Purpose
The purpose of this study is to evaluate consistency of accelerated insulin absorption and onset-of-action and shortened duration of action for bolus insulin infusions after pretreatment with 150 U of Hylenex® recombinant (hyaluronidase human injection)(rHuPH20) at the time of infusion set insertion compared to sham injection.

| Official Title: | A Phase 4, Randomized, Double-Blind, 2-Way Crossover Study of Continuous Subcutaneous Insulin Infusion (CSII) With, Compared to Without, Pretreatment With Recombinant Human Hyaluronidase (rHuPH20) |
- Insulin absorption assessed by the amount of insulin exposure within the first hour following bolus insulin infusion. [ Time Frame: 0-60 minutes ] [ Designated as safety issue: No ]The primary endpoint will be insulin absorption as assessed by the amount of insulin exposure within the first one hour following bolus insulin infusion expressed as a fraction of the total insulin exposure during the six hour euglycemic clamp.
- Glycemic Excursions with and without pre-treatment with Hylenex recombinant. [ Time Frame: 72 Hours ] [ Designated as safety issue: No ]Demonstrate reduced glycemic excursions, greater proportions of subjects reaching postprandial clinical targets, safety, tolerability of the SC infusion of rapid acting insulin with and without pre-treatment with Hylenex recombinant.
- Changes in insulin absorption with and without pre-treatment with Hylenex recombinant. [ Time Frame: 72 hours ] [ Designated as safety issue: No ]Demonstrate changes in insulin absorption, safety, tolerability of the SC infusion of rapid acting insulin with and without pre-treatment with Hylenex recombinant.

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 subjects by subcutaneous injection and have demonstrated acceleration of insulin absorption and action. Continuous subcutaneous insulin infusion (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. The present study will evaluate the ability of rHuPH20 pretreatment to confer a consistent ultrafast profile of absorption and action to rapid analog insulin products across the life of infusion sets.

- Routine use of CSII as the primary route of insulin administration for at least three months prior to screening
- Subject should be in good general health based on medical history and physical examination, without medical conditions that might prevent the completion of study drug infusions and assessments required in this protocol.
Exclusion Criteria:
- Known or suspected allergy to any component of any of the study drugs in this trial.
- Previous enrollment in this trial
- Use of drugs that may interfere with the interpretation of trial results or are known to cause clinically relevant interference with insulin action, glucose utilization, or recovery from hypoglycemia. Subjects taking maintenance doses of blood thinners (e.g. Coumadin or heparin) will be excluded.
