• Introduction: Approval of the HER2-targeted antibody trastuzumab dramatically improved outcomes for patients with HER2-positive breast cancer. Multiple trastuzumab biosimilars, including ABP 980, are in clinical development. Biosimilars are not identical to the reference biologic, but exhibit equivalence and safety in analytical and clinical studies. Areas covered: A brief introduction to trastuzumab, overview of trastuzumab biosimilars, and detailed review of ABP 980 preclinical and clinical studies are included. We searched PubMed and 2016-2017 ASCO and ESMO conference proceedings for 'ABP 980' or 'trastuzumab biosimilar'. 'ABP 980 and breast cancer' or 'trastuzumab biosimilar and breast cancer' were used to search clinicaltrials.gov for phase III trials. Analytical studies of ABP 980 pharmacokinetics (PK) or pharmacodynamics (PD), phase I studies of ABP 980 safety and PK/PD, and phase III studies of clinical efficacy vs trastuzumab are included. Expert opinion: Questions remain regarding long-term impact of biosimilars on overall healthcare costs, insurance coverage of multiple approved biosimilars, and extensive clinical safety and efficacy follow-up. By producing a competitive market, trastuzumab biosimilars are anticipated to improve access to standard of care therapies, although real-world evidence remains to be obtained. Increased global access to HER2-targeted therapy may eventually alter the landscape of breast cancer and survival rates.
