Update on HYLENEX® Reintroduction

On August 31, 2010, Halozyme Therapeutics, Inc. ("Halozyme") issued a press release to report on its plans for the reintroduction of HYLENEX. In addition, Halozyme announced the lifting of the notice of breach previously delivered to Baxter Healthcare International. The press release is attached as Exhibit 99.1 to this Form 8-K.

Update on United States and European Patents

On August 12, 2010, Halozyme announced the issuance of United States Patent No. 7,767,429 (the "’429 Patent") claiming its proprietary recombinant human hyaluronidase enzyme platform (rHuPH20). Claims to the human PH20 glycoprotein, PEGylated variants, the glycoprotein produced by recombinant methods, and pharmaceutical compositions with other agents, including antibodies, insulins, cytokines, anti-infectives and additional therapeutic classes were awarded in this patent and additional claims are in prosecution. This patent will not expire until September 23, 2027.

A European counterpart patent, EP1603541, was also granted to Halozyme on November 11, 2009. On August 13, 2010, Halozyme learned that an opposition to this patent was filed with the European Patent Office. Halozyme plans on contesting the opposition with written submissions to the European Patent Office. Halozyme expects to obtain European patent protection that is equal or superior to the claims recently issued in the ’429 patent. The European patent provides protection until March 5, 2024.
