A Randomized, Controlled, Crossover Trial to Assess a Fully Automated, Dual-hormone (Insulin-and-pramlintide) Delivery System Without Carbohydrate Counting in Regulating Glucose Levels in Adults With Type 1 Diabetes.
The aim of this clinical trial is to investigate whether a fully automated Lyumjev-and-pramlintide delivery system improves glycemic outcomes in adults with type 1 diabetes. The main question we aim to answer is whether a Lyumjev-pramlintide fully closed loop system improves time in range compared to a hybrid closed loop system with carbohydrate counting. We also aim to find the optimal insulin to pramlintide ratio for glycemic control in the fully automated system. In this cross-over study, patients will undergo the following three interventions in a random order: (i) fully automated Lyumjev insulin-and-pramlintide (8 μg/u) (ii) fully automated Lyumjev insulin-and-pramlintide (10 μg/u) (iii) rapid automated Lyumjev insulin-and-placebo with carbohydrate-matched boluses For all interventions, participants will be required to wear two Ypsomed pumps programmed by our developed EuGlide system.
• Individuals ≥ 18 years of age.
• A clinical diagnosis of type 1 diabetes for at least 12 months. The diagnosis of type 1 diabetes relies on the investigator's judgment; C peptide level and antibody determinations are unnecessary.
• Using insulin pump therapy for at least three months.
• Individuals of childbearing potential using an effective birth-control method. An individual of childbearing potential must agree to use a highly effective method of birth control.
