The purpose of this study is to assess the relative bioavailability (the extent to which a drug or other substance becomes available to the body) of ibrutinib in healthy adults following single oral dose administration of suspension and sprinkle formulations under fed and fasted conditions compared with capsules under fasted conditions.
This is an open-label (all people know the identity of the intervention), randomized (study medication assigned to participants by chance), 3- or 4-way crossover (participants may receive different interventions sequentially during the trial), and single-center study of ibrutinib. The duration of study will be approximately 67 to 83 days per participant. The study consists of 3 parts: Screening (28 days before study commences on Day 1); Open-label Treatment (consists of 6 treatments, either Ibrutinib capsule or suspension or sprinkle capsule granules under fed or fasted condition), in subsequent 3 periods for Group 1 and 4 periods for Group 2, each separated with washout period of 7 (plus \[+\] / minus \[-\] 2) days; and follow up Phase (up to 10 + / - 2 days after last study drug administration). All the eligible participants will be randomly assigned to 1 of the 6 (Group 1) or 4 (Group 2) treatment sequences. In fasted conditions, study drug will be administered following a 10-hour overnight fast. In fed conditions, participants will also fast from food for 10 hours, but will consume a high fat breakfast within a 30-minute period. Study drug will be administered 2 hours after the breakfast. Participants will not be allowed to have food until 4 hours of drug administration. Blood samples will be collected for evaluation of pharmacokinetics at pre-dose and post-dose of study treatment. Relative bioavailability of Ibrutinib will be evaluated primarily. Participants' safety will be monitored throughout the study.

Maximum Plasma Concentration (Cmax) of Ibrutinib
The Cmax is the maximum observed plasma concentration of Ibrutinib.

Time to Reach the Maximum Plasma Concentration (Tmax) of Ibrutinib
The Tmax is the time to reach the maximum observed plasma concentration of Ibrutinib.
Time frame: Pre-dose; 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose on Day 1 of each period
Area Under the Plasma Concentration-Time Curve From 0 to 24 Hours (AUC[0-24]) Post Dose of Ibrutinib
The AUC (0-24hrs) is the area under the plasma Ibrutinib concentration-time curve from 0 to 24 hours post dosing.
Time frame: Pre-dose; 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose on Day 1 of each period
Area Under the Plasma Concentration-Time Curve From Time 0 to Time of the Last Observed Quantifiable Concentration (AUC [0-last]) of Ibrutinib
The AUC (0-last) is the area under the plasma Ibrutinib concentration-time curve from time 0 to time of the last observed quantifiable concentration (C\[last\]).
Time frame: Pre-dose; 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose on Day 1 of each period
Area Under the Plasma Concentration-Time Curve From 0 to Infinite Time (AUC[0-infinity]) Post Dose of Ibrutinib
The AUC (0-infinity) is the area under the plasma Ibrutinib concentration-time curve from time 0 to infinite time, calculated as the sum of AUC (0-last) and C(last)/lambda(z), in which AUC(0-last) is area under the plasma Ibrutinib concentration-time curve from time zero to time of the last quantifiable concentration, C(last) is the last observed quantifiable concentration and lambda(z) is elimination rate constant.
Time frame: Pre-dose; 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose on Day 1 of each period

Participants will receive Ibrutinib 560 mg sprinkle capsule granules as Treatment D under fasted conditions in one of the treatment periods.
Participants will receive Ibrutinib 560 mg sprinkle capsule granules as Treatment E under fed (high-fat) conditions in one of the treatment periods.
Participants will receive Ibrutinib 560 mg sprinkle capsule granules suspended in water as Treatment F under fasted conditions in one of the treatment periods.
Percentage of Area Under the Plasma Concentration-Time Curve Obtained by Extrapolation (%AUC[infinity,ex])
The %AUC(infinity,ex) is calculated by dividing the difference of AUC(0-infinity) and AUC(0-last) by AUC(0-infinity) and then multiplying by 100, (AUC\[0-infinity\] - AUC\[0-last\])\*100/AUC\[0-infinity\].
