Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Semuloparin sodium
Treatment: Drugs - Enoxaparin
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

To maintain the blind, placebo for Enoxaparin sodium:

* 12 and 24 hours after surgery, then once daily if no SRI
* 12 hours after surgery only if SRI

Active comparator: Enoxaparin - Enoxaparin sodium 30 mg twice daily (20 mg once daily if Severe Renal Impairment \[SRI\]) for 7-10 days with an initial dose given 12 hours after surgery

Placebo for Semuloparin sodium 8 hours after surgery to maintain the blind


Treatment: Drugs: Semuloparin sodium
0.3 mL (0.2 mL if SRI) solution in ready-to-use 0.5 mL pre-filled syringe

Subcutaneous injection

Treatment: Drugs: Enoxaparin
0.3 mL (0.2 mL if SRI) solution in ready-to-use 0.5 mL pre-filled syringe

Subcutaneous injection

Treatment: Drugs: Placebo
0.3 mL (0.2 mL if SRI) solution in ready-to-use 0.5 ml prefilled syringe strictly identical in appearance but without active component
