Halozyme Therapeutics, Inc.

Halozyme Therapeutics, Inc. is a biopharmaceutical company headquartered in San Diego, California, with operations spanning the United States, Switzerland, Ireland, Belgium, Japan, and other international markets. At its core is the proprietary ENHANZE drug delivery platform, which utilizes a patented recombinant human hyaluronidase enzyme (rHuPH20).

This innovative technology significantly enhances the subcutaneous (under-the-skin) administration of a diverse range of injectable medicines. This includes complex biologics such as monoclonal antibodies, various other therapeutic molecules, smaller drug compounds, and even fluids. The company's leading product, Hylenex recombinant, is an rHuPH20 formulation specifically designed to facilitate subcutaneous fluid delivery for hydration.

It also plays a crucial role in improving the dispersion and absorption of other injected drugs during subcutaneous urography, and aids in the resorption of radiopaque agents. Halozyme also offers several key therapeutics leveraging its platform, including Perjeta, RITUXAN HYCELA, and MabThera SC, which are used to treat non-Hodgkin lymphoma and chronic lymphocytic leukemia (CLL).
