Background: Certolizumab pegol (CZP) is Food and Drug Administration (FDA)-approved to treat Crohn's disease (CD). However, the efficacy and safety of CZP outside clinical trials are not well established. Aim: To report the efficacy, safety and predictors of response to CZP in CD patients treated during a 6-year period since FDA-approval at a tertiary care centre. Methods: All CD patients who received CZP at our institution between 2008 and 2013 were evaluated through retrospective medical record-based review of steroid-free complete response (SCR), loss of response and safety. Results: A total of 358 patients were included. One hundred twelve patients (31.3%) and 189 (52.8%) received CZP as their second and third biological agent, respectively. The probability of SCR at 26 week was 19.9% (95% CI, 15.9–24.5). The probability of survival free of loss of response at 2 year was 45.7% (95% CI, 32.5–59.5). A predictor of SCR was age at CD diagnosis of >40 years old (hazard ratio, HR relative to those <17, 4.69; 95% CI, 1.75–12.61). Negative predictors included present perianal fistula (HR, 0.39; 95% CI, 0.16–0.98) and prior primary nonresponse to adalimumab (ADA; HR relative to secondary loss of response, 0.18; 95% CI, 0.04–0.76). Twenty-three patients (6.4%) experienced serious adverse events and 19 patients (5.3%) discontinued CZP due to adverse events. Conclusions: Certolizumab pegol was both effective and well tolerated for the treatment of Crohn's disease in this large tertiary care centre enriched with biologics-exposed patients. It may be more effective in patients without early-aged Crohn's disease diagnosis, prior primary nonresponse to adalimumab and present perianal fistula.
