Efficacy of Bemiparin Versus Enoxaparin in the Treatment of DVT

• Status: Completed
• Trial end date: 2015-05-01
• Target enrollment: 0
• Participant gender: All

Summary

Deep-vein thrombosis (DVT) is a common but under-diagnosed medical condition that occurs when a thrombus forms in one of the large veins, usually in the lower limbs, leading to either partial or complete blocked circulation. The condition may progress to severe health complications, such as pulmonary embolism (PE), if not diagnosed and treated in a timely and effective manner.

The goal of the therapy for lower-extremity DVT is to prevent the extension of thrombus and pulmonary embolism in the short term and to prevent recurrent events in the long-term. Although anticoagulant therapy decreases the risk of recurrent thrombosis, the treatment also increases the risk for major hemorrhage.

This trial aims to optimize the current medical knowledge on the effectiveness and safety of two low molecular weight heparins, bemiparin and enoxaparin in the treatment of deep vein thrombosis.

Criteria

Inclusion Criteria:

1. Patients with acute deep-vein thrombosis of the leg (DVT) with symptoms of less than 14 days confirmed by complete compression ultrasound (cCUS) within 48 h prior study starting .

2. Males and females aged ≥18 years

3. Patients who have given their written informed consent.

Exclusion Criteria:

Specific

1. History and presence of familial bleeding diathesis, presence of active bleeding contraindicating anticoagulant therapy, as well as presence of clinically relevant coagulation - and clotting factor disorder,and thrombocytopenia

2. Patients having undergone thrombectomy, having had insertion of a caval filter or who were treated with a fibrinolytic agent to treat the current episode of DVT

3. Treatment with heparin (fractionated or unfractionated), fondaparinux or vitamin K antagonist or warfarin for treatment of DVT for more than 48 h prior to enrolment

4. Long-term treatment with vitamin K antagonists, i.e. for atrial fibrillation, myocardial infarction or cardiomyopathy

5. Isolated distal calf vein thrombosis

6. Isolated superficial vein thrombosis

7. Any other symptomatic venous thromboembolism beside of DVT

8. Known hypersensitivity to heparin (including other pig-derived substances), to the study medications and heparin-derivatives including other LMWHs, warfarin and/or to the active ingredient or any excipient of the study medications

9. Concurrent treatment with platelet function inhibitors (such as acetylsalicylic acid, ticlopidine, clopidogrel, NSAID), fibrinolytic agents and other anticoagulant agents, Glycoprotein IIb/IIIa receptor- antagonists, nitro-glycerine iv, systemic glucocorticoids, penicillin in high doses, dextran, ascorbic acid, digitalis, tetracycline, medical products that could increase the potassium plasma level

10. History of documented or suspected heparin-induced thrombocytopenia (HIT I and II) or platelet count less than 100,000 platelets per mm3

11. Ischaemic stroke one month prior to enrolment

12. History of or active intracranial disorder (cerebral vascular aneurysm, arterio-venous malformation or cerebral neoplasm), history of haemorrhagic stroke or other intracranial bleeding 6 months prior to enrolment, active haemorrhage or increased risk of bleeding due to impaired haemostatics or organ lesion (e.g. peptic ulcer, hepatic failure, haemorrhagic stroke, macroscopic visible urogenital bleeding, cerebral vascular aneurysm or cerebral neoplasm) 1 month prior to enrolment.

13. Uncontrolled arterial hypertension: systolic blood pressure > 200 mmHg and diastolic blood pressure > 105 mmHg.

14. Severe impairment of pancreas function, history of gastro-duodenal ulcer disease, nephrolithiasis and/or ureterolithiasis, choroid and retinal vascular disease, suspected vascular retinopathy, vitreous haemorrhage or other intraocular bleedings, or any organic lesion with an increased risk of bleeding.

15. Significant liver disease (e.g. acute hepatitis, chronic active hepatitis, hepatic cirrhosis, hepatic encephalopathy) or liver enzymes (ALT and/or AST) > 5x ULN.
