Halozyme Therapeutics, Inc. is a biotechnology company, which is focused on developing and commercializing oncology therapies that target the tumor microenvironment. The Company’s development pipeline consists primarily of clinical-stage product candidates in oncology and diabetes. The product candidates in its pipeline are based on rHuPH20, a human recombinant hyaluronidase enzyme. rHuPH20 temporarily breaks down hyaluronic acid (HA). Its lead oncology program is PEGPH20 (PEGylated recombinant human hyaluronidase), a new molecular entity, under development for the systemic treatment of tumors that accumulate HA. The Company is in collaboration with pharmaceutical companies including, Roche, Pfizer, Janssen and Baxter for its drug delivery platform, ENHANZE, which enables biologics and small molecule compounds that are administered intravenously to be delivered subcutaneously.
