Brief Summary

The primary objective was to compare the efficacy of Semuloparin sodium (AVE5026) with Enoxaparin for the prevention of Venous Thromboembolic Events \[VTE\] in patients undergoing elective knee replacement surgery. The secondary objectives were to evaluate the safety of AVE5026 in patients undergoing elective knee replacement surgery, and to document AVE5026 exposure in this population.

Outcome Measures

Primary Outcomes (1)

Percentage of Participants Who Experienced Venous Thromboembolism Event (VTE) or All-cause Death
VTE included any proximal or distal Deep Vein Thrombosis \[DVT\] (symptomatic or not) and non-fatal Pulmonary Embolism \[PE\] as confirmed by a Central Independent Adjudication Committee \[CIAC\] after central and blind review of mandatory bilateral venograms and diagnostic tests for VTE. All-cause deaths included fatal PE and deaths for other reason than PE.
From randomization up to 10 days after surgery or the day of mandatory venography, whichever came first

Secondary Outcomes (3)

Percentage of Participants Who Experienced "Major" VTE or All-cause Death
From randomization up to 10 days after surgery or the day of mandatory venography, whichever came first
Percentage of Participants Who Experienced Clinically Relevant Bleedings
From first study drug injection up to 3 days after last study drug injection
Percentage of Participants Who Required the Initiation of Curative Anticoagulant or Thrombolytic Treatment After VTE Assessment
From randomization up to 10 days after surgery or the day of mandatory venography, whichever came first

Other Outcomes (3)

Overview of deaths
From first study drug injection up to 3 days after last study drug injection
Platelets Count: Percentage of Participants With Potentially Clinically Significant Abnormalities [PCSA]
From first study drug injection up to 3 days after last study drug injection
Liver Function: Percentage of Participants With Potentially Clinically Significant Abnormalities [PCSA]
From first study drug injection up to 3 days after last study drug injection

Study Arms (2)

Semuloparin

EXPERIMENTAL

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

Drug: Semuloparin sodiumDrug: Placebo

Enoxaparin

ACTIVE COMPARATOR

Drug: EnoxaparinDrug: Placebo
