Halozyme Therapeutics, Inc. Announces FDA 510(k) Clearance For MediCult’s SynVitro Cumulase Product

SAN DIEGO, May 23 /PRNewswire-FirstCall/ -- Halozyme Therapeutics, Inc. (Amex: HTI - News), a biopharmaceutical company developing and commercializing recombinant human enzymes, today announced that its worldwide distribution partner, MediCult A/S, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for SynVitro® Cumulase® for the treatment of oocytes to facilitate certain in vitro fertilization (IVF) procedures. The media-formulated SynVitro Cumulase product contains the active pharmaceutical ingredient found in Cumulase®-10X, the first and only recombinant human hyaluronidase approved in the United States for cumulus removal in the IVF process.

“We are thrilled that our distribution partner MediCult has received FDA 510(k) clearance to market SynVitro Cumulase in the U.S.,” said Jonathan Lim, MD, Halozyme’s President and CEO. “This achievement is another key milestone for our company and provides further validation of our technology and our team’s ability to develop and commercialize products based on recombinant human hyaluronidase, whether by ourselves or through our partners.”

SynVitro Cumulase is a formulation of rHuPH20 (recombinant human PH20 hyaluronidase) prepared in MediCult’s proprietary SynVitro media, and is ready to use in ex vivo IVF procedures. This product may replace bovine and ovine extracts currently used for the preparation of oocytes prior to IVF during the process of intracytoplasmic sperm injection (ICSI). The enzyme is an essential component of ICSI and removes the hyaluronic acid that surrounds the oocyte, allowing the clinician to then perform ICSI, injecting the sperm into the oocyte. SynVitro Cumulase provides the IVF specialist with yet another safer, purer and more effective alternative to slaughterhouse-derived extracts.

The total Cumulase market consists of an estimated 500,000 ICSI cycles worldwide in 2005, with nearly 90,000 of those performed in the U.S. Halozyme received CE Mark approval of Cumulase-10X in December 2004 to market the product throughout the European Union. In April 2005, Halozyme received 510(k) clearance from the FDA to market the 10X product in the U.S. Together, Cumulase-10X and SynVitro Cumulase are the first and only recombinant human hyaluronidase products approved for cumulus removal in the IVF process.
