1.  Primary:   Area Under the Curve From Time Zero to Infinite Time [AUC (0 - ∞)]   [ 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 ]
  Hide Outcome Measure 1

Measure Type Primary
Measure Title Area Under the Curve From Time Zero to Infinite Time [AUC (0 - ∞)]
Measure Description 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  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Pharmacokinetic (PK) parameter analysis population included all participants randomized and treated who had at least 1 of the PK parameters of primary interest in at least 1 treatment period.

Reporting Groups
  Description
Crizotinib 250 mg FC Single oral dose of crizotinib 250 mg FC [Reference] in either first intervention period or second intervention period.
Crizotinib 250 mg OLF Single oral dose of crizotinib 250 mg OLF [Test] in either first intervention period or second intervention period.

Ratio of Adjusted Means [2] 99.58
90% Confidence Interval ( 91.08 to 108.87 )
[1] Additional details about the analysis, such as null hypothesis and power calculation:
  Natural log transformed AUC (0 - ∞) of crizotinib was analyzed using a mixed effect model with sequence, period and treatment as a fixed effects and participant within sequence as a random effect. The adjusted mean differences and 90% confidence intervals (CIs) for the differences were exponentiated to provide estimates of the ratio of adjusted geometric means (Test/Reference) and 90% CIs for the ratios. This was an estimation study and there was no formal statistical hypothesis.
