Questions and Answers

What is a key criterion for a biosimilar to resemble the reference product?

  • Therapeutic equivalence
  • Pharmacokinetic similarity
  • Chemical similarity
  • Structural and functional similarity (correct)

    • What type of study is necessary to validate the similar safety and effectiveness of both the biosimilar and the reference product?
