To streamline the development of biosimilars and align it with current analytical science, regulators across the globe are reevaluating a routine requirement for comparative clinical efficacy studies for biosimilar candidates.
Forget location. It’s timing, timing, timing when it comes to escaping the first round of U.S. Medicare price negotiations due to pending biosimilar competition. Under the Inflation Reduction Act (IRA), only single-source drugs that have been approved for a specific length of time are subject to the forced negotiations, which focus on drugs with the biggest Medicare spend, not necessarily the highest price tag. Since the IRA gives biologics a 12-year safe harbor from negotiations, which aligns with the biologic exclusivity provided by the Biologic Price Competition and Innovation Act, it creates a scenario in which the innovator could be facing negotiations just as its first biosimilar competition prepares to launch. That creates a lot of what-ifs.
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.
Nearly 13 years after Congress created a biosimilars path to bring competition to the U.S. biologics market, new rules of the road are coming into play, via the Inflation Reduction Act (IRA), that could change the course for biosimilars in the long haul – if the IRA’s prescription drug price negotiation mandate withstands numerous constitutional challenges.
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 slew of biosimilar versions of TNF-alpha inhibitor adalimumab will finally arrive on the U.S. market in 2023, almost seven years after the first such molecule, Amgen Inc.’s Amjevita (adalimumab-atto) gained U.S. FDA approval. Amgen commercially launched its product on Jan. 31. Seven more are lined up for launch over the summer, while two more are undergoing regulatory review. Their long-anticipated arrival will mark the beginning of the end for one of the most lucrative franchises in the history of the pharmaceutical industry. It represents, according to Cardinal Health Inc.’s newly published 2023 Biosimilars Report, “the largest loss of exclusivity event, perhaps ever in the U.S.”
If the Feb. 16 hearing before the U.S. Senate Commerce Committee is anything to go by, it’s almost a given that the bipartisan Pharmacy Benefit Manager (PBM) Transparency Act will eventually be passed by the Senate. But its journey through the Republican-controlled House could be more uncertain in light of growing concerns about an “activist agenda” at the FTC.
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.
With at least six others behind it, Amgen Inc.’s Amjevita is leading a 2023 U.S. biosimilars charge to challenge the all-time biggest-selling drug, Humira (adalimumab), from Abbvie Inc. Amjevita hit the U.S. market Jan. 31, and Amgen has the biosimilar priced at two levels, both lower than Humira’s. One is a list price 55% below Humira’s list price of about $115,000 annually and the second is 5% below Humira’s list price. Boehringer Ingelheim GmbH, Sandoz Inc., Samsung Bioepis Co. Ltd./Organon & Co., Pfizer Inc., Viatris Inc. and Coherus Biosciences Inc. all have biosimilar challengers to Humira that are set to launch in July 2023, all likely to come with a lower price tag than Humira’s.
