The Food and Drug Administration (FDA) has issued new draft guidance that does not require additional switching studies for biosimilars seeking interchangeability. These studies were previously recommended to demonstrate that switching between the biosimilar and its reference product showed no greater risk than using the reference product alone.
“The recommendations in today’s draft guidance, when finalized, will provide clarity and transparency about the FDA’s thinking and align the review and approval process with existing and emerging science,” said Sarah Yim, MD, director of the FDA’s Office of Therapeutic Biologics and Biosimilars in a statement on June 20. “We have gained valuable experience reviewing both biosimilar and interchangeable biosimilar medications over the past 10 years. Both biosimilars and interchangeable biosimilars meet the same high standard of biosimilarity for FDA approval and both are as safe and effective as the reference product.”
An interchangeable status allows a biosimilar product to be swapped with the reference product without involvement from the prescribing provider, depending on state law.
While switching studies were not required under previous FDA guidance, the 2019 document did state that the agency “expects that applications generally will include data from a switching study or studies in one or more appropriate conditions of use.”
However, of the 13 biosimilars that received interchangeability status, 9 did not include switching study data.
“Experience has shown that, for the products approved as biosimilars to date, the risk in terms of safety or diminished efficacy is insignificant following single or multiple switches between a reference product and a biosimilar product,” the FDA stated. The agency’s investigators also conducted a systematic review of switching studies, which found no differences in risk for death, serious adverse events, and treatment discontinuations in participants switched between biosimilars and reference products and those that remained on reference products.
“Additionally, today’s analytical tools can accurately evaluate the structure and effects [of] biologic products, both in the lab (in vitro) and in living organisms (in vivo) with more precision and sensitivity than switching studies,” the agency noted.
The FDA is now calling for commentary on these draft recommendations to be submitted by Aug. 20, 2024.
