• Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
• Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests and other study procedures.

You may not qualify if…

• Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, 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 test.
• Subjects who currently smoke.
• History of regular alcohol consumption exceeding 7 drinks/week for female subjects or 14 drinks/week for male subjects (1 drink = 5 ounces [150 mL] of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) within 6 months before screening.
• Subjects with history of known sensitivity to esomeprazole or substituted benzimidazoles.
• Treatment with an investigational drug within 30 days or 5 half-lives preceding the first dose of study drug.
• Screening supine BP greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic), following at least 5 minutes of supine rest.
• Screening supine 12-lead triplicate ECG demonstrating a corrected time from the beginning of the Q wave to the end of the T wave corresponding to electrical systole (QTc) interval >450 msec or a QRS complex >120 msec.
• Subjects with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat test, if deemed necessary:
• Aspartate aminotransferase (AST) or ALT level greater than or equal to 1.5 × upper limit of normal (ULN);
• Total bilirubin (TBili) level greater than or equal to 1.5 × ULN; subjects with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is less than or equal to ULN.
• Male subjects who are unwilling or unable to use 2 highly effective methods of contraception as outlined in this protocol for the duration of the study and for at least 90 days after the last dose of investigational product.
• 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 IP.
• Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.
• History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody (HepBcAb), or hepatitis C antibody (HCVAb).
• Unwilling or unable to comply with the criteria in the Lifestyle Requirements section of this protocol.
• Subjects who are investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or subjects who are Pfizer employees, including their family members, directly involved in the conduct of the study.
• Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or crizotinib cMS and/or esomeprazole 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.
