AstraZeneca and MSD's Lynparza (olaparib) has been recommended for marketing authorisation in the European Union (EU) as monotherapy or in combination with endocrine therapy for the adjuvant treatment of adult patients with germline BRCA1/2 mutations (gBRCAm) who have HER2-negative high-risk early breast cancer previously treated with neoadjuvant or adjuvant chemotherapy. The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency based its positive opinion on results from the OlympiA Phase III trial published in The New England Journal of Medicine in June 2021. In the trial, Lynparza demonstrated a statistically significant and clinically meaningful improvement in invasive disease-free survival (iDFS), reducing the risk of invasive breast cancer recurrences, new cancers, or death by 42% versus placebo (based on a hazard ratio [HR] of 0.58; 99.5% confidence interval [CI] 0.41-0.82; p<0.0001).

Lynparza also demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS), reducing the risk of death by 32% versus placebo (based on a HR of 0.68; 98.5% CI 0.47-0.97; p=0.009). The safety and tolerability profile of Lynparza in this trial was in line with that observed in prior clinical trials. Breast cancer is the most diagnosed cancer worldwide with an estimated 2.3 million patients diagnosed in 2020.2 Approximately 90% of all breast cancer patients are diagnosed with early breast cancer.

In Europe, BRCA mutations are found in up to 10% of patients.
