Primary Outcome Measures:
  • Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)] [ Time Frame: 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 ] [ Designated as safety issue: No ]
    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 - ∞).

    Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the body. Clearance obtained after oral dose CL/F is influenced by the fraction of the dose absorbed.

  • Apparent Volume of Distribution (Vz/F) [ Time Frame: 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 ] [ Designated as safety issue: No ]
    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 blood concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
