Terminology is also important, they add, and the researchers “use the term ‘bioequivalence’ as a sort of all-encompassing comparability term.” It is easy, they add, “to conflate concepts of bioequivalence, biosimilarity, interchangeability, and therapeutic equivalence.”
Thus, they conclude, “We encourage further exploration of mechanisms to ensure common understanding of these concepts among the drug development, regulatory, clinical practice, patient, and payer communities.”
