Simultaneous Measurement and Responsive Treatment - Part 2

This research study is testing an investigational dual-port insulin patch pump that integrates a continuous glucose monitor (CGM) in adults with type 1 diabetes. The goal of the study is to better understand how insulin delivery near a CGM sensor affects glucose readings and to collect data to support development of a combined insulin pump and CGM system. People with type 1 diabetes require lifelong insulin therapy. Many use insulin pumps and CGMs, but these systems usually involve wearing multiple devices at different body sites. Managing several devices can increase treatment burden and may contribute to skin irritation, device failures, and challenges with glucose control. This study is conducted in two in-patient parts. In Part A, participants will wear three investigational devices at the same time while glucose levels are closely monitored using laboratory blood tests and a commercial CGM. This part of the study is designed to measure how basal and bolus insulin delivery near the CGM sensor affects sensor accuracy and how quickly the sensor signal recovers after insulin delivery. In Part B, participants will wear one investigational device while trained study staff use CGM information from the integrated sensor to guide insulin delivery recommendations generated by an automated glucose control algorithm. Insulin delivery decisions will be closely supervised, and glucose levels will be frequently monitored. Participants will stay at the clinical research center for short, controlled study visits. Safety will be monitored throughout the study, with predefined procedures for treating low or high blood sugar. The information collected will be used to support further development of an integrated insulin pump and CGM system for people with type 1 diabetes.

A Clinical Trial Using Tirzepatide to Help Adults With Type 1 Diabetes Automatically Control Their Blood Sugar

This research study is testing whether a weekly medication called tirzepatide can help adults with type 1 diabetes use their insulin pump more easily, specifically by reducing or eliminating the need to count carbohydrates at meals. People with type 1 diabetes must take insulin for life, and even with advanced insulin pumps and continuous glucose monitors, many still struggle to keep blood sugar within the target range. One of the biggest challenges is carbohydrate counting, which requires estimating the amount of carbohydrates in every meal to give the correct insulin dose. Tirzepatide is a medication currently approved for type 2 diabetes and weight management. Early research suggests it may also help people with type 1 diabetes by lowering appetite, slowing digestion, reducing insulin needs, and smoothing after-meal blood sugar rises. This study will include 105 adults with type 1 diabetes at centers in Canada and Switzerland. Everyone will use the Tandem Control-IQ insulin pump with a Dexcom G7 continuous glucose monitor. Participants are randomly assigned to one of two groups: Tirzepatide group: Participants receive weekly tirzepatide injections. After the dose is gradually increased over 12 weeks, they will eventually try using their insulin pump without entering carbohydrate amounts at meals. Control group: Participants continue their usual therapy and keep counting carbohydrates for their mealtime insulin doses. The main goal of the study is to learn whether people taking tirzepatide can safely maintain good blood sugar control without counting carbs, compared with standard care. All participants will attend several clinic visits and share their glucose, insulin, and health data throughout the 32-week trial. Some centers will also conduct heart/fitness, or body-composition tests. As with any medication, tirzepatide may cause side effects such as nausea, vomiting, diarrhea, or decreased appetite. Rare but serious risks like gallbladder disease or pancreatitis are also monitored. Pregnancy must be avoided during the trial. Overall, this study aims to understand whether adding tirzepatide to automated insulin delivery can simplify diabetes management, reduce burden, and maintain safe and effective glucose control for adults living with type 1 diabetes.

Continuous Ketone Monitoring in People With Type 1 Diabetes Using SGLT2 Inhibitors

Type 1 diabetes is an autoimmune disease where the body attacks the insulin-producing cells in the pancreas. In the absence of insulin, the body is unable to effectively use glucose for energy, resulting in high blood sugar levels. This leads to a lifelong need for intensive insulin therapy to manage blood sugar and prevent complications arising from elevated blood glucose levels. When insulin is low, the body produces ketone bodies. If ketone levels rise too high, they can lead to the dangerous condition known as diabetic ketoacidosis. Diabetic ketoacidosis remains a leading cause of mortality in children and young adults with type 1 diabetes. Sodium/glucose cotransporter 2 inhibitors, such as empagliflozin, are effective in lowering blood sugar but can also increase ketone levels, raising the risk of diabetic ketoacidosis. Empagliflozin is approved for type 2 diabetes and has demonstrated benefits in type 1 diabetes, including improved blood sugar control at lower doses and reduced risks of chronic kidney disease and mortality at higher doses. However, its use in type 1 diabetes is still off-label due to the heightened risk of diabetic ketoacidosis. Using empagliflozin at a commercial dose safely is desirable to maximize its potential renal benefits in type 1 diabetes. While there are measures to monitor ketone levels, current methods, such as finger prick tests, often detect issues too late to prevent diabetic ketoacidosis. Continuous ketone monitoring offers real-time tracking of ketone levels, which could enable timely interventions to maintain safe levels. Moreover, there is currently no data on continuous ketone metrics in individuals with type 1 diabetes using sodium/glucose cotransporter 2 inhibitors. We aim to understand the dynamics of ketone levels in people with type 1 diabetes using empagliflozin, including in challenging situations such as during exercise and low-carbohydrate diets while on sodium/glucose cotransporter 2 inhibitors. To this end, we will conduct an open- label, single-arm, outpatient study where 24 participants with type 1 diabetes will use continuous ketone monitoring for a 4-week run-in, followed by empagliflozin 2.5 mg for four weeks and then empagliflozin 10 mg for nine weeks. Participants will perform an exercise sub-study during the fourth week of the continuous ketone monitoring run-in and during the eighth week of empagliflozin 10 mg use. Certain participants will be invited to undergo a low-carbohydrate diet during the last week of empagliflozin 10 mg use. The results, if positive, may lead to i) novel long-term (6 months) data on ketone levels in those with type 1 diabetes using empagliflozin, including individuals on multiple daily injections and closed-loop therapy across a wide range of body mass index, ii) data on the relationship between empagliflozin, exercise, low-carbohydrate diets, and type 1 diabetes, and iii) the creation of important metrics for ketone thresholds that have not yet been characterized. Furthermore, we hope this preliminary study will inform future research to investigate the use of continuous ketone monitoring to allow for the safe use of higher doses of sodium/glucose cotransporter 2 inhibitors in people with type 1 diabetes.
