Sammanfattning

BACKGROUND AND AIMS: Vedolizumab is a gut-selective treatment approved for Crohn's disease (CD) and ulcerative colitis (UC). Recently, a subcutaneous formulation of vedolizumab was approved. The aims of this study were to evaluate efficacy, safety, pharmacokinetics, patient experience and costs following a switch from intravenous to subcutaneous vedolizumab treatment.

METHODS: Patients were switched from intravenous to subcutaneous vedolizumab maintenance treatment and followed prospectively for 6 months and a subgroup for 12 months. The primary endpoint was change in faecal calprotectin levels. Furthermore, we evaluated clinical disease activity, remission rates, plasma CRP, drug persistence, adverse events, local injection reactions, serum drug concentrations, patient satisfaction, quality-of-life and treatment costs.

RESULTS: Eighty-nine patients were included (48 CD; 41 UC). Faecal calprotectin decreased significantly in CD but not in UC. Clinical indices, remission rates, plasma CRP levels and quality-of-life scores remained unchanged. Patients that had been on standard compared to optimised IV vedolizumab dosing displayed similar outcomes on standard SC dosing. Drug persistence at 6 and 12 months was 95.5% and 88.5%, respectively. Frequencies of adverse events were similar before and after the switch. No serious adverse events occurred. Transient severe local injection reactions were experienced by 1.2% of patients. Median vedolizumab trough levels were 2.3 times higher on subcutaneous compared to intravenous treatment. Patient satisfaction was generally high. Annualised treatment costs were reduced by 15% following the switch.

CONCLUSIONS: The switch from intravenous to subcutaneous vedolizumab could be done with preserved therapeutic effectiveness, safety, high patient satisfaction and low discontinuation rate, at a reduced cost.
