FDA receives application for monoclonal antibody biosimilar Posted 29/08/2014

South Korean biotechnology company Celltrion announced on 11 August 2014 that the company had, on 8 August 2014, completed the filing procedure to obtain US Food and Drug Administration (FDA) approval for its infliximab biosimilar.

This marks the first 351(k) biosimilar monoclonal antibody application to be filed in the US and the second application for a biosimilar to be filed through the US Biologics Price Competition and Innovation Act of 2009.

Sandoz, the generic drug division of Swiss drug giant Novartis, was the first company to submit an application under the biosimilars pathway, when it submitted its application for approval of the company’s biosimilar filgrastim product on 24 July 2014 [1].

Celltrion is seeking approval for Remsima (infliximab), a biosimilar of Johnson & Johnson’s (J&J) blockbuster anti-inflammatory treatment Remicade (infliximab). Remicade had worldwide sales of US$6.7 billion during 2013, according to a J&J financial statement.

Barring any setbacks, Celltrion anticipates obtaining FDA approval within one year. Once approved, Celltrion would still only be able to launch its biosimilar once the patent on Remicade expires in the US, which is currently set to be in September 2018 [2]. However, in order to pave the way for the introduction of its biosimilar, Celltrion has filed a lawsuit claiming that patents on the originator drug Remicade (infliximab) are invalid and unenforceable [3].

Celltrion has already obtained approval for Remsima from over 50 countries worldwide, including most of advanced regulatory agencies including Europe, Canada and Japan.
