A Phase IIIB Dose Comparison Study of Subcutaneous Hydration With and Without Human Recombinant Hyaluronidase (HYLENEX) in Volunteer Subjects

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00311519

Brief Summary:
The purpose of this research study to test the effectiveness of a study medication to increase how fast a solution called lactated Ringer’s is absorbed when put under the skin subcutaneously. The medication to be studied is an enzyme called hyaluronidase, and is a human recombinant form of the enzyme. The drug company name for this medication is Hylenex. Hylenex was currently an investigational medication at the initiation of the study, but received FDA approval during the study. An investigational medication is a medication or formulation of a medication that is not approved by the United States Food and Drug Administration for use in this country but may be used in studies such as this one.

Primary Outcome Measures :
  1. Average infusion flow rate (mL/hr) derived from the time to infuse 400 mL of lactated ringers

Secondary Outcome Measures :
  1. Average SC infusion rate of flow (mL/hr) derived from time required to drain 400 mL from the 500 mL infusate bag, fluid and tubing AND for the arm circumference to return to baseline
  2. Flow rate determined by weight of infusate bag, fluid and tubing at specified timepoints
  3. For SC infusions, change in arm circumference in three locations in the vicinity of the site of infusion
  4. For SC infusions, time from the beginning of infusion until arm circumference returns to baseline
  5. Subject assessment of local discomfort by placing a mark on a 0 100 mm visual analogue scale (VAS) anchored by no discomfort and worst possible discomfort
  6. Local edema assessed by the Investigator on a 0-4 scale
  7. Leakage of fluid at angiocatheter site assessed by the Investigator on a 0-4 scale, prior to infusion, at mid-infusion, at end of infusion, and (for SC infusions), when arm circumference returns to baseline
  8. Subject's global rank-ordered preference for infusion
  9. Investigator's global rank-ordered preference for infusion
  10. Photographic images of the SC infusion sites
  11. Safety and tolerability, based on adverse events and PE including vital signs
