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.

Diabetes mellitus is a common condition which is defined by persistently high blood sugar levels. This is a frequent problem that is most commonly due to type 2 diabetes. However, it is now recognized that a small portion of the population with diabetes have an underlying problem with their pancreas, such as chronic pancreatitis or pancreatic cancer, as the cause of their diabetes. Currently, there is no test to identify the small number of patients who have diabetes caused by a primary problem with their pancreas.

The goal of this study is to develop a test to distinguish these various causes of diabetes. To accomplish this goal, we will enroll a range of patients. Most of the patients enrolled for these groups will have developed diabetes within the last 3 years, but we will also enroll a small number of patients with long-term diabetes and normal blood sugars for comparison.

The purpose of this study is to collect blood samples for biomarker assessment in type 1 diabetes prior to and at specific time points during closed loop control.

The purpose of this study is to assess the glycemic variability in patients with type 1 diabetes admitted in the hospital using a glycemic sensor.

The purpose of this project is to collect data over the first year of clinical use of the FDA approved 670G closed loop insulin delivery system among patients with type 1 diabetes. The goal is to evaluate how this newly approved system impacts both clinical and patient-reported outcomes.

The purpose of this study is to measure and characterize specific immune cell abnormalities found in patients who have type 1 diabetes and are on the waiting list for either a pancreas alone or a pancreas and kidney transplant.

The purpose of this study is to demonstrate the safety and effectiveness of the Hybrid Closed Loop system (HCL) in adult and pediatric patients with type 1 diabetes in the home setting. A diverse population of patients with type 1 diabetes will be studied. The study population will have a large range for duration of diabetes and glycemic control, as measured by glycosylated hemoglobin (A1C). They will be enrolled in the study regardless of their prior diabetes regimen, including using Multiple Daily Injections (MDI), Continuous Subcutaneous Insulin Infusion (CSII) or Sensor-Augmented Pump therapy (SAP)

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 (i)assess glucose variability at pre specified time points after Pancreas Transplantation (ii) collect pre-specified serious adverse events after PT and in appropriate control groups (iii) assess mixed meal dynamics after pancreas transplantation.

The purpose of this study is to compare the effectiveness and safety of an automated insulin delivery (AID) study system using a Model Predictive Control (MPC) algorithm versus Sensor Augmented Pump (SAP) (which may or may not include PLGS; to be referred to as SAP) therapy in people with type 1 diabetes. A Pilot Phase involving up to 7 participants using the study system for 10-14 days will be conducted prior to the crossover trial.

The purpose of this research is to create a single registry for type 1 diabetes at Mayo Rochester and affiliated Mayo sites.

The objective of the study is to assess efficacy and safety of a closed loop system (t:slim X2 with Control-IQ Technology) in a large randomized controlled trial.

The purpose of this study is to compare the effectiveness and safety of an automated insulin delivery (AID) system using a model predictive control (MPC) algorithm versus Sensor-Augmented Pump/Predictive Low Glucose Suspend (SAP/PLGS) therapy with different stress assessments over a 4-week period.

The purpose of this 3-month extension study (DCLP3 Extension) following a primary trial (DCLP3 or NCT03563313) to assess effectiveness and safety of a closed loop system (t:slim X2 with Control-IQ Technology) in a large randomized controlled trial.

The purpose of this study is for clinical staff to gain experience using the proposed artificial pancreas system named inControl and the inControl Cloud and then assess 24/7 in-home usability prior to initiating a large randomized controlled trial.

The objective of the study is to assess the efficacy and safety of home use of a Control-to-Range (CTR) closed-loop (CL) system.

The study is designed to understand the confidence and competence level of patients with type 1 diabetes mellitus in their ability to make changes to their insulin pump.

This clinical trial will identify exercise-related and emotional stress related effects on glycemic control in patients with type 1 diabetes using sensor-augmented pump (SAP) therapy.

The purpose of this study is to collect device data to assist in the development of a Personalized Closed Loop (PCL) system.

The purpose of this study is to identify immune mediated diabetes in patients treated with PD 1 inhibitors, and characterizing its clinical course, laboratory features and possible risk factors. 

The purpose of this study is to evaluate glucose variability in patients with type 1 diabetes (T1D) and insulin antibodies, to evaluate the clinical significance of insulin antibodies, and to establish an in vitro assay that would detect antibodies to insulin and insulin analogs.

The purpose of this study is to use multiple devices to measure blood sugar changes and the reasons for these changes in healthy and diabetic children.

The purpose of this study is to estimate the risk of diabetes related complications after total pancreatectomy.  We will contact long term survivors after total pancreatectomy to obtain data regarding diabetes related end organ complications.

The purpose of this study is to serve as a comparator group to a group of patients that will be managed with AP for varying periods of time during pregnancy.

Hypothesis: Increased contact with the diabetes care team throughout pregnancy will lead to improved glucose control during pregnancy.

The purpose of this study is to identify risk factors for ICI associated diabetes mellitus and to assess the severity and natural course of this immune related adverse effect.

The purpose of this study is to use the USS Virginia Closed-Loop system for overnight insulin delivery in adults with Type 1 Diabetes (T1DM) in an outpatient setting to evaluate the system's ability to significantly improve blood glucose levels. This protocol will test the feasibility of "bedside" closed-loop control - an approach comprised of standard sensor-augmented pump therapy during the day using off-the-shelf devices and overnight closed-loop control using experimental devices in an outpatient setting. The rationale for this study is as follows: we anticipate that closed-loop control may ultimately be adopted by patients with T1DM in a selective manner. Patient may choose to start using these systems for overnight control only, e.g. to alleviate the well documented fear of hypoglycemia while asleep. To test this paradigm of "bedside" closed-loop control, subjects will be studied with continuous glucose monitoring (CGM)-augmented usual pump therapy during the day followed by overnight use of USS Virginia Closed Loop Control.
