Lynparza (olaparib) [product information]. EMA. The European Medicines Agency (EMA) has authorized olaparib as a monotherapy for the treatment of adult patients with germline BRCA1/2-mutations, who have HER2-negative locally advanced or metastatic breast cancer. Patients should 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. Patients with hormone receptor (HR)-positive breast cancer should also have progressed on or after prior endocrine therapy, or be considered sunsuitable for endocrine therapy.
Lynparza (olaparib) [product information]. EMA. The European Medicines Agency (EMA) has authorized olaparib as both a monotherapy and in combination with endocrine for the adjuvant treatment of adult patients with germline BRCA1/2-mutations who have HER2-negative, high risk early breast cancer previously treated with neoadjuvant or adjuvant chemotherapy. Lynparza's product information cites the OlympiA trial, where olaparib was compared against placebo for the treatment of patients with germline BRCA1/2 mutated and HER2-negative high risk early breast cancer.
