Immunotherapies targeting immune checkpoint inhibitors have changed the landscape of cancer treatment, however, many patients are resistant or refractory to immunotherapy. The sensitivity of tumor cells to immunotherapy may be influenced by hyaluronan (HA) accumulation in the tumor microenvironment (TME). Enzymatic degradation of HA by pegvorhyaluronidase alfa (PEGPH20; PVHA) remodels the TME.
