March 6, 2015 was a turning point for the emerging U.S. biosimilars market. The U.S. Food and Drug Administration (FDA) approved Sandoz’s application to market Zarxio®, the first biosimilar drug in the U.S. Zarxio® (approved as “filgrastim-sndz”) is a biosimilar of Amgen’s Neupogen®, a drug with 2013 sales of $1.4bn.
