7. Females of nonchildbearing potential defined as permanently sterile (ie, due to
hysterectomy, bilateral salpingectomy, and/or bilateral oophorectomy) or
postmenopausal (defined as at least 12 months postcessation of menses without an
alternative medical cause and follicle-stimulating hormone [FSH] level = 40 mIU/mL).
Males will agree to use contraception as detailed in protocol.
8. Male subjects must agree to refrain from sperm donation and females should refrain
from ova donation from the date of Check-in (Day -1) until 90 days after the Follow-up
visit.

QRS duration > 110 msec confirmed by repeat measurement. c. PR interval > 220 msec
confirmed by repeat measurement. d. findings which would make QTc measurements difficult or
QTc data uninterpretable. e. history of additional risk factors for torsades de pointes
(eg, heart failure, hypokalaemia, family history of long QT syndrome).
3 (Part B). Clinically significant ECG abnormalities or QTcF greater than 450 msec for

weeks prior to Screening.
11. Subject who, in the opinion of the Investigator (or designee), should not participate
