Drug preparation is performed on the day of administration, but is time consuming, causing unnecessary in-hospital patient delay and inefficient logistics for preparation and distribution.

The aim of this study was to test the shelf life and stability of ready-to-administer intravenous infusion bags containing vedolizumab.</p><p><strong>Methods: </strong>For assessing in-use shelf life, the reconstituted product (300 mg fixed dose) was diluted to a concentration of 1.2 mg/mL in 0.9% NaCl under aseptic conditions, and stored in polyolefin infusion bags at 2-8°C prior to analysis. On replicate samples, we measured concentration, physical and chemical stability using sodium dodecyl sulphate polyacrylamide gel electrophoresis, size exclusion chromatography, and multi-angle laser light scattering, as well as biological activity using a biolayer interferometry assay to study target engagement, and endotoxin content to assess microbiological stability. Stability of ready-to-use vedolizumab was assessed also after transportation via pneumatic tube system.
