Cycle 2 Day 1- Twice daily dosing: pre-dose and 1, 2, 4, 6, 8, 12 hours post-dose; Once daily dosing: pre-dose and 1, 2, 4, 6, 8, 24 hours post-dose
Secondary	Unbound Maximum Observed Plasma Concentration (Cmax) of PF-06260182: Cycle 2 Day 1	Unbound Cmax of PF-06260182, (a metabolite of Crizotinib) is reported in this outcome measure.	Cycle 2 Day 1- Twice daily dosing: pre-dose and 1, 2, 4, 6, 8, 12 hours post-dose; Once daily dosing: pre-dose and 1, 2, 4, 6, 8, 24 hours post-dose
