- Females of childbearing potential.
- 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.

- Subject is the Investigator or sub-Investigator. research assistant, pharmacist, study coordinator, other staff, or a relative of study personnel directly involved with the conduct of the study.
- 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.
