E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Healthy male volunteers. Study assessing the effect of a single 50IU/Kg dose of Beriplex on the anticoagulant effect of Dabigatran. This is of interest when rapid reversal of its effect is mandated. E.g. in the case of Bleeding or when rapid surgical intervention is necessary. |
|
E.1.1.1 | Medical condition in easily understood language |
Reversal of the anticoagulant effect of Dabigatran. |
|
E.1.1.2 | Therapeutic area | Analytical, Diagnostic and Therapeutic Techniques and Equipment [E] - Therapeutic techniques [E02] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether a single dose of Beriplex (PCC 50 IU/Kg) is effective in reversing the anticoagulant effect of Dabigatran Etexilate 300mg b.i.d. taken for 2.5 days. As measured by the shed blood and washed blood method. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Healthy males • Age between 18 and 50 years • Weight <100 kg • Signed informed consent
|
|
E.4 | Principal exclusion criteria |
Exclusion criteria are: • History of allergic reaction to blood products • Current participation in any other investigational drug study or within the past 30 days • Increased bleeding tendency or history of thrombosis • Anticoagulant medication, platelet aggregation inhibitors or NSAIDs • Use of any medication 14 days before start of dabigatran intake
|

E.5 End points |
E.5.1 | Primary end point(s) |
The shed blood method: during 4 minutes blood will be collected from a 5.0x1.0mm cut in skin of the volar surface of the forearm. Fibrinopeptide A will be measured as well as the total volume of blood collected. The washed blood method: during 15 minutes blood will be collected from a 3.5x1.0mm cut in the skin of the volar surface of the forearm. This is done by placing a plexiglas chamber over the wound that is continuously flushed with saline attached to a fraction collector filling a 96 well plate for spectrometry. The time untill bleeding stops (bleeding time) can be determined as well as the total amount of blood loss as the Area under the curve (AUC). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
This will be done at 4 timepoints: baseline, after the last dose of Dabigatran, 30 minutes after PCC, 6 hours after PCC. After cross-over this is repeated. |
|
E.5.2 | Secondary end point(s) |
aPTT, PT, Diluted thrombin time (Hemoclot), Endogenous thrombin generation, pre- and post factor II, VII, IX, X |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Baseline, after last dose of Dabigatran, immediately after PCC, 30 minutes after PCC, 1-2-4-6 hours after PCC, 24 hours after PCC. |
