• Surgically sterile (ie, bilateral tubal ligation or removal of both ovaries and/or uterus at least 6 mo prior to dosing)
• Naturally postmenopausal (spontaneous cessation of menses) for at least 24 consecutive mo prior to dosing, with a follicle stimulating hormone (FSH) level at Screening of ≥ 40 mIU/mL
• Non-lactating
• Male subjects must agree to contraception (condom with spermicide) in addition to having their female partner (if of childbearing potential) use another form of contraception (eg, an intrauterine device, diaphragm with spermicide, oral contraceptive, injectables, or subdermal hormonal implant) from the first dose until 12 wk following last administration. Also, male subjects must not donate sperm during the study and afterwards for a period of 12 wk.
• Provided written informed consent prior to participating in the study. Able to understand and willing to comply with all the study requirements, and willing to allow the collection of all blood and urine specimens.
• Negative urine test for drugs of abuse (opiates, benzodiazepines, amphetamines, cannabinoids, cocaine, barbiturates, phencyclidine), cotinine, and alcohol at Screening and During Enrollment on Day -1.
• Willingness to abstain from grapefruit/grapefruit juice and Seville oranges 10 d before the first dose of study drug on Day 1 until the end of the study on Day 31.
• Willingness to refrain from consuming food or beverages containing caffeine/xanthine and alcohol 24 h prior to Enrollment on Day -1 until the end of the study on Day 31.

You may not qualify if…

• History or current evidence of clinically significant cardiac, hepatic, renal, pulmonary, endocrine/metabolic, neurologic, infectious, gastrointestinal (ie, any condition which may affect drug absorption), hematologic, or oncologic disease.
• Laboratory results (serum chemistry, hematology, and urinalysis) outside of the normal range and considered clinically significant in the opinion of the PI. Liver function (AST, ALT, bilirubin) test results must be below the ULN at Screening and during Enrollment on Day -1.
• A QTcF interval duration > 450 msec at Screening.
• Participation in a previous DS-8500a study, or dosing with itraconazole, within 6 mo prior to the first dose.
• Known sensitivity to product components of DS-8500a and/or itraconazole.
• Current participation in another investigational study or prior participation in an investigational study within the past 30 d prior to the first dose.
