1. A Study To Examine Quality of Life Assessment in Patients Receiving Cryotherapy for Palliation of Dysphagia in Unresectable Esophageal or Gastroesophageal Junctional Cancer

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to determine the effect of endoscopic cryoablation for lessening the effects of dysphagia on the quality of life (QOL) of patients with unresectable esophageal or gastroesophageal junctional cancer.

2. Obesity Treatment Outcomes in Liver Transplant Recipients

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to prospectively evaluate the safety and effectiveness of standard of care, individualized, comprehensive weight loss interventions in carefully selected patients with obesity undergoing liver transplant evaluation, including utilization of best lifestyle modifications and guidance to promote a healthy weight, possible medical therapy using FDA-approved weight loss medications and EBMTs with or without concomitant medical therapy.

3. A Study to Evaluate Evacuation Mechanisms Using Advanced Brain Imaging

   Rochester, Minn.

   The objective of this study is to compare the central neural circuitry with fMRI (7T) in 30 asymptomatic healthy controls, 30 constipated patients without DD, and 30 constipated patients with DD at rest (functional connectivity analysis), during rectal distention to desire to defecate and urgency, and during evacuation. 

    

    

    

4. A Study to Evaluate the Safety, Tolerability, and Determine the Optimal Dose for the Expansion Cohorts of VSV-IFNβ-NIS in Combination with Pembrolizumab in Patients with Refractory Solid Tumors

   Rochester, Minn.

   The purpose of this study is to determine the safety of VSV-IFNβ-NIS in combination with pembrolizumab, followed by expansion to examine effectiveness of combination therapy in patients with refractory Non-Small Cell Lung Cancer (NSCLC) or Hepatocellular Carcinoma (HCC).

5. A Safety to Evaluate the Safety and Effectiveness of Pressurized Intraperitoneal Aerosolized Chemotherapy in Ovarian, Uterine, Colorectal, and Gastric Cancer Patients

   Jacksonville, Fla.

   The purpose of this study is to evaluate the safety of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in 2 groups of patients with peritoneal carcinomatosis (PC), either due to primary ovarian, uterine, or gastric carcinoma (Arm 1) or to primary colorectal carcinoma (Arm 2), based on treatment-related adverse events reported by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.  

6. A Study to Develop a Registry for Outcomes and Predictors in Pouch-Related Disorders

   Rochester, Minn.

   The primary purpose of this study is to create a prospective registry of patients with pouch-related conditions to allow for longitudinal assessment of outcomes at 3, 6 and 12 months after a enrollment with a specific diagnosis (acute pouchitis, CADP, CARP, or CD of the pouch).

7. Effect of Cholecystokinin (CCK) on Gastroduodenal Activity in Humans

   Rochester, Minn.

   The purpose of this research study to compare the effects a hormone cholecystokinin (CCK) in the bloodstream in healthy people and in patients with rapid gastric emptying. CCK regulates (controls) the rate at which food empties from the stomach into the small intestine. We want to learn how CCK affects the activity of the stomach and small intestines in patients with rapid gastric emptying. We are also trying to learn if genes regulate the effects of CCK.

8. A Study to Evaluate the Effectiveness of Diaphragmatic Breathing on Reflux Symptoms in Outpatients

   Jacksonville, Fla.

   The purpose of this study is to establish if abdominal breathing exercises can reduce symptoms associated with reflux.

9. A Study to Evaluate the Effects of Tradipitant on Satiation, Gastric Volume, Gastric Accommodation, and Gastric Emptying in Healthy Volunteers

   Rochester, Minn.

   The purpose of this study is to evaluate the effects of tradipitant relative to placebo in healthy volunteers:

   • Difference in fasting GV;
   • Difference in postprandial GV and in accommodation volume (that is, postprandial minus fasting gastric volumes);
   • Difference in gastric emptying (T1/2, emptying at 2h and emptying at 4h);
   • Volume to fullness (sensation of usual postprandial fullness) and maximum feeling of fullness (MTV).

10. A Study to Assess Intestinal Barrier Function and Permeability in Patients with Functional Dyspepsia

    Jacksonville, Fla.

    The purpose of this study is to investigate, using several novel techniques, potential pathophysiologic abnormalities that could lead to the development of symptoms of functional dyspepsia.
