True biosimilars do not offer a compelling business case The differences between biosimilars, biosuperiors and next-generation innovative drugs are not clearly defined. However, there is a consensus that biosimilars must replicate as closely as possible the innovator biologic. Since changes to biologics may result in unpredictable consequences, by definition, the biosimilar must be as good or as bad as the innovator drug in all respects. example, a biosuperior performance of cannot improve too the innovator. much upon the original On the other biologic or it becomes hand, biosuperiors a next-generation introduce more innovative drug, which clinical risk because has greater rewards new features have but also greater risks. been introduced into If the changes result the molecule.

Biosuperiors have many of the benefits of biosimilars, but have a dramatically lower development risk compared with truly novel biologics. Since examples of all three classes of biologics are moving through clinical development now, these questions should all be answered with real-world data over the next few years. PTE “...the risks... more than negate the single advantage (cost) provided by [biosimilars]” Developers aiming to create a biosuperior can improve on the original to generate clinical and market advantages, but there is still a line that must not be crossed; for Based on a contribution by David E.
