The purpose of this study is to evaluate efficacy, safety and tolerance of Beriplex® P/N
compared with plasma in regard to rapid reversal of coagulopathy induced by vitamin K
antagonists in subjects who require immediate correction of INR because of emergency
surgery.
Inclusion Criteria:
- Male and female subjects greater than or equal to 18 years,
- Subjects currently on oral VKA therapy,
- An urgent surgical procedure is required within 24 hours of the start of IMP,
- Due to the nature of the procedure, withdrawal of oral VKA therapy and infusion of
plasma are also indicated to reverse the VKA effect,
- INR greater than or equal to 2 within 3 hours before start of IMP,
- Informed consent has been obtained.
Exclusion Criteria:
- Subjects requiring urgent surgical procedures where according to the surgeon's
clinical judgment, an accurate estimate of blood loss is not possible (e.g., ruptured
aneurysm),
- Subjects for whom administration of intravenous vitamin K and vitamin K antagonists
withdrawal alone can adequately correct the subject's coagulopathy before initiation
of the urgent surgical procedure,
- Administration of intravenous vitamin K more than 3 hours or administration of oral
vitamin K more than 6 hours prior to infusion of IMP,
- Subjects in whom lowering INR within normal range may present an unacceptable risk
for a thromboembolic complication where the INR goal is to lower but not normalize
the INR because of risk of a procedure-associated stroke,
- Subjects, who despite medical management that includes close monitoring and
diuretics, may not, by investigator assessment, tolerate the total volume of IMP
required by the protocol,
- Expected need for additional non-study blood products before infusion of IMP (Note:
Administration of packed red blood cells is not an exclusion criterion),
- Expected need for platelet transfusions or desmopressin before Day 10,
- Acute trauma for which reversal of vitamin K antagonists alone would not be expected
to control or resolve an acute bleeding complication and/or control the acute
bleeding event,
- Unfractionated or low molecular weight heparin use within 24 hours before
randomization or potential need before completion of the procedure,
- History of thromboembolic event, myocardial infarction, unstable angina pectoris,
critical aortic stenosis, cerebral vascular accident, transient ischemic attack,
severe peripheral vascular disease, disseminated intravascular coagulation within 3
months of enrollment,
- Reversal of VKA therapy alone may not resolve the coagulopathy (eg, receiving a
potent anti-platelet agent, i.e., clopidogrel or prasugrel, or advanced liver
disease),
- Known history of antiphospholipid antibody syndrome or lupus anticoagulant
antibodies,
- Suspected or confirmed serious viral or bacterial infection, e.g., meningitis, or
sepsis at time of enrollment,
- Administration of whole blood, plasma, plasma fractions or platelets within 2 weeks
prior to inclusion into the 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 breast-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 (see Appendix 8)
- modified Rankin Score > 3 prior to ICH (see Appendix 9)
- 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)
- have a concurrent SAH or parenchymal contusion
