•No clinically significant findings on screening evaluations (clinical, laboratory [except lipids], and ECG).
•Ability to swallow and retain oral tablets.
•Willingness to avoid pregnancy or fathering children based on the criteria below.
•Male participants with reproductive potential must agree to take appropriate precautions to avoid fathering children, including refraining from donating sperm, from screening through 90 days (a spermatogenesis cycle) after the last dose of study drug. Permitted methods in preventing pregnancy should be communicated to the participants and their understanding confirmed.
•All female participants must have a negative pregnancy test at screening and a negative pregnancy test at check-in (Day -1) and must agree to take appropriate precautions to avoid pregnancy and refrain from donating oocytes from screening through 30 days (1 menstrual cycle) after the last dose of study drug. Permitted methods in preventing pregnancy should be communicated to the participants and their understanding confirmed.
•Female participants not considered to be of childbearing potential as defined in the protocol are eligible and must have a negative pregnancy test at screening and check-in.

排除标准

•High blood pressure (systolic blood pressure > 140 mm Hg or diastolic blood pressure > 90 mm Hg at screening, confirmed by repeat testing).
•Confirmed resting pulse (up to 3 measurements) < 40 bpm or > 100 bpm at screening for vital signs.
•History or presence of an abnormal ECG before initial dose administration.
•Presence or history of a malabsorption syndrome possibly affecting drug absorption (eg, Crohn disease or chronic pancreatitis).
•History of malignancy within 5 years of screening, with the exception of cured basal cell or squamous cell carcinoma of the skin, ductal carcinoma in situ, or Gleason 6 prostate cancer.
•History of other malignancy within 2 years of screening (with the exception of cured basal cell or squamous cell carcinoma of the skin, superficial bladder cancer, prostate intraepithelial neoplasm, carcinoma in situ of the cervix, or other noninvasive or indolent malignancy) or cancers from which the participant has been disease-free for < 1 year after treatment with curative intent.
•Current or recent (within 3 months of screening) clinically significant gastrointestinal disease or surgery (including cholecystectomy; excluding appendectomy and hernia repair) that could affect the absorption of study drug.
•Hemoglobin, WBC count, platelet count, or absolute neutrophil count less than the laboratory lower limit of normal at screening or at check-in, confirmed by repeat testing (up to twice).
•Hepatic transaminases (ALT and AST), ALP, or total bilirubin > 1.25 × the laboratory-defined ULN.
•Any major surgery within 4 weeks of screening.
