In May, the FDA approved three interchangeable biosimilars that were the first for their reference drugs. With an additional three approvals in June, that brings the total number of biosimilars to 57 since the agency’s green lighting of Sandoz’s Zarxio (filgrastim-sndz) on March 6, 2015. With the three agents approved in May also gaining interchangeability status, that brings the count of interchangeable biosimilars to 15. While the market is certainly heating up, it still is grappling with issues such as expected rebates, maintains one industry expert.
On May 20, the FDA approved the first biosimilars of Regeneron Pharmaceuticals, Inc.’s Eylea (aflibercept): Biocon Ltd. subsidiary Biocon Biologics Ltd.’s Yesafili (aflibercept-jbvf) and Samsung Bioepis Co., Ltd. and Biogen Inc.’s Opuviz (aflibercept-yszy). On June 28, the FDA approved a third Eylea biosimilar, Formycon AG and Klinge Biopharma GmbH’s Ahzantive (aflibercept-mrbb) for the same indications as the first two agents, but it does not have interchangeable status.
