A positive outlook for the US biosimilars market

The US is keeping pace with the European pioneers of biosimilars approvals, reveals an article published in GaBI Journal [1].

The authors of the article [1] highlight that although the European Medicines Agency (EMA) pioneered the framework for biosimilar regulation, the US Food and Drug Administration (FDA) is moving at a similar pace. In September 2020, 10 years after implementation of the biosimilar approval pathway, 28 biosimilars had been approved by FDA. In Europe, 13 were approved in the first 10 years.

Interchangeability
Although the US and the EU’s biosimilars trajectory is similar, a point of divergence between the terrain in the two regions is the concept of interchangeability [2]. In the US, FDA can designate a product ‘interchangeable’ if it meets additional requirements beyond being biosimilar, which include to more clinical development and switching studies. However, the article notes that at the time it was published, no biosimilar products had achieved interchangeability status. In addition, interchangeable biosimilars are thought to give the false impression that they are superior to those without this status. As such, it is highlighted that physicians and payers need education regarding interchangeability to prevent confusion over biosimilars with or without the interchangeability status.

Overall, perceptions of prescribing physicians about the safety of biosimilars and switching to biosimilars, remains an ongoing issue. However, it is thought that the increased evidence now available regarding the safety of switching to biosimilars will improve prescriber and patient confidence in them.

The biosimilars marketplace
In Europe, the biosimilars marketplace varies significantly in different Member States. An average of hospital biosimilar volumes recorded in March 2019 showed that Denmark had the highest uptake by volume, with 63% overall, whereas Belgium and Switzerland had just 14%.

In the US, biosimilars have gained significant share in the majority of therapeutic areas in which they have been introduced. The authors also note that in combination, biosimilar competition and originator manufacturer responses to reduce prices, led to annualized savings US$6.5 billion in the second quarter of 2020.

Overcoming biosimilar barriers in the US
Although 28 biosimilars have been approved in the US, only 18 are available. Delays in commercialization are due to anti-competitive behaviours and patent-related barriers created by manufacturers of branded originator drugs.

FDA has taken steps to mitigate barriers to biosimilar utilization, including enacting the Biosimilars Action Plan (BAP) to advance policies that facilitate the development of the biosimilars market and increase competition for biological drugs. In addition, FDA and the Federal Trade Commission (FTC) have identified goals to help combat anti-competitive practices. FDA has released a ‘Draft guidance for industry: promotional labelling and advertising considerations for prescription biological reference and biosimilar products ‒ questions and answers’, to aid successful market entry.

In February 2020, FDA also issued draft guidance to speed its review of biosimilar or interchangeable application supplements. Such supplements will now be reviewed and acted upon within six months.

In addition, the US Centers for Medicare and Medicaid Services (CMS) have also revised a number of their payment policies to promote biosimilar competition.

Overall, the authors state that overall outlook for biosimilars in the US is positive. Many have been approved and the barriers to market entry are being addressed. In addition, biosimilars are helping to bring down the cost of drugs in the US market and are positioned to achieve further savings.
