The Sept. 4, 2015, at-risk launch of Sandoz Inc.’s Zarxio as the first biosimilar to hit the U.S. market came several months after the FDA had approved the filgrastim biosimilar due to a court battle over the requirements of the 2010 Biologics Price Competition and Innovation Act, which laid out the rules of the road for the new class of follow-on drugs. Ten years later, biosimilar developers are still struggling with some of those rules that were drafted by Congress in an effort to balance competition with innovation in the biologics space. Insulin biosimilars may be the hardest hit.
It’s been a decade since Sandoz Inc. launched Zarxio, referencing Amgen Inc.’s Neupogen (filgrastim), as the first biosimilar in the U.S. Zarxio was expected to be the beginning of a biosimilar boom that would deliver big savings by finally providing direct competition for costly biologics. Neither the pipeline nor the uptake of biosimilars has lived up to expectations, as only 6% of the 313 biologics approved by the FDA’s CDER have been targeted by biosimilars and fewer than 5% are actually competing with the follow-ons.
Sandoz Inc. came out the big winner Nov. 18 when the U.S. Court of Appeals for the Federal Circuit wiped out $39 million in infringement damages a jury had awarded to Allergan plc. Sandoz overcame “the doubly high burden of persuading us to overturn a jury verdict of no invalidity,” the appellate court said in its precedential opinion.
Ten years after the first biosimilar launched on the U.S. market, the FDA is taking steps to make biosimilar development and pharmacy substitution more like that of generics, reducing the cost of the drugs in the process. “We want to see more biosimilars. We want to see more competition,” FDA Commissioner Marty Makary said at an Oct. 29 media briefing in which he announced new guidance to streamline biosimilar development, cut through the red tape and shorten the timeline.
It’s taken nearly a decade for the U.S. FDA to go from zero to 60 in approving biosimilars. Currently, 63 biosimilars have been approved in the U.S., thanks to 18 new approvals in 2024 that stretched the number of biologics referenced by biosimilars from 14 to 17. That’s an all-time record, CDER Director Patrizia Cavazzoni said, as she released the drug center’s annual approval report for 2024.
A growing foray of pharmacy benefit managers’ (PBMs) private labels into the U.S. biosimilar space is intensifying concerns about the antitrust aspects of PBMs’ vertical integration that has them serving as price negotiator, formulary setter, payer, group purchasing organization, pharmacy, provider and now drug "manufacturer."
The U.S. Court of Appeals for the Federal Circuit reined in a district court that invalidated three claims in an Astellas Pharma Inc. patent protecting bladder drug Myrbetriq (mirabegron) based on a issue that was never argued.

Although last year’s massive U.S. launch of Humira biosimilars captured headlines, the market adoption of those competitors has been nothing to write home about, even with discounts as low as 85% off the innovator price.
