1. Study of Pembrolizumab (MK-3475) vs Standard Therapy in Participants With Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Stage IV Colorectal Carcinoma (MK-3475-177/KEYNOTE-177)

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   In this study, participants with MSI-H or dMMR advanced colorectal carcinoma will be randomly assigned to receive either pembrolizumab or the Investigator's choice of 1 of 6 standard of care (SOC) chemotherapy regimens for the treatment of advanced colorectal carcinoma. The primary study hypothesis is that pembrolizumab will prolong progression-free survival (PFS) or overall survival (OS) compared to current SOC chemotherapy.

2. 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.

3. Minimally Invasive Molecular Approaches for the Diagnosis of Barrett's Esophagus and Esophageal Adenocarcinoma

   Rochester, Minn., Mankato, Minn., Jacksonville, Fla., Austin, Minn., Eau Claire, Wis., Scottsdale/Phoenix, Ariz.

   This study will evaluate if the sponge capsule device can accurately detect the presence of Barrett's Esophagus and prevalent dysplasia/adenocarcinoma detection, in a screening population, with and without chronic gastroesophageal reflux disease.

4. Comparison Of In-Home Versus In-Clinic Administration Of Subcutaneous Nivolumab Through Cancer CARE (Connected Access And Remote Expertise) Beyond Walls (CCBW) Program

   Jacksonville, Fla.

   This phase II trial compares the impact of subcutaneous (SC) nivolumab given in an in-home setting to an in-clinic setting on cancer care and quality of life. Currently, most drug-related cancer care is conducted in clinic type centers or hospitals which may isolate patients from family, friends and familiar surroundings for many hours per day. This separation adds to the physical, emotional, social, and financial burden for patients and their families. Traveling to and from medical facilities costs time, money, and effort and can be a disadvantage to patients living in rural areas, those with low incomes or poor access to transport. Studies have shown that cancer patients often feel more comfortable and secure being cared for in their own home environments. SC nivolumab in-home treatment may be safe, tolerable and/or effective when compared to in-clinic treatment and may reduce the burden of cancer and improve the quality of life in cancer patients.

5. Influence of Diet on Tissue and Body Fluids in Health and Disease

   Scottsdale/Phoenix, Ariz.

   This study aims to compare the fatty acid composition of small sample of fat (visceral and subcutaneous) removed at the time of surgery to operative outcomes and the composition calculated from the person’s dietary history and preoperative imaging with MRI/CT scans. This study will also compare the composition of pancreatic fluid collected to that of a sample of fat removed at the time of surgery to drain the collection. Furthermore, we will study the fatty acid composition of drain fluid placed at the time of surgery to that of their fat samples.

6. A Study to Evaluate Encorafenib Plus Cetuximab with/without Chemotherapy to Treat Metastatic Colorectal Cancer

   Scottsdale/Phoenix, Ariz., Rochester, Minn.

   The purpose of this study is to evaluate whether encorafenib plus cetuximab (EC), alone or in combination with chemotherapy, can improve clinical outcomes relative to current standard of care chemotherapy in participants with previously untreated BRAF V600E-mutant metastatic colorectal cancer (mCRC).

7. The Olmsted NAFLD Epidemiology Study (TONES)

   Rochester, Minn.

   About this study

   Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the world and a major public health issue in the US. It is estimated to affect 1 in 4 adults and it is most commonly found in people who are overweight or obese. Because it is a silent disease (without symptoms until end stage) and the lab tests can be normal, it can be missed in early stages. The fat in the liver can lead to inflammation and eventually scar deposition, which can progress to cirrhosis, liver cancer and need for liver transplantation.

   This study aims to assess how common this disease is in Olmsted County, what markers can identify the disease early to prevent progression to cirrhosis and what other medical problems occur in people with NAFLD in addition to the liver complications. We plan to enroll a large number of adults, assess their liver with state-of-the-art tests available at Mayo Clinic and follow them over several years to monitor for disease progression and other health complications. The ultimate goal of the study is to identify new markers that predict presence of fatty liver and poor health outcomes, in order to improve population health in the community.

   Participation eligibility

   Participants will be identified from the Olmsted County population age 18 or older.

   Inclusion criteria:

   1.         Adults age 18 years or older

   2.         Olmsted County residents at the time of study entry

    

   Exclusion criteria:

   1.         Pediatric population (age<18)

   2.         Unwilling to participate or unable to consent

   3.         Known liver disease other than NAFLD at the time of survey

   4.         Pregnant women

   5.         Alcohol use in excess (14 drinks or more per week for women and 21 drinks or more per week for men)

8. 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.

9. 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. 

10. 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.
