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.

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.
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.
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).
Manufacturing deficiencies stand in the way of two BLAs as complete response letters (CRLs) were issued to Eli Lilly and Co. and to Alvotech Holdings SA. The U.S. FDA issued the CRL to Lilly regarding the BLA for mirikizumab, a humanized IgG4 monoclonal antibody to treat ulcerative colitis, specifically citing manufacturing concerns. There’s a similar problem with Alvotech’s biosimilar candidate for Abbvie Inc.’s Humira (adalimumab). The FDA issued a CRL for AVT-02’s BLA, citing problems needing resolution at its Reykjavik, Iceland, manufacturing facility before it could approve the application.
