Halozyme Therapeutics Reports Fourth Quarter and Year End 2008 Financial Results

"Halozyme made significant clinical achievements in 2008, including advancing our insulin program into Phase 2 development, commencing a Phase 1 clinical trial for our bisphosphonate program, Baxter BioScience initiating a Phase 3 pivotal study for GAMMAGARD LIQUID^(TM) with PH20, and Roche starting the first clinical trial in our partnership," said Jonathan Lim, M.D., Halozyme's President and CEO. "Our decision to move forward in parallel with five proprietary and three partnered programs puts us in a strong strategic position. We have a robust, diversified portfolio of product candidates targeting significant unmet medical needs with large market opportunities that we can capture on our own or with partners."

2008 and Recent Corporate and Scientific Achievements

• A Phase 2 clinical trial in type 1 diabetic patients began in October 2008 testing four dosage regimens: Humulin^(R) R (regular human insulin) with and without PH20 and Humalog^(R) (insulin lispro) with and without PH20. The study will compare pharmacokinetics and glycemic control of a standardized liquid meal challenge and we expect to have interim results in mid-2009. At the American Diabetes Association meeting in June 2008, we presented the results of a Phase 1 study with a design similar to the currently ongoing Phase 2 trial. The Phase 1 trial demonstrated significantly faster insulin absorption, faster and greater glucose lowering activity, greater peak insulin levels, and lower variability across subjects for the two combinations of insulin with PH20 compared to either of the two insulins administered alone.
• In December 2008, Roche dosed the first patient in a Phase 1 pharmacokinetic clinical trial of a biologic directed to a Roche exclusive target with a subcutaneous formulation using Enhanze^(TM) Technology. Roche also selected a fourth exclusive target and maintained its rights to an additional nine targets covered in the existing licensing and collaboration agreement. These actions by Roche triggered an aggregate payment of $10.25 million to Halozyme. Early this year, Roche began a Phase 1 clinical trial of another Roche biologic formulated with Enhanze Technology directed against a second exclusive target. Both of these Phase 1 clinical trials are expected to conclude by mid-2009.
• The Phase 3 pivotal clinical trial with GAMMAGARD LIQUID plus Halozyme's Enhanze Technology as a single site injection under the skin for the treatment of primary immune deficiency began in the fourth quarter of 2008. Enrollment of the study, conducted by our partner Baxter BioScience, should be completed by the end of the year with results available in the second half of 2010.
• The Phase 1 clinical trial of a bisphosphonate with PH20 administered subcutaneously began in the fourth quarter of 2008. This dose ranging clinical trial is assessing the safety, tolerability and pharmacokinetics of a bisphosphonate with and without co-administration of PH20 across a range of concentrations and volumes and various PH20 doses. We expect results by the end of 2009.
• Positive preclinical animal efficacy data were presented for PEGPH20 during 2008 and in January 2009 at several scientific meetings. The studies, conducted in mouse tumor models that produce hyaluronan (HA), demonstrated that PEGPH20 removed HA from the tumor microenvironment and reduced tumor interstitial fluid pressure in a dose dependent fashion, with resultant tumor growth inhibition and prolonged time to progression compared to controls. In contrast, treatment of HA negative tumors showed no reduction of tumor pressure, no suppression of tumor volume growth, or no improvement in time to progression. We expect to begin a range finding repeat dose Phase 1 clinical trial of PEGPH20 as a single agent dosed intravenously in cancer patients with refractory solid tumors during the second quarter of 2009.

Fourth Quarter and Year End 2008 Financial Results

The net loss for the fourth quarter of 2008 was $16.8 million, or $0.21 per share, compared with a net loss for the fourth quarter of 2007 of $8.7 million, or $0.11 per share. Net loss for the year ended December 31, 2008 was $48.7 million, or $0.61 per share compared to a net loss of $23.9 million, or $0.32 per share for the year 2007.

• Revenue for the fourth quarter of 2008 was $3.1 million, compared to $1.3 million for the fourth quarter of 2007. Revenues under collaborative agreements for the fourth quarter of 2008 were $2.8 million, compared to $1.2 million for the fourth quarter of 2007. Revenues under collaborative agreements in 2008 primarily consisted of the amortization of upfront fees and a milestone payment received from Baxter and Roche of $1.6 million and research and development reimbursements from Baxter and Roche of $1.2 million.
• Research and development expenses for the fourth quarter of 2008 were $16.8 million, compared with $7.3 million for the fourth quarter of 2007, primarily due to an increase in research and development headcount, spending on the PEGPH20, insulin and bisphosphonate preclinical and clinical programs, and production costs associated with the manufacturing scale up of the rHuPH20 and PEGPH20 enzymes.
• Selling, general and administrative expenses for the fourth quarter of 2008 were $3.2 million, compared to $3.9 million for the fourth quarter of 2007, reflecting decreases in legal and professional fees, market research and recruiting expenses.
• Cash and cash equivalents were $63.7 million as of December 31, 2008, compared with $97.7 million as of December 31, 2007 and $72.5 million as of September 30, 2008. In January 2009, the company received payments of $6.0 million from Roche and $5.5 million from Baxter.

Financial Outlook for 2009

Halozyme anticipates 2009 net cash burn of approximately $30 million to $35 million, depending on the progress of various preclinical and clinical programs, the timing of our manufacturing scale up and the achievement of various milestones under our existing collaborative agreements.
