13. History of a minimum of 1 bowel movement per day Exclusion criteria

1. Subject has a history of illicit drug abuse in the past year or displays current evidence of such abuse in the opinion of the Investigator.
2. Subject has positive findings on urine drug screen (including cotinine).
3. Subject is positive for human immunodeficiency virus (HIV), hepatitis B and/or hepatitis C on Screening assessments.
4. Subject has a QTcF \>450 msec at screening (confirmed by repeat).
5. Subject has a female partner who is either pregnant, nursing, or planning to become pregnant during the study or within 90 days after the last dose of the study drug, or unwilling to follow the contraception requirements.
6. Subject has a clinically significant acute illness within 1 week of CRU admission, or symptoms of active illness at check-in, at discretion of the Investigator (or designee).
7. Subject has a hypersensitivity or allergy to napabucasin or the ingredients of napabucasin, or other clinically significant allergies in the opinion of the Investigator.
8. Subject has donated plasma within 7 days of drug administration.
9. Subject has donated 1 or more pints of blood (or equivalent blood loss) within 30 days prior to drug administration.
10. Subject has a history of chronic Gastroesophageal reflux disease (GERD) or has used omeprazole or other proton pump inhibitors within 3 months of Screening.
11. Subject has congenital non-hemolytic hyperbilirubinemia \[e.g., Gilbert's syndrome\].
12. Subject has any condition possibly affecting drug absorption (e.g., gastrectomy, cholecystectomy, or other gastrointestinal tract surgery, except appendectomy).
13. Subject has participated in an investigational drug study within 30 days or 5 half-lives (whichever is longer) of exposure to another investigational medication prior to CRU admission.
14. Subject is an employee of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, or a family member of the employees or the Investigator.
15. Subjects with exposure to significant diagnostic or therapeutic radiation (e.g., serial Xray, computed tomography scan, barium meal) or employment in a job requiring radiation exposure monitoring within 12 months prior to check-in.
16. Subjects who have participated in a radiolabeled drug study where exposures are known to the Investigator within the previous 4 months prior to admission to the clinic for this study or participated in a radiolabeled drug study where exposures are not known to the Investigator within the previous 6 months prior to admission to the clinic for this study.
