There is obviously a market for biosimilars. This is driven by the cost savings to be made by payers and patients alike. By 2015, IMS Health (IMS) expects spending on biosimilars to exceed US$2 billion annually, or about 1% of total global spending on biologicals. They expect new biosimilars to enter the US market by 2014 and European markets to have additional biosimilar molecules introduced during this period [1].
             
            
                                    
                                
Biosimilars have been on the market since 2006 and are already present in many countries worldwide, see Table 1 [2].

The first biosimilars approved were human growth hormone, followed by erythropoietin (EPO) and granulocyte colony-stimulating factor (G-CSF).
Global sales of biosimilars have more than doubled each year since 2007, and had reached more than US$234 million in 2010, see Figure 1. EPOs take the major share of the market with sales of US$93 million, followed by G-CSF (US$75 million) and human growth hormone (US$67 million). Despite the dominance of EPOs, Sandoz’s Omnitrope—a human growth hormone—is still the largest selling biosimilar, with global sales in 2010 of US$66 million.

The biosimilars market is clearly experiencing rapid growth and looks set to reach IMS’s predictions exceeding US$2 billion annually by 2015.
