Summary: Truxima is the first FDA-approved biosimilar version of rituximab (reference product, Rituxan) manufactured by Genentech.
Originally designated CT-P10 by its manufacturer, Celltrion, which submitted a biologic license application for approval via the 351(k) biosimilar pathway in June 2017. The Food and Drug Administration (FDA) rejected the application in April 2018. Celltrion resubmitted to FDA the following month. It was recommended for approval in October 2018 by the FDA’s Oncology Drug Advisory Committee, and approved in November 2018.
About the Manufacturer
Celltrion was founded in 2002 in Incheon, South Korea. Its first biosimilar product was approved in 2013 by the European Medicines Agency, and Inflectra was first approved in the US in 2016. Celltrion has six other biosimilar products in development.
In October 2016, Celltrion and Teva formed a partnership, in which Teva would commercialize two biosimilars, Truxima and Herzuma (both of which are approved but not yet marketed) in the US.
