Golimumab and immunogenicity? 2010 and beyond

Immunogenicity is a frequent adverse event observed with biological agents' therapy. Challenges of management in patients with rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis treated with golimumab, an anti-TNF-alpha blocker, include limited generation of antibodies like anti-nuclear, anti-golimumab, and anti-double stranded DNA antibodies. We conducted here a meta-analysis study in order to evaluate and compare the newly generated antibody levels after golimumab therapy. The examination of original clinical trials revealed that their levels were neither higher nor significant. Moreover, no evident associations between the induced-antibodies and lupus-like syndromes and/or infusion site reaction were reported. The reduced patients cohort and the absence of systematic newly generated antibodies follow-up might be implicated in the difficulty to evaluate their risk in delaying diseases therapy, and/or predicting for their worse prognosis. Hence, further studies are required to ascertain the real impact of the induced antibodies after golimumab's therapy.
