Active clinical trials for "Blood Coagulation Disorders"

This trial is conducted in Asia and Europe. The aim of this trial is to evaluate the intra-subject variability of thromboelastographic parameters (TEG® and ROTEM®) following two administrations of activated recombinant human factor VII in haemophilia patients in a non bleeding state. The TEG® parameters are: R time (Reaction Time), K time (K Time (arbitrary measurement)), a (a angle), MA (Maximum Amplitude) and LY30 (Lysis 30 min after MA) while the ROTEM® parameters are: CT (Clotting Time), CFT (Clot Formation Time), a (a angle), MCF (Maximum Clot Firmness) and LI60 (Lysis index 60 min after CT).

This trial is conducted in Asia. The aim of this trial is to evaluate the haemostatic efficacy of activated recombinant human factor VII in cirrhotic patients scheduled to undergo partial hepatectomy due to liver cancer or benign tumours.

This trial is conducted in Europe. The aim of this trial is to investigate the pharmacokinetics of three different single doses activated recombinant human factor VII in Caucasian and Japanese healthy subjects.

This trial is conducted in Africa, Asia, Europe, Oceania and North America. The aim of this trial is to evaluate the efficacy of activated recombinant human factor VII given in conjunction with standard therapy in the treatment of massive bleeding in subjects with severe blunt and/or penetrating trauma injury.

This trial is conducted in Europe. The aim of this trial is to investigate the pharmacokinetics (how the trial drug is distributed in the body) of NNC172-2021 administered subcutaneously, at two different dose levels, in healthy Japanese subjects.

This trial is conducted in Asia. The aim of this is to investigate the efficacy and safety of activated recombinant human factor VII (rFVIIa) in achieving haemostasis in patients with Dengue haemorrhagic fever (DHF).

The purpose of this study is to evaluate prospectively whether concentrate fibrinogen reduces blood losses, transfusion requirements and occurrence of clinical complications compared to cryoprecipitate in children after cardiac surgery with pump.

This trial is conducted in Europe and Asia. The aim of this clinical trial is to investigate the safety, pharmacokinetics (how the trial drug is distributed in the body) and pharmacodynamics (physiological effects of the drug on the body) of NNC 0172-0000-2021 administered intravenously and subcutaneously to healthy male subjects and subjects with haemophilia A or B

This trial is conducted in Europe and Asia. The aim of this clinical trial is to compare two recombinant factor VIII drugs, turoctocog alfa (recombinant factor VIII (N8)) with Advate®, in haemophilia A subjects, investigating the action and safety of the drugs.

Background: Bleeding and coagulopathy still accounts for the majority of early in-hospital deaths following trauma. There have been lately several published studies suggesting that higher transfusion ratios of fresh frozen plasma (FFP), platelets (PTL) and cryoprecipitate (CRYO) to red blood cell (RBC) are associated with survival advantages. However, the evidence comes from retrospective data limited by a significant number of unaddressed confounders. In addition, the use of blood products bears known and important risks of complications. Hypothesis: The adoption of a formula-driven transfusion practice with pre-defined ratios of FFP to PTL to RBC transfusion (1:1:1) is feasible and superior to current laboratory-guided transfusion practice in treating and/or preventing early coagulopathy improving survival rates in massively bleeding trauma patients . Objective: To exam the feasibility of implementing a pre-defined ratio of FFP to PTL to RBC (1:1:1) transfusion protocol and its impact on a population of bleeding trauma patients. Design: A two-year pilot feasibility randomized control trial at Sunnybrook Health Sciences Centre. Randomization: 70 patients are expected to be randomized to lab-driven or to formula-driven massive transfusion protocol and followed-up to 28 days or hospital discharge. Study outcomes: protocol violation; in-hospital mortality by exsanguination; death at 28 days; coagulation competence defined by current standard coagulation tests (INR & PTT < 1.5 times normal; PTL ≥ 50 and Fibrinogen ≥ 1.0) or clotting factor levels ≥ 30%; correlation of current standard coagulation tests with clotting factors levels; cessation of bleeding; incidence of ALI, sepsis, MOF, transfusion-related circulatory overload, transfusion reactions; Ventilator-free days; ICU & Hospital LOS; thromboembolic events. Intervention protocol: Transfusion of pre-defined ratios of FFP and PTL to RBC (1:1:1) (formula-driven) for the first 12h of hospitalization without coagulation tests guidance while patient is hemorrhaging or before if bleeding stops. Statistical analysis: protocol compliance rate and in-hospital mortality rates within 24h and at 28 days will be assessed using Chi-square test. ROC analysis will be used to analyze coagulation competence. Main expected outcomes: implementation of a formula-driven transfusion protocol is feasible and coagulation competence will be achieved faster and more efficiently in the study group.
