Type 1 Diabetes
Conditions
Brief summary
In this study, participants with type 1 diabetes (T1D) will take the study drug LY900014 and insulin degludec. The reason for this study is to evaluate the amount of time with glucose values within target range.

|---|---|
| LY900014 + Insulin Degludec LY900014 (100 U/mL) is a prandial insulin administered SC 0-2 minutes before meals. Insulin degludec (100 U/mL) is a basal insulin administered once daily SC. Participants received individually adjusted insulin doses during the 35-day titration period. The target glucose values were: fasting glucose 80-110 mg/dL, overnight glucose excursion (the difference between bedtime and prebreakfast glucose levels) \< or = +/- 30 mg/dL, postprandial glucose peak \<140 mg/dL or \<20% increase from premeal level. Following the titration period, there was an 11-day maintenance period during which the doses were kept unchanged unless for safety reasons. | 31 |
