The purpose of this study is to evaluate efficacy, safety and tolerance of Beriplex® P/N (Kcentra) compared with plasma in regard to rapid reversal of coagulopathy induced by vitamin K antagonists in subjects who require immediate correction of international normalized ratio (INR) because of emergency surgery.

Percentage of Participants Achieving Hemostatic Efficacy During Surgery
Hemostatic efficacy was rated as excellent, good, or poor/none, based on prespecified definitions. Hemostatic efficacy was the binary endpoint of effective or non-effective hemostasis, where 'effective' was a hemostatic efficacy rating of "excellent" or "good," and 'non-effective' was a hemostatic efficacy rating of "poor/none".
Time frame: From the start of infusion until the end of surgery
Percentage of Participants Who Had a Rapid Decrease of the INR
A rapid decrease of the INR was defined as an INR ≤ 1.3 at 30 minutes after the end of infusion. The INR is a standard way to describe the time it takes for blood to clot; an INR range of 0.8 to 1.2 is considered normal for a healthy person who is not using oral anticoagulant therapy.
Time frame: 30 minutes after the end of infusion
Plasma Levels of Factors II, VII, IX, and X, Protein C, and Protein S
Plasma levels are presented as the percentage of normal at pre-infusion and 30 min and 24 h after the start of infusion. The plasma level assay results are reported as a potency relative to a standard, where 100% is considered to be normal.
Time frame: From pre-infusion until 24 h after the start of infusion
Transfusion of Packed Red Blood Cells (PRBCs) or Whole Blood
The total units of transfused PRBCs or whole blood
Time frame: From the start of surgery until 24 h after the start of surgery
Percentage of Participants With INR Correction at Various Times After the Start of Infusion
The time taken from the start of infusion to INR correction (defined as an INR ≤ 1.3) was recorded. The percentage of participants with INR correction was calculated at 0.5, 1, 3, 6, 12, and 24 h after the start of infusion.
Time frame: From the start of infusion until INR correction; calculated at 0.5, 1, 3, 6, 12, and 24 h after the start of infusion
Percentage of Participants Who Received Red Blood Cells
Red blood cells were PRBCs and whole blood
Time frame: From the start of surgery until 24 h after the start of surgery
Overall Treatment-emergent Adverse Events (TEAEs)
Number of participants with TEAEs. TEAEs were defined as adverse events that developed or worsened following exposure to investigational medicinal product. Treatment-related TEAEs were events whose relationship to study treatment was related, probably related, or possibly related in the opinion of the investigator. Treatment emergent adverse events with missing relationship were considered related to treatment. Serious TEAEs were treatment-emergent serious adverse events (SAEs).
Time frame: From the start of infusion up to the allowed time window of the Day 10 visit for non-serious AEs and from the start of infusion up to the allowed time window of the Day 45 visit for SAEs
