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.
Randomization had to take place just prior the first study drug injection (randomization ratio 1:1).
The total duration of observation per participant was 35-42 days from surgery broken down as follows:
Mandatory bilateral venography of the lower limbs had to be performed 7 to 11 days after surgery.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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:
|
|
| Enoxaparin | Active Comparator | 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 |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Semuloparin sodium | Drug | 0.3 mL (0.2 mL if SRI) solution in ready-to-use 0.5 mL pre-filled syringe Subcutaneous injection |
|
| Measure | Description | Time Frame |
|---|---|---|
| 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 |
| Measure | Description | Time Frame |
|---|---|---|
| Percentage of Participants Who Experienced "Major" VTE or All-cause Death | "major" VTE included any proximal DVT, symptomatic distal DVT and non-fatal PE as confirmed by the CIAC. | 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 |
| Measure | Description | Time Frame |
|---|---|---|
| Overview of deaths | All deaths were centrally and blindly reviewed by the CIAC and classified as fatal PE, fatal bleeding, cardiovascular death or other based on relevant documentation (e.g. autopsy report). | 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] |
Inclusion Criteria:
- Knee replacement surgery or revision of at least one component of a knee prosthesis implanted ≥ 6 months prior to study entry.
Exclusion Criteria:
The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

| Enoxaparin | Drug | 0.3 mL (0.2 mL if SRI) solution in ready-to-use 0.5 mL pre-filled syringe Subcutaneous injection |
|

| Placebo | Drug | 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 Subcutaneous injection |

Bleedings were centrally and blindly reviewed by the CIAC and classified as:
|
| 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 | Initiation of curative anticoagulant or thrombolytic treatment after VTE assessment was defined from investigator's answer to the question "was the subject treated for VTE?" asked after the diagnostic tests for suspected VTE and after the mandatory venography. | From randomization up to 10 days after surgery or the day of mandatory venography, whichever came first |
PCSA are abnormal values considered medically important by the Sponsor according to predefined criteria based on literature review. Threshold for platelet counts was defined as <100 Giga/L. |
| 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] | Thresholds were defined as follows:
Cases with ALAT >3 ULN and TB >2 ULN (not necessarily concomitant) were evaluated by a blinded independent adjudicator to determine if they met Hy's law criteria. | From first study drug injection up to 3 days after last study drug injection |
