The EMA has once again come in behind the U.S. FDA, granting market access to 77 new products in 2023, fewer than half the 157 approvals the FDA processed in the 11 months from January through December 2023.
Biosimilars grabbed a lot of headlines in 2023, thanks to the biggest U.S. biosimilar launch to date targeting Abbvie Inc.’s mega-blockbuster Humira (adalimumab). Eight biosimilars referencing the immunology drug entered the U.S. market under licensing agreements with Abbvie. Amgen Inc.’s Amjevita led the pack with a five-month headstart in January. The others – including the first adalimumab interchangeable, Boehringer Ingelheim GmbH’s Cyltezo – launched in July.
In another step that blurs the distinction between biosimilars and interchangeables, the U.S. Centers for Medicare & Medicaid Services (CMS) is proposing a rule to give Medicare Part D plans more flexibility to substitute biosimilars for the reference biologics so Medicare beneficiaries can have timelier access to the lower-cost drugs. The rule would permit the plans to treat the biosimilar substitutions as “maintenance changes” that don’t require prior Medicare approval. Such changes would enable the substitutions to apply to all enrollees – and not just those who begin the therapy after the effective date of the change.
Instead of the two-step process that’s been the typical path for interchangeables in the U.S., Amgen Inc.’s Wezlana got a green light Oct. 31 from the FDA as both the first approved biosimilar and interchangeable to Johnson & Johnson’s inflammatory disease drug, Stelara (ustekinumab).
Biologics innovators typically take a lifecycle approach to developing new indications and formulations of their prescription drugs, especially when biosimilar competition is on the horizon.
As South Korea increases its stakes on the “bioeconomy” as its next growth engine and as its “second semiconductor industry,” leading domestic biologic and biosimilar drug producers such as Samsung Biologics Co. Ltd. and Celltrion Inc. are setting record production targets to become forerunners in the global playing field.
With Tofidence (tocilizumab-bavi), a monoclonal antibody from Biogen Inc., the U.S. FDA has approved the first biosimilar to the Roche Group AG’s Actemra (tocilizumab), a blockbuster with declining numbers. Tofidence was greenlighted Sept. 29 for treating rheumatoid arthritis in adults, and for treating polyarticular and systemic juvenile idiopathic arthritis in those ages 2 and older. It’s also the first biosimilar approved to treat systemic juvenile idiopathic arthritis.
National support for the biosimilar sector and the domestic industry’s efforts to increase production and sales may not be enough for South Korean biosimilar firms to box out competition in the ever-changing regulatory court of the U.S.
National support for the biosimilar sector and the domestic industry’s efforts to increase production and sales may not be enough for South Korean biosimilar firms to box out competition in the ever-changing regulatory court of the U.S. “Competition in U.S. negotiations and rebates are fierce,” Choi Sung-ho, chairman of the Korean Society for Bioeconomy, said. “Even if you get listed, it is crucial to be placed in an advantageous class to lower out-of-pocket costs.
