Halozyme Therapeutics Reports Fourth Quarter and Year End 2006 Financial Results

SAN DIEGO, March 8 /PRNewswire-FirstCall/ -- Halozyme Therapeutics, Inc. (AMEX: HTI) , a biopharmaceutical company developing and commercializing recombinant human enzymes, today reported financial results for the three months and year ended December 31, 2006.

"We have had a very exciting ninety days with the announcements of our recent Roche collaboration and our expanded Baxter collaboration. These are transforming events for our Company and we are working diligently to move our various programs forward," stated Jonathan Lim, MD, Halozyme's President and CEO. "We continue to make solid progress on all fronts and are meeting our milestones, including the recent completion of our INFUSE-Morphine clinical trial and our first Enhanze(TM) Technology clinical trails."

  Fourth Quarter 2006 and Subsequent Weeks' Highlights

  *  The completion of our first Enhanze Technology collaboration with
     Roche. Under the terms of the agreement, Roche paid Halozyme
     $20 million as an initial upfront payment for the application of
     rHuPH20 to three pre-defined Roche biologic targets. Over the next ten
     years, Roche will also have the option to exclusively develop and
     commercialize rHuPH20 with an additional ten targets. Pending the
     successful completion of a series of clinical, regulatory and sales
     events, Roche may pay Halozyme further milestones which could
     potentially reach a value of up to $111 million for the first three
     targets. For each of the additional ten targets, Roche may pay Halozyme
     further upfront and milestone payments of up to $47 million per target,
     or up to $470 million.  Roche will pay Halozyme royalties on any
     potential products resulting from the collaboration.  In addition, the
     Roche Venture Fund made an $11 million equity investment, representing
     approximately 5% of Halozyme's outstanding common stock.  Roche will
     also obtain access to Halozyme's expertise in developing and applying
     rHuPH20 to Roche targets and obtain a worldwide, exclusive license to
     develop and commercialize product combinations of rHuPH20 and Roche
     target compounds.

  *  The completion of our expanded Baxter collaboration to include the use
     of HYLENEX recombinant with Baxter proprietary and non-proprietary
     small molecule drugs.  Under the terms of the agreements, Baxter paid
     Halozyme an initial upfront payment of $10 million and made a
     $20 million equity investment, representing approximately 3% of
     Halozyme's outstanding common stock.  Pending the successful completion
     of a series of regulatory and sales events, Baxter may make further
     milestone payments of up to $25 million to Halozyme.  Halozyme will
     also receive royalties on HYLENEX recombinant as a standalone product
     and on any kits and co-formulations of HYLENEX recombinant with Baxter
     or other non-proprietary small molecule drugs.  Baxter prepaid
     $1 million of these royalties in connection with the execution of the
     agreements and will be obligated to prepay $9 million of additional
     royalties on or prior to January 1, 2009.  The agreements do not
     include combinations of HYLENEX recombinant with cytostatic and
     cytotoxic chemotherapeutic agents or bisphosphonates, the rights to
     which have been retained by Halozyme.  In addition, Baxter will now
     assume all development, manufacturing, clinical, regulatory, sales and
     marketing costs.

  *  The completion of our first Enhanze Technology clinical trial with a
     representative commercially-available large protein molecule
     therapeutic (LPMT).  This clinical trial compared the
     pharmacokinetics (PK), safety and tolerability of an LPMT agent
     subcutaneously injected first without Enhanze Technology (rHuPH20) and
     then with rHuPH20 in 15 patients. The open-label, dose escalation,
     within-patient controlled study used escalating dose cohorts of rHuPH20
     (ranging from 1,600 U to 12,800 U) and substituted a standard
     subcutaneous (SC) injection of the LPMT with one SC injection of the
     LPMT agent combined with Enhanze Technology (rHuPH20). The data from
     this clinical trial support the study hypothesis that rHuPH20 increases
     the relative bioavailability of the LPMT.  For the primary endpoint of
     area under the curve (AUC) for plasma concentration of the LPMT, the
     AUC over the 14 days following injection was higher when the LPMT was
     administered with rHuPH20 compared to without rHuPH20 for 100% (15/15)
     of the patients in the study. The addition of rHuPH20 increased the AUC
     above baseline (average trough level) of the LPMT for all cohorts
     combined by an average of 58%.

  *  The completion of our INFUSE-Morphine clinical trial. Key results from
     analysis of the 12 evaluable hospice and palliative care patients in
     the trial included achieving a statistically significant acceleration
     in the average time to maximal plasma concentration (Tmax) of morphine.
     Tmax was reduced from 13.8 minutes when injected subcutaneously with
     the saline placebo to 9.2 minutes when injected with HYLENEX
     recombinant, a 33% reduction in the time to maximal plasma
     concentration (p<0.05).  The double-blind, randomized, crossover,
     placebo-controlled, INcreased Flow Utilizing Subcutaneously-Enabled
     Morphine clinical trial, or INFUSE-Morphine study, was designed to
     determine the time to maximal blood levels of morphine after
     subcutaneous administration with and without HYLENEX recombinant, to
     determine the time to maximal blood levels after intravenous
     administration of morphine, and to assess safety and tolerability.

  Fourth Quarter 2006 Financial Results

  *  Net loss for the fourth quarter of 2006 was $4.4 million, or $0.07 per
     share, compared with a net loss for the fourth quarter of 2005 of
     $3.5 million, or $0.07 per share.  Net loss for the full year 2006 was
     $14.8 million, or $0.24 per share compared with a net loss for the full
     year 2005 of $13.3 million, or $0.26 per share.

  *  Revenues for the fourth quarter of 2006 were $426,000, compared to

About HYLENEX

HYLENEX recombinant (hyaluronidase human injection) is indicated as an adjuvant to increase the absorption and dispersion of other injected drugs, as an adjuvant for subcutaneous fluid administration (hypodermoclysis), and as an adjunct in subcutaneous urography for improving resorption of radiopaque agents. Hyaluronidase is contraindicated in patients with hypersensitivity to hyaluronidase enzyme or any other ingredients in the formulation. Hyaluronidase should not be used to enhance the absorption and dispersion of dopamine and/or alpha agonist drugs. Discontinue HYLENEX recombinant if sensitization occurs. Hyaluronidase should not be applied directly to the cornea, and should not be injected around infected or acutely inflamed areas, nor used to reduce the swelling of bites or stings. Hyaluronidase should not be used for intravenous injections because the enzyme is rapidly inactivated. Furosemide, the benzodiazepines, and phenytoin are incompatible with hyaluronidase. Please see accompanying package insert for full Prescribing Information.
