Description of intervention(s) / exposure
Treatment: Drugs - Semuloparin Sodium
Treatment: Drugs - Enoxaparin sodium
Treatment: Drugs - Placebo

Experimental: Semuloparin - Semuloparin sodium 20 mg (10 mg if Severe Renal Impairment \[SRI\]) once daily for 7-10 days with an initial dose given 8 hours after surgery (placebo for Enoxaparin sodium prior to surgery according to local standard for Enoxaparin and 12 hours after surgery to maintain the blind)

Active comparator: Enoxaparin - Enoxaparin sodium 40 mg (20 mg if Severe Renal Impairment \[SRI\]) once daily for 7-10 days with an initial dose given prior to or 12 hours after surgery according to local standard for Enoxaparin sodium (placebo for Semuloparin sodium 8 hours after surgery to maintain the blind)

Summary
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.
