A Study of Glucose Control in Participants With Type 1 and Type 2 Diabetes

Meal-centric Insulin Dosing for Optimized Post-Prandial Glucose Control in People Using Multiple Daily Injections

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 (T1D) and type 2 diabetes (T2D). No study drug will be given. The study will last about 18 weeks.

• Insulin pen use for at least 3 months
• Current use of or willingness to use Dexcom G6 at least 6 out of 7 days per week
• A1c 6.5-9.5%

Exclusion Criteria:

• Currently using any form of insulin pump, including hybrid closed-loop system (e.g., Medtronic 670G)
• Individuals requiring single insulin boluses of >40 units
• Individuals planning to follow a specific diet plan for weight loss
