INTRODUCTION

In 2010, Congress streamlined Food and Drug Administration (FDA) approval of versions of biologic drugs made by other manufacturers (“biosimilars”) after market exclusivity expiration. This pathway, codified in section 351(k) of the Public Health Service Act, was intended to leverage existing knowledge about originator biologics to require fewer trials. By reducing cost of entry, policymakers incentivized competition and lower drug prices.

Biosimilar market growth, however, has been slow.1 The FDA approved its first biosimilar in 2015.2 As of February 2019, 17 biosimilars of 9 originator biologics had received regulatory approval, but only 7 had been marketed with limited price reductions.3 Concern has arisen whether biosimilar testing requirements have hindered market entrants, leading some to doubt that the US biosimilar marketplace will eventually flourish.4

Europe has had more experience with biosimilars than the USA. The European Medicines Agency (EMA) approved its...
