South Korean biopharmaceutical company Celltrion Inc. submitted a BLA to the U.S. FDA on March 10 to gain approval for its Xolair (omalizumab; Novartis AG) biosimilar, CT-P39, across major indications of asthma, food allergy and chronic spontaneous urticaria.
The biosimilars revolution continues with the U.S. FDA’s approval of the first denosumab biosimilars: Wyost (denosumab-bbdz) and Jubbonti (denosumab-bbdz) from Sandoz Inc. for treating osteoporosis and to prevent bone problems in cancer. The approval puts up a strong challenge to Amgen Inc.’s Prolia, the first biologic for osteoporosis, and Xgeva, for bone cancer.
Amid intensifying competition in the PD-1/PD-L1 checkpoint space, Samsung Bioepis Co. Ltd. kicked off a phase I study of SB-27, a biosimilar of Merck & Co Inc.’s blockbuster immunotherapy, Keytruda (pembrolizumab), for lung cancer. Posted on clinicaltrials.gov on Feb. 20, the randomized, double-blind, three-arm, parallel group and multicenter phase I study will examine the pharmacokinetics, efficacy and safety of SB-27 against an EU-sourced and U.S.-sourced Keytruda in 135 patients with non-small-cell lung cancer.
Abbvie Inc.’s blockbuster drug Humira is getting a 10th challenger that could give all the other adalimumab biosimilars a run for their money – depending on pricing and formulary coverage, of course. After delays caused by the COVID-19 pandemic and manufacturing issues, the U.S. FDA approved Simlandi, previously known as AVT-02, as a Humira biosimilar and interchangeable Feb. 23.

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).
