Breast cancer: a front-runner when it comes to the development of novel therapeutic strategies. With the advent of newer targeted- and immunotherapies, oncologists have an increment of options to offer their patients. The American Society of Clinical Oncology’s (ASCO) 2019 Breast Cancer track offered an extensive look at the latest advancements and updates from on-going trials covering the various subtypes of breast cancer.
On 4 April 2019, the US FDA approved palbociclib (Ibrance®, Pfizer) plus aromatase inhibitor or fulvestrant for the treatment of male patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer.
On July 18, 2018, the US FDA expanded the ribociclib (Kysqali©, Novartis) approval. Ribociclib plus an aromatase inhibitor as initial endocrine-based therapy is no longer limited to postmenopausal HR-positive, HER2-negative advanced or metastatic breast cancer patients alone and now includes pre- and perimenopausal women. Furthermore, the FDA has added the combination ribociclib plus fulvestrant as initial endocrine-based therapy for postmenopausal women with HR-positive, HER2-negative advanced or metastatic breast cancer.
