Study to Investigate the Effect of BL-8040 (Motixafortide) on the QTc Interval in Healthy Subjects

Inclusion Criteria

• Healthy, adult, males and females between the ages of 18 and 55 years, inclusive, at Screening.
• Body weight between 50-109 kg (inclusive) and body mass index (BMI) within 18.0-29.99 kg/m2 (inclusive) at Screening.
• Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs or ECGs, as deemed by the PI or designee.
• Current non-smokers who have not used any nicotine-containing products (chewed or smoked) or replacement products including electronic cigarettes for at least 3 months prior to first dosing.
• Women must meet one of the following criteria: a) postmenopausal; b) surgically sterile; c) of childbearing potential and practicing contraception, as described below:
• Postmenopausal (postmenopausal women must have no menstrual bleeding for at least 1 year prior to first dosing and menopause is confirmed by follicle-stimulating (FSH) levels consistent with postmenopausal status), or
• Surgically sterile (e.g., hysterectomy, bilateral oophorectomy, hysteroscopic sterilization) for at least 6 months prior to first dosing, or
• Women of childbearing potential must be non-lactating and agree to either using a highly effective acceptable form of birth control (e.g., non-hormonal intrauterine device plus condom and spermicide).
• A non-vasectomized, male subject must agree to use a condom with spermicide or abstain from sexual intercourse during the study until 90 days after the last dosing. (No restrictions are required for a vasectomized male provided his vasectomy has been performed 4 months or more prior to the first dosing. A male who has been vasectomized less than 4 months prior to study first dosing must follow the same restrictions as a non-vasectomized male.)
• If male, must agree not to donate sperm from the first dosing until 90 days after the last dosing.
• Understands the study procedures in the informed consent form (ICF), and is willing and able to comply with the protocol.

Exclusion Criteria

• Past or present diseases, which, as judged by the PI or designee, may affect the outcome of this study or pose an additional risk to the subject by their participation in the study, including, but not limited to, significant medical abnormality including: psychiatric, neurologic, pulmonary, cardiac, gastrointestinal, genitourinary, renal, metabolic, endocrinologic, or autoimmune disorder.
• Is mentally or legally incapacitated or has significant emotional problems at the time of the Screening visit or expected during the conduct of the study.
• Positive result for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody at Screening.
• Family history of QTc prolongation or of unexplainable sudden death at 100 bpm at Screening or check-in (Day -2). Minor deviations will be acceptable if considered to be of no clinical significance by the PI or designee.
• Resting supine systolic blood pressure 140 mmHg; resting supine diastolic blood pressure 90 mmHg at Screening or check-in.
• Significant history or presence of ECG findings at Screening or check-in (Day -2), including:
• QTcF >450 msec
• QRS >110 msec, if >110 msec, result will be confirmed by a manual over read
• PR >200 msec
• Second or third-degree atrioventricular (AV) block.
• Significant history or presence of ECG findings as judged by the PI or designee at

Screening or check-in (Day -2), including:

• ECG abnormalities which interfere with accurate QT measurement
• T wave flattening or other abnormalities which in the opinion of the PI (or designee) may interfere with the analysis of QT intervals
• Any rhythm other than sinus rhythm, which is interpreted by the PI (or designee) to be clinically significant.
• Significant safety laboratory abnormalities that would place the subject at undue risk in the PI or designee's opinion, including but not limited to serum alanine aminotransferase (ALT) or serum aspartate aminotransfer
