As patents on many major biologics are expected to expire by 2016, it's estimated that roughly half of the large molecule therapeutics market, representing an estimated $92B in 2010, will be open to competition from large molecule generics, often referred to as biosimilars or follow-on biologics.

Over 50 biosimilars/copy-biologics, covering a fairly limited selection of branded drugs, are in the clinic. However, most of these are restricted to emerging markets. Comparatively, only 14 biosimilar approvals have occurred in Europe and none in the United States. It is expected that biosimilar development in these markets will accelerate driven by the emergence of regulatory guidelines, the impending patent cliff and the push for cheaper medications. 

Industry Leading Biosimilars Experience

With our regulatory knowledge and experience in product characterization, pharmacokinetics and immunogenicity, for both innovator and biosimilars, we carry your project from Discovery phase through Phase III studies and beyond.
