MeasureTime frameDescription
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 PlaceboDay 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. ETP was measured as nanomolar\*minute (nM\*min).

Participants received 10 mg apixaban BID on Days 1-3 and on Day 4 received a single dose of 10 mg apixaban followed 3 hours later by an IV infusion of 50 IU/kg prothrombin complex concentrate (PCC) (which was either Cofact or Beriplex P/N) or the participant received an IV infusion of placebo (saline solution). Participants were randomized on Day 1 to one of 6 treatment sequences (ABC, ACB, BAC, BCA, CAB and CBA).

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.

Comparison: The ETP change from pre-PCC baseline was analyzed using a mixed effect model that included treatment, sequence, and period as main effects. A hierarchical analysis was conducted with comparisons beginning with the primary endpoint and continuing through secondary endpoints (ETP; TGA lag time; TGA time to peak; TGA peak; TGA velocity index; PT; INR; aPTT; AXA).

Number of Participants With Out of Range Electrocardiogram (ECG) Intervals and Number of Participants With a Change From Baseline of Greater Than 30 Milliseconds in QT and QTcF

Single 12-lead ECGs were obtained at screening, Day -1 of Period 1, and Days 4 and 7 of each treatment period after the participant had been supine for at least 5 minutes. Pulse Rate (PR), Complex of Q, R, S waves (QRS), and contraction of ventricle between the beginning of the Q wave and end of the T wave (QT) were measured in milliseconds (msec). QT was corrected by the Fridericia method (QTcF) and measured in msec. Baseline was Day -1 of first treatment period. Crossover study: same participant with out of range ECG intervals could be reported in multiple arms.

Time frame: Day -1 first treatment period, Days 4 and 7 each treatment period

Population: Those participants who received any study medication and had available ECG data at baseline and Days 4 and 7 in each treatment period were analyzed.

PD Parameter: Adjusted Mean Change in Plasma Anti-Xa Activity From Day 4 Pre-Infusion (PCC or Placebo) Baseline at Day 4, 30 Minutes Post Infusion of PCC or Placebo

Anti-FXa activity was measured using a validated method at Esoterix Coagulation Laboratory (Englewood, CO) using the Diagnostica Stago Rotachrom (Registered) Heparin assay on a STA-Compact (Registered) analyzer. 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. The results of this chromogenic assay were reported in low molecular weight heparin (LMWH) activity units per milliliter (U/mL), which are equivalent to international units per milliliter (IU/mL) with assay reportable range: 0.1 to 18.4 IU/mL.

Time frame: Day 4 at 3 hours post apixaban dose and prior to infusion (Pre-infusion Baseline), Day 4 at 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.

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.
