• Positive test for drugs of abuse (including alcohol) at Screening and prior to each dosing
• Unlikely to comply with the protocol requirements, instructions and study-related restrictions; example, uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study
• Participant is the Principal Investigator or any Sub investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the study
