Active clinical trials for "Blood Coagulation Disorders"

This trial was conducted in Europe. The aim of this trial was to investigate safety and pharmacokinetics of escalating single doses of catridecacog (recombinant factor XIII, rFXIII) in healthy volunteers.

The aim of the present study is to investigate changes in inflammatory status and incidence of infection after extreme aerobic physical stress (participation in a marathon). In addition, the impact of marathon running on the hemostasis and muscular state will be evaluated. Changes at the inflammatory, muscular, and rheological level will be related to ingestion of oral hydrolytic enzymes and bioflavonoids.

The purpose of this research is to determine whether giving severely injured adults a drug called tranexamic acid (TXA) as soon as possible after injury will improve their chances of survival and their level of recovery at six months. After severe injury, a person may have uncontrolled bleeding that places them at high risk of bleeding to death. Coagulation (the formation of blood clots) is an important process in the body that helps to control blood loss. Up to a quarter of people that are severely injured have a condition called acute traumatic coagulopathy. This condition affects coagulation and results in the break down of blood clots (fibrinolysis) that can lead to increased blood loss and an increased risk of dying. TXA is an anti-fibrinolytic drug that might help to reduce the effects of acute traumatic coagulopathy by preventing blood clots from breaking down and helping to control bleeding. In Australia, TXA is approved for use by the Therapeutic Goods Administration (TGA) to reduce blood loss or the need for blood transfusion in patients undergoing surgery (i.e. cardiac surgery, knee or hip arthroplasty). Recent evidence from a large clinical trial (CRASH-2) showed early treatment with TXA reduced the risk of death in severely injured patients, however the majority of patients involved in the study were injured in countries where prehospital care is limited and rapid access to lifesaving treatments is limited compared to that available in countries like Australia and New Zealand. It is unclear whether TXA will reduce the risk of death to the same degree when it is given alongside other lifesaving treatments that are available to patients soon after injury in these countries. The hypothesis is that TXA given early to injured patients who are at risk of acute traumatic coagulopathy and who are treated in countries with systems providing advanced trauma care reduces mortality and improves recovery at 6-months after injury.

Trauma is the leading cause of death in people 44 years of age or younger. After major trauma, such as following high-speed motor vehicle collision, bleeding coupled with clotting defects is responsible for most of deaths in the first hours of hospital admission. Of note, these bleeding-related deaths are potentially preventable. Accordingly, the initial in-hospital management of severely injured patients focuses on stopping bleeding, replacing blood loss and correcting clotting defects. Recently, animal and human research demonstrated that one of the major clotting defects following injury and bleeding is the drop in blood levels of fibrinogen (a clotting factor), which is detected on hospital admission in severely injured patients. These low fibrinogen levels are associated with increased blood transfusion and death. However, in North America, the standard of care for replacing low fibrinogen requires the use of cryoprecipitate, which is a frozen blood product with long preparation time, and similarly to other blood products, carries the risk of viral transmission and transfusion complications. Alternately, many Europeans countries where cryoprecipitate has been withdrawn from the market due to safety concerns, use fibrinogen concentrate. Fibrinogen concentrate undergoes pathogen inactivation, which is a process to eliminate the risk of transmitting viruses, bacteria and parasites, is likely a safer and faster alternative to cryoprecipitate. In Canada, fibrinogen concentrate is licensed for congenital low fibrinogen only. Although preliminary data suggest that fibrinogen supplementation in trauma is associated with reduced bleeding, blood transfusion, and death, the feasibility, safety and efficacy of early fibrinogen replacement remains unknown. We proposed to conduct a feasibility randomized trial to evaluate the use of early fibrinogen concentrate against placebo in injured patients at our trauma centre. A pilot trial is necessary to demonstrate the feasibility of rapidly preparing, delivering, and infusing fibrinogen concentrate as an early therapy to prevent excessive bleeding in trauma. This feasibility trial will provide preliminary safety and clinical outcome data to inform the design of larger trials; which ultimately aims to prevent bleeding-related deaths in the trauma population.

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.

This trial is conducted in Asia, Europe and North America. The purpose of the trial is to evaluate the safety and efficacy of turoctocog alfa in prevention and treatment of bleeds in previously untreated children with haemophilia A.

This trial is conducted in North America. The aim of this trial is to compare the safety and efficacy of activated recombinant human factor VII in patients with haemophilia A or B undergoing major surgical procedures.

In this 94 healthy subjects Phase I clinical trial, we assess the clinical profile of Anfibatide, a specific glycoprotein Ib antagonist. This study represents the first clinical evidence that Anfibatide exhibits strong anti-platelet effects, excellent reversibility, and low bleeding potential in healthy human subjects.

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.

The high percentage of failure using available non-surgical options to treat menorrhagia in women with bleeding disorders shows a continuing need for innovative treatments. This has led to development of this protocol in order to make available tranexamic acid as a potentially effective menorrhagia therapy option in women with an underlying bleeding disorder. We anticipate that Tranexamic Acid may be a beneficial choice for controlling menorrhagia in bleeding disorder patients.
