Randomized, Double-blind, Crossover, Pharmacokinetic (PK) and Glucodynamic (GD) Study of Continuous Subcutaneous Insulin Infusion (CSII) in Participants With Type 1 Diabetes Mellitus (T1DM)
Randomized, Double-Blind, Pharmacokinetic (PK) and Glucodynamic (GD) Crossover Study of Continuous Subcutaneous Insulin Infusion (CSII) of Rapid Acting Insulin Analogs With and Without Recombinant Human Hyaluronidase (rHuPH20)
The purpose of this study is to determine if recombinant human hyaluronidase PH20 (rHuPH20) will change the exposure and action of approved insulin analogs when given by continuous subcutaneous insulin infusion (CSII) in participants with Type 1 diabetes mellitus (T1DM).
This study is divided into Stage 1, 2, and 3. Stage 3 was started chronologically before Stage 2 and, prior to performing Stage 2, the Sponsor made the decision to terminate Stage 2. Stage 2 was not initiated due to a strategic business decision and termination was not based on safety or efficacy concerns. No participants were enrolled in Stage 2.

Active Comparator: Stage 1: Insulin aspart first, then insulin aspart-rHuPH20
Participants first received 0.15 units per kilogram (U/kg) insulin aspart administered as a continuous subcutaneous insulin infusion (CSII), for 4 days (Days 1-4; Period 1), including during a 6-hour (hr) euglycemic clamp on Days 2 and 4.
