Rapid vitamin K antagonist (VKA) reversal is required in patients experiencing major bleeding or requiring urgent surgery. Four-factor prothrombin complex concentrate (4F-PCC; Beriplex(®)/Kcentra(®)) was shown in two large randomized controlled, international phase 3b trials to be an effective alternative to plasma for urgent VKA reversal. In the present prospective, open-label, single-arm phase 3b trial, we evaluate the efficacy and safety of 4F-PCC in Japanese patients. Eleven patients [international normalized ratio (INR) ≥2] requiring rapid VKA reversal owing to major bleeding (n = 6) or before urgent surgical/invasive procedures (n = 5) were administered 4F-PCC dosed based on INR and weight...

BACKGROUND: PCC (Kcentra®) is an Food and Drug Administration (FDA)-approved 4-factor PCC used for the treatment of warfarin-related coagulopathy (WRC), but it has also been used off-label to treat non-WRC. Three-factor PCC in the form of coagulation factor IX human (Bebulin®) has also been used for WRC and off-label to treat non-WRC. It is unclear whether the use of 3- or 4-factor PCCs is effective for the treatment of non-WRC,. OBJECTIVE: Our aim is to characterize the use of 3- and 4-factor PCCs for patients identified with a non-WRC...

To report the impact of an inpatient anticoagulation stewardship program at a community hospital to promote optimal anticoagulant use. The anticoagulation team (ACT) stewardship program consists of two clinical pharmacists and hematologists to provide oversight of anticoagulants, high cost reversal agents including prothrombin complex concentrate (PCC, Kcentra™), and heparin-induced thrombocytopenia (HIT) management. Intervention data and number of charts reviewed were collected. Average cost avoidance data was applied to ACT interventions to estimate cost savings...

A 4-factor prothrombin complex concentrate (4F-PCC, Kcentra®) was recently approved in the United States for the reversal of vitamin K antagonist-associated major bleeding, but it is often used to reverse coagulopathy in patients with liver disease (LD). This single-center, retrospective study analyzed the efficacy and safety of 4F-PCC administered in patients with and without LD. Prothrombin time/International Normalized Ratio (PT/INR) reversal with 4F-PCC was attempted in 85 patients; LD was documented in 31 patients...

BACKGROUND All patients with a ventricular assist device (VAD) awaiting heart transplantation are anticoagulated with warfarin to prevent thromboembolism. The use of 4 factor prothrombin complex concentrate (PCC4, Kcentra®) for anticoagulation reversal prior to surgery may include benefits such as quicker reversal, longer duration of action, and a reduction in total volume of blood products used compared to other reversal practices. The study objective is to evaluate benefits of using an anticoagulation reversal protocol featuring PCC4, over standard of care in heart transplant patients requiring anticoagulation...

INTRODUCTION: Reversal of anticoagulation is required to mitigate the risk of intracranial bleeding before urgent neurosurgical procedures. New pharmacological agents, such as multifactor prothrombin complex concentrate (PCC; Kcentra), promise rapid efficacy but may raise the probability of thrombotic complications above vitamin K infusion or administration of fresh frozen plasma (FFP). In this study, we examined the rate of thrombotic complications in neurosurgical patients who received either PCC or FFP and Vitamin K before undergoing urgent surgery...

It was hypothesized that the four-factor prothrombin complex concentrate (4F-PCC) Kcentra 25 unit/kg would reverse impairment of thrombin generation in healthy volunteers dosed with apixaban to steady state. In this randomized, two-period crossover, assessor-blinded trial, 12 healthy subjects received 5 mg apixaban every 12 h. Three h after the fifth dose, four-factor prothrombin complex concentrate (4F-PCC) 25 unit/kg or saline were infused. Serial blood samples were assessed for thrombin generation using PPP-reagent and PPP-reagent low, anti-Xa, PT, and PTT assays...

BACKGROUND: Reversal of warfarin-induced coagulopathy after traumatic injury may be done exclusively with prothrombin complex concentrates (PCCs). No direct comparisons between different PCC regimens exist to guide clinical decision-making. Our institution has used 2 distinct PCC strategies for warfarin reversal; a 3-Factor PCC (Profilnine) combined with activated Factor VII (3F-PCC+rVIIa), and a 4-Factor PCC (Kcentra) given without additional factor supplementation. METHODS: Retrospective review of all PCC administrations to trauma patients with acute bleeding who were taking warfarin before injury...

OBJECTIVES: Clinicians often need to rapidly reverse vitamin K antagonists (VKAs) in the setting of major hemorrhage or urgent need for surgery. Little is known about the safety profile of the traditional reversal agent, plasma, or the newly approved agent, four-factor prothrombin complex concentrate (4F-PCC), in a randomized setting. This is an integrated analysis of safety data from two clinical trials that evaluated 4F-PCC versus plasma for the treatment of patients requiring rapid VKA reversal for acute major bleeding or prior to an urgent surgical/invasive procedure...

BACKGROUND: Transfusion of balanced ratios of plasma to platelets and red blood cells has been shown to reduce early death from exsanguination in trauma patients. Aside from hemostasis, recent work has shown that plasma reduces vascular endothelial permeability, inflammation, and organ edema after hemorrhagic shock (HS), all components of the endotheliopathy of trauma. We hypothesized that Kcentra could have protective effects on the endotheliopathy of trauma comparable with fresh frozen plasma (FFP)...

Prothrombin complex concentrates (PCCs) are indicated for urgent reversal of warfarin and used for reversal of novel oral anticoagulants, in patients with acute major bleeding or need for an urgent procedure. The research goal was to evaluate effectiveness and safety outcomes with PCC usage at our institution. A retrospective review of electronic medical records identified patients that received a PCC commercially available in the United States (KCentra(®) or Profilnine(®)) at twelve hospitals in a tertiary care health system from July 1, 2013 to April 30, 2014...

BACKGROUND: Bleeding is a serious complication after pediatric cardiopulmonary bypass (CPB) that is associated with an increase in perioperative morbidity and mortality. Four-factor prothrombin complex concentrates (4F-PCCs) have been used off-label to supplement transfusion protocols for bleeding after CPB in adults; however, data on their use in neonates are limited. In this study, we hypothesized that 4F-PCCs administered ex vivo to neonatal plasma after CPB will increase thrombin generation...

BACKGROUND: As the population ages, more trauma patients are admitted with coagulopathy. Fresh frozen plasma is effective in reversing coagulopathy caused by warfarin; however, it is not appropriate for all patients. Prothrombin complex concentrates (PCCs) are an alternative for patients who require emergent reversal, minimal-volume administration and who have a supratherapeutic international normalized ratio (INR). A four-factor PCC initially approved in Europe is now available in the United States...

BACKGROUND: Apixaban is a direct factor Xa inhibitor approved for the treatment and prevention of thromboembolic disease. There is a lack of data regarding its reversal in cases of acute bleeding or prior to emergency surgery that needs addressing. OBJECTIVES: This study assessed whether a four-factor prothrombin complex concentrate (4F-PCC; Beriplex(®) /Kcentra(®) , CSL Behring) can effectively reverse apixaban-associated bleeding in an in vivo rabbit model and evaluated the correlations between in vivo hemostasis and in vitro coagulation parameters...

BACKGROUND: Plasma is commonly used for vitamin K antagonist (VKA) reversal, but observational studies suggest that it is associated with transfusion-related adverse reactions (e.g., volume overload). However, this issue has not previously been addressed in a randomized controlled trial (RCT). STUDY DESIGN AND METHODS: Factors associated with volume overload were examined using data from two Phase IIIb RCTs comparing plasma with four-factor prothrombin complex concentrate (4F-PCC, Beriplex/Kcentra, CSL Behring) for urgent VKA reversal...
