Active clinical trials for "Thromboembolism"

This prospective randomized study aims to determine whether intermittent pneumatic compression (IPC), 75 patients, beneath functional bracing compared to treatment-as-usual in plaster cast, 75 patients, can reduce the Venous Thromboembolism (VTE) incidence and promote healing of sutured acute Achilles tendon ruptures. At two weeks post surgery, the IPC intervention will be ended and both patient groups will be immobilized in an orthosis until follow-up at six weeks. The endpoint of the first part of the study is VTE events. The primary outcome will be the DVT-incidence at two weeks, assessed using screening compression duplex ultrasound (CDU) by two ultrasonographers masked to the treatment allocation. Secondary outcome will be the DVT-incidence at 6 weeks. 1) Deep Vein Thrombosis (DVT) detected by CDU , 2) isolated calf muscle vein thrombosis (ICMVT) detected by CDU, 3) symptomatic DVT or ICMVT detected by CDU, 4) symptomatic pulmonary embolism detected by computer tomography. The endpoint of the second part of the study is tendon healing quantified at 2 weeks by microdialysis followed by quantification of markers for tendon repair. The endpoint of the third part of the study is the functional outcome of the patients at one year post-operatively using four reliable and valid scores, i.e. the Achilles tendon Total Rupture Score (ATRS), Physical Activity scale (PAS), Foot and Ankle Outcome Score (FAOS) and EuroQol Group's questionnaire (EQ-5D) as well as the validated heel-rise test.

Study Objective: To assess the value of Rivaroxaban for the prevention of venous thromboembolism (VTE) after knee arthroscopy (KA) taking the placebo as standard of reference. Study Population: Patients undergoing therapeutic KA at the study Centers, irrespective of the type and duration of the procedure, will be eligible for the study. Study Design: Multicenter, randomized, double blind superiority, phase II trial comparing two arms: (R-7d) Rivaroxaban (10 mg od os) for 7 days (PL-7d) Placebo for 7 days. Follow-up: 3-month period after the randomization Standard of Reference:Placebo will be the standard of reference in accordance to international guidelines Study length May 2012-December 2012 Total patients number: 500 patients Primary Efficacy End-Point: Occurrence in the 3-month period after the randomization of at least one of the following events, objectively proven (by means of CCDU; multi-slice chest TC-angio; autopsy, if necessary, or clinical ground): All-cause mortality Symptomatic VTE Asymptomatic proximal DVT Secondary Efficacy End-point: • Combined incidence of all DVT plus symptomatic PE Primary Safety End-point: Incidence of major bleedings. Secondary Safety End-point: Overall incidence of bleeding

The study will describe the short-term effects the study drug, rivaroxaban, has on the body when a patient is switched from enoxaparin injection (by needle) to oral rivaroxaban (by mouth) for the prevention of blood clotting in the veins after elective total hip or total knee replacement surgery. After providing written informed consent, screening procedures will be completed to assess eligibility. After enrollment, all patients will be switched from enoxaparin to rivaroxaban. Blood samples for the short-term effects of rivaroxaban will be taken at various times while in the subacute unit. At the time of discharge, if the study doctor feels it is appropriate, an adequate supply of rivaroxaban will be provided to complete the full course of therapy. Upon completion of rivaroxaban therapy, all patients will be required to have final study procedures performed. Safety evaluations at the final visit will include clinical blood laboratory tests, a physical examination, urine pregnancy test (if applicable), recording of any adverse events including details regarding any bleeding episodes or blood clot events, and assessment of the surgical wound. All patients will return any unused study medication and study participation will be complete.

The objective of this study is to assess the efficacy, safety and dose-response relationship of DU-176b compared with placebo for the prevention of venous thromboembolism in patients after elective total knee arthroplasty.

The primary objective of this study is to determine whether a dose-adjusted prophylaxis fondaparinux regimen of 2.5 milligrams (mg) subcutaneously administered every (q) 48 hours (hr) in patients with renal failure achieves peak and trough levels similar to patients with normal renal function, and protects patients from developing venous thromboembolism (VTE). Our hypothesis is that a dose-adjusted fondaparinux regimen, which extends the dosing interval from q24 to q48 hr, in patients with estimated creatinine clearance of < 30 ml/min, will be safe and effective.

The use of a new generation low molecular weight heparin (Bemiparin)and the well known LMWH (Enoxaparin) after Caesarean sections and vaginal deliveries in a risky group patients for venous thrombosis.

The objective of this study is to assess the efficacy and safety of DU-176b compared with enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total knee arthroplasty.

Currently standard of care for preventing blood clots in total knee replacement patients is the drug Fragmin which is a daily injection for 10 days after surgery. Patients are in hospital for 3 to 5 days after total knee replacement surgery and patients are taught in hospital to do their injections. The investigators would like to introduce the drug Pradax. Pradax is a Health Canada approved once a day, oral drug that may prevent blood clots in the patient's leg. In this study the patient will receive the standard of care injection drug Fragmin while in hospital but on discharge home the patient will take the oral drug Pradax daily (2 tablets 110mg) for 10 days.

The purpose of this study is to assess different doses of a new drug (BAY 59-7939), taken as a tablet, are safe and can help prevent blood clots forming after a hip replacement operation. Patients undergoing hip replacement surgery are at risk of developing blood clots. To reduce this risk treatment to prevent clots forming is routinely given. The current treatments can include injections under the skin or other treatments that need frequent blood tests to monitor levels of drug in the body. Therefore there is a need for new drugs, which are easier to give and need less monitoring.

Patients undergoing surgery, especially hip and knee surgery, are at high risk for VTE. The administration of drugs for thromboprophylaxis, such as heparins, significantly lowers that risk, but heparins have to be applied by injections below the skin. The purpose of this study was to compare the safety and efficacy of BAY 59-7939 with the safety and efficacy of the licensed drug enoxaparin and to find the optimal dose of BAY 59-7939 for the anticipated phase III trials. Enoxaparin, a so-called low molecular weight heparin, is approved and widely used in the area of thromboprophylaxis and was given once daily subcutaneously. In this study 5 different doses of the investigational drug BAY 59-7939 were tested in comparison to Enoxaparin. The following doses of BAY 59-7939 were tested: 2.5 mg twice daily (5 mg total daily dose); 5 mg twice daily (10 mg total daily dose), 10 mg twice daily (20 mg total daily dose), 20 mg twice daily (40 mg total daily dose) and 30 mg twice daily ( 60 mg total daily dose). This study ran for approximately 7 months in a number of countries. In total, 726 patients were enrolled in this study.
