Biosimilar approvals and patent litigation in the US

Biosimilars/General | Posted 19/02/2021 0 Post your comment

Authors from Law360 have examined biosimilar approvals by the US Food and Drug Administration (FDA) under the Biologics Price Competition and Innovation Act of 2009 (BPCI Act) and ensuing patent litigation actions. They also discuss why the lack of new approvals and litigation in 2020 does not suggest reduced interest in biosimilars but signals a new wave of biosimilars on the horizon [1].

In the US, the BPCI Act was signed into law on 23 March 2010, giving FDA the authority to approve biosimilars. FDA then issued guidelines for biosimilar applications in February 2012 in the form of three draft guidance documents [2] and has since issued many other guidance documents relevant for biosimilars [3].

FDA approved its first biosimilar Zarxio (filgrastim-sndz) in 2015 [4] and has progressively approved more biosimilars each year. To date (January 2021), FDA has approved 29 biosimilars [plus four follow-on biologicals: [5]. Of these 29 biosimilars, only an estimated 18 have entered the US market, according to authors Whitehill and Deshmukh.

According to a 2020 IQVIA report, biosimilars could save the US healthcare system US$100 billion over the next five years [6]. However, despite this fact, the number of biosimilar approvals fell in 2020 to just three compared to 2019 when there were a record 10 approvals [5]. Although, on the bright side only five BPCI Act litigation cases remained pending as of 31 December 2020.

The following series of articles discusses in more detail biosimilar approvals and launches in the US and biosimilar patent litigation in the country.
