Active clinical trials for "Thrombosis"

Primary objective: To evaluate safety and tolerability, adverse events (AEs), vital signs, ECG, bleeding time, evaluation of antibody titer and safety laboratory tests Secondary objectives: To evaluate the pharmacokinetics and pharmacodynamics (platelet aggregation)of six ascending single intravenous doses of PR-15 in healthy volunteers

This is a randomized trial to compare intermittent compression devices with or without post-operative Arixtra (fondaparinux sodium) in women undergoing major abdominal surgery for known or presumed gynecologic malignancies. This trial seeks to determine if there is a difference in the rate of deep venous thrombosis between these two groups.

Several case reports indicate that the use of the antibiotic combination amoxicillin and clavulanic acid (AM-CLAVAC) can interact with warfarin pharmacodynamics. However, fever per se might also be responsible of these warfarin overdose reports, as well as the use of high dose paracetamol. The aim of the present study is to determine if AM-CLAVAC can increase the pharmacodynamics of warfarin among patients at steady state Double blinded cross over controlled study vs placebo performed in 12 evaluable patients treated with warfarin with an INR target 2 to 3 and a stable INR and a stable dose.

Primary objective: to characterize the pharmacokinetic and the pharmacodynamic profile after intravenous bolus injection of unfractionated heparin (UFH) after repeated sc 100 IU anti-Xa/kg (corresponding to 1 mg/kg) twice a day during 2.5 days (every 12±2hrs) administrations of enoxaparin in Caucasian healthy subjects. Secondary objective(s): to compare the pharmacokinetic and the pharmacodynamic profile between 3 different timing of administration of the UFH to assess the tolerability of the different anticoagulation protocols

Thrombosis is a significant medical complication in children with chronic diseases. The currently utilized treatments have many drawbacks which can lead to poor outcomes. More modern therapies are available but have not been systematically tested in children. This study will determine whether one such medication, bivalirudin is a safer and more effective alterative. This study will monitor what effects the drug has upon the child's body and how the body processes the study drug (absorption, metabolism and elimination). The study will also evaluate the drug's effectiveness by following how long it takes to dissolve the clot. The safety issues being monitored relate to any observations of major or minor bleeding episodes after taking the drug, and/or any other side effects.

The investigators plan to perform an exploratory study to investigate the effects of electro-stimulation of the legs on the symptoms and clinical findings of post thrombotic syndrome (PTS), as well as quality of life of patients with PTS. The investigators theorize that electro-stimulation will provide both a mechanical benefit via muscular contraction and increased venous outflow from the affected extremity, as well as an anesthetic effect, which the investigators anticipate will translate into improved symptomatic outcomes, quality of life (QOL) benefits.

To investigate the efficacy and safety of once daily enoxaparin as a "bridge" to warfarin for the outpatient treatment of acute deep venous thrombosis or pulmonary embolism.

To evaluate fondaparinux 2.5mg subcutaneously once daily for 45 days in the treatment of acute (recent) superficial thrombophlebitis.

This is a multicenter, randomized, open-label, assessor-blind, event-driven, non-inferiority program for efficacy with a study treatment duration of 3, 6 or 12 months in patients with confirmed acute symptomatic DVT without symptomatic PE (Einstein-DVT).

To evaluate the safety profile of alfimeprase as assessed by monitoring of adverse events, serious adverse events and major bleeding events for up to 120 minutes following the instillation of study drug to an occluded central venous access device.
