Primary Outcome Measures:
  • 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 ] [ 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 - ∞).


Secondary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]
  • Area Under the Curve From Time Zero to Last Quantifiable 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 ] [ Designated as safety issue: No ]
    Area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration (AUClast).

  • 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 ] [ Designated as safety issue: No ]
  • Plasma Terminal Half-Life (t1/2) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
    Plasma terminal half-life is the time measured for the plasma concentration to decrease by one half.

  • Apparent Oral Clearance (CL/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 ] [ Designated as safety issue: No ]
    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).

  • Apparent Volume of Distribution (Vz/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 ] [ 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 plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

  • Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) for Crizotinib Metabolite (PF-06260182) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
    Area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration (AUClast) of Crizotinib metabolite (PF-06260182).

  • Area Under the Curve From Time Zero to Infinite Time [AUC (0 - ∞)] for Crizotinib Metabolite (PF-06260182) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ 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 - ∞) of crizotinib metabolite (PF-06260182).

  • Maximum Observed Plasma Concentration (Cmax) for Crizotinib Metabolite (PF-06260182) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax) for Crizotinib Metabolite (PF-06260182) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
  • Metabolite to Parent Ratio of Maximum Observed Plasma Concentration (MRCmax) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
    Metabolite (PF-06260182) to parent (crizotinib) molar ratio of maximum observed plasma concentration (MRCmax).

  • Metabolite to Parent Ratio of Area Under the Curve From Time Zero to Last Quantifiable Concentration (MRAUClast) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
    Molar ratio of metabolite to parent area under the plasma concentration time-curve from time zero (pre-dose) to the last measured concentration (MRAUClast).

  • Metabolite to Parent Ratio of Area Under the Curve From Time Zero to Infinite Time [MRAUC (0- ∞)] [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48, 72, 96 and 144 hrs post crizotinib dose ] [ Designated as safety issue: No ]
    Molar ratio of metabolite to parent area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0- ∞) [MRAUC (0- ∞)].

Criteria

Inclusion Criteria:

  • Healthy male and/or female subjects between the ages of 18 and 55 years, inclusive. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead ECG or clinical laboratory tests.
  • Body Mass Index (BMI) of 17.5 to 30.5 kg/m^2; and a total body weight >50 kg (110 lbs).

Exclusion Criteria:

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
  • Any condition possibly affecting drug absorption (eg, gastrectomy).
  • A positive urine drug screen.

  • Treatment with an investigational drug within 30 days (or as determined by the local requirement, whichever is longer) or 5 half-lives preceding the first dose of study medication.
  • 12-lead ECG demonstrating QTc >450 msec or a QRS interval >120 msec at screening. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three QTc or QRS values should be used to determine the subject's eligibility.
  • Pregnant or nursing females; females of childbearing potential, including those with tubal ligation.
  • Use of prescription or nonprescription drugs and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study medication. Herbal supplements and hormonal replacement therapy must be discontinued 28 days prior to the first dose of study medication. As an exception, acetaminophen/paracetamol may be used at doses of ≤1 g/day. Limited use of non-prescription medications that are not believed to affect subject safety or the overall results of the study may be permitted on a case-by-case basis following approval by the sponsor.
  • Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 56 days prior to dosing.
  • History of sensitivity to heparin or heparin-induced thrombocytopenia.
  • Unwilling or unable to comply with the Lifestyle Guidelines described in this protocol.
  • Subjects who are investigational site staff members or subjects who are Pfizer employees directly involved in the conduct of the trial.
  • Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
  • A positive serology for Hepatitis B or Hepatitis C.
  • Subjects who currently smoke.
