Clinical Trials

The purpose of this study is to demonstrate the performance of the Guardian™ Sensor (3) with an advanced algorithm in subjects age 2 - 80 years, for the span of 170 hours (7 days).

The purpose of this study is to evaluate the effects of improving glycemic control, and/or reducing glycemic variability on gastric emptying, intestinal barrier function, autonomic nerve functions, and epigenetic changes in subjects with type 1 diabetes mellitus (T1DM) and  type 2 diabetes mellitus (T2DM) who are switched to intensive insulin therapy as part of clinical practice.

The objectives of this study are to determine if the 1-year graft success rate following DMEK performed with corneas from donors without diabetes is superior to the graft success rate with cornea donors with diabetes, to determine if the 1-year central endothelial cell loss (ECL) following DMEK performed with corneas from donors without diabetes is superior to the central ECL when corneas from donors with diabetes are used, nd to explore the relationship of severity of diabetes in the donor, as measured by eye bank-determined diabetes risk categorization scores, post-mortem hemoglobin A1c (HbA1c), and skin advanced glycation endproducts (AGE) and oxidation markers, with 1-year graft outcomes (i.e., graft success and ECL) following DMEK in corneas from donors with diabetes.

The association of diabetes in the cornea donor with transplant success and loss of endothelial cells one year following Descemet membrane endothelial keratoplasty (DMEK) will be evaluated in a double-masked multi-center trial in which study eyes will be assigned to receive either a cornea from a donor without diabetes or a cornea from a donor with diabetes.

The objectives of this study are to evaluate the effectiveness and safety of PB in the treatment of patients with hereditary nephrogenic diabetes insipidus, to evaluate the effectiveness and safety of PB in polyuric patients with autosomal dominant polycystic kidney disease treated with tolvaptan, and to evaluate the effectiveness and safety of PB in polyuric patients previously treated with lithium.

As the global epidemic of obesity and diabetes mellitus spreads, an exponential rise in incident chronic kidney disease (CKD) complicated by end stage renal disease (ESRD) is predicted, leaving healthcare systems overwhelmed worldwide. Hence, there is urgent need for novel therapies to slow the progression of DKD and optimize the health of this patient population. The purpose of this study is to examine the effect of a supplement on mesenchymal stem cells, physical body function (or frailty), kidney function, and total clearance of senescent cells in individuals with CKD. At present, we are enrolling participants with CKD, with a subset of participants with diabetic kidney disease (DKD), aged 40-80 years, and eGFR 15-60 mL/min/1.73m2. After screening and enrollment, study participants will be randomized to either the treatment or non-treatment (placebo) arm.  Participants in the treatment arm will take the supplement drug for 2 days.  For all participants, an olive-sized sample of subcutaneous fat will be taken from the abdomen for MSC isolation and repeated at day 14. A frailty assessment along with blood and urine laboratory testing will be done at a total of 3 study visits (enrollment, day 14, and month 4).  Mail-out labs will be accepted for month 12 follow-up. 

The study is being done to find out if low blood sugar (hypoglycemia) can be reduced in people with type 1 diabetes (T1D) 65 years and older with use of automated insulin delivery (AID) system.

The device systems used in this study are approved by the Food and Drug Administration (FDA) for diabetes management. We will be collecting data about how they are used, how well they work, and how safe they are.

This study aims to identify an early stage biomarker for type 1 diabetes. In vitro evidence identified a significant enrichment of the chemokine CXCL10 in β-cell derived EXO upon exposure to diabetogenic pro-inflammatory cytokines. The study also aims to test protocols for efficient isolation of plasma-derived EXO from small volumes of sample, develop an assay for the sensitive detection of CXCL10 in plasma-derived EXO, and characterization of plasma-derived EXO through assessment of concentration, size, and content (proteomics).

The purpose of this study is to evaluate whether or not semaglutide can slow down the growth and worsening of chronic kidney disease in people with type 2 diabetes. Participants will receive semaglutide (active medicine) or placebo ('dummy medicine'). This is known as participants' study medicine - which treatment participants get is decided by chance. Semaglutide is a medicine, doctors can prescribe in some countries for the treatment of type 2 diabetes. Participants will get the study medicine in a pen. Participants will use the pen to inject the medicine in a skin fold once a week. The study will close when there is enough information collected to show clear result of the study. The total time participants will be in this study is about 3 to 5 years, but it could be longer.

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

The purpose of this study is to evaluate 6 weeks of home use of the Control-IQ automated insulin delivery system in individuals with type 2 diabetes.
