Inflectra (infliximab-dyyb), Pfizer/Celltrion’s Remicade biosimilar, became the first monoclonal antibody biosimilar to enter the U.S. market in late November 2016. In this series, we track Inflectra’s awareness and uptake since launch, to understand how its entry will shape the evolving U.S. immune biologics market. Along with awareness, familiarity, and perceptions of biosimilars in general, and Inflectra specifically, the research also explores the drivers and barriers behind uptake of biosimilars/Inflectra. Promotional efforts are explored, as well as prescriber and nonprescriber profiles, and benchmarking comparisons against other available biosimilars, to better understand the dynamics of the U.S. biosimilars market.
