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.”
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.
Although broader use of biosimilars in the U.S. would reduce Medicare Part D spending and save beneficiaries nearly $2 million in out-of-pocket costs, plan formularies continue to discourage the use of the more affordable follow-ons, according to a recent report from the Department of Health and Human Services’ Office of Inspector General.
With the next big wave of biologic patent expirations soon to wash over the U.S. market, companies developing biosimilars are optimistic about the future. “We’re at a place where we’re seeing really strong uptake of biosimilars, which has resulted in cost savings,” Chad Pettit, executive director of marketing for Amgen Inc.’s biosimilars unit, told BioWorld.
The first wave of biosimilars began lapping at U.S. shores five years ago when the FDA approved Sandoz Inc.’s Zarxio on March 6, 2015, giving it a label identical to that of its reference biologic, Amgen Inc.’s Neupogen (filgrastim). But the tsunami of biosimilars, and the multibillion dollars of savings they were expected to bring, has yet to wash ashore.
