Effect of SGLT2i in Conjunction With the Artificial Pancreas on Improving the Glycemia in T1DM in the Outpatient Setting — CLASS17  

Type1 Diabetes Mellitus Clinical Trial

Official title:
Effect of SGLT2 Inhibition on Improving the Glycemic Performance of the Single Hormone Artificial Pancreas Configuration in Type 1 Diabetes in the Outpatient Setting - A Randomized Placebo Controlled Cross-Over Multicentre Clinical Trial

Clinical Trial Summary

The most advanced configurations of the Artificial Pancreas (AP) have not yet been demonstrated to sufficiently maximize time in target glycemia. One limitation is the challenge of postprandial glycemic control, which currently requires ongoing patient engagement for accurate and detailed bolus dose estimation for meals. Sodium Glucose Linked Transporter 2 Inhibition (SGLT2i) provides an additional mechanism to attenuate post-prandial glycemic excursion, and may represent a strategy that could further alleviate carbohydrate counting burden and improve the performance of AP configurations. This trial aims to compare - using a randomized, masked placebo-controlled, crossover, multicenter design - the efficacy of the SGLT2i empagliflozin 25 mg oral per day each in the setting of single-hormone automated AP and conventional insulin pump therapy on the proportion of time spent in target and in hypoglycemia each during a 4-week day-and-night period. The pilot trial aims to enroll 28 adult patients with type 1 diabetes (T1D) across 2 research sites (one in Toronto and one in Montreal) and includes a 2- week therapy optimization run-in period, 4-weeks for each of the two AP intervention arms, and a 1- week washout in between the pharmacological intervention sequences. Glucose levels will be measured by continuous glucose monitoring (G5, Dexcom Inc.). Insulin will be infused using a subcutaneous infusion pump (t-slim, Tandem Diabetes Care) and communication between pumps and the algorithm will be implemented using Android Smartphone devices and Bluetooth technology communication.
