1. Concomitant Renal and Urinary Bladder Allograft Transplantation

   Rochester, Minn.

   Patients that need reconstruction or re-building of their urinary bladder are often limited to having a segment of their intestine used for that purpose. Using intestine is less than ideal as it is an absorptive, mucous producing tissue and placing this in constant contact with urine creates significant long term problems. In patients that require a kidney transplant and bladder reconstruction, this study seeks to use a bladder graft from a deceased donor rather than intestine.

2. Cellular Immunotherapy for Viral Induced Cancer - EBV Positive Lymphomas

   Rochester, Minn.

   To investigate the efficacy of autologous Epstein-barr virus (EBV)-specific T cells for the treatment of EBV positive Diffuse Large B Cell Lymphoma (DLBCL), Hodgkin Lymphoma (HL) and Post-transplant Lymphoproliferative Disease (PTLD) after failing first line treatment.

3. A Study of Study of Immune Tolerance Mechanisms in Kidney Transplant Patients

   Scottsdale/Phoenix, Ariz.

   Hypothesis: we hypothesize that the abundance and functions of Breg subsets in kidney transplant patients could be associated with transplant tolerance and rejection, including DSA-mediated kidney transplant rejection. In addition, oral corticosteroid treatment significantly alters the frequency and function of Breg subsets, which could lead altered clinical outcomes.
   
   Aims, purpose, or objectives:
   1. Investigate the frequency Bregs and their ability to express IL-10 along with other immune cells in the context of tolerance/rejection in kidney transplant patients.
   we hypothesize that the abundance and functions of Breg subsets in kidney transplant patients could be associated with transplant tolerance and rejection, including DSA-mediated kidney transplant rejection.
   
   2.Investigate the frequency and functions of Bregs along with other immune cells in the setting of long term corticosteroid use.
   We hypothesize that oral corticosteroid treatment significantly alters the frequency and function of Breg subsets, which could lead altered clinical outcomes.

4. A Study to Develop a Breath Analysis Test

   Jacksonville, Fla.

   The purposes of this study are to establish breath sample collection and analysis techniques, to establish reference ranges for selected clinical populations, and to assess correlations between breath analysis and presence or absence of clinical or pathological evidence of disease.

5. Autologous Induced Pluripotent Stem Cells of Cardiac Lineage Delivered Into Heart Muscle for Congenital Heart Disease

   Rochester, Minn.

   The purpose of this study to test the feasibility and safety for autologous (from your own body) skin cells that are manufactured into stem cells of cardiac lineage to be delivered into the heart muscle to determine if those stem cells will strengthen the heart muscle and can be used as an additional treatment for the management of  congenital heart disease. 

6. Mismatched Related Donor Versus Matched Unrelated Donor Stem Cell Transplantation for Children, Adolescents, and Young Adults With Acute Leukemia or Myelodysplastic Syndrome

   Rochester, Minn.

   The purpose of this study is to compare the 1-year cumulative incidence of severe GVHD (from day of HCT) defined as Grade III-IV acute GVHD (aGVHD) and/or chronic GVHD (cGVHD) that requires systemic immunosuppression and to compare the disease free survival (DFS) (from time of randomization) in children and young adults (AYA) with acute myeloid leukemia (AML), acute lymphoid leukemia (ALL), and Myelodysplastic Syndrome (MDS) who are randomly assigned to haploHCT or to an 8/8 adult MUD HCT.

7. A Study to Evaluate Alloantibody Titer in Highly Sensitized Kidney Transplant Candidates

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

   The purpose of this study is to evaluate the utility of using anti-HLA antibody titer to measure the effectiveness of antibody lowering therapy (i.e., desensitization) in highly-sensitized kidney transplant candidates.

    

8. A Study to Assess Reproductive History in Kidney Donors

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to analyze the effect of parity, menopause and reproductive lifespan on kidney structure and function.

9. A Study to Evaluate Wellness Coaching for Caregivers of Thoracic Transplant Candidates

   Rochester, Minn.

   The purpose of this study is to examine the effects of a health coaching intervention on the stress and burden of caregivers of patients awaiting heart or lung transplant.

   Hypotheses:  Caregivers will have traits and behaviors pre-transplant that will predict caregiver readiness, quality of life, and transplant recipient outcomes. Specifically, thoracic pre-transplant caregivers report stress, symptoms of anxiety or depression, and perceive high caregiver burden. These factors may be amenable to pre-transplant intervention to improve overall patient and caregiver outcomes.

   Aims, purpose, or objectives:  We will conduct a pilot trial to test whether caregivers of heart and lung transplant candidates who receive wellness coaching will experience improvement in caregiver-related distress. We will also explore the relationship between caregiving and factors such as uncertainty, resilience, stress level, and affect.

10. A Study to Evaluate Immune and Hematopoietic Cell Assessment in Clonal B Cell Conditions

    Rochester, Minn.

    The purpose of this study is to evaluate the immune and hematopoietic compartments in patients with monoclonal B cell lymphocytosis (MBL) and chronic lymphocytic leukemia (CLL) in comparison to age-matched healthy control (HC) donors.
