入选标准
- •All female participants, except if postmenopausal, must have a negative serum beta-human chorionic gonadotropin (beta hCG) pregnancy test at screening and a negative urine pregnancy test on Day 1 of each treatment period
- •A female participant must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for at least 1 month after the last study drug administration
- •A male participant, who is sexually active with a woman of childbearing potential and has not had a vasectomy, must agree to use an adequate contraception method as deemed appropriate by the investigator (example, vasectomy, double-barrier, partner using effective contraception) and to not donate sperm during the study and for 3 months after receiving the last dose of study drug
- •Must have a body mass index (body mass index [BMI]; weight kilogram per meter per height per square per meter square [kg/height^2 m^2]) between 18.0 and 30.0 kg/m^2 (inclusive) with a body weight not lower than 50 kilogram (kg)
- •Must have a blood pressure (after the participant is supine for 5 minutes) between 90 and 140 millimeters of Mercury (mmHg) systolic, inclusive, and no higher than 90 mmHg diastolic. Heart rate between 45 and 100 beats per minute (bpm), inclusive
排除标准
- •History of or current renal insufficiency (estimated glomerular filtration rate [eGFR] less than (<) 90 milliliter per minute per meter square (mL/min/1.73m^2) based on the Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] formula at screening only)
- •Clinically significant abnormal values for hematology, serum chemistry (including thyroid-stimulating hormone [TSH] at screening only) or urinalysis at screening or at admission to the study site, as deemed appropriate by the investigator. It is expected that laboratory values will generally be within the normal range for the laboratory, though minor deviations, which are not considered to be of clinical significance to the investigator, are acceptable
- •Clinically significant abnormal physical examination, vital signs, or 12-lead electrocardiogram (ECG) at screening or at admission to the study site as deemed appropriate by the investigator
- •Received a known inhibitor of Cytochrome (CY) P3A4, CYP3A4, CYP2C8, or P-glycoprotein (P-gp) activity within 14 days or a period less than 5 times the drugs' half-life; whichever is longer, before the first dose of the study drug is scheduled
- •Received a known inducer of CYP3A4 or CYP2C8 activity within 28 days before the first dose of the study drug is scheduled
