Purpose:Repackaged bevacizumab in single-dose, prefilled syringes for intravitreal injection is available, but with shelf life limited from 60 days to 90 days. For the Study of COmparative Treatments for REtinal Vein Occlusion 2 (SCORE2), 2-mL sterile glass vials were used rather than prefilled syringes to provide a longer shelf life for study supplies.Methods:Repackaged bevacizumab in glass vials was tested at release and, for 1 lot, after 1, 3, 6, and 12 months for physical stability, including concentration, purity and appearance, and for sterility and endotoxins. Vials from 2 lots were tested at release and after 20 months and 21 months, respectively. One lot was tested at 21 months for anti-VEGF bioactivity compared with a fresh supply of commercial bevacizumab.Results:Repackaged bevacizumab in 2-mL glass vials continued to meet all quality release specifications and remain sterile for up to 21 months. In addition, no degradation in anti-VEGF bioactivity was observed at 21 months compared with a fresh bevacizumab control.Conclusion:Bevacizumab can be repackaged into small, single-dose glass vials for intravitreal injection and the qualities of the commercial product maintained, including anti-VEGF bioactivity, for up to 21 months in refrigerated storage. Consideration should be given to repackaging bevacizumab for ophthalmic use in small glass vials as opposed to plastic syringes.
