Efficacy variables in patients following dose reduction from certolizumab pegol (CZP) 400 mg every 2 weeks (Q2W) to CZP 200 mg Q2W (n = 369). a Mean disease activity score in 8 joints (erythrocyte sedimentation rate) (DAS28(ESR)). bAmerican College of Rheumatology (ACR)20 response rates. c ACR50 and ACR70 response rates. This analysis is presented as weeks following dose-reduction visit (Week 0 is defined as the final efficacy assessment visit where a patient received the CZP 400 mg dose). The sharp decline in patient numbers from week 150 following dose reduction is due to the per-protocol site closures in countries where CZP became commercially available.
