Primary Outcome Measures:
  • Change From Baseline in Glycosylated Hemoglobin A1C (HbA1c) at the End of Each Treatment Period [ Time Frame: Baseline, Week 12 and Week 24 ] [ Designated as safety issue: No ]
    Glycosylated hemoglobin A1C (HBA1c) levels were measured at baseline (Week 0) and at the end of each treatment period (Week 12 and Week 24). Data are presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts). Least Squares (LS) means were calculated from mixed effects linear models with treatment (Lispro, Aspart), recombinant human hyaluronidase PH20 (rHuPH20; yes, no), and treatment sequence as fixed effects and participant within treatment sequence as a random effect.


Secondary Outcome Measures:
  • Mean Daily Insulin Dose [ Time Frame: Week 10 and Week 22 ] [ Designated as safety issue: No ]
    Prandial insulin doses were recorded during 10-point glucose monitoring for a total of 3 days during each treatment period (3 days during Week 10 of Treatment Period 1 and 3 days during Week 22 of Treatment Period 2). The mean daily insulin dose over the 3 days during each treatment period is presented. Data is presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts).

  • Percentage of Participants Meeting Glucose Targets [ Time Frame: Baseline through Week 24, excluding 10-point glucose monitoring days ] [ Designated as safety issue: No ]
    Participants were instructed to monitor their blood glucose levels a minimum of 4 times per day on all non-10-point glucose monitoring days. The number of participants meeting 90-minute postprandial plasma glucose (PPG) targets of <140 and <180 milligrams per deciliter (mg/dL) for at least 2/3 of values during non-10-point glucose monitoring days was recorded. The percentage was calculated by dividing the number of participants with values meeting the specified target at least 2/3 of the time by the total number of participants analyzed, multiplied by 100. Data is presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts).

  • Rates of Hypoglycemia at the End of Each Treatment Period [ Time Frame: Week 12 and Week 24 ] [ Designated as safety issue: No ]
    Overall rates of hypoglycemia (blood glucose ≤70 milligrams per deciliter [mg/dL] and <56 mg/dL) were calculated based on 4 weeks of observation for each treatment period. Data is presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts). A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

  • Change From Baseline in Body Weight at the End of Each Treatment Period [ Time Frame: Baseline, Week 12 and Week 24 ] [ Designated as safety issue: No ]
    Body weight was measured at baseline (Week 0) and at the end of each treatment period (Week 12 and Week 24). Data is presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts).

  • Mean Daily Postprandial Glucose (PPG) Excursions [ Time Frame: Week 10 and Week 22 ] [ Designated as safety issue: No ]
    Participants performed 10-point glucose monitoring for a total of 3 days during each treatment period (3 days during Week 10 of Treatment Period 1 and 3 days during Week 22 of Treatment Period 2). Mean daily postprandial plasma glucose (PPG) excursions (referring to the change in blood glucose levels from before to after a meal) during 10-point glucose monitoring for breakfast, lunch, and dinner are presented. Data were collected 1 and 2 hours (hr) after each meal for 3 days and the means of each excursion are presented.

Arms Assigned Interventions
Experimental: Lispro-PH20 / Insulin Lispro

All enrolled participants underwent a titration period of 4-6 weeks in which they received 100 units per milliliter (U/mL) insulin glulisine, injected subcutaneously (SC), pre-meals, with doses titrated to each participant individually.

Next participants were randomly assigned to 1 of 2 study treatments (Treatment A or B) for the first of two, 3-month treatment cycles. Each participant then received the second treatment for the second cycle with no washout period.

Lispro-PH20 (Treatment A): 100 U/mL insulin lispro with 5.0 micrograms per milliliter (µg/mL) recombinant human hyaluronidase PH20, injected SC, pre-meals, with doses titrated to each participant individually

Insulin Lispro (Treatment B): 100 U/mL insulin lispro, injected SC, pre-meals, with doses titrated to each participant individually

Throughout the study, participants requiring basal insulin used twice daily SC injections of 100 U/mL insulin glargine.

Participants that did not meet 1 or more of these criteria during a 4- to 6-week Titration Period were not randomized.
