inclusive);
4. No clinically significant abnormal values on vital signs, B ultrasound and 12-lead
electrocardiogram (ECG). QT interval corrected for heart rate according to
Fridericia's formula (QTcF) must be within the following ranges: QTcF =450 msec for
male subjects, and QTcF =470 msec for female subjects. One repeat assessment is
permitted.
5. Serum uric acid (sUA) level 4 mg/dL (0.24 mmol/L) to 8 mg/dL (0.48 mmol/L) for male
and 3.5 mg/dL (0.21 mmol/L) to 8 mg/dL (0.48 mmol/L) for female during screening;
6. No clinically significant abnormal findings noted during screening for medical history
and physical examination, or clinically significant abnormal results during screening
clinical laboratory tests, including WBC, liver function and kidney function. One
repeat assessment is permitted at the discretion of the Investigator;
7. If male and if engaging in sexual intercourse with a female partner of childbearing
potential, willing to use a condom in addition to having the female partner use a
highly effective method of female contraception (See Section 5.5.3.1) from the time of

to subjects in a same sex relationship or subjects with female partners of
non-childbearing potential. Male subjects must also be willing to not donate sperm for
the same period.

drug, biologic or device within 4 weeks or 5 times the half-life of the specific
drug/biologics (whichever is longer), prior to dosing; 15. Donated blood >400 mL or

months of screening, or donated blood >200 mL or significant blood loss equivalent to
200 mL within 1 month prior to screening; or plans to donate blood during the study;
16. Malignancy within 5 years of screening visit (excluding non-melanoma skin cancer
that has been resected); 17. Recent administration or plans to receive administration
of live vaccine within 12 weeks before Day 1 up to 30 days after the last dose of IP;
18. Use of any other drug, including prescription and over-the-counter medications,
