Our Biosimilars

Our Products

Pfenex’s protein production platform and bioanalytical approach to developing biosimilars enables the potential for a fingerprint-like identity to a reference product limiting the need for extensive and costly clinical trials. Utilizing our core technology, Pfenex Expression Technology for recombinant protein production, we are able to rapidly develop and produce high-quality therapeutics.

The Pfenex product pipeline currently contains eight biosimilars and one therapeutic equivalent candidate. The 2014 global biologics market represented over $230 billion in product sales with virtually the entire market comprised of branded innovator products. We believe the emerging biosimilar market will be fueled by the large number of blockbuster products facing patent expiry in the next several years, abbreviated regulatory pathways for the approval of biosimilars, and a mandate for lower drug costs by governments and private payers.

Our lead biosimilar candidate is PF582, a biosimilar candidate to Lucentis (ranibizumab). Lucentis, marketed by F. Hoffmann-La Roche and Novartis AG, for the treatment of retinal diseases, achieved approximately $3.6 billion in 2015 global sales.

Our wholly owned candidates include PF530, a biosimilar candidate to Betaseron (interferon beta-1b) marketed by Bayer AG for the treatment of multiple sclerosis that achieved global sales of $0.9 billion in 2015. We are also developing PF708, a therapeutic equivalent to Forteo (teriparatide), for the treatment of high-risk fracture patients. In addition, PF529, a biosimilar candidate to Neulasta (pegfilgrastim), and PF688, a biosimilar candidate to Cimzia (certolizumab-pegol) are also in development.

We also have a product partnership with Strides Acrolab, a specialty pharma company located in Bangalore, India. This includes PF444, a biosimilar candidate to human growth hormone, PF694, a biosimilar candidate to Pegasys (peginterferon alpha-2a), and PF690, a biosimilar candidate to Oncaspar (pegaspargase).
