Pre-filled small volume syringe for intravitreal injection to treat e.g. ocular disease, has plunger including contact surface to contact stopper, and backstop with projections, where syringe is filled with growth factor antagonist fluid

摘要

The syringe (1) has a stopper arranged within a body (2) such that a front surface of the stopper and the body define a variable volume chamber from which a fluid is expelled though an outlet of the body, and a backstop (6) including two finger projections. A plunger (4) comprises a plunger contact surface to contact the stopper such that the plunger forces the stopper towards an outlet end. The syringe is filled with a vascular endothelial growth factor (VEGF) antagonist fluid of about 0.15-0.175 ml containing a non-antibody VEGF antagonist aflibercept at a concentration of 40 mg/ml. The syringe comprises a syringe barrel filled with silicone oil of 100 microgram.
