Purpose of review: The field of HER2-positive breast cancer has seen tremendous advances in the last 2 years with largest number of new drugs in decades. The present review aims to summarize the cutting-edge research of the past 2 years and future directions.
Recent findings: This review will go over four new drugs, three of which have gained FDA approval within the past 18 months, in the treatment of HER2-positive breast cancer. We will go over early and mature clinical data on these therapeutics and ongoing clinical trials further exploring their role in the treatment of patients with advanced HER2-positive breast cancer and HER2 low breast cancer. Will also discuss ongoing trials using immunotherapy and CDK4/6 inhibitors in the advanced HER2-positive setting.
Summary: : The therapies described in this review have quickly become standard of care for patients with HER2-positive breast cancer. Furthermore, they have the potential to change the landscape of breast cancer therapy further to include even patients with HER2 low breast cancer.
Trial registration: ClinicalTrials.gov NCT02448420 NCT02947685.
