E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective is to achieve a prophylactic anticoagulation level within 7(+/-1) hours after Baseline. The parameter to define the anticoagulation level is aPTT and will be measured at 7(+/-1) hours for the Primary Objective. |
|
E.2.2 | Secondary objectives of the trial |
- Assessment of thromboembolism after 7 days
- Assessment of bleeding complications within 3 - 7 days
- Assessment of biological and clinical parameters
- Maintenance of the target aPTT within 7 days
- Need for readjustment in case of non maintenance of the target aPTT within 7 days
- Assessment of transfusion of any blood products
- Parameters predictive for an effective Argatroban dose
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patient at risk for thrombosis or thromboembolic complications with the need of prophylactic antithrombotic therapy
- Age: 18 – 85 years
- Prohylactic anticoagulation (aPTT: 45 – 60 sec) is not achieved with a heparin dosage of 1.200 IU per hour after two hours of infusion
|
|
E.4 | Principal exclusion criteria |
- If patient needs an aPTT-level > 60 sec for any reason
- Active bleeding
- Risk for bleeding higher than risk of thromboembolic event as anticipated by the physician
- Planned surgical procedure with the need for interruption of antithrombotic therapy within the next 24 hours
- Inevitable lethal course
- Severe Liver failure: Quick < 30 %
- Pregnancy
- Planned peridural or spinal anaesthesia during the study
- Patient with known refusal of a participation in this clinical trial
- Active participation in another clinical trial
- Any condition, including the presence of laboratory abnormalities, which would place the subject at unacceptable risk if he/she were to participate in the study or confound the ability to interpret data from the study
- Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
