Safety/Efficacy Study of Subcutaneously Injected Prandial Insulins Compared to Insulin Lispro Alone in Patients With Type 2 Diabetes Mellitus

Change in glycosylated hemoglobin A1C (HbA1C) from baseline (Week 0) to end of treatment period (Week 12 and Week 24) is presented. Data are presented by combined treatment group (Lispro-recombinant human hyaluronidase PH20 (PH20) + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin lispro from both groups). Least squares (LS) means were calculated from linear contrasts of mixed effects linear models with treatment (Lispro, Aspart), PH20 (yes, no), and treatment sequence as fixed effects and participant within treatment sequence as a random effect.

Mean daily insulin dose as recorded during 10-point glucose monitoring is reported. Blood glucose values were obtained during 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) at the following timepoints: immediately prior to breakfast (fasting), 1 hour (hr) after breakfast, 2 hr after breakfast, immediately prior to lunch, 1 hr after lunch, 2 hr after lunch, immediately prior to dinner, 1 hr after dinner, 2 hr after dinner, and at 03:00. A minimum of 7 determinations were required for each day during the 3 days of 10-point glucose profiles. Prandial insulin doses were also recorded during the 10-point glucose monitoring and the mean daily insulin dose over the 3 days was calculated. Data are presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts).

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 was recorded during non-10-point glucose monitoring was recorded. The number of participants was recorded, and the percentage of participants meeting glucose targets was calculated by 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).

The rate of hypoglycemia, defined as blood glucose levels ≤70 mg/dL and <56 mg/dL, was calculated based on 4 weeks of observation prior to the end of treatment period (that is, 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 groups). 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 (Week 12 and Week 24) is presented. Data are presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin lispro from both cohorts).

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 PPG excursions during 10-point glucose monitoring for breakfast, lunch, and dinner from Treatment Period 1 or Treatment Period 2 are presented. PPG refers to the change in glucose concentration before to after a meal. Data were collected 1 and 2 hours (hr) after each meal. Data are presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (insulin lispro from both cohorts).
