The Era of Biosimilars is Here

With some biosimilars on the market and more on the way, we expect – and are prepared for – a meaningful impact on specialty drug trend. With biosimilars, as with all medications, our lowest net cost strategy applies. This means we’ll choose whatever is the lowest net cost option for the plan, which could be a biosimilar or a reference branded product.

Why Biosimilars Matter to Specialty Costs

Increased competition in the drug marketplace is key to making costly drugs more affordable – and we’re taking an active role in ensuring that competition helps solve the challenge of specialty drugs. Whether the biosimilar product or its reference branded product represent the lowest net cost option, our goal is to ensure that the competition provided by biosimilars lowers costs wherever possible.

The Biosimilar State of Play

Since 2015,
32
biosimilars have been approved with
14*
expected in 2022

*14 is a current estimate for 2022, and dependent on FDA responses as well as litigation/settlement outcomes

But of the 32 approved biosimilars, only
21
are currently on the market, covering 10 different drugs

Of the 11 biosimilars that are approved and not yet available, the majority are for Humira and Enbrel and will not be available until 2023 and 2029 respectively.

Maximizing the Potential of Biosimilars

We’re already in proactive discussions on how new biosimilar options coming to market may impact our clients in the future. Once approved, we conduct new-to-market product reviews and ongoing evaluations to stay abreast of this evolving marketplace given its potential, positive impact to drug spend.

As more specialty products lose marketing exclusivity over the next decade, the increase in both biosimilar and generic competition will have a material impact on the cost savings we can achieve for our clients.
