Two biosimilar approvals in less than a month have extended Pfizer Inc.’s already dominant position in the US biosimilars space, bringing the big pharma’s tally of 351(k) biologics license application approvals to seven – accounting for almost one-third of the FDA’s total of 23 approvals using the biosimilar pathway.
The FDA approved Pfizer’s Ruxience (rituximab-pvvr) on 23 July 2019 after clearing the company’s Zirabev (bevacizumab-bvzr) on 27 June.
