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.
Long considered a make-or-break market for novel drugs and biologics and a success story for generics, the U.S. has been more challenging for biosimilars than many experts initially expected. U.S. biosimilar “uptake has been good, but not great,” Steven Lucio, senior principal for pharmacy solutions at Vizient Inc., told BioWorld. That could change next year when at least seven biosimilars referencing Abbvie Inc.’s immunosuppressive drug, Humira (adalimumab), are expected to launch in the U.S.
In an effort to get drug regulators in the various EU member states on the same page, the EMA issued a Sept. 19 statement confirming that all biosimilars approved in the EU are interchangeable with other approved biosimilars referencing the same biologic, as well as the reference biologic itself.
2023 may be a pivotal year for biosimilars in the U.S. with a number of approved Humira (adalimumab) biosimilars set for staggered launches under agreements with Abbvie Inc. How successful those launches are, including the launch of Boehringer Ingelheim GmbH’s interchangeable, Cyltezo, and potential other interchangeables, will be determined in large part by three pharmacy benefit managers that together control the prescription drug formularies for nearly 80% of Americans covered by Medicare and private insurance.
Ushering in a new era for the U.S. biosimilar marketplace, the FDA, on July 28, approved its first interchangeable biosimilar, which also will be the first to bring biosimilar competition to the U.S. insulin space. The honor went to Viatris Inc.’s Semglee, which the FDA recognized as both biosimilar to and interchangeable with Sanofi SA’s blockbuster drug Lantus (insulin glargine), a long-acting insulin analogue.
More than a decade after the Biologics Price Competition and Innovation Act became law and nearly six years after the first biosimilar launched in the U.S., the country’s first potential interchangeable is on deck awaiting an FDA decision.
