Celltrion/Pfizer Inflectra Second US Biosimilar; Many Firsts

Move over Zarxio. There's a new kid in town: Inflectra (infliximab-dyyb), which won the FDA's nod on April 5 as the first monoclonal antibody biosimilar licensed in the US, although it's going to be a while before patients have access to the new drug, since Celltrion Inc. and Pfizer Inc. said they won't put it on the market until after June 29.
