Olaparib
Jan 2018 (Food and Drug Administration, FDA): As monotherapy for use in patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer who have been previously treated with chemotherapy in the neoadjuvant, adjuvant or metastatic setting (patient selection using an FDA-approved companion diagnostic for olaparib) [1, 2]. Patients with hormone receptor-positive breast cancer should have been treated with a prior endocrine therapy or be considered inappropriate for endocrine treatment.
April 2019 (European Medicines Agency, EMA): As monotherapy for use in patients with germline BRCA1/2-mutations who have HER2-negative locally advanced or metastatic breast cancer and have previously been treated with an anthracycline and a taxane in the (neo)adjuvant or metastatic setting (unless patients were not suitable for these treatments) [3]. Patients with hormone receptor-positive breast cancer should also have progressed on or after prior endocrine therapy or be considered unsuitable for endocrine therapy.
Talazoparib
Oct 2018 (FDA): As monotherapy treatment of adult patients with deleterious or suspected deleterious gBRCAm human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer (patient selection using an FDA-approved companion diagnostic for talazoparib) [4, 5].
In April 2019, talazoparib received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP). EMA approval is pending.
