To the Editor: The SAME study affirmed the safety and efficacy of switching between originator and biosimilars and the potential for cost savings.1 Yet the global uptake of biosimilars has been relatively slow2 due to a number of factors, including marketing suggesting that such drugs are less safe or efficacious than the originator.3 Implicated in such marketing is confusion arising from the use of the word “interchangeable”, which is a defined term under United States legislation. The word “substitution” is used in Australia, which raises the likelihood of further confusion.
