Halozyme and Roche Enter Agreement for the Application of Enhanze, A Novel Technology to Improve Drug Delivery
BASEL, Switzerland and SAN DIEGO, Dec. 5 /PRNewswire/ — Halozyme Therapeutics, Inc. (AMEX:HTI) and Roche today announced they have entered into an agreement to apply Halozyme’s proprietary Enhanze(TM) Technology to Roche’s biological therapeutic compounds. Enhanze Technology is Halozyme’s proprietary drug delivery technology based on its recombinant human hyaluronidase (rHuPH20). rHuPH20 is an analogue of a human enzyme that temporarily clears space in the matrix of tissues such as skin. This clearing activity should allow rHuPH20 to improve drug delivery by enhancing the entry of therapeutic molecules through the subcutaneous space.
“Roche is a global leader in the development of biologics and we are excited to be applying our rHuPH20 technology to this area with Roche compounds,” said Jonathan Lim, MD, Halozyme’s President and CEO. “We believe that our technology can enhance the clinical benefits that biologics have already been shown to provide. In every respect, both technically and commercially, this represents a landmark agreement for Enhanze Technology and for Halozyme.”
“We are looking forward to working together with Halozyme using their rHuPH20 technology,” said Peter Hug, Roche’s Global Head of Pharma Partnering. “The potential to improve the administration and bioavailability of subcutaneous medicines presents an important advance to make a difference to patients’ lives.”
Halozyme Roche Collaboration
Under the terms of the agreement, Roche will pay 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 as well as royalties on potential product sales 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. In addition, the Roche Venture Fund will make an $11 million equity investment, representing approximately 5% of Halozyme’s outstanding common stock.
Under the collaboration, Roche will also obtain access to Halozyme’s expertise in developing and applying rHuPH20 to Roche targets. Roche will obtain a worldwide, exclusive license to develop and commercialize product combinations of rHuPH20 and Roche target compounds resulting from the collaboration.
About Enhanze Technology
Enhanze Technology is Halozyme’s proprietary drug delivery technology based on recombinant human hyaluronidase (rHuPH20), a recombinant form of the naturally occurring human enzyme approved by FDA for its ability to break down hyaluronic acid (HA), the space-filling “gel”-like substance that is a major component of tissues throughout the body. When combined or co-formulated with certain injectable drugs, Enhanze Technology can act as a “molecular machete” to facilitate the penetration and dispersion of these drugs by temporarily opening flow channels under the skin. Molecules as large as 200 nanometers may pass freely through the perforated extracellular matrix, which recovers its normal density within approximately 24 hours, leading to a drug delivery platform which does not permanently alter the architecture of the skin.

About Halozyme
Halozyme is a biopharmaceutical company developing and commercializing recombinant human enzymes for the drug delivery, palliative care, oncology, and infertility markets. The company’s portfolio of products is based on intellectual property covering the family of human enzymes known as hyaluronidases. Halozyme’s recombinant human enzymes may replace current animal slaughterhouse-derived extracts that carry potential risks of animal pathogen transmission and immunogenicity. The company has received FDA approval for two products: Cumulase(R), the first and only recombinant human hyaluronidase for cumulus removal in the IVF process; and Hylenex for use as an adjuvant to increase the absorption and dispersion of other injected drugs. The versatility of the first enzyme, rHuPH20, enables Halozyme to develop the product as a medical device, drug enhancement agent, and therapeutic drug.
