Halozyme Therapeutics, Inc.

Halozyme develops an enzyme technology that makes it easier to deliver injectable medicines under the skin instead of into a vein. The company either sells this enzyme as an ingredient to other pharmaceutical companies or partners with them to add it to existing drugs. They also make and sell some injectable medicines themselves, including a testosterone replacement therapy called XYOSTED and several cancer and immunology treatments. The company works with major pharmaceutical firms including Roche, Pfizer, AbbVie, and Eli Lilly to improve how their drugs are administered to patients.
