One of the greatest theoretical clinical concerns regarding the development of biosimilars has been that post-translational protein modifications, even while antigen binding remains essentially unaltered, might result in detrimental immunogenicity. We recently published an article in BioDrugs [1] that demonstrated that the Summary of Product Characteristics (SmPCs) of biological drugs, approved by the European Medicines Agency (EMA), are very heterogeneous regarding the issues related to immunogenicity that are addressed within these documents. A complementary analysis, using the methodology advanced in our article [1], to the EMA’s “Procedural Steps Taken and Scientific Information After the Authorisation” documents shows that 57% (39/69) of the biological drugs that have been authorized prior to 2012 did not update their SmPC at least once when it comes to information related to unwanted immunogenicity. These are surprising results given the advancements that have been seen in the...
