It is also used to treat HER2-overexpressing metastatic breast cancer in patients who have received one or more chemotherapy treatments.

Trastuzumab and hyaluronidase-oysk combination prevents the growth of some tumors that produce extra amounts of a certain substance known as the HER2 protein. It should only be used in patients whose tumors have been shown to produce extra amounts of this protein (HER2 overexpression).
