Alexion Provides Update on Recall of Two Soliris Lots; Says No Effect on FY14 Outlook

Alexion Pharmaceuticals

today is providing further information regarding a previously communicated voluntary recall of two lots of Soliris® (eculizumab) Concentrated Solution for Intravenous Infusion. As stated on Nov. 12, 2013, the two lots were found to contain visible particles. At that time, Alexion provided instructions to return any unused vials of Soliris from these two lots at the distributor level. Alexion is now providing the same instructions at the hospital/user level. The administration of particulate, if present in a parenteral drug, poses a potential safety risk to patients in two general areas: immunogenicity and thromboembolic events. Particulates could cause blockage of flow of blood in vessels, which could be life-threatening. To date, there have been no product complaints of particulates, or identifiable safety concerns attributed to the product consumed from the affected lots. As previously stated, Alexion does not anticipate any interruption to patient supply of Soliris. The product is approved as a treatment for patients with paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome, two ultra-rare disorders. Alexion and its distributors typically ship Soliris to healthcare providers in small quantities, which are timed to individual patient infusions, with the product being consumed before more is shipped. As product was last shipped on Nov. 1, 2013, Alexion believes there is little, if any, inventory currently being held at the hospital or user level. The following table lists the two affected lots, which were distributed nationwide. Expiration First Last Product     Lot     Date     Ship Date     Ship Date Soliris® (eculizumab) Oct. 11, Nov. 1, 300 mg/30 mL     10010A     Oct. 31, 2015     2013     2013 Concentrated solution for intravenous infusion only     10001-1     July 31, 2014     June 4,     May 8, 2012 2013 NDC 25682-001-01 As previously disclosed, Alexion believes that it has identified the filling process step that resulted in the presence of the visible particles and implemented the change necessary to correct the issue. To date, visible particles have not been observed in other lots of Soliris distributed in the U.S. Any person in possession of vials of Soliris from these lots should stop use and arrange for return of the product to Alexion immediately by calling 1-888-SOLIRIS (888-765-4747). Alexion will replace any recalled vials of Soliris. Unaffected lot numbers can continue to be used according to the instructions for use.
