Commercial Insurance Restrictions Complicate Biosimilar Adoption

Since the FDA’s approval of the first biosimilar in 2015, the agency has approved almost 40 more agents. However, their adoption in the U.S. market has been slow. A recent study, published in the journal BioDrugs, found that biosimilars were covered more restrictively than their reference biologics in 19.4% of coverage decisions made by select commercial health plans.

The study examined 1,181 coverage decisions made by 17 commercial health plans as of August 2021 from the Tufts Medical Center Specialty Drug Evidence and Coverage database, which included 19 commercially available biosimilars for seven biologic reference products used in treating 28 conditions.
