Implementation of CT-P13 via a Managed Switch Programme in Crohn’s Disease: 12-Month Real-World Outcomes

Abstract

Background

Switching from Remicade to CT-P13 allows for significant cost savings and has been shown to be non-inferior to continued therapy with Remicade for the treatment of Crohn's disease.

Aim

The aim of this work was to prospectively evaluate clinical outcomes in a cohort of patients with Crohn's disease switching from Remicade to CT-P13.

Methods

A prospective service evaluation was performed. The Harvey-Bradshaw index, CRP, faecal calprotectin and serum for infliximab/antibody levels were collected prior to patients' final Remicade infusion and at 6 and 12 months after switching to CT-P13 as part of routine clinical care. All adverse events during follow-up were also recorded.

Results

One hundred and ten patients on Remicade switched to CT-P13. No significant difference was observed between the Harvey-Bradshaw Index (p = 0.07), CRP (p = 0.13), faecal calprotectin (p = 0.25) or trough infliximab levels (p = 0.47) comparing before and at 6 and 12 months after the switch to CT-P13. Seven patients developed new infliximab antibodies after switching from Remicade to CT-P13. The majority of patients remained on CT-P13 at 12 months (84.5%) and the rate of adverse events and serious adverse events was 53.8 and 13.5 per 100 patient-years of follow-up, respectively. Switching to CT-P13 resulted in a cost saving of approximately 46.4%.

Conclusion

The transition to CT-P13 from Remicade for the treatment of Crohn's disease is safe and has no negative effect on clinical outcomes at 12 months.
