Looking to the future and learning lessons from the recent past: changing stakeholder perceptions of biosimilars in cancer

Abstract

As the patents for many biologic anticancer drugs expire, significant growth in the use of biosimilars is predicted, offering an opportunity to help combat the rising costs of treatment and increase patient access to biologic therapy. Attainment of regulatory approval, involving numerous nonclinical and clinical comparative studies versus each reference product, is only one of several barriers to realize the potential gains offered by biosimilars. It is important to understand the current perceptions and informational needs of different stakeholders if biosimilars are to be accepted and widely used in the clinic. We discuss these considerations and refer to recent experiences with CT-P13, a biosimilar of the TNF inhibitor infliximab used to treat rheumatoid arthritis and other inflammatory disorders.
