Cancer is the world’s biggest killer, and the complex biological medicines used to treat it are expensive. Even the world’s richest countries will struggle with the cost of these drugs and so tackling the issue of affordable cancer care is something we need to address now. One of the solutions could be biosimilars. But what are they, do we need them and are they similar enough to the originator products to use them safely in our patients? Opinion is divided among physicians but some experts say this is down to a lack of information and education. We interviewed top biosimilars expert, Dr Paul Cornes, on this burning subject, which is dividing opinions in the field of oncology. Dr Cornes discusses the cost of biologic medicines, the introduction of biosimilars and the regulatory pathways that have been put in place to ensure safety and efficacy remains. He talks about the methods by which biosimilars can be ‘extrapolated’ across multiple indications, as well as touching on some interesting insights into the manufacturing of the biologic molecules that oncologists have been using, without question, for years.
