The purpose of the study is to compare Humalog (Insulin lispro)-recombinant human hyaluronidase (rHuPH20) or Novolog (Insulin aspart)-rHuPH20 to Humalog (Insulin lispro) for the treatment of Type 1 Diabetes Mellitus (T1DM) in basal-bolus therapy.
Criteria for randomization into the study included 1) fasting blood glucose and predinner glucose values in the range of 70 to 140 milligrams per deciliter (mg/dL) approximately 60% of the time for 7 days prior to randomization 2) 90 minute or 2-hour postprandial blood glucose \<220 mg/dL approximately 70% of the time for 7 days prior to randomization and 3) successfully completed 3 days of 10-point glucose monitoring and have at least 4 self-monitored blood glucose values on all non-10-point monitoring days. Participants that did not meet 1 or more of these criteria during a 4- to 6-week Titration Period were not randomized.

Change From Baseline in Glycosylated Hemoglobin A1C (HbA1c) at the End of Each Treatment Period
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.
Time frame: Baseline, Week 12 and Week 24
Mean Daily Insulin Dose
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).
Time frame: Week 10 and Week 22
Percentage of Participants Meeting Glucose Targets
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).
Time frame: Baseline through Week 24, excluding 10-point glucose monitoring days

Rates of Hypoglycemia at the End of Each Treatment Period
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.
Time frame: Week 12 and Week 24
Change From Baseline in Body Weight at the End of Each Treatment Period
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).
Time frame: Baseline, Week 12 and Week 24
Mean Daily Postprandial Glucose (PPG) Excursions
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.
Time frame: Week 10 and Week 22
