Speakers suggest ways to eliminate barriers to biosimilar uptake, but Janssen pushes back, saying there is need to inform physicians and patients of a biosimilar's interchangeability status. Biosimilar advocates want prescriber incentives, labeling changes, and FDA education on interchangeability.
Payers are driving the selection of reference products or biosimilars, creating an ‘artificial interchangeability’ unlikely to be affected by the actual regulatory designation, industry reps say; former FDA commissioner Scott Gottlieb says misinformation campaigns around biosimilar and interchangeable products may lead to enforcement by the FDA and Federal Trade Commission.
