Primary Outcome Measures:
  • Glycosylated Hemoglobin A1C (HbA1c) at Endpoint [ Time Frame: After 16 weeks of each treatment (Periods1 and 2) ] [ Designated as safety issue: No ]
    Hemoglobin A1c (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over the last 8-12 weeks. Least Squares (LS) means were adjusted for treatment, period, sequence, thiazolidinedione use (Yes/No), baseline HbA1c (>8% or ≤8%) and participants.


Secondary Outcome Measures:
  • Total Daily Insulin Dose [ Time Frame: Week 16 of each treatment (Periods 1 and 2) ] [ Designated as safety issue: No ]
    Total daily insulin dose was the average of the last 3 days total insulin dose immediately prior to the Week 16 (endpoint) visit of each treatment period. Least Squares (LS) means were adjusted for treatment, period, sequence, thiazolidinedione use (Yes/No), baseline Hemoglobin A1c (HbA1c) (>8% or ≤8%) and participants.

  • Rate of Hypoglycemic Events Per 30 Days [ Time Frame: Baseline through 16 weeks of each treatment (Periods 1 and 2) ] [ Designated as safety issue: Yes ]
    A hypoglycemic episode is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia, or has blood glucose concentration of ≤70 milligrams/deciliter [mg/dL (3.9 millimoles/liter (mmol/L)]. Least Squares (LS) means were adjusted for treatment, period, sequence, baseline hypoglycemic event rate, thiazolidinedione use (Yes/No) and baseline Hemoglobin A1c (HbA1c) (>8% or ≤8%).

  • Change From Baseline in Weight [ Time Frame: Baseline, Week 16 of treatment Periods 1 and 2 ] [ Designated as safety issue: Yes ]
    Least Squares (LS) means were adjusted for treatment, period, sequence, thiazolidinedione use (Yes/No), baseline Hemoglobin A1c (HbA1c) (>8% or ≤8%), baseline weight and participants.

  • Percentage of Participants With Hypoglycemic Events [ Time Frame: Baseline through 16 weeks of each treatment (Periods 1 and 2) ] [ Designated as safety issue: Yes ]
    A hypoglycemic episode is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia, or has blood glucose concentration of ≤ 70 milligrams/deciliter [mg/dL (3.9 millimoles/liter (mmol/L)]. The percentage of participants is the total number of participants experiencing hypoglycemic events divided by number of participants in the treatment arm multiplied by 100.

Detailed Description:

This study will provide clinical information on the use of insulin lispro in continuous subcutaneous insulin infusion (CSII) in participants with type 2 diabetes. This study is designed to allow comparison of the 2 rapid-acting insulin analogs, with regard to their efficacy and safety, when used as a pump insulin therapy in this participant population. Each participant will be randomized to 1 of the 2 sequence groups in a 1:1 ratio and randomization will be stratified according to screening A1C (less than or equal to 8.0% or greater than 8.0%) and thiazolidinedione (TZD) use (yes or no). The study design includes the following periods: Screening/Randomization, Treatment Period 1 (16 weeks), and Treatment Period 2 (16 weeks).

  Eligibility

  • Are receiving chronic (lasting longer than 2 weeks) systemic glucocorticoid therapy (excluding topical, intraocular, intraarticular, and inhaled preparations) or have received such therapy within 2 weeks immediately before screening
  • Have had more than 1 episode of hypoglycemia (defined as requiring assistance of a third party due to disabling hypoglycemia) within 6 months prior to entry into the study
