A Study of Technology to Improve Glucose Control in Participants With Type 1 Diabetes
August 20, 2020 updated by: Eli Lilly and Company
Technology-supported, Meal-centric, Insulin Dosing for Optimized Post-prandial Glucose Control
The main purpose of this study is to determine whether combining meal, glucose, and insulin data in a web-based system will improve management of type 1 diabetes (T1D).
No study drug will be given.
The study will last about 18 weeks.

Combined Diabetes Management Data
Participants with type 1 diabetes will use a meal tagging application (app) and fitness tracker.
They will upload these data to a web portal where they will be matched with data from their continuous glucose monitor and insulin pump.
Combined data will be used for diabetes management.
|
Meal tagging app to capture frequently eaten meals and test meals for 16 weeks.
Fitness tracker will be worn around the clock for 16 weeks.
