29 October 2025 - The US FDA today announced significant action to make it faster and less costly to develop biosimilar medicines, which are lower-cost “generic” alternatives to biologic drugs that treat serious and chronic diseases.
In a new draft guidance, the FDA proposes major updates to simplify biosimilarity studies and reduce unnecessary clinical testing. The agency through a separate initiative also plans to make it easier for biosimilars to be developed as interchangeable with brand-name biologics, helping patients and pharmacists choose lower-cost options more easily.
