What is the Meaning of Immunogenicity Risk?

Immunogenicity Risk refers to the inherent potential for a therapeutic agent, particularly large biological molecules like therapeutic proteins or peptides used in hormone replacement, to elicit an unwanted immune response in the recipient. In endocrinology, this is paramount when administering exogenous hormones or growth factors, as antibody formation can neutralize the intended therapeutic effect or cause adverse reactions. We must clinically assess this risk when considering non-oral delivery systems.

What is the Origin of Immunogenicity Risk?

This term derives from immunology, where "immuno-" pertains to the immune system and "-genicity" denotes the capacity to induce an immune response. Its application in hormone therapy became more prominent with the advent of recombinant hormone production and the use of complex delivery vehicles. The risk profile is dictated by the molecular structure's similarity to endogenous proteins.

What is the Mechanism of Immunogenicity Risk?

The mechanism involves the recognition of the therapeutic molecule as foreign by antigen-presenting cells, leading to T-cell activation and subsequent B-cell production of neutralizing antibodies. These antibodies can bind to the administered hormone, reducing its free circulating concentration and effectiveness, thereby leading to treatment failure. Alternatively, immune complexes can form, potentially causing hypersensitivity reactions or vasculitis. Controlling the route of administration and the purity of the preparation are key strategies to modulate this inherent biological risk.
