HALOZYME THERAPEUTICS PROVIDES AN UPDATE ON ANTICIPATED MILESTONES FOR 2014 AT THE 32ND ANNUAL J. P. MORGAN HEALTHCARE CONFERENCE

SAN DIEGO, January 13, 2014 - Halozyme Therapeutics, Inc. (NASDAQ: HALO) today provided an update on the anticipated milestones for its product development programs in 2014.

"Halozyme is poised for a pivotal year in 2014," stated Dr. Helen Torley, President and Chief Executive Officer. "With multiple collaboration products advancing to commercialization stage, our focus is now on advancing and unlocking the value of our three proprietary products, which are potentially game-changing for the company. There are a number of key development and commercialization events over the next twelve months that can be used to measure our progress."

"For PEGPH20, these include completion of enrollment of the Phase 2 pancreatic cancer study (Study 202) and initiation of a study to evaluate PEGPH20 in an additional tumor setting. With respect to our diabetes program, we plan to communicate results from the CONSISTENT 1 study of Hylenex as a pre-treatment in patients with diabetes using insulin pumps in the first quarter of 2014. In support of maximizing the commercial potential of Hylenex as a pre-treatment in patients with diabetes using insulin pumps, in the coming weeks, we will be seeking input from the FDA regarding the path for a labeling update to include key efficacy and safety data prior to initiating promotion for this use. For HTI-501, we look forward to communicating top-line results from our cellulite trial also in the first quarter of 2014."
