Drug: Insulin lispro mid mixture (MM)
Drug: Insulin glargine
Registration Number

Primary Outcome Measures
NameTimeMethod
Hemoglobin A1c (HbA1c) at 36 Week Endpoint36 weeks

Level of hemoglobin A1c at endpoint.

Secondary Outcome Measures
NameTimeMethod
Hemoglobin A1c (HbA1c) at Interval Visits12, 24, and 36 weeks

Levels of HbA1c at 12 weeks and 24 weeks and 36 weeks.

Percentage of Patients Who Achieved Hemoglobin A1c Less Than or Equal to 6.5%, Greater Than 6.5%, Less Than 7%, Greater Than or Equal to 7%, Less Than or Equal to 7%, and Greater Than 7% at Interval Visits and Endpoint12-24-36 weeks
7-point Self-monitored Blood Glucose ProfilesBaseline, 12-24-36 weeks

Actual daily mean blood glucose levels at specified time points.

Glycemic VariabilityBaseline, 12-24-36 weeks

Glycemic variability was measured by mean blood glucose value (M-value), which was the mean of the intra-days self-monitoring blood glucose values, and by the mean of daily difference (MODD), which was the mean of the between-days self-monitored blood glucose values.

Number of Patients With at Least One Self-reported Hypoglycemic Episode, Including Nocturnal (and Non-nocturnal) HypoglycemiaBaseline to 36 Weeks

Hypoglycemic episode defined: any time patient felt that he/she was experiencing a sign or symptom associated with hypoglycemia, or had old Roche blood glucose level \<70 mg/dL even if not associated with signs, symptoms, or treatment consistent with current guidelines. Nocturnal hypoglycemia defined: any hypoglycemic event that occurred between bedtime and waking. Non-nocturnal hypoglycemia defined: any hypoglycemic event that occurred between waking and bedtime. Overall episodes: those that occurred at any time during the post-randomization visits. Endpoint: last visit interval based on LOCF.

30-Day Adjusted Rates of Self-Reported Hypoglycemic Episodes (Including Nocturnal and Non-Nocturnal)Baseline to 36 Weeks

Hypoglycemic episode defined: any time patient felt that he/she was experiencing a sign or symptom associated with hypoglycemia, or had old Roche blood glucose level \<70 mg/dL even if not associated with signs, symptoms, or treatment consistent with current guidelines. Nocturnal hypoglycemia defined: any hypoglycemic event that occurred between bedtime and waking. Non-nocturnal hypoglycemia defined: any hypoglycemic event that occurred between waking and bedtime. Overall episodes: those that occurred at any time during the post-randomization visits. Endpoint: last visit interval based on LOCF.

Number of Patients With at Least One Severe Hypoglycemia EpisodeBaseline to 36 Weeks

Severe hypoglycemia was defined as hypoglycemic event that meets at least one of the following criteria: not capable of treating self and blood glucose \<2.8 millimoles per liter (mmol/L); not capable of treating self, blood glucose is missing and prompt recovery after oral carbohydrate or glucagon or intravenous glucose; hypoglycemic event outcome was coma, hopitalization, emergency room visit, or automobile accident. The overall category is a severe hypoglycemic event that occurred at any time during the post-randomization visits. Endpoint: last visit interval based on LOCF.

Endpoint Insulin Dose Per Body Weight; Total, Basal, and Prandial36 Weeks

Total daily insulin dose adjusted for body weight (Units of insulin per kilogram per day \[U/kg/day\]) was assessed. Basal insulin is the amount of insulin required to manage normal daily blood glucose fluctuations. Prandial insulin is taken at meal time. Insulin glargine is a basal insulin and insulin lispro is a prandial insulin. Insulin lispro mid-mix is a 50/50 mixture of a basal insulin and insulin lispro. Endpoint: last visit interval based on LOCF.

Endpoint Insulin Dose; Total, Basal, and Prandial36 Weeks

Total daily insulin dose (Units of insulin per day \[U/day\]) was assessed. Basal insulin is the amount of insulin required to manage normal daily blood glucose fluctuations. Prandial insulin is taken at meal time. Insulin glargine is a basal insulin and insulin lispro is a prandial insulin. Insulin lispro mid-mix is a 50/50 mixture of a basal insulin and insulin lispro. Endpoint: last visit interval based on LOCF.

Number of Insulin Injections Per DayWeeks 12, 24, 30, 36
Change From Baseline in Absolute Body Weight at 36 Week EndpointBaseline, 36 Weeks

Change in body weight was calculated as weight at endpoint (last observation carried forward) minus weight at baseline.
