H.6.Investigation: one injector attached to a syringe, protector and vial, along with two additional protectors attached to a vial were returned to our quality team for investigation.The product was visually inspected, no defects or damage was observed on the protectors, the protectors fit securely to the vial, and the needle on the protector penetrated the vial stopper properly.Through visual inspection, a foreign particle was observed inside the syringe.Characterization testing was performed and identified the particle was likely fragments of the rubber stopper from the vial.Fragmentation testing is performed during manufacturing to identify any particles generated by the injector after ten activations.A device history review was performed for reported lot 1901129, no deviations or non-conformances were identified during the manufacturing process that could have contributed to this issue.While phaseal needles are designed to reduce coring, there are several factors that may impact coring tendency.Coring of the rubber stopper may result depending on the stopper quality, the design and dimensions of the needles used, or if a poor connection of the protector occurs.It is important to ensure the vial is not expired as that can impact the quality of the rubber stopper.Based on the available information we are not able to identify a definitive root cause at this time.
