Study to Evaluate Safety and Efficacy of IBsolvMIR in Islet Transplantation
Diabetes MellitusType 1This is a Phase II open, randomized, active comparator-controlled multi center study in patients with severe type-1 diabetes. This is a two-armed study where patients are randomized in a 2:1 ratio between IBsolvMIR and heparin. Eighteen patients are planned to be included. The study consists of up to 8 visits; screening, transplantation surgery with bolus administration of study drug or active comparator, IBsolvMIR doses on day 1, 3 and 6 after surgery, follow up visits on day 7 and 14, and follow-up phone call on day 44. The primary endpoint is to study AEs up to 44 days following study drug administration. The secondary endpoints are to evaluate changes in TAT, C-peptide, C3a and HGF at baseline and during the first 24 hours after study drug administration, as well as evaluate a change in levels of C-peptide-glucose-creatinine ratio on day 14 compared to baseline.
Hypoglycemia Associated Autonomic Failure in Type 1 Diabetes Mellitus (DM)
Type 1 DiabetesHypoglycemia Associated Autonomic FailureExercise is a cornerstone of diabetes management. It helps reduce blood pressure, promote weight loss, lower insulin resistance and improve glucose and lipid (triglyceride and HDL-cholesterol) profiles. Unfortunately, the benefits of exercise are often not embraced by diabetic individuals because of the fear of low blood sugar (hypoglycemia). My laboratory has demonstrated that Autonomic nervous system (ANS) counterregulatory failure plays an important role in exercise associated hypoglycemia in Type 1 DM. ANS responses are significantly reduced in Type 1 DM and are further blunted by antecedent episodes of hypoglycemia. Furthermore, there is a large sexual dimorphism of reduced ANS responses during submaximal exercise in both Type 1 DM and healthy individuals that is unexplained. Accumulating data are demonstrating that serotonergic pathways can regulate ANS discharge. Generally, serotonergic pathways are inhibitory but both single and longer term administration of selective serotonin reuptake inhibitors (SSRI's) such as Prozac has been demonstrated to increase basal epinephrine levels and enhance baroreflex control of Sympathetic nervous system (SNS) activity. What is unknown is whether fluoxetine can also enhance SNS responses and also override the large ANS sexual dimorphism present during sub maximal exercise. Therefore, the purpose of this study is to determine if the SSRI fluoxetine (Prozac) can improve SNS responses during exercise.
Islet Transplantation Using PKX-001
Type 1 Diabetes MellitusIslet Transplantation is a procedure used in people with difficult to control Type 1 Diabetes. Insulin producing cells (islets) are isolated from a deceased donor pancreas. After the cells are carefully isolated from the donor pancreas, the islets are transplanted into the recipient's liver. These transplanted islets may produce insulin. One of the challenges with islet transplant is the death of some of the transplanted islets due to inflammation, oxidative stress and exposure to diabetogenic immunosuppressive agents associated with islet functional impairment and graft loss, especially linked to the use of calcineurin inhibitors, including tacrolimus (Tac). Antiaging glycopeptide (PKX-001) is a small, stable, synthetic replica of antifreeze proteins (AFPs), which naturally occur in Arctic and Antarctic fish and have been shown protecting cells against harmful conditions. PKX-001 is a new drug that has been shown in lab studies to help islet cells survive isolation and keep them healthy and functioning. Most importantly, animal studies have shown that islets treated with PKX-001 were protected from the immunosuppressant (Tac) toxicity and retained their function in animals receiving islet transplant. This study will involve up to 10 participants from the islet transplant waiting list at the Clinical Islet Transplant Program. All participants will receive islets treated with the medication PKX-001. PKX-001 will be used only in the islet preservation process, and will not be given to participants as medication. The purpose of this study is to confirm the safety of transplantation of PKX-001 treated islets and to evaluate the cytoprotective capacity of PKX-001 in islet transplantation, especially its capacity to protect against Tac induced graft dysfunction.
Pancreatic Islets and Parathyroid Gland Co-transplantation for Treatment of Type 1 Diabetes
Type 1 DiabetesThe primary objective is to test the hypothesis that co-transplantation of allogeneic PTG with adult pancreatic islets (derived from same deceased donor) in the IM site in people with Type 1 diabetes with functioning kidney and/or liver transplants is safe, allows islet engraftment, and leads to insulin independence.
Clinical Application of Stem Cell Educator Therapy in Type 1 Diabetes
Type 1 DiabetesType 1 diabetes (T1D) is a T cell-mediated autoimmune disease that causes a deficit of pancreatic islet beta cells. Millions of individuals worldwide have T1D, and incidence increases annually. Several recent clinical trials point to the need for an approach that produces comprehensive immune modulation at both the local pancreatic and systemic levels. Stem Cell Educator (SCE) therapy offers comprehensive immune modulation at both the local and systemic levels in T1D by using a patient's own immune cells (including platelets) that are "educated" by cord blood stem cells. Tested clinically in more than 200 patients, SCE therapy has shown lasting reversal in autoimmunity in T1D patients, including improved C-peptide levels, reduced median glycated hemoglobin A1C (HbA1C) values, and decreased median daily usage of insulin. SCE therapy circulates a patient's blood through a blood cell separator, briefly cocultures the patient's immune cells with adherent Cord Blood Stem Cells (CB-SCs) in vitro, and returns the "educated" autologous immune cells to the patient's circulation.
RT-CGM in Young Adults at Risk of DKA
Diabetes MellitusDiabetes Mellitus5 morePilot study to evaluate the effect of real time continuous glucose monitoring (RT-CGM) on young-adults with insulin-treated diabetes, who are defined as high risk due to suboptimal HbA1c (blood glucose control) or a history of hospital admissions for high blood glucoses. Hypothesis: RT-CGM provided to young adults with suboptimal blood glucose control, has a beneficial impact on HbA1c and hospital admissions for high blood glucoses. We will use data from this pilot work to inform a larger powered study to address this knowledge gap.
