In lieu of pending guidance, the U.S. FDA’s approval May 20 of Biocon Biologics Ltd.’s Yesafili and Samsung Bioepis Co. Ltd.’s Opuviz as interchangeable biosimilars to Regeneron Pharmaceuticals Inc.’s Eylea (aflibercept) provides further insight into how the agency is approaching the market exclusivity the Biologics Price Competition and Innovation Act awards to the first approved interchangeable for any given biologic.
Having addressed the manufacturing issues that resulted in a few complete response letters, Alvotech Holdings SA and Teva Pharmaceutical Industries Ltd.’s biosimilars partnership is now on a roll, with the U.S. FDA approving the team’s second biosimilar, Selarsdi, less than two months after approving the first one, Simlandi, as an adalimumab interchangeable.
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.
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.
If the U.S. FDA has its way, biosimilars and interchangeable biosimilars would no longer be a difference with a distinction – at least when it comes to labeling. Instead of distinguishing between the two, the agency is recommending that the labeling for both follow-ons include a “biosimilarity statement.”
Now that the U.S. FDA has nearly 15 years of experience with developing and implementing a biosimilar pathway, it’s time for that regulatory path to catch up with the science, according to experts that have been involved in biosimilar development even before Congress passed the Biologics Price Competition and Innovation Act that created the framework for the U.S. biosimilar market.
One of the companies wanting to be part of the upcoming U.S. launch of Humira biosimilars is instead exploring options to raise additional capital so it can continue advancing its biosimilar pipeline in the near term. Alvotech Holdings SA, a pure-play biosimilars company based in Iceland, initially had hoped for FDA approval June 28 for AVT-02, developed as both an interchangeable and biosimilar to the high-concentration formulation (HCF) of Abbvie Inc.’s blockbuster autoimmune drug, Humira (adalimumab).
With the biggest biosimilar launch in the U.S. just days away, Humira’s (adalimumab) record-breaking ride is quickly slowing down, but the Abbvie Inc. mega-blockbuster immunology drug is nowhere near the end of its road. Meanwhile, the U.S. journey is just beginning for the eight adalimumab biosimilars that could come to market as early as July 1 through licensing agreements with Abbvie. Besides revving their engines against Humira, the new launches will be looking to overtake Amgen Inc.’s biosimilar, Amjevita, which got a five-month headstart in the U.S., thanks to the first-mover status Amgen earned for being the first to sign a licensing agreement with Abbvie.
A lot of biosimilar sponsors and wannabes will be watching as the Humira biosimilar competition unfolds in the U.S. While the competition started Jan. 31 with the launch of Amgen Inc.’s Amjevita, the true test of the strength of the competition will come in five months when other adalimumab biosimilars, including Boehringer Ingelheim GmbH’s interchangeable, hit the market.
Even though the EU had approved more than a dozen biosimilars by 2012, the follow-on biologics were still in their embryonic stage around the world when BioWorld published The Biosimilars Game: A Scorecard for Opportunities, Threats and Critical Strategies in early 2013. Now, nearly a decade later, the global biosimilar landscape has matured with many more biosimilars approved across the globe, but the uptake, and thus the savings, is not what some policy makers and people in industry had hoped for or expected.
