Filter by:The aim of this study is to verify, through clinical examination and doppler, the non-inferiority of the drug test (heparin sodium 5.000UI/0.25 mL - HIPOLABOR) in relation to the drug compared (heparin sodium 5.000USP/mL - APP) in preventing the development of venous thromboembolism (VTE) in patients undergoing surgery for medium risk for the development of this pathology.
Fondaparinux is a parenteral anticoagulant drug and is approved for the prevention of venous thromboembolism in high risk medical patients. A relevant proportion of medical patients have moderate to severe renal insufficiency, which is an independent risk factor for bleeding. This risk may be further increased when low molecular weight heparin or fondaparinux are administered in patients with severe renal insufficiency, defined by a creatinine clearance of lower than 30 mL/min. No clear indications are available to reduce such risk in patients who require thromboprophylaxis. A lower dose of fondaparinux, 1.5 mg daily, has been recently approved for the prevention of venous thromboembolism in the specific population of patients with a creatinine clearance between 20 and 50 mL/min (European Marketing Authorization). However, there are to our knowledge no clinical studies that have assessed the safety and efficacy of this reduced dosage in medical patients.
This is a prospective study with the following objectives: Primary Objective: 1. To estimate the prevalence of unsuspected VTE in oncology patients on routine staging CT scans of the thorax, abdomen and pelvis. Secondary Objectives: 2. To identify symptoms commonly associated with VTE that are present in cancer patients undergoing routine staging CT scans with findings of unsuspected VTE. 3. To identify the risk factors and demographic characteristics in outpatient cancer patients associated with the development of unsuspected VTE. 4. To determine the incidence of recurrence of new VTE in patients with unsuspected VTE at 3 and 6 months of follow-up.
The purpose of this study is to examine the superiority of YM150 to the placebo and to evaluate the dose-dependent response of YM150 in patients undergoing elective total knee replacement surgery.
The purpose of this study is to examine the superiority of YM150 to the placebo and to evaluate the dose-dependent response of YM150 in patients undergoing elective total hip replacement surgery.
The Venous thromboembolism (VTE) disease is very frequent, mainly as complications of medical diseases and surgical procedures. It has high prevalence and can lead to severe complications such as pulmonary embolism and postthrombotic syndrome. Although its incidence has been decreasing in recent years, the EP and DVT is still a major public health problem, especially in advanced age. The tracking of this disease through imaging tests in asymptomatic patients does not seem to be a cost-effective, further treatment of complications is expensive and subject to no satisfactory answers are not completely effective in regard to late complications. Therefore, according CAIAFA & BASTOS (2002), effective prophylaxis is the best strategy. The type of prevention to be used should be based on the risk of developing VTE, ie low, medium or high. Framework for a category of risk for the indication of prophylaxis, each patient should be evaluated individually and carefully to the risk of developing VTE. Maffei et al. (2005) describe the "Standards for Clinical Guideline for the prevention, diagnosis and treatment of deep vein thrombosis." According to the guide, the concentration of heparin in 5.000UI is indicated for cases of moderate-risk surgeries. Are classified as "moderate risk" to more surgery (general, gynecological and urological) in patients 40 to 60 years without additional risk factors, and the magnitude of any surgery in patients under 40 years of age who use estrogen ( Annex 01). The dosing schedule chosen in this study also follows the recommendation of the guide and is universally used . According to Maffei et al. (2005), the diagnosis of VTE must be initiated by the history and physical examination, and then must be performed ultrasound Doppler of lower limbs. Thus, the ultra-sonography/doppler examination will be done at the beginning and end of treatment and physical examination will be done periodically throughout the period of monitoring. Following the guidelines proposed by the literature consulted, was established to test this methodology, which aims to demonstrate the non inferiority clinical heparin sodium 5.000UI / 0.25 mL sodium heparin on 5.000UI / 1.0 mL, both produced by Blausiegel Industry and Trade Ltda. in reducing the incidence of VTE. The two formulations are produced from the same material, but have different drug concentrations. Thus, there is a need to scientifically prove that the therapeutic activity and safety of the product test is non-inferior to the comparator drug (APP heparina - 5.000 USP/mL), allowing the sponsoring company to obtain the registration of the product in the concentration of 5000UI /0.25 mL in ANVISA at the proposed therapeutic indication in the study.
The purpose of this study is to evaluate the efficacy and safety of various doses of YM150 (the experimental drug) compared to enoxaparin in the prevention of venous thromboembolism in patients that are undergoing elective hip replacement surgery.
This clinical trial will investigate the hypothesis that D-Dimer testing can be successfully used to tailor the duration of OAT in patients after an unprovoked episode of deep venous thrombosis (DVT) using a prospective, randomized, and controlled design.
This pilot study is designed to determine the feasibility of conducting a randomized clinical trial comparing fondaparinux sodium (Arixtra) once daily with enoxaparin (Lovenox®) twice daily with respect to preventing deep vein thrombosis (DVT) and pulmonary embolism (PE) after bariatric surgery in obese patients.
Enoxaparin is a type of low molecular weight heparin (LMWH), or anticoagulant, used to prevent and treat blood clots. Formation of blood clots, or venous thromboemboli (VTE) in pregnancy can have dangerous and even life-threatening effects on the mother and fetus. Enoxaparin is the preferred medicine to prevent clotting in pregnant patients who are at risk for VTE, because it has been studied to be safe and effective in pregnancy without any harms to the fetus. Although this medication is routinely used and is recommended by several prominent medical groups, the optimal dosing for prevention of VTE is still unclear. The range of standardly prescribed dosing regimens of Enoxaparin includes 40mg daily and 1mg/kg daily, but these two dosing strategies have never been compared in a head to head fashion.
