Biosimilar Development
Could biosimilars be a reliable option for your institution?

Based on a foundation of science
Before a manufacturer applies for FDA approval of a proposed biosimilar, the biosimilar product must go through a rigorous development and testing process.1 This is done via a stepwise approach:

Detailed Analytical Studies1
To identify and compare structural and functional characteristics and to demonstrate the “highly similar” characteristics of a biosimilar product to the reference biologic



Comparative Clinical Studies (if necessary)1
To confirm biosimilarity of the product in patients in at least one approved indication of the reference biologic

A biosimilar must show that it has no clinically meaningful differences in safety, purity, and potency compared with the reference biologic.1
More biosimilars are being developed every year
Biosimilar Product Development Programs Registered With the FDA (by fiscal year)2,3,a
a As of September 2020.


For biosimilars to fulfill their potential to reduce the cost of biologic medicines, it will take the collective efforts of individual institutions and pharmacy directors leading the way through the adoption of biosimilars into their formularies.4
