FDA Approval in BRCA Mutated HER2-negative High-Risk Early Breast Cancer

The FDA approved olaparib as an adjuvant treatment in patients with deleterious or suspected deleterious germline BRCA mutated HER2-negative high-risk early breast cancer who were pretreated with neoadjuvant or adjuvant chemotherapy, according to a press release.

Olaparib is a PARP inhibitor. The recommended dose of olaparib is 300 mg orally twice daily for up to one year. 

This approval was based on results from the OlympiA trial of 1,836 patients with gBRCA mutated HER2-negative high-risk early breast cancer. The primary efficacy endpoint was invasive disease-free survival. 

After 3 years, invasive disease-free survival for patients receiving olaparib was 86% and just 77% for patients on placebo.
When looking at overall survival, there were 75 deaths in the olaparib arm compared to 109 deaths in the placebo arm. 

Olaparib demonstrated a statistically significant improvement in both invasive disease-free survival and overall survival when compared to placebo.
