Beriplex

A 45-year-old man receiving warfarin treatment suffered from an intracerebral hemorrhage. Four-factor prothrombin complex concentrate (PCC) was administered to correct coagulopathy. However, bilateral renal infarcts and a cerebral infarct developed on day 5 and 7, respectively after PCC administration. Although the occurrence of PCC-related thromboembolism is low, health care practitioners should closely follow-up the symptoms and signs of thrombosis after PCC administration.

Although new oral anticoagulants (NOACs) represent an advance in anticoagulant therapy over vitamin K antagonists (VKAs), they nevertheless have a low, but significant risk for bleeding complications. Reversal agents for VKAs, such as prothrombin complex concentrates (PCCs), are currently being evaluated in preclinical studies for NOAC reversal. This article reviews the preclinical data for the most extensively studied PCC for NOAC reversal, Beriplex, a 4-factor PCC. The results from the Beriplex studies are also compared with those obtained with other reversal agents, including different nonactivated PCCs, activated PCCs, and recombinant activated factor VII...

INTRODUCTION: In vivo animal data have shown prothrombin complex concentrate (PCC) to be effective in preventing bleeding induced by excessive plasma levels of the direct thrombin inhibitor dabigatran. This animal model study was designed to determine the risk of thrombosis associated with administration of a PCC (Beriplex P/N) to reverse dabigatran-induced bleeding. MATERIALS AND METHODS: Anesthetized rabbits were treated with initial 0, 75, 200 or 450 μg kg(-1) dabigatran boluses followed by continuous infusions to maintain elevated plasma dabigatran levels...

BACKGROUND: Four-factor prothrombin complex concentrates (PCCs), which contain factor II, FVII, FIX, and FX, have shown the potential to reverse the anticoagulant effect of rivaroxaban in healthy volunteers. The purpose of this study was to determine whether a three-factor PCC, which contains little FVII, has a similar effect. METHODS AND RESULTS: We performed an open-label, single-center, parallel-group study comparing the effect of a three-factor PCC (Profilnine SD) with that of a four-factor PCC (Beriplex P/N) on the pharmacodynamics of rivaroxaban in 35 healthy volunteers...

BACKGROUND: Dabigatran is a potent oral anticoagulant. Like any anticoagulant, there is an increased risk of bleeding associated with its use, and reversal may be needed in cases of severe bleeding. METHODS: In this study, six coagulation factor concentrates (CFCs) were tested for their ability to reduce bleeding induced by oral dabigatran etexilate (30 mg/kg) in a rat-tail bleeding model (n = 5 to 8 per group): three-factor (Profilnine [Grifols Biologicals Inc...

Rivaroxaban is an oral, direct factor Xa inhibitor for the management of thromboembolic disorders. Despite its short half-life, the ability to reverse rivaroxaban anticoagulation could be beneficial in life-threatening emergencies. The potential of prothrombin complex concentrate (PCC; Beriplex®), activated PCC (aPCC; FEIBA®) or recombinant activated factor VII (rFVIIa; NovoSeven®) to reverse rivaroxaban in rats and baboons was investigated. Anaesthetised rats pre-treated with intravenous rivaroxaban (2 mg/kg) received intravenous rFVIIa (100/400 μg/kg), PCC (25/50 U/kg) or aPCC (50/100 U/kg) after initiation of bleeding...

BACKGROUND: The rapid reversal of the effects of vitamin K antagonists is often required in cases of emergency surgery and life-threatening bleeding, or during bleeding associated with high morbidity and mortality such as intracranial haemorrhage. Increasingly, four-factor prothrombin complex concentrates (PCCs) containing high and well-balanced concentrations of vitamin K-dependent coagulation factors are recommended for emergency oral anticoagulation reversal. Both the safety and efficacy of such products are currently in focus, and their administration is now expanding into the critical care setting for the treatment of life-threatening bleeding and coagulopathy resulting either perioperatively or in cases of acute trauma...

BACKGROUND: One limitation of the direct thrombin inhibitor dabigatran is the lack of specific antidotes that allow acute bleeding events to be managed or urgent interventional procedures performed. Prothrombin complex concentrates (PCCs) have served as a standard treatment for the reversal of coumarin anticoagulation. OBJECTIVES: This study was designed to determine in an animal model whether a PCC (Beriplex P/N) can effectively reverse the effects of dabigatran...

Prothrombin complex concentrates (PCCs) and fresh-frozen plasma (FFP) have been clinically used for acute warfarin reversal. The recovery of prothrombin time (PT) or international normalised ratio (INR) is often reported as an endpoint, but haemostatic efficacies of PCCs and FFP may not be fully reflected in static clotting test in platelet-poor plasma. Using various in vitro assays, we compared the effects of two PCC preparations (3-factor PCC; Bebulin and 4-factor PCC; Beriplex) and FFP on warfarin reversal under static and flow conditions...

BACKGROUND: Oral anticoagulant therapy (OAT) is used to prevent/treat thromboembolism. Major bleeding is common in patients on OAT; eg, warfarin increases intracranial hemorrhage (ICH) risk. CASE: A 71-year-old male on warfarin (to reduce stroke risk) presented at Accident and Emergency Minor Injuries Unit with headache after reportedly sounding 'drunk'. On triage, the patient appeared lucid and well. However, International Normalized Ratio (INR) was 4.1. Head computed tomography (CT) indicated a large right-sided subdural hematoma...

INTRODUCTION: Uncontrolled haemorrhage is the leading cause of potentially reversible early in-hospital death following trauma. Approximately 25% of trauma patients arriving in the emergency department have evidence of early coagulopathy. It is vital that staff within the emergency department understand the basic pathophysiological consequences of massive blood loss in trauma and are familiar with when and how to administer blood and specific blood components in trauma resuscitation. METHODS: A structured questionnaire designed to test knowledge of the use of blood and blood components in trauma resuscitation was distributed to the emergency physicians attending a regional conference in the South West of England...

INTRODUCTION: Prothrombin complex concentrates are recommended for rapid reversal of vitamin K anticoagulants. As they normalize levels of vitamin K dependent clotting factors and re-establish hemostasis, they may also be used as adjunctive therapy in patients with major bleeding. The aim of this study was to retrospectively evaluate the efficacy of prothrombin complex concentrates in the surgical setting. METHODS: The case notes of 50 patients requiring urgent oral anticoagulation reversal (n = 12) or with severe perioperative coagulopathic bleeding (n = 38) who received an infusion of prothrombin complex concentrate (Beriplex P/N(R) 500) at the surgical department of the University of Munich Hospital, Germany were retrospectively reviewed...

INTRODUCTION: Fluid resuscitation after trauma often results in dilutional coagulopathy that may hinder control of bleeding and, once initial hemostasis has been secured, heighten risk of perioperative bleeding when further surgery is required. Since multiple coagulation factor deficiencies typically accompany fluid resuscitation, prothrombin complex concentrate (PCC) containing factors II, VII, IX and X may potentially offer greater hemostatic efficacy than coagulation factor monotherapy...

Prothrombin complex concentrate (PCC) infusion is preferred for emergency reversal of coumarin therapy. Rapid infusion can potentially save crucial time; however, the possible impact of high infusion speed on PCC safety and effectiveness has not been delineated. In a prospective multinational clinical trial with 43 patients receiving PCC (Beriplex P/N) for emergency reversal of coumarin therapy, infusion speeds were selected by the investigators. In a two-phase statistical analysis, the influence of baseline patient variables and dose on selected infusion speed was assessed...

Beriplex P/N, a prothrombin complex concentrate derived from pooled human plasma, contains the vitamin K-dependent coagulation factors II, VII, IX and X, and the vitamin K-dependent coagulation inhibition proteins C and S. Intravenous Beriplex P/N provided rapid and sustained normalization of elevated international normalized ratios and controlled bleeding in adult patients participating in several prospective, noncomparative clinical studies (n = 8-43), with these data supported by clinical experience during its use over more than a decade...

BACKGROUND: Warfarin reversal is a common clinical situation. This is commonly performed using vitamin K and, depending on the urgency, fresh frozen plasma (FFP), prothrombin complex concentrates (PCCs), or activated factor VII. Even though PCCs are widely used, the ideal dosing regimen is far from established. OBJECTIVES: To verify differences in warfarin reversal patterns using FFP, recombinant FVIIa (rFVIIa), and PCC; and to test the hypothesis that supratherapeutic International Normalized Ratios (INRs) might not correlate with thrombin generation (TG) and identify the ideal concentrations of PCC required to reverse various INR thresholds...

BACKGROUND: Severe FX deficiency is a rare disorder with a variable bleeding tendency but spontaneous life threatening haemorrhage can occur. Treatment for invasive procedures and spontaneous bleeding is with prothrombin complex concentrates (PCC). When used in large or repetitive doses these are associated with a thrombotic tendency. FX:C levels of 0.15 - 0.30 IU/ mL are thought to be haemostatic during surgery . There is only limited information on the outcome and management of pregnancy in severe FX deficiency...

INTRODUCTION: Major blood loss can often be life-threatening and is most commonly encountered in the settings of surgery and trauma. Patients receiving anticoagulant therapy are also at increased risk of bleeding. We investigated the use of a prothrombin complex concentrate (PCC; Beriplex P/N, CSL Behring, Marburg, Germany) to treat severe bleeding in a variety of settings: cardiac surgery, warfarin therapy and other surgery. METHODS: Thirty consecutive patients who had received PCC were identified from blood transfusion records...

AIMS: A number of prothrombin complex concentrates (PCCs) are commercially available but they differ in terms of composition. We performed a series of studies to compare the biochemical properties of seven PCCs. METHODS: The following products were investigated: Beriplex P/N, Octaplex, S-TIM 4, PPSB Solvent Detergent, Uman Complex DI, Kaskadil and Cofact. Assays were performed to investigate levels of coagulation factors and their inhibitors, activated coagulation factors and heparin...
