Important update regarding anti-thymocyte globulin (Thymoglobuline®)

Genzyme informs healthcare professionals of the potential presence of trace amount of 2,4-dichlorobenzoic acid (2,4-DCBA) in some vials of Thymoglobuline® injection filled at the Waterford, Ireland facility. Investigations and root cause analysis identified the source to be a leachable from the peroxide-cured silicone tubing used at the Waterford filling line. Through investigations and safety database review, Genzyme concluded that the likelihood of 2,4-DCBA being present in Thymoglobuline® is extremely low and risk to patient safety is low. As part of Genzyme's corrective action plan, the peroxide-cured tubing was replaced with new tubing that does not contain 2,4-DCBA on 25 Feb 2010. Affected batches of Thymoglobuline® available locally will be replaced with product manufactured using the new tubing by mid Jun 2010.
