BCD-080-2

Details and patient eligibility

About

The purpose of the study is to prove equivalence of efficacy and safety of BCD-080 and Clexan for deep vein thrombosis and embolism prophylaxis at orthopedic surgeries.

Full description

The study will include 116 patients who are planned for hip or knee replacement. Patients will randomized in 2 groups. 1-st group will receive BCD-080 at dose 30 mg every 12 hours during 14 days after surgery, 2-d group will receive Clexane at the same dose. Efficacy assessment will include frequency of deep vein thrombosis (DVT) (proximal and/or distal; symptomatic or asymptomatic), symptomatic nonlethal thromboembolia of the pulmonary artery (PATE) and venous thromboembolism death. Safety assessment will include frequency of "big", "small" and other bleedings and frequency of heparin induced thrombocytopenia.The assessment of efficacy and safety parameters will be made during the treatment and follow-up period (till 60 day).

5. Gastric or duodenal ulcer or other erosive and ulcerative lesions of gastrointestinal tract
6. Recent ischemic stroke
7. Uncontrolled severe hypertension; that is, all cases of hypertension, in which blood pressure decrease cannot be achieved with the use of combination of 3 antihypertensive drugs, compulsorily including a diuretic, and non-drug methods of correction (salt-free diet, graduated exercise); or if the results of two successive measurements of supine arterial blood pressure with an interval of 15-30 minutes, systolic blood pressure> 180 mm Hg. or diastolic blood pressure> 105 mm Hg
