Truxima (rituximab), Celltrion’s MabThera biosimilar, became the first oncology monoclonal antibody biosimilar to enter the European market in April 2017. Two months later, Sandoz’s Rixathon, a second MabThera biosimilar, launched in Europe. In this series, we track awareness and uptake of Truxima and Rixathon since launch to understand how their entry will impact the NHL, CLL, and immune biologics market. Along with awareness, familiarity, and perception of Truxima and Rixathon, our analysis looks at the drivers and barriers behind uptake of these agents. Promotional efforts are explored, as well as prescriber and nonprescriber profiles, and benchmarking against other biosimilars, to better understand the dynamics of the German biosimilars market.
