Certolizumab pegol (Cimzia®) is a PEGylated, Fab'-only, recombinant humanized antibody against TNF-α. Subcutaneous certolizumab pegol is indicated for the treatment of various immune-mediated inflammatory diseases (IMIDs), including moderate to severe plaque psoriasis. In pivotal phase III trials in adults with moderate to severe plaque psoriasis, significantly more patients receiving certolizumab pegol 200 mg or 400 mg once every 2 weeks than placebo recipients achieved a ≥ 75% reduction in PASI score (PASI75 responder) and a PGA score of clear/mostly clear with a ≥ 2 point improvement from baseline (PGA0/1 responder) at week 12 (CIMPACT) or 16 (CIMPASI-1 and -2). In CIMPACT, certolizumab pegol 400 mg once every 2 weeks was superior to etanercept (highest recommended dosage) at 12 weeks, with certolizumab pegol 200 mg once every 2 weeks demonstrating non-inferiority, but not superiority, to etanercept. The clinical benefits of certolizumab pegol were maintained during the maintenance phase (to week 48) and the open-label extension phase of these trials. Certolizumab pegol is unique among the biologics, with the absence of an Fc fragment conferring pharmacokinetic advantages; most notably, its minimal transfer across the placenta or into breast milk. Certolizumab pegol was generally well tolerated and no new safety signals were identified in these phase III trials, which complements its established safety profile in other IMIDs. Certolizumab pegol is a useful option for the treatment of moderate to severe plaque psoriasis and provides an important treatment option for pregnant or breastfeeding patients, for whom there are limited options available.© Springer Nature Switzerland AG 2020
