What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Plasma Concentration (Cmax) of Ibrutinib | The Cmax is the maximum observed plasma concentration. | Day 1 (Pre-dose) up to Day 3 | 
| Time to reach maximum concentration (tmax) of Ibrutinib | The Tmax is defined as actual sampling time to reach maximum observed analyte concentration. | Day 1 (Pre-dose) up to Day 3 | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-last]) of Ibrutinib | The AUC (0-last) is the area under the plasma concentration-time curve from time zero to last quantifiable time. | Day 1 (Pre-dose) up to Day 3 | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity]) of Ibrutinib | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. | Day 1 (Pre-dose) up to Day 3 | 
| Elimination Rate Constant (Lambda[z]) of Ibrutinib | Lambda(z) is first-order elimination rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve. | Day 1 (Pre-dose) up to Day 3 | 
| Terminal Half-Life (t[1/2]) of Ibrutinib | The elimination half-life (t1/2) is the time measured for the plasma concentration to decrease by 1 half to its original concentration. It is associated with the terminal slope of the semi logarithmic drug concentration-time curve, and is calculated as 0.693/lambda(z). | Day 1 (Pre-dose) up to Day 3 | 
| Maximum Plasma Concentration (Cmax) of IMBRUVICA | The Cmax is the maximum observed plasma concentration. | Day 1 (Pre-dose) up to Day 3 | 
| Time to reach maximum concentration (tmax) of IMBRUVICA | The Tmax is defined as actual sampling time to reach maximum observed analyte concentration. | Day 1 (Pre-dose) up to Day 3 |
