KEYTRUDA (pembrolizumab) and KEYTRUDA QLEX (pembrolizumab and berahyaluronidase alfa-pmph) are the first FDA-approved PD-1 inhibitors available as part of a complete treatment regimen for eligible patients with platinum-resistant ovarian cancer.ii

Approximately 80% of individuals with ovarian cancer experience recurrence after initial therapy, and many develop resistance to platinum-based chemotherapy, leading to limited treatment options and poor survival outcomes. The approval of KEYTRUDA and KEYTRUDA QLEX in this setting introduces meaningful new treatment options that have been found to reduce the risk of disease progression and improve overall survival.iii Labcorp's nationwide availability of PD-L1 IHC 22C3 pharmDx enables clinicians to quickly identify patients who may benefit from these newly approved treatments.
