Efficacy and Safety of CT-P13 (Infliximab Biosimilar) over Two Years in Patients with Ankylosing Spondylitis: Comparison Between Continuing with CT-P13 and Switching from Infliximab to CT-P13

Abstract

CT-P13 is an infliximab (INX) biosimilar recently approved by the European Medicine Agency. PLANETAS was a 54-week (wk) randomized double-blind parallel group multicenter Phase I study demonstrating pharmacokinetic equivalence of CT-P13 (5 mg/kg infusion every 8 wks) with INX, in patients (pts) with ankylosing spondylitis (AS) (Park W, ARD 2013;72(S3):516). Here we report results from the extension phase of the Phase I equivalence study, investigating long-term efficacy and safety of extended CT-P13 therapy and switching from INX to CT-P13 in pts with AS.
