Diabetes Mellitus, Type 1
Conditions
Brief summary
The study will be conducted in participants with type1 diabetes on insulin injection therapy to investigate how the body processes LY900014 and the effect of LY900014 on blood sugar levels. Side effects and tolerability will be documented. The study will be conducted in two parts (Part A and Part B) to achieve its objectives. Participants are expected to enroll in both parts.

Participant flow
Pre-assignment details
Two-part study compared individualized doses of LY900014 (Test) to insulin lispro (Reference). Part A: LY900014 or insulin lispro once subcutaneously (SC) before, at, or after start of meal in each of 6 periods. Minimum 1 day washout. Part B: LY900014 or insulin lispro SC before meals for 14 days. Participants were expected to complete both parts.
