Biosimilars Are Picking Up Market Share, but Some Uncertainties Still Exist
Since the FDA’s approval of the first biosimilar — Zarxio (filgrastim-sndz) from Sandoz, a division of Novartis Pharmaceuticals Corp. — on March 6, 2015, the agency has approved almost 40 more agents via the 351(k) pathway established under the Biologics Price Competition and Innovation Act (BPCIA), itself part of the Affordable Care Act (ACA). Although not all of those agents have launched yet, and almost all of the ones that have are all professionally administered, industry experts say they expect to see more competition in the space, depending on interchangeability status, provider uptake and the impact of the Inflation Reduction Act.
