EXPERIMENTAL: LY2605541 Fixed Time Dosing
Participant-specific dose of LY2605541 administered subcutaneously (SQ) at approximately the same time every evening for 12 weeks in the Lead-in Period and in Randomization Period 1 or Randomization Period 2. Participant-specific dose of insulin lispro SQ when >20% of calories were consumed (pre-meal). Insulin dose and adjustments to insulin dose were determined by insulin algorithms based on self-monitored blood glucose (SMBG). Target glucose values were as follows: Preprandial and bedtime BG between 71 and 130 milligrams/deciliter (mg/dL) Insulin adjustment and glucose correction between 71 and 100 mg/dL. |
Other Names:
All participants will be administering insulin lispro SQ as their pre-meal insulin during the course of the trial.
|
EXPERIMENTAL: LY2605541 Variable Time Dosing
Participant-specific dose of LY2605541 administered SQ on a variable time schedule (8- and 40-hour dosing intervals) for 12 weeks in Randomization Period 1 or Randomization Period 2. Dosing schedules were to remain approximately the same throughout the 12 weeks. Participant-specific dose of insulin lispro SQ when >20% of calories were consumed (pre-meal). Insulin dose and adjustments to insulin dose were determined by insulin algorithms based on SMBG. Target glucose values were as follows: Preprandial and bedtime BG between 71 and 130 mg/dL Insulin adjustment and glucose correction between 71 and 100 mg/dL. |
Other Names:
All participants will be administering insulin lispro SQ as their pre-meal insulin during the course of the trial.

Measure Description |
Time Frame |
---|---|---|
Hemoglobin A1c (HbA1c) at 12 Weeks
Time Frame: At 12 Week in Each Randomization Period
|
HbA1c is a test that measures a person's average blood glucose level over the past 2 to 3 months.
Least Squares (LS) means were calculated using a mixed model repeated measures (MMRM) analysis including the following fixed effects: treatment, period, sequence, baseline HbA1c (last nonmissing value at or before randomization), week (defined from the start of each Randomization Period), and treatment-by-week interaction.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
30-Day Adjusted Rate of Total and Nocturnal Hypoglycemic Events
Time Frame: Baseline (Day 1) of Randomization Period through 24 Weeks (12 weeks in each Randomization Period)
|
Total hypoglycemic events (HE) include any event based on a blood glucose <=70 milligrams per deciliter (mg/dL) (3.9 millimoles per liter [mmol/L]), with or without signs/symptoms of hypoglycemia or an event associated with signs/symptoms of hypoglycemia but without a glucose measurement.
Nocturnal HE include any total HE that occurred between bedtime and waking.
Group Means are presented and were calculated from negative binomial regression models (number of episodes = treatment + period + treatment sequence + baseline HbA1c [<=8.0%
or >8.0%], with log [exposure in days/30] as an offset variable).
Group Mean (LS mean) is estimated by taking the inverse link function on individual participant covariates first and then averages over all participants.

Baseline (Day 1) of Randomization Period through 24 Weeks (12 weeks in each Randomization Period)
|
Percentage of Participants With Total and Nocturnal Hypoglycemic Events
Time Frame: Baseline (Day 1) of Randomization Period through 24 weeks (12 weeks in each Randomization Period)

Total HE include any event based on a blood glucose <=70 mg/dL (3.9 mmol/L), with or without signs/symptoms of hypoglycemia or an event associated with signs/symptoms of hypoglycemia but without a glucose measurement.
Nocturnal HE include any total HE that occurred between bedtime and waking.
The percentage of participants was calculated by dividing the number of participants with hypoglycemic episodes by the total number of participants analyzed, multiplied by 100.
