Certolizumab pegol is a recombinant, humanized F(ab)’ fragment of an antibody conjugated to polyethylene glycol to enhance its plasma half-life. It does not contain an FC region and therefore does not cause antibody-dependent cell-mediated or complement-dependent cytotoxicity as described for infliximab, etanercept, and adalimumab. Another difference is that certolizumab pegol preferentially penetrates inflamed tissue compared to noninflamed tissue, and does so to a greater extent than adalimumab or infliximab. It is directed against soluble and membrane-associated human TNF-α and was approved for the treatment of Crohn’s disease that does not respond to conventional therapy in 2008 and for RA in 2009.
