Simple Summary Considering the high incidence and mortality of breast cancer, a lot of trials evaluating new drugs for the treatment of this disease are currently ongoing. However, few drugs show a statistically and clinically significant improvement in the outcomes leading to the Competent Authority approval. In this review we analyzed the European Medicines Agency breast cancer drug indications issued between January 2015 and June 2021 and we evaluated the clinical trials results leading to the approval and their update. Breast cancer represents the first cause of cancer worldwide and the leading cause of cancer mortality for women. Therefore, new therapies are needed to improve the prognosis of women diagnosed with this disease. In this review, we summarize the new drug indications for the treatment of breast cancer approved by European Medicines Agency between January 2015 and June 2021. In particular, we analyzed the clinical trials results leading to approvals and their update (when available), according to setting (localized and locally advanced or metastatic) and clinical features (hormone receptor positive, HER2 positive, triple negative, BRCA 1/2 mutation). The aim of this paper is to describe the clinical benefit obtained with the new indications.
