Adjusted Geometric Mean Maximum Observed Plasma Concentration (Cmax) of Apixaban

Samples of plasma from participants were obtained at the following times: 0 hour (h) and post dose at 0.25h, 0.50h, 1h, 2h, 3h, 4h, 5h, 6h, 9h, 12h, 24h, 36h, 48h, 60h, and 72h. Apixaban was assayed using a validated Liquid chromatography tandem mass spectrometry (LC-MS/MS) method during the period of known analyte stability. Maximum observed plasma concentration (Cmax) was measured in nanograms per milliliter (ng/mL).

Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Discontinuation Due to AEs, Death

AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization.

Median Time of Maximum Observed Plasma Concentration (Tmax) of Apixaban

Samples of plasma from participants were obtained at the following times: 0 hour (h), 0.25h, 0.50h, 1h, 2h, 3h, 4h, 5h, 6h, 9h, 12h, 24h, 36h, 48h, 60h, and 72h, relative to the single dose on Day 1 in each cross over period. Apixaban was assayed using a validated LC-MS/MS method during the period of known analyte stability. Maximum observed plasma concentration (Tmax) was measured in hours (h).

Adjusted Geometric Mean Area Under the Plasma Concentration-Time Curve From Time Zero to the Time of Last Quantifiable Plasma Concentration, AUC(0-T), of Apixaban

Samples of plasma from participants were obtained at the following times: 0 h, 0.25h, 0.50h, 1h, 2h, 3h, 4h, 5h, 6h, 9h, 12h, 24h, 36h, 48h, 60h, and 72h, relative to the single dose on Day 1 in each cross over period. Apixaban was assayed using a validated LC-MS/MS method during the period of known analyte stability. AUC(0-T) was measured in nanograms*hours per milliliter (ng*h/mL).

Adjusted Geometric Mean Area Under the Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinite Time, AUC(INF), of Apixaban

Samples of plasma from participants were obtained at the following times: 0 h, 0.25h, 0.50h, 1h, 2h, 3h, 4h, 5h, 6h, 9h, 12h, 24h, 36h, 48h, 60h, and 72h, relative to the single dose on Day 1 in each cross over period. Apixaban was assayed using a validated LC-MS/MS method during the period of known analyte stability. AUC(0-INF) was measured in ng*h/mL.

Mean Plasma Elimination Half-Life (T-HALF) of Apixaban

Samples of plasma from participants were obtained at the following times: 0 h, 0.25h, 0.50h, 1h, 2h, 3h, 4h, 5h, 6h, 9h, 12h, 24h, 36h, 48h, 60h, and 72h, relative to the single dose on Day 1 in each cross over period. Apixaban was assayed using a validated LC-MS/MS method during the period of known analyte stability. T-HALF was measured in hours (h).

Number of Participants With Clinically Significant Electrocardiogram, Vital Sign, or Physical Examination Findings

12-lead electrocardiograms (ECGs) and Vital Signs were performed at Screening, and Day 1 of Periods 1, 2 and 3 (pre-dose and prior to NGT placement, if done). Vital signs and ECGs were also performed on Day 4 of Period 3, prior to discharge from the study. Vital signs included body temperature, respiratory rate, seated blood pressure and heart rate. Blood pressure and heart rate were measured after the participant had been seated quietly for at least 5 minutes. Participants had physical examinations on Period 1, Day 1 (pre-dose) and Day 4 of Period 3, prior to study discharge.

Number of Participants With Marked Abnormality in Hematology, Chemistry and Urinalysis Laboratory Tests

Participants were required to fast for at least 10 hours prior to the collection of specimens for clinical laboratory tests. Tests were performed at Screening, Day -1, and Day 4 of each period 1 - 3. Leukocyte criteria: Lower limits of normal (LLN), upper limits of normal (ULN), pre-treatment (preRX). Low Leukocytes: if value < 0.9*LLN, or if preRX < LLN then use < 0.85* preRX. High lymphocytes: if value > 7.500 10^3 cells/ µL. Low neutrophils plus bands: if value <= 1.500 10^3 cells/µL. High creatine kinase: if value > 1.5* ULN. Blood in urine: if value >= 2 plus, or if preRX >= 1 plus then use >= 2*preRX.
