Outcome Measures

Primary Outcomes (2)

• Area Under the Curve From Time Zero to Extrapolated 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 - ∞).

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hours (hrs) post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2

• Maximum Observed Plasma Concentration (Cmax)

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2

Secondary Outcomes (12)

• Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2

• Time to Reach Maximum Observed Plasma Concentration (Tmax)

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2

• Plasma Decay Half-Life (t1/2)

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2

• Apparent Oral Clearance (CL/F)

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2

• Apparent Volume of Distribution (Vz/F)

  0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 1 and Day 0, 0 (pre-dose), 1, 2, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96 and 144 hrs post crizotinib dose in period 2
