Alexion Pharmaceuticals Provides Update on APEX-AMI Trial

CHESHIRE, Conn., Feb. 3 (HSMN NewsFeed) -- Alexion Pharmaceuticals, Inc. (Nasdaq: ALXN ) announced today that, together with its partner Procter & Gamble Pharmaceuticals, they had determined to finalize the ongoing APEX-AMI pexelizumab trial. It is anticipated that approximately 5,000 patients will have been enrolled in the trial, one of the largest acute myocardial infarction trials performed to date. The trial is expected to complete enrollment near the beginning of March.

"We are very grateful to the hundreds of clinical investigators and thousands of patients around the world who have participated in the APEX-AMI trial and we look forward to reviewing the final data from the trial in the second half of this year," said Leonard Bell, M.D., Chief Executive Officer of Alexion. "We continue to focus our efforts on execution of regulatory and pre-launch activities of our lead product, Soliris, following the successful completion of the TRIUMPH Phase III trial for PNH last month."

About Alexion:

Alexion is engaged in the discovery and development of therapeutic products aimed at treating patients with a wide array of severe disease states, including hematologic and cardiovascular disorders, autoimmune diseases and cancer. Alexion's two lead product candidates, Soliris(TM) (eculizumab) and pexelizumab, are currently undergoing evaluation in several clinical development programs, including two Phase III trials of Soliris(TM) (eculizumab) for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). Under the Special Protocol Assessment (SPA) process, the FDA has agreed to the design of protocols for the two trials of Soliris(TM) (eculizumab) in PNH patients that could, if successful, serve as the primary basis of review for approval of a licensing application for eculizumab in the PNH indication. The Company's Phase III trial of pexelizumab in coronary artery bypass graft (CABG) surgery patients undergoing cardiopulmonary bypass (CPB) failed to achieve its primary endpoint. The Company has determined to finalize its ongoing Phase III trial of pexelizumab in acute myocardial infarction (AMI) patients. The pexelizumab trials are conducted in collaboration with Procter and Gamble Pharmaceuticals. Under the SPA process, the FDA has agreed to the design of protocols for the Phase III pexelizumab trials that could, if successful, serve as the primary basis of review for approval of licensing applications for the two indications. Preliminary results from the PRIMO-CABG2 trial of pexelizumab indicate that the trial is unlikely to support filing for licensing approval of pexelizumab in the CABG indication. Alexion is engaged in discovering and developing a pipeline of additional antibody therapeutics targeting severe unmet medical needs, through its wholly owned subsidiary, Alexion Antibody Technologies, Inc.
