We report CZP effectiveness and safety in European clinical practice in patients with axSpA, including radiographic (r-) and non-radiographic (nr-) axSpA. CIMAX (NCT02354105), a European non-interventional multicentre prospective study, observed CZP treatment response and safety over 12 months in a real-world axSpA cohort. The primary outcome was change from baseline in BASDAI to week 52, with additional outcomes pertaining to effectiveness and safety. Patients who received ≥1 dose CZP were followed up for adverse events, and those with baseline and ≥1 post-baseline BASDAI assessment were included in effectiveness analyses. A total of 672 patients (r-axSpA: 469; nr-axSpA: 201; unconfirmed diagnosis: 2) from 101 sites received ≥1 dose of CZP, of whom 564 (r-axSpA: 384; nr-axSpA: 179; unconfirmed: 1) were included in the effectiveness analyses. The mean baseline BASDAI was 6.1 in the overall axSpA population and r-axSpA and nr-axSpA subpopulations. At week 52, the mean (s.d.) change in BASDAI was -2.9 (2.3; n = 439); for r-axSpA and nr-axSpA, it was -2.9 (2.2; n = 301) and -2.8 (2.4; n = 137), respectively (P  Improvements observed in signs and symptoms of axSpA following one year of CZP treatment in real-world clinical practice were similar to those from previous randomized clinical trials, with no new safety concerns. %K Axial spondyloarthritis %K Certolizumab pegol %K Non-interventional %~
