CONSISTENT 1 Trial Results Presented in Late-Breaker Poster

SAN DIEGO, June 15, 2014 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) today presented a scientific poster highlighting the CONSISTENT 1 trial results at the 74th Scientific Sessions of the American Diabetes Association in San Francisco. The CONSISTENT 1 trial is evaluating Hylenex® recombinant and a new formulation of Hylenex currently under U.S. Food and Drug Administration (FDA) review, when used as pretreatment of the insulin infusion site in patients with type 1 diabetes (T1DM) receiving continuous subcutaneous insulin infusion (CSII) in comparison to no pre-treatment. Data reported in the presentation show that the study's primary endpoint of non-inferiority for A1C at six months between the use of Hylenex and the new formulation of Hylenex in comparison to no pre-treatment was met.  In addition to other trial data, the poster also presents data indicating that there was a potential reduction in the rate of hypoglycemic events associated with the use of the Hylenex formulations in comparison to no pre-treatment.

Additional Study Details
The CONSISTENT 1 (CONtinuous Subcutaneous Insulin infusion STudy ENrolling Type 1 Diabetes) trial is evaluating the safety and efficacy of Hylenex® recombinant and a new formulation of Hylenex under FDA review in a six month trial with an 18 month extension phase in 455 patients with type 1 diabetes. The primary efficacy endpoint is comparison of change from baseline in A1C levels at six months. Secondary endpoints are hypoglycemia rates, hyperglycemia comparisons, glucose variability and safety endpoints including adverse events, local tolerability and immunogenicity.

About Hylenex® recombinant (hyaluronidase human injection)
Hylenex® recombinant is a tissue permeability modifier indicated as an adjuvant to increase the dispersion and absorption of other injected or subcutaneously infused drugs, to facilitate subcutaneous fluid administration and in subcutaneous urography. Hylenex recombinant is contraindicated in patients with a known hypersensitivity to recombinant human hyaluronidase or any excipient used to make the drug. 

The most frequently reported adverse reactions with Hylenex recombinant have been local injection site reactions, such as erythema and pain. For additional information or full Prescribing Information visit www.hylenex.com or www.halozyme.com.
