E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the hemostatic efficacy of Beriplex® P/N and plasma in preventing excessive hemorrhages during emergency surgical or invasive interventions in subjects who have a deficiency of vitamin K-dependent coagulation factors II, VII, IX, X and proteins C and S acquired from oral anticoagulation.
CO-PRIMARY OBJECTIVE To compare efficacy of Beriplex® P/N and plasma in rapidly reducing pre-operative international normalized ratio (INR) values between the 2 treatment groups at 30 minutes after end of infusion. |
|
E.2.2 | Secondary objectives of the trial |
-To compare the plasma levels of coagulation factors II, VII, IX, and X, protein C, and protein S between the 2 treatment groups -To document the time from start of infusion until INR correction for both treatment groups -To document the time from randomization until INR correction for both treatment groups -To compare INR between the 2 treatment groups at 30 minutes from start of infusion, -To compare the use of non-study prescribed blood products, additional FFP and/or hemostatic agents for coagulation in both treatment groups, - To compare predicted estimated blood loss versus actual estimated blood loss for intended procedure between the 2 treatment groups, - To compare the transfusion requirement intraoperatively and during the 24 hours from start of infusion, -To compare the volume and duration of wound drainage, - To determine the safety and tolerability of Beriplex® P/N compared to that of plasma.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Male and female subjects ≥ 18 years - Subjects who have received oral inticoagulation therapy (e.g. warfarin, acenocoumarol or phenprocoumon) and in whom either an emergency surgical or an invasive intervention is indicated. Due to the nature of the procedure, withdrawal of anticoagulation therapy and plasma are also indicated, - INR ≥ 2 within 3 hours before start of study treatment - Informed consent has been obtained
|
|
E.4 | Principal exclusion criteria |
- Subjects with emergency surgical procedures in which according to the surgeon's clinical judgment, an accurate estimate of blood loss is not possible (e.g. ruptured aneurysm), - Administration of intravenous vitamin K more than 3 hours or administration of oral vitamin K more than 6 hours prior to infusion of study treatment, - Expected survival of less than 3 days, - Acute trauma for which reversal of vitamin K antagonists alone would not be expected to control an acute bleeding complication and/or control the acute bleeeding event, - History of thrombotic event, myocardial infarction, unstable angina pectoris, cerebral vascular accident, transient ischemic attack, severe peripheral vascular disease, disseminated intravascular coagulation within 3 months of enrollment. - Known history of antiphospholipid antibody syndrome or lupus anticoagulant antibodies, - Suspected or confirmed sepsis at time of enrollment - A previous thromboembolic event within 30 days prior to inclusion into the study - Administration of whole blood, plasma, plasma fractions or platelets within 2 weeks prior to inclusion into study NOTE: Administration of packed red blood cells is not an exclusion criterion - Pre-existing progressive fatal disease with a life expectancy of less than 2 months - Known inhibitors to coagulation factors II, VII, IX, or X; or hereditary protein C or protein S deficiency; or heparin-induced, type II thrombocytopenia - Treatment with any other investigational medicinal product within 30 days prior to inclusion into the study, - Presence or history of hypersensitivity to components of the study medication - Pregnant or brest-feeding women - Prior inclusion in this study or any other CSL Behring sponsored Beriplex study, - For subjects with intracranial hemorrhage with: - Glasgow Coma Score <10 - Modified Rankin Score > 3 prior to ICH - Intracerebral hemorrhage - Epidural hematomas - Infratentorial hemorrhage - Subarachnoid hemorrhage (SAH) subjects with a Hunt and Hess Scale >2 - Subdural hematomas that: are judged to be an acute subdural hematoma (based on neurosurgeon review) or have a concurrent SAH or parenchymal contusion

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy variable will be the hemostatic efficacy with respect to the adequacy of preventing excessive bleeding during surgical or invasive intervention (the "procedure"). The primary efficacy endpoint will be assessed immediately after the surgery or procedure. the assessment covers the entire period from the start of infusion to immediately after the surgery or procedure. The assessment includes the clinical signs and symptoms of the subject, laboratory values such as INR and any additional hemostatic treatments. The efficacy of only the planned study treatment and intended procedure should be assessed. The adequacy of preparing the subject for the surgery or procedure and prevention of excessive bleeding during the surgery or procedure will be rated by data and safety monitoring board (DSMB) and treating physician as excellent, good, or poor/none, based on pre-specified definitions.
CO-PRIMARY EFFICACY VARIABLE The co-primary efficacy variable wil be the proportion of subjects who have a rapid decrease of the INR (i.e. INR ≤ 1.3) at 30 minutes after end of infusion.
