ESMO Biosimilars Portal

Welcome to the ESMO Biosimilars Portal

Biosimilars are medicinal products containing a similar version of the active substance of their biological originator or reference product and are derived from living organisms.

ESMO’s position is that biosimilars present a necessary and timely opportunity as they can positively impact the financial sustainability of healthcare systems while improving access to medicines for patients. Moreover, biosimilars could, in part, help address economic challenges that healthcare decision-makers are confronted with.

It is therefore important that all key stakeholders - including prescribers, pharmacists, nurses, patients, reimbursing bodies and manufacturers - understand the complexities of biosimilars and ensure that patients are being prescribed the safest and most efficacious treatment possible.
