Healthy volunteers: yes

Brief summary:
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.

Detailed description:

Arms:
arm 1: 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.

After a 5- to 14-day washout period, participants received 0.15 U/kg insulin aspart and 5 micrograms per milliliter (μg/mL) recombinant human hyaluronidase PH20 (rHuPH20) (insulin aspart-rHuPH20) coadministered as a CSII, for 4 days (Days 5-8; Period 2), including during a 6-hr euglycemic clamp on Days 6 and 8. arm 2: Participants first received 0.15 units per kilogram (U/kg) insulin aspart and 5 micrograms per milliliter (μg/mL) recombinant human hyaluronidase PH20 (rHuPH20) (insulin aspart-rHuPH20) coadministered 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.

After a 5- to 14-day washout period, participants received 0.15 U/kg insulin aspart alone as a CSII, for 4 days (Days 5-8; Period 2), including during a 6-hr euglycemic clamp on Days 6 and 8. arm 3: Participants first received 0.12 units per kilogram (U/kg) insulin aspart administered as a continuous subcutaneous insulin infusion (CSII), for 5 days (Days 1-5; Period 1), including during a 6-hour (hr) euglycemic clamp on Days 2, 3, and 5. On Day 2 only, a sham injection was administered 2.5 hr prior to the 6-hr euglycemic clamp.

After a 5- to 14-day washout period, participants received 0.12 U/kg insulin aspart administered as a CSII, for 5 days (Days 6-10; Period 2), including during a 6-hr euglycemic clamp on Days 7, 8, and 10. On Day 7 only, a 1.0-milliliter (mL) subcutaneous (SC) injection of 1.25 micrograms per milliliter (μg/mL) recombinant human hyaluronidase PH20 (rHuPH20) was administered 2.5 hr prior to the 6-hr euglycemic clamp. arm 4: Participants first received 0.12 units per kilogram (U/kg) insulin aspart administered as a continuous subcutaneous insulin infusion (CSII), for 5 days (Days 1-5; Period 1), including during a 6- hour (hr) euglycemic clamp on Days 2, 3, and 5. On Day 2 only, a 1.0-milliliter (mL) subcutaneous (SC) injection of 1.25 micrograms per milliliter (μg/mL) recombinant human hyaluronidase PH20 (rHuPH20) was administered 2.5 hr prior to the euglycemic clamp .

After a 5- to 14- day washout period, participants received 0.12 U/kg insulin aspart administered as a CSII, for 5 days (Days 6-10; Period 2), including during a 6-hr euglycemic clamp on Days 7, 8, and 10. On Day 7 only, a sham injection was administered 2.5 hr prior to the 6-hour euglycemic clamp.
