Abstract
BACKGROUND AND AIM: A biosimilar of infliximab, CT-P13 (Remsima®) has the potential to reduce treatment costs and enhance access to biological therapy for inflammatory bowel disease (IBD) patients. However, long-term clinical data on its use for IBD treatment are currently sparse. We aimed to investigate the long-term efficacy and safety of CT-P13 therapy in a large, real-life IBD cohort.
METHODS: A total of 368 IBD patients (227 with Crohn’s disease [CD] and 141 with ulcerative colitis [UC]) treated with CT-P13 at 16 referral hospitals in Korea between July 2012 and December 2017 were retrospectively analyzed.
RESULTS: The cumulative retention rates at year 1, 3, and 5 were 86.1%, 68.5%, and 58.7% and 69.7%, 46.0%, and 26.7% in anti-tumor necrosis factor (TNF)-naïve CD and UC patients, respectively. The clinical response and remission rates at week 14 and at year 1, 3, and 5 were 94.3%, 92.7%, 76.8%, and 17.6% and 78.6%, 82.4%, 72.2%, and 17.6% in anti-TNF-naïve CD and 85.6%, 80.0%, 55.2%, and 6.7% and 42.6%, 59.8%, 44.2%, and 6.7% in anti-TNF-naïve UC patients, respectively. Among patients who switched from the biologic originator to CT-P13, the cumulative retention rates at year 1, 3, and 5 were 88.5%, 66.1%, and 44.8% in CD, and 73.9%, 42.5%, and 42.5% in UC patients, respectively. Significant improvements in disease activity scores were accompanied by marked reductions in inflammatory marker levels, and no unexpected adverse events including death or malignancy occurred during the study period.
CONCLUSIONS: Long-term treatment with CT-P13 is effective in inducing and maintaining disease improvement, and is well-tolerated in patients with IBD. CT-P13 may be a promising treatment option for IBD.
