Anti-ustekinumab antibodies are anti-drug antibodies (ADAs) that can develop in response to therapeutic administration of ustekinumab, a monoclonal antibody targeting interleukin-12 (IL-12) and interleukin-23 (IL-23). These antibodies may be generated by the patient’s immune system as a defense mechanism against the biologic drug, particularly when repeated or long-term treatment is involved. The presence of anti-ustekinumab antibodies may impact the drug’s pharmacokinetics, efficacy, and safety, potentially diminishing the therapeutic response in chronic inflammatory conditions such as psoriasis and inflammatory bowel diseases.
In both research and clinical settings, monitoring anti-ustekinumab antibodies is essential for understanding immune tolerance and assessing treatment durability. The development of neutralizing antibodies may hinder ustekinumab’s ability to bind to IL-12/23p40, blocking its immunosuppressive function and contributing to therapeutic resistance. Assays designed to detect and quantify these antibodies help clinicians make informed decisions about dose adjustments or switching therapies.
Therapeutic drug monitoring (TDM) of ustekinumab and its corresponding antibodies can improve individualized treatment by evaluating patient compliance, drug efficacy, and immunogenicity. In clinical trials and post-marketing surveillance, measuring anti-ustekinumab levels provides valuable insights into adverse immune responses, aiding in the optimization of biologic therapies and enhancing patient outcomes in autoimmune disease management.
