1.History of clinically significant central nervous system (e.g., seizures), cardiac, pulmonary, metabolic, renal, hepatic, or gastrointestinal conditions or history of any conditions that, in the opinion of the Investigator, may place the subject at an unacceptable risk as a participant in this trial, may interfere with the interpretation of safety and/or tolerability data obtained in the trial, or may interfere with the absorption, distribution, metabolism, or excretion of the study drugs
2.Participation in a clinical trial or receipt of an investigational medication or a new chemical entity within 30 days or 5 half-lives, or twice the duration of the biological effect of the medication (whichever is longer) prior to the first dose of study medication
