Halozyme Therapeutics Completes Enrollment of INFUSE-LR, a Hylenex Clinical Trial of Subcutaneous Hydration

Results Expected to be Presented at The Annual American Academy of Hospice and Palliative Medicine Conference in February

SAN DIEGO, Jan. 24 (HSMN NewsFeed) -- Halozyme Therapeutics, Inc. (Amex: HTI ), a biopharmaceutical company focused on the development and commercialization of recombinant human enzymes, today announced it has completed enrollment of a clinical trial of subcutaneous (SC) hydration (hypodermoclysis) with Hylenex. Hylenex is a liquid injectable formulation that includes the active pharmaceutical ingredient, recombinant human hyaluronidase (rHuPH20), which is approved by the U.S. Food and Drug Administration (FDA) for use as a spreading agent to increase the absorption and dispersion of other injected drugs. Subcutaneous hydration is the introduction of fluids under the skin to replace inadequate intake or excessive loss of water and electrolytes during illness or operation.

The INcreased Flow Utilizing Subcutaneously-Enabled Lactated Ringer's clinical trial, or INFUSE-LR study, is designed to determine the subcutaneous infusion flow rate of lactated Ringer's solution with and without Hylenex, assess the subcutaneous infusion flow rate dose response to Hylenex over one order of magnitude of dose, and assess safety and tolerability. Lactated Ringer's solution is a widely used fluid for intravenous rehydration. The double-blind, randomized, placebo-controlled, dose-comparison study reached its target enrollment of 50 evaluable subjects. Results are expected to be presented at the 2006 American Academy of Hospice and Palliative Medicine's Annual Assembly in Nashville, TN, February 8-11, 2006.

About Hylenex

Hylenex recombinant (hyaluronidase human injection) is indicated for use as an adjuvant agent to increase the absorption and dispersion of other injected drugs, for hypodermoclysis, and as an adjunct in subcutaneous urography for improving resorption of radiopaque agents. Hylenex recombinant is contraindicated in patients with hypersensitivity to hyaluronidase enzyme or any other ingredients in the formulation. The contraindications and warnings regarding the use of Hylenex should be recognized and adhered to prior to prescription or administration.
