- Abstract
Objectives: The aim of this post-marketing surveillance (PMS) study is to evaluate the real-world safety and efficacy of CT-P13, the first biosimilar of infliximab (IFX). Methods: Japanese patients with rheumatoid arthritis were prospectively registered from November 2014 and followed up for 1 year. Results: Of 794 patients in the analysis set, 318 patients naïve to biological disease-modifying antirheumatic drugs (bDMARDs) showed an immediate decrease in Disease Activity Score in 28 joints with C-reactive protein (DAS28-CRP) and increased remission rate (DAS28-CRP < 2.6). In patients who switched from IFX to CT-P13 for non-medical reasons (n=374), the low DAS28-CRP due to previous IFX treatment decreased further with continued CT-P13 therapy. As in naïve patients, patients who switched from other bDMARDs, mainly for medical reasons (n=102), responded similarly to CT-P13. CT-P13 in this PMS and IFX in a previous PMS had similar adverse reaction profiles, although the incidence rate in naïve patients in this current PMS was lower due to earlier initiation of CT-P13 therapy. Conclusions: CT-P13 showed excellent effectiveness as first-line therapy, no clinical difficulties in switching from IFX, and clinical improvement in patients who failed other bDMARDs. CT-P13 could be a cost-effective alternative to IFX in the treatment of rheumatoid arthritis.
