level and tumor characteristics and prognosis.

    

6. A Study to Evaluate the Safety, Tolerability, and Clinical Benefit of AK002 in Adult Patients with Mast Cell Gastritis and/or Gastroenteritis

   Rochester, Minn.

   The purpose of this study is to evaluate the safety and tolerability of AK002 in patients with mast cell gastritis and/or gastroenteritis, examine changes in number of mast cells/HPF in gastric and duodenal biopsies, examine any change in gastrointestinal symptom score as estimated by a daily patient-reported outcome (PRO) questionnaire and look for any changes in absolute peripheral blood eosinophil counts.

7. Filgotinib in Long-Term Extension Study of Adults With Ulcerative Colitis

   Scottsdale/Phoenix, Ariz.

   The primary objective of this study is to observe the long-term safety of filgotinib in adults who have completed or met protocol specified efficacy discontinuation criteria in a prior Gilead-sponsored filgotinib treatment study in ulcerative colitis (UC).

8. Phase 4 Study to Evaluate the Efficacy and Safety of Vedolizumab in the Treatment of Chronic Pouchitis

   Rochester, Minn.

   The purpose of this study is to assess the efficacy and safety of vedolizumab intravenous (IV) in participants with a proctocolectomy and ileal pouch anal anastomosis for ulcerative colitis (UC) who have developed chronic or recurrent pouchitis, or require continuous antibiotic treatment.

9. A Study of the Efficacy and Safety of Risankizumab in Subjects With Crohn's Disease Who Responded to Induction Treatment in M16-006 or M15-991

   Rochester, Minn.

   The study consists of 3 sub-studies, as follows: - Sub-study 1 (Randomized, double-blind, placebo controlled study) to evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in subjects with moderately to severely active Crohn's disease (CD) who responded to risankizumab induction treatment in Study M16-006 or Study M15-991 - Sub-study 2 (Randomized, exploratory maintenance study) to evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in subjects who responded to induction treatment in Study M16-006 or Study M15-991; - Sub-study 3 (Open-label, long-term extension study) to evaluate long-term safety of risankizumab in subjects who completed Sub-study 1 or 2.

10. A Study of Changes to the Microbe Environment in the Intestines of Obese People who Modify Their Diet and Lifestyle

    Rochester, Minn.

    The purpose of this study is to assess changes that occur in the intestine microbe environment of obese people as they perticipate in a structured diet and lifestyle modification.
