Brief Summary:
The goal of this study is to determine if Hylenex recombinant leads to changes in the insulin time-action profiles and glucose responses when preadministered in the setting of continuous subcutaneous insulin infusion (CSII) compared to CSII without Hylenex recombinant (sham injection).

Condition or disease Intervention/treatment Phase
Type 1 Diabetes Mellitus Drug: Rapid Acting insulin with pre-treatment of rHuPH20 Device: Sham injection Phase 4

Detailed Description:
There is a recognized need for more rapid insulin action than is available from current rapid-acting analog products. In addition, current products have inconstant absorption and action profiles over the course of infusion set life. Previous human studies of prandial insulin preparations have used co-mixtures of rHuPH20 (study drug) with insulin delivered to study participants by subcutaneous injection and have demonstrated acceleration of insulin absorption and action. CSII has been used clinically for the treatment of diabetes over the last three decades, and a previous study using a co-mixture of rHuPH20 during CSII showed that the combination resulted in a more consistent and ultrafast profile of insulin absorption and action across infusion set use as compared to rapid analog insulin alone.

Primary Outcome Measures :
  1. Part 1: Area Under the Curve (AUC) of Glucose Infusion Rate (GIR) From 0-6 Hours [ Time Frame: 0-6 hours ]
  2. Part 2: Time to Reduction in Plasma Glucose by 80 Milligrams Per Deciliter (mg/dL) Following CSII Bolus [ Time Frame: 0-10 hours ]
    Time to reduction is reported as the maximum time it took for any participant receiving each treatment sequence to achieve a reduction in plasma glucose by 80 mg/dL. During the course of the study, it became difficult to establish a stable hyperglycemic plateau with a target glucose level of 220 mg/dL, even after adjusting several operational parameters. The study was stopped early, prior to enrolling the planned 24 participants for Part 2. Thus, analysis for this endpoint was not conducted. Raw data (as a maximum) are reported.

  3. Part 3: Time to Achieve Plasma Glucose >90 mg/dL After Release of Hypoglycemic CSII Clamp [ Time Frame: 0-12 hours ]

Secondary Outcome Measures :
  1. Part 1: Time-action Profile, Assessed by GIR in Euglycemic Participants [ Time Frame: up to approximately 10 hours ]
  2. Part 1: Mean Maximum Concentration (Cmax) [ Time Frame: up to approximately 22 hours ]
  3. Part 1: Time to Achieve Maximum Concentration (Tmax) [ Time Frame: up to approximately 22 hours ]
  4. Part 1: Early Time to 50% Maximum Serum Insulin Concentration (t50%) Max [ Time Frame: up to approximately 22 hours ]
  5. Part 1: Time to 50% of Total AUC (AUC0-last) [ Time Frame: up to approximately 22 hours ]
  6. Part 1: Fractional and Absolute AUC0-1hr [ Time Frame: 0 to 1 hour ]
  7. Part 1: Fractional and Absolute AUC2hr-end [ Time Frame: 2 to approximately 22 hours ]
  8. Part 1: Area Under the Curve From Time Zero to the Last Measureable Concentration (AUC0-last) [ Time Frame: up to approximately 22 hours ]
  9. Part 1: Mean Residence Time (MRT) [ Time Frame: up to approximately 22 hours ]
  10. Part 2: Plasma Glucose Concentration Over Time [ Time Frame: up to approximately 10 hours ]
    Plasma glucose concentration over time is reported as the maximum concentration for any participant receiving each treatment sequence. During the course of the study, it became difficult to establish a stable hyperglycemic plateau with a target glucose level of 220 mg/dL, even after adjusting several operational parameters. The study was stopped early, prior to enrolling the planned 24 participants for Part 2. Thus, analysis for this endpoint was not conducted. Raw data (as a maximum) are reported.

  11. Part 2: Insulin Analog Serum Concentration as a Function of Time Following Bolus Insulin Infusion [ Time Frame: up to approximately 10 hours ]
    Insulin analog serum concentration is reported as the maximum concentration for any participant receiving each treatment sequence. During the course of the study, it became difficult to establish a stable hyperglycemic plateau with a target glucose level of 220 mg/dL, even after adjusting several operational parameters. The study was stopped early, prior to enrolling the planned 24 participants for Part 2. Thus, analysis for this endpoint was not conducted. Raw data (as a maximum) are reported.

  12. Part 3: Plasma Glucose Concentration Over Time [ Time Frame: up to approximately 12 hours ]
  13. Part 3: Insulin Analog Serum Concentration as a Function of Time Following Termination of Insulin Infusion [ Time Frame: up to approximately 12 hours ]
