Title: A Multinational, Multicenter, Randomized, Double Blind Study Comparing the Efficacy and Safety of AVE5026 With Enoxaparin for the Prevention of Venous Thromboembolism in Patients Undergoing Major Abdominal Surgery
Brief Summary: The primary objective is to compare the efficacy and safety of once daily (q.d.) subcutaneous (s.c.) injections of Semuloparin sodium (AVE5026) with q.d. s.c. injections of Enoxaparin for the prevention of Venous Thromboembolic Events (VTE) in patients undergoing major abdominal surgery.

The secondary objectives are to evaluate the safety of Semuloparin sodium (AVE5026) and to document Semuloparin sodium (AVE5026) exposure in this population.
