Description: This online learning activity will discuss the science of biological products, including size, complexity, and variation. We will describe commonalities between biosimilars and reference biological products and differences in the approval pathways, with an in-depth explanation of the scientific and regulatory concepts for biosimilars and interchangeable biosimilars. In addition, we will discuss the use of these products, including labeling, terminology, and pharmacy substitution. To enhance understanding, we will review case studies to highlight the data that can support biosimilarity and interchangeability. This webinar will also demonstrate the functionality of the Purple Book Database and highlight resources available to health care providers about biosimilars.
  • Review the key definitions, nomenclature, labeling, issues of interchangeability, and similarities and differences between biosimilars and reference biologics.
  • Describe how biologics differ from small molecules (size, complexity, inherent variation) and compare the biosimilar and generic approval pathways.
  • Explain the statutory requirements and approval process for biosimilars and interchangeables.
  • Discuss considerations for prescribing and dispensing biosimilars and interchangeable biosimilars.
  • Summarize the new resources available for health care providers and faculty to learn more about biosimilar and interchangeable products and how to use the Purple Book Database of Licensed Biological Products.
