On October 16, 2018, the FDA approved PARP-inhibitor talazoparib (Talzenna®, Pfizer) for use in patients with deleterious or suspected deleterious germline BRCA-mutated locally advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Patients should be selected for the PARP inhibitor (PARPi)-treatment using an FDA-approved companion diagnostic (CDx) for talazoparib.
Single-agent PARP-inhibition with talazoparib is associated with an improved progression-free survival (PFS) and better patient-reported outcomes (PRO) when compared to chemotherapy alone in patients with advanced breast cancer (ABC) and a germline BRCA1/2 mutation, as reported by the investigators of the Phase III EMBRACA study (NCT01945775) in the New England Journal of Medicine.
Breast cancer: a front-runner when it comes to the development of novel therapeutic strategies. With the advent of newer targeted- and immunotherapies, oncologists have an increment of options to offer their patients. The American Society of Clinical Oncology’s (ASCO) 2018 Breast Cancer track offered an extensive look at the latest advancements and updates from on-going trials covering the various subtypes of breast cancer.
