1. A Study to Evaluate Intra-arterial Delivery of Mesenchymal Stem Cells for Luminal Ulcerative Colitis

   Rochester, Minn.

   Ulcerative Colitis (UC) is a chronic inflammatory disease affecting the mucosal lining of the colon and rectum and the incidence is increasing, but the etiology remains unknown. Patients may require a proctocolectomy due to refractory disease. Prior to an operation, UC is treated with antibiotic therapy, immunomodulatory therapy and immunosuppressive agents. While there is an increasing number of approved biologics for the treatment of UC, there are many patients that still suffer from refractory disease. Thus, alternative mechanisms of therapy are desperately needed.

   Treatments that have the potential to reduce mucosal inflammation could alleviate the pathology of luminal UC. This trial will use arterially delivered mesenchymal stem cells (MSCs) to produce these regenerative signals allowing for mucosal healing. This study will enroll patients with medically refractory moderate to severe inflammatory UC who are or plan to be scheduled for a colectomy. Patients enrolled will be those who failed all attempts at standard treatment including antibiotics, corticosteroids, immunomodulator, and/or biologic therapy.

   Participants will undergo screening for study, if eligible, participants will be dosed with 15 million or 30 million cells will be administered via IA delivery with interventional radiology. Participant study visits after study intervention includes visits on: Day 1, Week 1, Week 2, Week 8, Week 24, Week 52, and Week 104.

2. A Study to Evaluate Ramucirumab Plus Trifluridine/Tipiracil to Treat Patients with Previously-treated Advanced Gastric or Gastro-esophageal Junction Adenocarcinoma

   Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to compare, in a non-inferiority fashion, the progression-free survival (PFS) in patients with metastatic refractory gastric/Gastroesophageal Junction (GEJ) adenocarcinoma receiving the combination of ramucirumab with TAS-102 vs. paclitaxel and ramucirumab.

    

3. Novel Stomal Occlusion Device in Patients With a Brooke Ileostomy

   Rochester, Minn.

   This investigation constitutes an initial evaluation of the stoma occlusion device in humans with a mature permanent Brooke ileostomy. The overall objective of this study is to assess feasibility and initial operating characteristics of a novel stoma occlusion device. The study will recruit 20 patients for placement of the device into the mature Brooke ileostomy and subsequent 2 hour observation period. The device will remain in the ileostomy for up to 2 hours.

4. A Study to Evaluate the Effect of POSE2 on Long-term Gastric Motor Function

   Rochester, Minn.

   The purpose of this study is to explore the effectiveness and safety of a modified gastroplication technique for weight loss in five patients with obesity, and includes physiologic appraisal of gastric emptying (via gastric emptying breath test) and post-prandial gastric accommodation (via SPECT).

5. Mucosal and Microbiota Changes During Acute Campylobacteriosis

   Rochester, Minn.

   Gastrointestinal (GI) infection with Campylobacter causes inflammation in the bowel and can change bacteria in the gut. Certain individuals with Campylobacter infection are also known to develop chronic bowel problems such as Irritable Bowel Syndrome (IBS). The researchers are doing this study to understand if changes in gut bacteria and gut mucosal lining during an acute infection can help identify individuals who might be at risk for developing problems in the future.

6. A Bio-bank for Patients with Inflammatory Bowel Disease Associated Neoplasia

   Rochester, Minn.

   The purpose of this study is to collect blood and stool samples to validate and improve the performance of stool and blood DNA markers for inflammatory bowel disease and colorectal neoplasia critical to the long-term goal of improving effectiveness of neoplasia detection in patients using non-invasive biomarkers to assist colonoscopy and radiographic screening. 

7. Cohort of Patients With Fatty Liver Disease

   Jacksonville, Fla.

   The purpose of this research is to create a registry of patients having or at risk for metabolic liver disease for investigations into the molecular pathogenesis of cirrhosis, liver cancer, and end-stage liver disease.
