The study's overarching aim is to determine whether Enzymatically Augmented Subcutaneous Infusion (EASI) can assist in out-of-hospital situations characterized by mismatch between need for, and ability to achieve, access to the vascular compartment. One mechanism for providing access to the vascular compartment, subcutaneous infusion, is facilitated by administration of hyaluronidase; the hyaluronidase hydrolyzes hyaluronan the major subcutaneous diffusion barrier. Hyaluronidase thus increases local dispersion and absorption of subcutaneously administered drugs and fluids.

The EASI Access study is intended to be the first out-of-hospital study assessing FDA-approved Chinese hamster ovary-derived recombinant hyaluronidase (the recombinant product is hereafter referred to by the shorter brand name, Hylenex). The EASI Access will test some fundamental principles and will facilitate design and implementation of follow-up investigations (e.g. extension of access to non-ALS providers). For example, we will attempt to show that EASI access is simple, effective, and has few or no downsides as compared to IV access.
