Treatment of moderate-to-severe chronic plaque PsO with either CZP 400 mg or 200 mg Q2W was associated with significant, clinically meaningful improvements in efficacy and quality of life that were maintained over time compared with placebo. Safety findings were in line with those expected of the therapy.

In this phase 3 study, both 200mg and 400mg certolizumab pegol doses improved psoriasis symptoms at Week 12 measured via PASI 75. Improvement was maintained, after rerandomisation, through Week 48, with a safety profile consistent with its drug class. This Phase 3 CIMPACT trial by Lebwohl et al., assessed the safety and efficacy of certolizumab pegol for the treatment of moderate-to-severe chronic plaque psoriasis.
