6. Subjects with history of known sensitivity to esomeprazole or substituted

7. Treatment with an investigational drug within 30 days or 5 half-lives preceding the
first dose of study drug.

8. 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.

9. 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.

10. 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:

1. Aspartate aminotransferase (AST) or ALT level greater than or equal to 1.5 ×
upper limit of normal (ULN);

2. 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.

11. 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.

12. 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.

13. Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more
within 60 days prior to dosing.

14. 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).

15. Unwilling or unable to comply with the criteria in the Lifestyle Requirements section
of this protocol.

16. 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

directly involved in the conduct of the study.

17. 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.
