• Participants with no clinically significant abnormal screening results in the opinion of the investigator;
• All screening laboratory parameters (chemistry, hematology, coagulation, urinalysis) within normal limits or considered not clinically significant in the opinion of the investigator. If necessary, in the investigator's opinion, screening labs may be repeated once to confirm the results if error is suspected.
• Women of childbearing potential (WOCBP) must have a negative blood or urine pregnancy test within 24 hours prior to the start of investigational product and must not be breastfeeding, lactating or planning pregnancy during the study period. WOCBP must agree to use an acceptable form of contraception during the treatment period and for at least 30 days after the last dose of investigational product.
• A male subject with a female partner of childbearing potential is eligible to participate if he agrees to use acceptable contraception during the treatment period and for at least 90 days after the last dose of study treatment and refrains from donating sperm during this period;
• Agree to comply with study-specified diet and consume the high-fat breakfast in its entirety (food effect cohort) while confined in the study site;

• Any surgical procedure within 3 months prior to Day -1, that may interfere with the performance in the study in the judgment of the investigator;
• History or presence of cardiac abnormalities or congenital long QT syndrome;

• Any dietary restriction, intolerance, or food allergy that would prohibit the consumption of a high fat breakfast (food effect cohort only);
