Other Clinical Trial - Insulin-plus-pramlintide Closed-loop Strategy to

Status Completed

Clinical Trial Summary

Closed-loop system systems that are shown to alleviate the burden of carbohydrate counting without degrading glucose control are still lacking. In this proposal, the investigators aim to develop a novel, fully-automated, closed-loop system that delivers insulin and pramlintide that controls postprandial glucose levels without any input from the user.

Clinical Trial Description

Meal carbohydrate content is the main determinant of prandial insulin needs, and consequently, accurate carbohydrate counting is recommended for type 1 diabetes. Advances in glucose sensors have motivated the development of the closed-loop system to automatically regulate glucose levels in individuals with type 1 diabetes. In the closed-loop system, a dosing algorithm adjusts the pump insulin infusion rate based on continuous glucose sensor readings. Closed-loop system systems that are shown to alleviate the burden of carbohydrate counting without degrading glucose control are still lacking. In this proposal, the investigators aim to develop a novel, fully-automated, closed-loop system that delivers insulin and pramlintide that controls postprandial glucose levels without any input from the user. Thus, the two hormones' role in the postprandial state will be as follows: 1. Insulin: to reduce plasma glucose levels. Insulin delivery needs to be aggressive to counter-act fast increase in post-meal glucose levels. 2. Pramlintide: to slow gastric emptying and aim insulin in efficiently controlling postprandial glucose levels. The aim of this study is to assess a fully automated, dual-hormone, closed-loop system that delivers insulin, and pramlintide to control glucose levels without degrading overall glycemic control compared to an insulin-alone closed-loop system with carbohydrate-matched boluses. The investigators hypothesize that the dual-hormone closed-loop system will alleviate carbohydrate-counting burden (fully reactive system) without degrading glucose control compared to the insulin-alone closed-loop system. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
