International Society of Oncology Pharmacy Practitioners global position on the use of biosimilars in cancer treatment and supportive care.

With the development of innovative cancer treatments over recent decades, the cost of cancer care has risen exponentially, limiting patient access to patented originator biotherapeutics in many countries. The introduction of biosimilars to the market has created new opportunities as well the need for changes in practice within healthcare institutions. A ‘biosimilar’ is a biotherapeutic product which is highly similar in terms of quality, safety and efficacy to an already licensed originator product.
