This study will be an open-label, randomized, 2-period, 2-treatment, 2-sequence, cross-over single-dose study employing administration of two oral formulations of crizotinib (OLF and FC) in the fasted state to healthy adult subjects. Twenty-two (22) subjects will be enrolled to obtain at least 20 evaluable subjects who complete the study. Each subject will receive two treatments (A and B) with a washout period of at least 14 days between each treatment.

Area Under the Curve From Time Zero to Infinite Time [AUC (0 - ∞)]
AUC (0 - ∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞).
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hours (hrs) post crizotinib dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration (AUClast).
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose
Maximum Observed Plasma Concentration (Cmax)
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose
Plasma Terminal Half-Life (t1/2)
Plasma terminal half-life is the time measured for the plasma concentration to decrease by one half.
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose
Apparent Oral Clearance (CL/F)
Drug clearance (CL) is a quantitative measure of the rate at which a drug substance is removed from the plasma. Clearance obtained after oral dose (apparent oral clearance \[CL/F\]) is influenced by the fraction of the dose absorbed (F).
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose

Apparent Volume of Distribution (Vz/F)
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
Time frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose
