6. Blood pressure (after at least 2 minutes of rest) between 90 and 140 mmHg systolic, inclusive, and no higher than 90 mmHg diastolic.

7. A 12-lead ECG consistent with normal cardiac conduction and function, including:

- Sinus rhythm

- Pulse rate between 40 and 100 beats per minute (bpm)

- QTc interval =450 milliseconds (QT interval corrected using Fridericia correction method [QTcF]

- QRS interval of <120 milliseconds

9. Must have a negative alcohol test at Screening and Day -2

10. Must have adequate venous access in both arms, in the opinion of the Investigator

11. Has a screening serum total 25-hydroxyvitamin D level between 10 and 40 ng/mL, inclusive

12. If male, must agree to use contraception as detailed in Appendix 5 of this protocol during the treatment period and for at least 3 months after the last dose of study treatment and refrain from donating sperm during this period

13. If female, be sterile (ie, at least 1 month post-surgical sterilization, confirmed nonsurgical sterilization or at least 6 months post-menopausal [as determined by follicle stimulating hormone (FSH) / estradiol testing]); or who are of childbearing potential but are abstinent, have a surgically sterile partner (ie, at least 6 months postvasectomy), or are using a copper intrauterine device or a combination of at least 2 acceptable barrier methods such as condom + intravaginal spermicide, diaphragm + intravaginal spermicide, or cervical cap + intravaginal spermicide. Contraceptive medications (oral or by other routes) containing steroid hormones are not allowed. Women of childbearing potential must not be lactating and must have a negative pregnancy test at screening and Day -2, and agree to continue their accepted method of contraception throughout the study.

1. Not of Japanese or Asian descent

2. Parents and grandparents not born in Japan or in any Asian countries Note: Retesting of abnormal lab values that may lead to exclusion will be allowed once.

6. Clinically significant abnormal values for hematology, clinical chemistry, or urinalysis at screening as deemed appropriate by the investigator

7. Clinically significant abnormal physical examination, vital signs or 12 lead ECG at screening as deemed appropriate by the investigator

8. Has a history of human immunodeficiency virus (HIV) antibody positive, or tests positive for HIV; has a history of hepatitis B surface antigen (HBsAg) or hepatitis C antibody (anti-HCV) positive, or other clinically active liver disease, or tests positive for HBsAg or anti-HCV at Screening.

9. Has received an investigational drug or used an invasive investigational medical device within 1 month or within a period less than 10 times the drug's half-life, whichever is longer, before Day 1.
