Abstract
Background The NOR-SWITCH main and extension trials demonstrated that switching from originator to biosimilar infliximab (CT-P13) is efficacious and safe across six diseases. However, a subgroup analysis of Crohn’s disease (CD) in the main trial displayed a close to significant difference favouring originator infliximab, and more scientific data have therefore been requested.
Objective The aim was to assess treatment efficacy, safety, and immunogenicity in an explorative subgroup analysis in CD and ulcerative colitis (UC) in the NOR-SWITCH trials. Patients and Methods The 52-week, randomised, non-inferiority, double-blind, multicentre, phase 4 NOR-SWITCH study was followed by a 26-week open extension trial where all patients received treatment with CT-P13. Treatment efficacy, safety, and immunogenicity in CD and UC were assessed throughout the 78-week study period. Results The main and extension trials included 155 and 93 patients with CD and 93 and 80 patients with UC, respectively. Demographic and baseline characteristics were comparable in both treatment arms within patient groups. There were no differences in the main and extension trials regarding changes in activity indices, C-reactive protein, faecal calprotectin, patient’s and physician’s global assessment of disease activity and patient-reported outcome measures in CD and UC. Moreover, comparable results were also demonstrated for trough serum levels, presence of anti-drug antibodies, and reported adverse events. Conclusion Efficacy, safety, and immunogenicity of both the originator and biosimilar infliximab were comparable in CD and UC in the NOR-SWITCH main and extension trials. These explorative subgroup analyses confirm that there are no significant concerns related to switching from originator infliximab to CT-P13 in CD and UC.

Abstract
BACKGROUND AND OBJECTIVES The 52-week, randomized, double-blind, noninferiority, government-funded NOR-SWITCH trial demonstrated that switching from infliximab originator to less expensive biosimilar CT-P13 was not inferior to continued treatment with infliximab originator. The NOR-SWITCH extension trial aimed to assess efficacy, safety and immunogenicity in patients on CT-P13 throughout the 78-week study period (maintenance group) versus patients switched to CT-P13 at week 52 (switch group). The primary outcome was disease worsening during follow-up based on disease-specific composite measures. METHODS Patients were recruited from 24 Norwegian hospitals, 380 of 438 patients who completed the main study: 197 in the maintenance group and 183 in the switch group. In the full analysis set, 127 (33%) had Crohn's disease, 80 (21%) ulcerative colitis, 67 (18%) spondyloarthritis, 55 (15%) rheumatoid arthritis, 20 (5%) psoriatic arthritis and 31 (8%) chronic plaque psoriasis. RESULTS Baseline characteristics were similar in the two groups at the time of switching (week 52). Disease worsening occurred in 32 (16.8%) patients in the maintenance group vs. 20 (11.6%) in the switch group (per-protocol set). Adjusted risk difference was 5.9% (95% CI -1.1 to 12.9). Frequency of adverse events, anti-drug antibodies, changes in generic disease variables and disease-specific composite measures were comparable between arms. The study was inadequately powered to detect noninferiority within individual diseases. CONCLUSION The NOR-SWITCH extension showed no difference in safety and efficacy between patients who maintained CT-P13 and patients who switched from originator infliximab to CT-P13, supporting that switching from originator infliximab to CT-P13 is safe and efficacious.
