Summary: Ziextenzo (LA-EP2006) is a biosimilar version of pegfilgrastim (reference product, Neulasta by Amgen) that is manufactured by Sandoz. A biologic license application for approval via the 351(k) biosimilar pathway was originally submitted to the Food and Drug Administration (FDA) in December 2015, with final approval given in November 2019. Sandoz launched the drug immediately following approval. This agent, like all other biosimilar pegfilgrastim candidates, was subject to complete response letters from the FDA. Its 351(k) application was resubmitted in April 2019. Sandoz set its initial price at a 37% discount in wholesale acquisition cost discount relative to Neulasta.
About the Manufacturer
Sandoz, although established as a division of Novartis in 2003, has its origins as an active player in the pharmaceutical industry in 1886. It has a considerable portfolio of biosimilar products approved by the FDA and in various stages of filing. Besides Ziextenzo, Sandoz has obtained FDA approvals for Zarxio (filgrastim-sndz), Hyrimoz (adalimumab-adaz), and Erelzi (etanercept-szzs). Sandoz has withdrawn its biosimilar rituximab from consideration for FDA approval (though also approved in the EU). The company also markets a biosimilar infliximab in the EU.
