Active clinical trials for "Blood Coagulation Disorders"

This trial is conducted in Europe. The aim of this clinical trial is to investigate the safety, local tolerability and pharmacokinetic profile (the determination of the concentration of the administered medication in blood over time) of long acting activated recombinant human factor VII when injected subcutaneously (under the skin).

This phase II study was a prospective, randomized, open-label, multi-center study in the United States, involving patients from 18 to 70 years of age, comparing Anavip (Antivenin Crotalinae [pit viper] equine immune F(ab)2; Instituto Bioclon, Mexico City, Mexico) against CroFab (Protherics Inc., Nashville, Tennessee), the only currently approved product for treatment of Crotalinae (pit viper) envenomation in the US. The study was designed to evaluate the hypothesis that lasting correction of snakebite induced thrombocytopenia and hypofibrinogenemia are possible following correction with F(ab)2 antivenom, by analyzing in detail the relationships among platelet count, fibrinogen, venom levels, and antivenom levels in subjects presenting with thrombocytopenia following crotaline viper envenomation. In the study we expected to see a fall in platelet count following Fab treatment, commensurate with that reported in the past. We hypothesized that following F(ab)2 treatment there would be a slower drop in post-treatment platelet counts, with a relatively higher platelet count at any given point in the follow-up period. We further hypothesized that an initial rise and later fall in platelet count would correspond with rise and fall in antivenom levels, and would be mirrored by concurrent drop and rise in levels of unbound circulating venom.

The purpose of this study is to evaluate efficacy, safety and tolerance of Beriplex® P/N (Kcentra) compared with plasma in regard to rapid reversal of coagulopathy induced by vitamin K antagonists in subjects who require immediate correction of international normalized ratio (INR) because of emergency surgery.

Open-heart surgery frequently results in abnormal clotting, which in turn results in excessive blood loss and the need for transfusion of multiple blood products to patients and leads to adverse outcomes. Prompt identification of any clotting abnormalities after cardiac surgery reduces blood loss and blood product transfusion and may improve outcomes. Currently, however, this monitoring is dependent on standard laboratory-based tests of clotting that have a long turnaround time (30-45 min) and do not measure some important aspect of clotting. There are now other monitoring options that are carried out at patients' bedside, providing results more quickly than standard laboratory tests (within 2-5 minutes for some), and measure more aspects of clotting, providing more information on possible causes of any abnormalities. In this study, we will compare the cost-effectiveness of two of these newer monitoring techniques with standard laboratory-based tests by assigning 150 patients who will be undergoing open-heart surgery to one of the three monitoring techniques (50 patients will be assigned by chance to each group). In each group, an explicit algorithm based on the monitoring technique of that group will be used to guide all transfusion decisions. Between-group differences in number of units of blood products transfused (primary outcome), amount of blood loss, rate of adverse events, and cost of monitoring will be measured. The objective of the study is to determine which of the three methods is most cost-effective in terms of these outcomes.

This trial is conducted in Europe. The aim of this trial is to evaluate the efficacy and safety of two dose schedules of activated recombinant human factor VII in treatment of joint bleeds in haemophilia patients with inhibitors.

This trial was conducted in the United States of America (USA). The aim of this trial was to investigate safety and pharmacokinetics of escalating single doses of catridecacog (recombinant factor XIII, rFXIII) in patients with congenital factor XIII deficiency.

XIENCE 28 Global Study is a prospective, single arm, multi-center, open label, non-randomized trial to further evaluate the safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS, XIENCE PROX EECSS, XIENCE ProA EECSS or XIENCE Sierra EECSS of coronary drug-eluting stents

Patients with acute ST-segment elevation myocardial infarction (STEMI) have an elevated risk of stroke, most of which are cardio-embolic in origin as a result of left ventricular (LV) thrombus formation. Anterior-wall location of a MI, in particular, can lead to the complications of LV aneurysm and/or thrombus, which some estimate occurs in approximately up to one-third of individuals within the first 2 weeks following an anterior MI. In the absence of anti coagulation, the risk of embolization in patients with a documented LV thrombus has been reported to be between 10 and 15 percent [3]. Although there are no randomized trials evaluating the efficacy of anticoagulation in patients with an LV thrombus after MI, observational studies provide substantial supporting evidence for the recommendation to anticoagulate patients with documented LV thrombus in order to reduce the risk of embolization. The observation that most events occur within the first three months from the MI forms the basis for the recommendation that anticoagulant therapy should be started early and continued for at least three to six months after myocardial infarction. Currently the practice guidelines recommend anticoagulation after MI only in certain settings such as the presence of LV thrombus or atrial fibrillation. To date there are no data on the use of novel oral anticoagulants (NOACS) for stroke prevention in the setting of LV thrombus after acute MI. The proposed aim of this randomized open label non inferiority clinical trial is to assess whether apixaban is as effective as VKA for the treatment of LV thrombus after acute ST segment elevation MI. Population: Patients with evidence of LV thrombus as assessed by trans-thoracic echocardiography (TTE) 3 to 7 days post admission for acute ST-elevation MI Intervention: The patients will be randomly assigned to treatment with apixaban or s.c enoxaparin 1mg/Kg BID followed by dose-adjusted warfarin to achieve a target international normalized ratio (INR) of 2.0 to 3.0 for 3 months. The study Outcomes are the presence of LV thrombus as assessed be echo, major bleeding, and stroke or systemic embolism and death from any cause.

This trial is conducted in Japan. The aim of this clinical trial is to investigate the pharmacokinetics (the effect of the investigated drug on the body) and safety of turoctocog alfa (recombinant factor VIII (N8)) in Japanese subjects with haemophilia A.

The purpose of this study is to evaluate efficacy, safety and tolerance of BERIPLEX® P/N (Kcentra) compared with plasma in regard to rapid reversal of coagulopathy induced by coumarin derivatives in subjects who require immediate correction of INR (International Normalized Ratio)and to stop an acute major bleeding.
