Filter by:We hypothesize that reduced dose of enoxaparin in elderly patients will result in reduced proportion of patients with therapeutic anti Xa activity and reduced clinical efficacy.
The primary objective is to: - demonstrate the efficacy of SR123781A in the prevention of venous thromboembolism (VTE) by the demonstration of a dose-response in patients undergoing total hip replacement surgery. The secondary objectives are to: - evaluate the safety of SR123781A in the prevention of VTE after elective total hip replacement surgery; and - to assess the SR123781A pharmacokinetic profile in patients undergoing elective total hip replacement surgery.
This study is phase 3 study for prevention of VTE in patients with abdominal surgery.
The purpose of this study is to assess if 10 mg BAY 59-7939, taken once daily as a tablet, is safe and can help prevent blood clots forming after a hip replacement operation.
The primary objective was to demonstrate the dose-response of Semuloparin sodium (AVE5026) for the prevention of Venous Thromboembolism [VTE] in patients undergoing total knee replacement [TKR] surgery. Secondary objectives were to evaluate the safety (incidence of major bleeding) of AVE5026, to document the efficacy and safety of AVE5026 post-operative regimens, and to assess the pharmacokinetic parameters of AVE5026.
The purpose of the study is to assess the occurrence of venous thromboembolism (blood clots), stroke, and heart attack in current users of ORTHO EVRA compared to current users of norgestimate-containing oral contraceptives with 35 mcg ethinyl estradiol with special attention to duration of use. The study uses data from the PharMetrics Patient-Centric Database and MarketScan database, which are US medical claims databases.
The purpose of this study is to assess if 10 mg BAY 59-7939, taken once daily as a tablet, is safe and prevent blood clot which may form after total hip replacement operation.
To determine the efficacy and to measure the complications of prophylactic anticoagulation using low-molecular weight heparin in adult cancer patients under palliative care
The purpose of this trial is to determine the comparative safety and efficacy of dabigatran etexilate 150 mg bid administered orally and warfarin as needed (pro re nata - prn) to maintain an International Normalised Ratio (INR) of 2.0-3.0 for 6 month treatment of acute symptomatic venous thromboembolism (VTE), following initial treatment (5-10 days) with a parenteral anticoagulant approved for this indication. This trial aims to demonstrate non-inferiority of dabigatran compared with warfarin in patients with acute symptomatic VTE. After achieving non-inferiority, this trial also aims to establish superiority (by means of hierarchical tests) of dabigatran over warfarin.
The results of the Prolong study, currently submitted for publication, show that patients with a first unprovoked venous thromboembolic event who have altered D-dimer levels, measured one month after anticoagulation with vitamin K antagonists is stopped, have a high rate of recurrences (about 14%) and a prolongation of anticoagulation is effective in reducing significantly this rate. Those patients with normal D-dimer (about 60% of all patients examined) have a low rate of recurrences (about 5%) and likely a prolongation of anticoagulation in all these patients cannot be recommended. In line with these results, the Prolong-Two study aims at assessing the predictive role for recurrence of D-dimer levels measured: a) during anticoagulation, b) one month after its withdrawal and c) periodically during follow up. Patients with a first unprovoked venous thromboembolism (including proximal deep vein thrombosis of a leg and/or pulmonary embolism) which are treated with vitamin K antagonists for not less than 6 months are considered for the study. D-dimer assay is performed during anticoagulation and patients with altered results continue the anticoagulation for 6 more months. Those with normal D-dimer stop the anticoagulant treatment and are again examined one month later. Anticoagulation is resumed for 6 more months in those patients with abnormal D-dimer results but is permanently stopped in those with a normal assay. The latter patients are examined and D-dimer assay performed again every two months to evaluate the natural history of the assay after anticoagulation is stopped and the possible predictive value for recurrence of a change of the assay during follow-up from normal to abnormal results.
