Halozyme Licenses New ENHANZE Targets For $25 Million Upfront Payment, Future Milestones And Royalties

SAN DIEGO, Oct. 30, 2018 /PRNewswire/ — Halozyme Therapeutics, Inc. (NASDAQ: HALO), a biotechnology company developing novel oncology and drug-delivery therapies, today announced that it has licensed its ENHANZE® drug-delivery technology to Roche for exclusive development of a new undisclosed clinical stage therapeutic target, with an option to select two additional targets within four years.

Under terms of the agreement, Halozyme will receive an upfront fee of $25 million with the potential to earn additional payments of up to $160 million to $165 million per target subject to achievement of specified development, regulatory and sales-based milestones. Additionally, Halozyme will receive a nomination fee for each of the two additional new target nominations. Halozyme will also receive mid-single digit royalties on sales of commercialized products. The company expects to recognize the initial $25 million payment in the fourth quarter of 2018.

“I am delighted to announce another further expansion of our long-term relationship with Roche, covering the selection of these three new targets,” said Dr. Helen Torley, president and CEO. This agreement is a strong illustration of our strategy to unlock and grow ENHANZE value through supporting partners in advancing more promising targets into the clinic through the expansion of existing agreements and the addition of new ones.”

The Halozyme/Roche relationship dates back to the original global collaboration and licensing agreement for the ENHANZE technology signed in 2006. Under this agreement, Roche developed Rituxan® SC ex-U.S., Rituxan Hycela® in the U.S., Herceptin®SC ex-U.S., is awaiting an FDA action date in 2019 for Herceptin SC in the U.S., and is conducting a Phase 3 study for the fixed dose combination of Perjeta®/Herceptin SC. In addition, Roche is in Phase 1 testing with an undisclosed target. More recently, in 2017, the relationship expanded to include the right to evaluate an additional target with ENHANZE.

The Halozyme ENHANZE technology is based on a proprietary recombinant human hyaluronidase enzyme (rHuPH20) that temporarily degrades hyaluronan — a glycosaminoglycan or chain of natural sugars in the body — to aid in the dispersion and absorption of other injected therapeutic drugs. For Halozyme partners, this technology may allow for more rapid delivery of injectable medications through subcutaneous delivery.

About ENHANZE® Technology
Halozyme’s proprietary ENHANZE® drug-delivery technology is based on its patented recombinant human hyaluronidase enzyme (rHuPH20). rHuPH20 has been shown to remove traditional limitations on the volume of biologics that can be delivered subcutaneously (just under the skin). By using rHuPH20, some biologics and compounds that are administered intravenously may instead be delivered subcutaneously. ENHANZE may also benefit subcutaneous biologics by reducing the need for multiple injections. This delivery has been shown in studies to reduce health care practitioner time required for administration and shorten time for drug administration.
