| Pharmacodynamic (PD) Parameter: Adjusted Mean Change in Endogenous Thrombin Potential (ETP) From Day 4 Pre-Infusion (PCC or Placebo) Baseline at Day 4, 30 Minutes Post Infusion of PCC or Placebo | Day 4 at 3 hours post apixaban dose and prior to infusion (Pre-infusion Baseline), Day 4 at 30 minutes post infusion (PCC or Placebo) | ETP was evaluated using a Thrombin Generation Assay (TGA), a validated automated ex vivo assay performed on platelet-poor plasma samples and based on the automated, calibrated thrombin generation method: thrombin formation was triggered with recombinant tissue factor and phospholipids. Thrombin concentration in each sample was calculated over time by measuring the cleavage of a fluorogenic substrate in the context of a paired calibration sample. Dedicated software (Thrombinoscope, Thrombinoscope B.V., Maastricht, The Netherlands) performed the calculations and derived ETP as area under the curve from the resulting thrombogram curve. Pre-infusion baseline= sample on Day 4, 3 hours post apixaban dose (just prior to IV infusion of PCC or placebo). Samples on Day 4 were obtained at 0 (pre-dose), 0.5, 1, 2, 3 hours post apixaban dose and at 0.5, 1, 2, 4, 6, 9, 21, 45, and 69 hours post infusion (PCC or Placebo) in each treatment period.

Outcome results
PD Parameter: Adjusted Mean Change in Endogenous Thrombin Potential (ETP) From Day 1 Pre-Dose Apixaban Baseline at Day 4, 30 Minutes Post Infusion of PCC or Placebo
ETP was evaluated using a Thrombin Generation Assay (TGA), a validated automated ex vivo assay performed on platelet-poor plasma samples and based on the automated, calibrated thrombin generation method: thrombin formation was triggered with recombinant tissue factor and phospholipids. Thrombin concentration in each sample was calculated over time by measuring the cleavage of a fluorogenic substrate in the context of a paired calibration sample. A dedicated software program (Thrombinoscope, Thrombinoscope B.V., Maastricht, The Netherlands) performed the calculations and derived ETP as area under the curve from the resulting thrombogram curve. Pre-dose Apixaban baseline was Day 1 pre-dose (0 hour). Samples on Day 4 were obtained at 0, 0.5, 1, 2, 3 hours post apixaban dose and at 0.5, 1, 2, 4, 6, 9, 21, 45, and 69 hours post infusion (PCC or Placebo) in each treatment period.
Time frame: Day 1 pre-dose apixaban (pre-apixaban Baseline), Day 4 at 30 minutes post infusion (PCC or Placebo)
Population: PD Population included all participants who received any study medication and had PD data available for at least the analysis-specified baseline and 30 minutes after the start of the study drug infusion. 1 participant who received a partial PCC dose (approximately 2 IU/kg) was excluded from this summary analysis.

Pharmacodynamic (PD) Parameter: Adjusted Mean Change in Endogenous Thrombin Potential (ETP) From Day 4 Pre-Infusion (PCC or Placebo) Baseline at Day 4, 30 Minutes Post Infusion of PCC or Placebo
ETP was evaluated using a Thrombin Generation Assay (TGA), a validated automated ex vivo assay performed on platelet-poor plasma samples and based on the automated, calibrated thrombin generation method: thrombin formation was triggered with recombinant tissue factor and phospholipids. Thrombin concentration in each sample was calculated over time by measuring the cleavage of a fluorogenic substrate in the context of a paired calibration sample. Dedicated software (Thrombinoscope, Thrombinoscope B.V., Maastricht, The Netherlands) performed the calculations and derived ETP as area under the curve from the resulting thrombogram curve. Pre-infusion baseline= sample on Day 4, 3 hours post apixaban dose (just prior to IV infusion of PCC or placebo). Samples on Day 4 were obtained at 0 (pre-dose), 0.5, 1, 2, 3 hours post apixaban dose and at 0.5, 1, 2, 4, 6, 9, 21, 45, and 69 hours post infusion (PCC or Placebo) in each treatment period. ETP was measured as nanomolar\*minute (nM\*min).
Time frame: Day 4 at 3 hours post apixaban dose and prior to infusion (Pre-infusion Baseline), Day 4 at 30 minutes post infusion (PCC or Placebo)
Population: PD Population included all participants who received any study medication and had PD data available for at least the analysis-specified baseline and 30 minutes after the start of the study drug infusion. 1 participant who received a partial PCC dose (approximately 2 IU/kg) was excluded from this summary analysis.

PD Parameter: Adjusted Mean Change in TGA Lag Time and TGA Time to Peak From Day 1 Pre-Dose Apixaban Baseline at Day 4, 30 Minutes Post Infusion of PCC or Placebo
TGA is a validated, automated ex vivo assay performed on platelet-poor plasma samples and based on the automated, calibrated thrombin generation method: thrombin formation was triggered with recombinant tissue factor and phospholipids and the concentration in each sample was calculated over time by measuring the cleavage of a fluorogenic substrate in the context of a paired calibration sample; dedicated software program was Thrombinoscope, B.V., Maastricht, The Netherlands. Baseline was Day 1, 0 hour pre-dose apixaban. Samples on Day 4 were obtained at 0, 0.5, 1, 2, 3 hours post apixaban dose and 0.5, 1, 2, 4, 6, 9, 21, 45, and 69 hours post infusion (PCC or Placebo) in each treatment period.

PD Parameter: Adjusted Mean Change in TGA Peak Height From Day 1 Pre-Dose Apixaban Baseline at Day 4, 30 Minutes Post Infusion of PCC or Placebo
TGA is a validated, automated ex vivo assay performed on platelet-poor plasma samples and based on the automated, calibrated thrombin generation method: thrombin formation was triggered with recombinant tissue factor and phospholipids and the concentration in each sample was calculated over time by measuring the cleavage of a fluorogenic substrate in the context of a paired calibration sample; dedicated software program was Thrombinoscope, B.V., Maastricht, The Netherlands. Baseline was Day 1, 0 hour pre-dose apixaban. Samples on Day 4 were obtained at 0, 0.5, 1, 2, 3 hours post apixaban dose and 0.5, 1, 2, 4, 6, 9, 21, 45, and 69 hours post infusion (PCC or Placebo) in each treatment period. TGA Lag Time and Time to Peak parameters were measured in minutes.
Time frame: Day 1, pre-dose apixaban (Baseline), Day 4, 30 minutes post infusion.
Population: PD Population included all participants who received any study medication and had PD data available for at least the analysis-specified baseline and 30 minutes after the start of the study drug infusion. 1 participant who received a partial PCC dose (approximately 2 IU/kg) was excluded from this summary analysis.
