1. Gastrointestinal-Related Cancers and Diseases

   Rochester, Minn.

   The purpose of applying to the Institutional Review Board (IRB) for the collection of GI-related tissue is to enable comprehensive molecular investigations into the mechanisms underlying gastrointestinal cancers and diseases.

2. A Colon Bank for Early Detection of Colon Cancer

   Rochester, Minn.

   The purpose of this study is to establish a biobank of samples (blood and stool) to support the development of non-invasive tests for early detection of colon cancer and its precursors.

3. A Study to Evaluate Colorectal Polyps with Dietary Inflammation During Colonoscopy

   Jacksonville, Fla.

   Colorectal cancer is the third most commonly diagnosed cancer in both men and women in the United States (1). Colorectal cancer arises from colonic polyps. The major types of polyps associated with colorectal cancer development are adenomatous (tubular which is most common and other types are villous and tubulovillous) and serrated (hyperplastic, sessile or traditional) polyps with varying degrees of dysplasia (2). Hyperplastic polyps are common but they have a low malignancy potential (3). There is evidence that colonic inflammation plays a major role in colon polyp and colorectal cancer development. For example, inflammatory bowel disease is a major predisposing factor for colorectal cancer occurrence, implicating inflammation in the development of colorectal cancer (4). In addition,  obesity, a chronic inflammatory state, is associated with increased colorectal cancer risk (5). However, the use of anti-inflammatory agents in the prevention of colorectal cancer is controversial, although there is some suggestion that its use may lower colorectal cancer risk (6,7). Diet may affect cytokine levels and inflammation (8). Diet rich in trans-fat and sugar has been shown to increase pro-inflammatory cytokines IL-6 and TNFα (9, 10) and the Mediterranean Diet has been shown to decrease inflammatory cytokines (11) and decrease the risk of colon cancer in an UK study (12). Recently, the EDII was developed and validated to assess inflammatory potential of diet based on the Food Frequency Questionnaire (FFQ) (13).  Here we propose to investigate the association between diet-derived inflammation, as measured by the EDII, risk of colon polyps during screening colonoscopy and colorectal cancer development.

4. Stem Cell Coated Fistula Plug in Patients With Crohn's RVF

   Rochester, Minn.

   The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with rectovaginal fistulizing Crohn's disease. Autologous means that these cells that coat the plug come from you. You will be in this study for two years. There is potential to continue to monitor your progress with lifelong regular visits as part of your standard of care. All study visits take place at Mayo Clinic and Rochester, MN. The study visit schedule is as follows: Visit 1 (Week -6) - Screening visit: exam under anesthesia and surgery to assess eligibility of fistula tract, take fat biopsy, if eligible, and fecal diversion. Visit 2 (Week 0; Day 0), exam under anesthesia for stem cell coated fistula plug placement Visit 3 (Week 0; Day 1) Visit 4 (Week 2; Month 1) Visit 5 (Week 4; Month 1) Visit 6 (Week 8; Month 2) Visit 7 (Week 12; Month 3) Visit 8 (Week 24; Month 6) Visit 9 (Week 52; Month 12). Visit 10 (Week 104, Month 24)

5. A Study to Understand the Mechanisms of Normal and Disordered Defection

   Rochester, Minn.

   The purpose of this study is to compare rectal emptying and rectoanal pressures in healthy people and DD. Our hypotheses are that (i) the rate and amount of rectal emptying is higher in healthy people than in patients with DD, (ii) some patients with symptoms of DD will have a normal balloon expulsion test but reduced rectal emptying measured with fecomanoflowmetry, and (iii) compared to healthy people, the rectal pressure increment and/or anal relaxation is reduced in patients with DD.
    

6. Data Collection of PillCamTM SB3 Capsule Endoscopy and Device-Assisted Enteroscopy Routine Care Procedures (GPS Study)

   Jacksonville, Fla.

   The purpose of this study is to collect PillCamTM SB3 capsule endoscopy (CE) procedures and subsequent device-assisted enteroscopy (DAE) procedures data (double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) and spiral enteroscopy (SE)) in medical centers in the United States (US).

7. A Study to Assess the Efficacy and Safety of Risankizumab in Subjects With Moderately to Severely Active Crohn's Disease Who Failed Prior Biologic Treatment

   Rochester, Minn.

   The objective of Study M15-991 is to evaluate the efficacy and safety of risankizumab versus placebo during induction therapy in subjects with moderately to severely active CD.

8. Study of Gastric Cancer and Limited Peritoneal Metastasis Using Robotic Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy

   Rochester, Minn.

   The purpose of this study is to assess short-term morbidity and disease-free survival outcomes for patients with gastric adenocarcinoma with limited low volume peritoneal metastasis and/or positive peritoneal cytology undergoing robotic cytoreduction and hyperthermic intraperitoneal chemotherapy.

9. Study to Evaluate Efficacy, Safety and Tolerability of HM15211 in Subjects

   Rochester, Minn.

   The purpose of this study is to assess the pharmacodynamics (PD) of HM15211 after administration of multiple subcutaneous (SC) doses compared to placebo on the liver by proportion of subjects who achieve resolution of steatohepatitis on overall histopathological reading and no worsening of liver fibrosis on NASH Clinical Research Network (CRN) fibrosis score.

   Resolution of NASH is defined as non-alcoholic fatty liver disease (NAFLD) activity score (NAS) of 0–1 for inflammation, 0 for ballooning, and any other value for steatosis

10. A Study to Evaluate the Effectiveness of a Healthy Living Weight Loss Program in Obese Patients Undergoing Bariatric Endoscopy on Weight Loss Outcomes

    Rochester, Minn.

    The purpose of this study is to compare weight loss, improvement of comorbidities, improvement of lipid profile, blood sugar in patients undergoing endoscopic sleeve gastroplasty or intragastric balloon between patients who are in a weight loss program and those who are not.
