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

1. Testing a Combination of Vaccines for Cancer Prevention in Lynch Syndrome

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate if the combination of trivalent adenovirus-5 (Tri-Ad5) vaccines and IL-15 superagonist N-803 reduces the incidence of colorectal neoplasms in patients with Lynch syndrome (LS).

2. 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.

3. 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.

4. 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).

5. Mayo Clinic Inflammatory Bowel Disease Repository

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this research study is to collect clinical information and human samples from patients with IBD. The data collected will be used to create an organized, accessible resource of human samples for biological research in IBD.

6. 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.

7. A Study of Intratumoral Injection of Dendritic Cells after High-Dose Conformal External Beam Radiotherapy in Patients with Unresectable Liver Cancer

   Rochester, Minn.

   Group 1: The primary purpose of this study is to evaluate the safety and tolerability of an autologous dendritic cells (DC) vaccine delivered by intra-tumoral injection in patients with primary liver cancer treated with high-dose conformal external beam radiotherapy (EBRT).

   Group 2: The primary purpose of this study is to estimate the progression-free survival rate at 2 years post-registration to see if treatment is efficacious compared to historical data

8. A Study to Evaluate the Therapeutic Effectiveness of Rifaximin in Diabetic Gastroparesis Patients Using Bloating as the Primary Endpoint

   Jacksonville, Fla.

   The primary purpose of this study is to prospectively assess symptoms of bloating (severity, prevalence) in patients with diabetic gastroparesis.

9. A Study to Develop a Biorepository of Blood Samples from Cancer Patients Participating in the Gemini (IRB 19-006717) Protocol

   Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to develop a biorepository of blood samples  from cancer patients participating in the Gemini (IRB 19-006717) protocol. These samples will be used for future biomarker discovery and other translational studies. 

10. In-home Versus In-Clinic Subcutaneous Nivolumab Administration through Connected and Remote Cancer CARE Beyond Walls

    Jacksonville, Fla.

    The purpose of this study is to evaluate the impact of the location of SQ Nivo administration, at the infusion center or in the home, on patient preference and acceptability, safety, patient reported outcomes (PROs), and clinical outcomes.
