Safety of Long-term Treatment With Certolizumab Pegol in Patients With Crohn's Disease, Based on a Pooled Analysis of Data From Clinical Trials
Clinical Gastroenterology and Hepatology(2016)
摘要
Background u0026 Aims Treatments for Crohnu0027s disease (CD) have been linked to serious infections, malignancies, and dermatologic complications. We pooled and analyzed clinical trials of certolizumab pegol, a pegylated humanized Fabu0027 fragment against tumor necrosis factor, to quantify safety events in patients with CD. Methods We collected data from 5 placebo-controlled trials, 9 open-label studies, and 1 dose-regimen study, conducted globally through April 2014. A total of 2570 patients with moderate to severe CD were treated with certolizumab pegol, with 4378.1 patient-years of exposure. Data were analyzed in 2 groups: patients from placebo-controlled (PC) trials treated with placebo (n = 875) or certolizumab pegol (n = 919) for 6 to 38 weeks (the PC group) or all patients exposed to certolizumab pegol (n = 2570), for durations of 6 to 362 weeks (the all-studies group). Incidence rates (IRs; incidence/100 patient-years) of adverse events (AEs) were calculated from first dose through 70 days (approximately 5 half-lives) after the last dose. Results In the PC group, IRs for serious AEs were similar among patients given certolizumab pegol (31.35/100 patient-years) vs placebo (24.33/100 patient-years). IRs of serious infections or malignancies were low among patients receiving short-term treatment with certolizumab pegol (8.49/100 patient-years and 1.01/100 patient-years, respectively, in the PC group) and did not increase with long-term treatment (6.47/100 patient-years and 0.80/100 patient-years, respectively, in the all-studies group). IRs of psoriasis or psoriasiform dermatitis were low in the PC group (1.01/100 patient-years and 0/100 patient-years, respectively); in the placebo group, these IRs were 0.38 per 100 patient-years and 0 per 100 patient-years, respectively. IRs of psoriasis or psoriasiform dermatitis did not increase with long-term treatment (0.93/100 patient-years and 0.09/100 patient-years, respectively, in the all-studies group). Conclusions Based on an analysis of data pooled from 15 trials of patients with CD, the safety profile for long-term therapy with certolizumab pegol therapy is similar to that reported from short-term studies. Overall rates of AEs, serious infections, malignancies, and psoriasis did not increase with long-term treatment, suggesting a favorable risk–benefit ratio with long-term certolizumab pegol therapy in CD.
