Assessment of Mealtime Bolus Insulin Behavior
June 12, 2019 updated by: Eli Lilly and Company
An Objective Assessment of Mealtime Bolus Insulin Behavior and Associated Factors
The main purpose of this study is to estimate missed bolus insulin doses in diabetics.
This is a 12-week, single-arm, outpatient, exploratory study with two study periods in Type 1 or Type 2 diabetics, with an investigational reusable injection pen, insulin, and a Continuous Glucose Monitoring (CGM) device.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Average Number of Days Per Month With a Missed Bolus Insulin Dose With Blinded CGM
Time Frame: Week 1 up to 6 weeks
|
The average number of days per month with a missed bolus insulin dose was calculated in participants with Type 1 Diabetes or Type 2 Diabetes using blinded CGM measurements and the pen.
The time of insulin dosing and glucose excursions were assessed using the display times recorded by the pen and CGM devices, respectively.

Average Number of Days Per Month With a Missed Bolus Insulin Dose With Unblinded CGM
Time Frame: Week 6 up to 12 weeks
|
The average number of days per month with a missed bolus insulin dose was calculated in participants with Type 1 Diabetes or Type 2 Diabetes using unblinded CGM measurements and the pen.
The time of insulin dosing and glucose excursions were assessed using the display times recorded by the pen and CGM devices, respectively

Percentage of Time-in-Range (Glucose >70 and ≤180 Milligrams Per Deciliter) With Blinded CGM
Time Frame: Baseline up to 6 weeks
|
Percentage of time-in-range (glucose >70 and ≤180 milligrams per deciliter) was calculated in participants with Type 1 Diabetes or Type 2 Diabetes based on blinded CGM data collected in the study period.
