The purpose of this study is to determine whether the bioavailability of apixaban crushed tablets suspended in water or mixed with applesauce is similar to the bioavailability of apixaban whole tablets administered orally.
This study will investigate the bioavailability of apixaban administered as crushed tablets suspended in water and as crushed tablets mixed with applesauce compared with that of whole tablets. The study results may allow enhancement of the apixaban label to include alternative methods of apixaban administration, which may be of benefit to patients who have difficulty swallowing.

Adjusted Geometric Mean of Maximum Observed Plasma Concentration (Cmax) of Apixaban
Maximum observed plasma concentration (Cmax) measured in nanograms per milliliter (ng/mL)
Time frame: Days 1, 5, and 9 predose and 0.5, 1, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 60 and 72 hours post dose
Adjusted Geometric Mean of Area Under the Plasma Concentration-time Curve (AUC) From Time Zero Extrapolated to Infinite Time [AUC(INF)] of Apixaban
Area Under the Plasma Concentration-time Curve (AUC) From Time of Zero Extrapolated to Infinite Time (INF) \[AUC (INF)\] is measured as nanograms multiplied by hours per milliliter (ng\*h/mL)
Time frame: Days 1, 5, and 9 predose and 0.5, 1, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 60, and 72 hours post dose
Adjusted Geometric Mean of Area Under the Plasma Concentration-time Curve (AUC) From Time Zero to the Time of the Last Quantifiable Concentration [AUC(0-T)] of Apixaban
Area Under the Plasma Concentration-time Curve (AUC) From Time Zero to the Last Quantifiable Concentration \[AUC (0-T)\] is measured as nanograms multiplied by hours per milliliter (ng\*h/mL)
Time frame: Days 1, 5, and 9 predose and 0.5, 1, 2, 3, 4, 5, 6, 9, 12, 24, 36, 48, 60, and 72 hours post dose
Number of Participants With Serious Adverse Events, Death, or Discontinuation Due to Adverse Events by Study Completion
Adverse Event (AE) = any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. Serious Adverse Event (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.
Time frame: Randomization to May 2014; approximately 6 weeks

Time of Maximum Observed Plasma Concentration (Tmax) of Apixaban
Time of maximum observed plasma concentration (Tmax) measured in hours (h)
Time frame: Days 1, 5 and 9 pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 9, 12 24, 36, 48, 60 and 72 hrs post dose
Terminal Plasma Half-life (T-HALF) of Apixaban
Terminal plasma half-life (T-HALF) was derived from plasma concentration versus time data. T-HALF was the time required for one half of the total amount of administered drug to be eliminated from the body.
Time frame: Days 1, 5 and 9 pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 9, 12 24, 36, 48, 60 and 72 hrs post dose
Relative Bioavailability (Frel) of Apixaban
Frel is calculated using the treatment ratio of AUC(INF) where the denominator is the AUC(INF) of the reference therapy, 10mg of Apixaban (whole tablet).
Time frame: Days 1, 5 and 9 pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 9, 12 24, 36, 48, 60 and 72 hrs post dose
